I was working on a Frappe project where we were building a multi-tenant SaaS platform. The architecture is straightforward: one central Platform app manages tenants, each tenant gets their own dedicated Frappe site with its own database. Complete data isolation, no row-level filtering gymnastics. Clean.

The problem was everything that happened before a tenant could actually use their site. Nothing like manually running around half a dozen bench commands, creating API users, copying credentials into a spreadsheet, and then realizing you typo'd the site name on step three. That was my reality every time a new tenant needed onboarding. Every. Single. Time.

Here's what that checklist looked like:

# Step 1: Create the site
bench new-site tenant-name.localhost --admin-password secret --mariadb-root-password root

# Step 2: Enable developer mode (needed for fixtures)
bench --site tenant-name.localhost set-config developer_mode 1

# Step 3: Install shared library
bench --site tenant-name.localhost install-app shared_lib

# Step 4: Install the tenant app
bench --site tenant-name.localhost install-app tenant_ops

# Step 5: Create an API user for system-to-system communication
bench --site tenant-name.localhost add-system-manager api@example.com --first-name Platform --last-name API

# Step 6: Generate API keys
bench --site tenant-name.localhost execute frappe.core.doctype.user.user.generate_keys --args "['api@example.com']"

# Step 7: Copy the output, paste credentials into Platform... somewhere

Seven steps. Every single time. And if you miss the developer mode step before installing apps, the fixtures don't load and you get to debug that for 20 minutes before realizing what happened.

I decided to automate the whole thing.

The Architecture: One Site Per Tenant

Before getting into the provisioning, a quick note on why the architecture works this way.

Each tenant gets a completely isolated Frappe site: its own database, its own configuration, its own user pool. The Platform hub doesn't store any tenant operational data. It just knows about tenants: their name, their site URL, their status, and the API credentials to talk to them.

Think of it like an apartment building. The management office (Platform) keeps a directory of tenants and handles onboarding. But each apartment (tenant site) has its own lock, its own utilities, and its own stuff inside. The management office doesn't keep a copy of your furniture.

This model gives you real data isolation without any row-level filtering gymnastics. The trade-off is that provisioning a new tenant means creating an actual Frappe site, not just inserting a row. That's why automation matters here.

The Trigger: A Lifecycle Hook

Frappe has lifecycle hooks on every document (DocType). after_insert() fires right after a new record is saved to the database. That's the perfect trigger point.

When someone creates a new Tenant record on the Platform, the hook checks a configuration flag and, if auto-provisioning is enabled, kicks off a background job.

class Tenant(Document):
    def after_insert(self):
        """Enqueue site provisioning after tenant creation (if enabled)."""
        if not frappe.conf.get("auto_provision_tenant_sites", False):
            return  # Manual mode

        frappe.enqueue(
            "platform_hub.jobs.tenant_provisioning_jobs.provision_tenant_site",
            tenant_name=self.name,
            queue="long",
        )
        frappe.msgprint(
            f"Site provisioning started for '{self.tenant_name}'. You'll be notified when complete.",
            indicator="blue",
            alert=True,
        )

A few things I like about this approach:

It's opt-in. The auto_provision_tenant_sites flag lives in common_site_config.json. Set it to false (or don't set it at all), and you're back to manual mode. No code changes needed.

It's non-blocking. frappe.enqueue() pushes the work to a background queue. The user sees a blue notification and can keep working. Site creation takes a minute or two, and you don't want that blocking the request.

It's the "long" queue. Frappe has multiple job queues: default, short, long. Since provisioning runs subprocess commands that can take up to 5 minutes, it belongs in the long queue where timeouts are more generous.

The config is straightforward: three keys in common_site_config.json:

{
  "auto_provision_tenant_sites": true,
  "provision_mariadb_root_password": "your-root-password",
  "provision_admin_password": "initial-admin-password"
}

The Provisioning Service: Seven Steps, One Method Call

The core logic lives in a service class. I like keeping it separate from the DocType controller and the job handler. Each layer has one job.

The orchestration is dead simple:

class TenantProvisioningService:
    def __init__(self, tenant_name: str):
        self._tenant_name = tenant_name
        self._bench_path = get_bench_path()

        # Load config
        self._mariadb_root_password = frappe.conf.get("provision_mariadb_root_password", "")
        self._admin_password = frappe.conf.get("provision_admin_password", "")
        self._api_user = "api@example.com"

        if not self._mariadb_root_password or not self._admin_password:
            frappe.throw(
                "Missing provisioning config. Please set provision_mariadb_root_password "
                "and provision_admin_password in common_site_config.json"
            )

        # Parse site hostname from Tenant's URL
        tenant = frappe.get_doc("Tenant", tenant_name)
        parsed = urlparse(tenant.site_url)
        self._site_name = parsed.hostname

    def provision(self) -> None:
        self._create_site()
        self._enable_dev_mode()
        self._install_app("shared_lib")
        self._install_app("tenant_ops")
        self._create_api_user()
        credentials = self._generate_api_keys()
        self._update_tenant(credentials)
        self._notify_user()

Seven steps. In order. No parallelism needed because each step depends on the previous one. You can't install an app on a site that doesn't exist yet.

Running Bench Commands from Python

Here's where it gets interesting. I'm running bench CLI commands via subprocess, not through Frappe's internal Python APIs.

def _run_command(self, args: list[str], timeout: int = 300) -> subprocess.CompletedProcess:
    result = subprocess.run(
        args,
        capture_output=True,
        cwd=self._bench_path,
        timeout=timeout,
    )

    if result.returncode != 0:
        stdout = result.stdout.decode() if result.stdout else ""
        stderr = result.stderr.decode() if result.stderr else ""
        raise Exception(
            f"Command failed: {' '.join(args)}\n"
            f"Exit code: {result.returncode}\n"
            f"Stdout: {stdout}\n"
            f"Stderr: {stderr}"
        )

    return result

Why subprocess instead of calling Frappe's Python functions directly? Because bench new-site does a lot of heavy lifting: creating a database, setting up the site directory, running initial migrations, installing the core Frappe app. These operations are designed to run as CLI commands, and trying to replicate all of that through internal APIs would be fragile and unnecessary. The CLI is the stable interface here.

The 300-second timeout is generous but necessary. App installation can take a while depending on how many fixtures and migrations need to run.

Each provisioning step is just a thin wrapper around _run_command:

def _create_site(self) -> None:
    self._run_command([
        "bench", "new-site", self._site_name,
        "--admin-password", self._admin_password,
        "--mariadb-root-password", self._mariadb_root_password,
    ])

def _install_app(self, app_name: str) -> None:
    self._run_command([
        "bench", "--site", self._site_name,
        "install-app", app_name,
    ])

def _enable_dev_mode(self) -> None:
    self._run_command([
        "bench", "--site", self._site_name,
        "set-config", "developer_mode", "1",
    ])

The Tricky Part: Parsing API Credentials

Generating API keys is straightforward. Parsing the output? That's where things get a bit creative.

Frappe's generate_keys function prints a Python dict to stdout. Not JSON. A Python dict. So I parse it with ast.literal_eval, which safely evaluates Python literals without executing arbitrary code.

def _generate_api_keys(self) -> dict[str, str]:
    result = self._run_command([
        "bench", "--site", self._site_name,
        "execute", "frappe.core.doctype.user.user.generate_keys",
        "--args", f"['{self._api_user}']",
    ])

    stdout = result.stdout.decode().strip()

    # Parse the dict from output, find the line containing api_key
    for line in stdout.split("\n"):
        line = line.strip()
        if line.startswith("{") and "api_key" in line:
            return ast.literal_eval(line)

    raise Exception(f"Could not parse API credentials from output: {stdout}")

Not the prettiest code I've ever written, but it works reliably. The output format hasn't changed across Frappe versions, and ast.literal_eval is safe: it only parses literals, so no code injection risk.

Storing Credentials and Activating the Tenant

Once we have the API keys, we update the Tenant record and flip its status to Active:

def _update_tenant(self, credentials: dict[str, str]) -> None:
    tenant = frappe.get_doc("Tenant", self._tenant_name)
    tenant.api_key = credentials["api_key"]
    tenant.api_secret = credentials["api_secret"]
    tenant.status = "Active"
    tenant.save()
    frappe.db.commit()

def _notify_user(self) -> None:
    frappe.publish_realtime(
        "msgprint",
        {
            "message": f"Tenant site '{self._site_name}' provisioned successfully!",
            "indicator": "green",
        },
    )

The api_secret field is a Frappe Password type, so it gets encrypted at rest automatically. No extra work needed. And publish_realtime sends a browser notification to whoever created the Tenant, so they know it's done without refreshing the page.

One thing you might notice: I'm calling frappe.db.commit() explicitly here. Normally you don't need to in Frappe because it auto-commits at the end of a request. But this runs inside a background job, not a web request. If the job crashes after save() but before the implicit commit, you'd lose the credentials. The explicit commit makes sure that doesn't happen.

Making It Safe: Idempotency and Error Handling

The background job handler is intentionally thin. Its only responsibilities are the idempotency guard and error logging:

def provision_tenant_site(tenant_name: str) -> None:
    # Guard: Skip if already provisioned
    api_key = frappe.db.get_value("Tenant", tenant_name, "api_key")
    if api_key:
        return

    try:
        service = TenantProvisioningService(tenant_name)
        service.provision()
    except Exception as e:
        frappe.log_error(
            message=str(e),
            title=f"Tenant Provisioning Failed: {tenant_name}",
        )
        raise  # Mark job as failed in RQ

The idempotency guard is simple but important. If api_key already exists on the Tenant, the site was already provisioned. Skip. This prevents duplicate sites if someone retries a job manually, or if the queue somehow dispatches it twice.

The error handling follows a clear pattern. Log the error to Frappe's Error Log DocType (which gives you full stack traces and context in the admin UI), then re-raise the exception. Re-raising is critical: it tells Frappe's job queue (built on Python RQ) that the job failed, so it can retry with exponential backoff.

I considered adding more granular error recovery, like rolling back a half-created site if app installation fails. But let's be honest, for a dev/staging provisioning workflow, the simpler approach works fine. If something fails, you check the Error Log, fix the issue, and the retry usually handles it. No need to over-engineer.

What Happens After: Bidirectional Sync

Provisioning is just the setup. Once the Tenant is Active, the real work begins: the Platform and tenant sites need to stay in sync with each other.

The credentials we stored during provisioning are exactly what makes this possible. The Platform has a dedicated HTTP client that reads the api_key and api_secret from the Tenant record and calls whitelisted API endpoints on the tenant site. The tenant site has its own HTTP client that reads Platform credentials from the bench config and pushes updates back the other way. Both directions are async: background jobs, not inline calls.

The interesting part is preventing sync loops. If Platform pushes a change to the tenant, and the tenant's on_update hook immediately pushes it back, you've got an infinite loop. The solution is clean but not obvious, and there's enough going on with the typed exception hierarchy, the remote_name linking pattern, and the flag-based loop prevention that it deserves its own write-up.

I'm planning a follow-up post that covers the full bidirectional sync implementation. If that's what you came here for, stay tuned.

What This Setup Is and Isn't

Let me be honest about where this approach works and where it doesn't.

This works well when:

• You're running a controlled number of tenants (development, staging, or small-scale production)
• All tenant sites live on the same bench (same server or VM)
• You need real data isolation without the complexity of schema-per-tenant in a shared database
• Your provisioning volume is low-to-moderate (you're not onboarding 100 tenants per hour)

What it's not built for:

• Distributed provisioning. Since we're running bench CLI commands via subprocess, the Platform site and the new tenant site need to be on the same machine. If you need to provision on remote servers, you'd need to swap subprocess for SSH commands or a provisioning API on each server. That's a whole different beast.
• DNS automation. The provisioned site gets a .localhost hostname that needs an /etc/hosts entry. In production, you'd want automated DNS configuration (Route 53, Cloudflare API, etc.). That's not included here.
• Container orchestration. If you're running tenants as separate containers, you'd need Docker API calls instead of bench commands. Same pattern, different execution layer.

The pattern itself transfers to any of those scenarios: lifecycle hook triggers background job, service class runs sequential provisioning steps, credentials get stored back on the source record. The implementation details change, but the architecture stays the same.

What I'd Do Differently Next Time

If I were starting from scratch, I'd add a provisioning_status field on the Tenant record, something like Queued, In Progress, Completed, Failed. Right now the only signals are: does api_key exist (provisioned) or not (pending/failed). That works, but a dedicated status field would make the admin UI much clearer.

I'd also consider generating a unique API user per tenant instead of using a shared system user. Right now all tenant sites use the same API email address. It works, but per-tenant credentials would make it easier to revoke access for a single tenant without affecting others.

So yeah, that's the setup. One Tenant record, one background job, and you've got a fully configured SaaS site with API credentials, ready for bidirectional sync. The whole flow takes about 90 seconds end to end, and the admin doesn't have to touch the terminal.

If there's interest, I might write a follow-up about the bidirectional sync in more detail, you know, field mapping strategies, error recovery, and what happens when one side is down while the other keeps pushing updates. Because that's where multi-tenant architectures get really interesting 🚀

As some of you might know, I'm from Sri Lanka and English isn't my first language. So as a software engineer who basically lives inside Claude Code, typing 50+ prompts a day, you can imagine how many grammatically questionable sentences I produce. 😅

And I've lost count of how many times I've looked back at a prompt I just wrote and thought, "wow, that grammar is terrible." Or worse, the grammar is fine but the whole sentence just sounds unnatural. I can tell it sounds off. I know a native speaker wouldn't phrase it that way. But I don't have time to figure out what the actual error is, why it sounds weird, or how someone would naturally say it. I have code to ship, so I move on and tell myself I'll fix my English later.

Later never comes. You know how it goes. 🤷‍♂️

But here's the thing. Those 50+ prompts I type every day? They're real English sentences. Not textbook exercises. Not "the cat sat on the mat." They're messy, fast, and authentic. And that's actually perfect practice material.

So I built a system using Claude Code's UserPromptSubmit hook that silently analyzes every prompt I type for grammar mistakes and unnatural phrasing, rewrites it in clean English, and shows me how a native speaker would actually say the same thing. All logged to a file I can review later. It runs entirely in the background, never touches my coding session, and costs nothing extra on top of my Claude Max plan.

If you've been looking for a practical, real-world use case for Claude Code hooks, this is a fun one. And if you're a non-native speaker, you get to improve your English as a side effect.

The Idea in One Sentence

Every time I submit a prompt in Claude Code, a hook catches it, sends it to a separate claude --print process for grammar analysis, and appends the result to a grammar-log.md file in my project. My main coding session has zero idea this is happening.

How Claude Code Hooks Work (Quick Version)

If you haven't played with Claude Code hooks yet, the short version: they're scripts that run automatically at specific points in Claude Code's lifecycle. You configure them in your .claude/settings.json, and they fire when certain events happen.

The one we care about is UserPromptSubmit. It fires the moment you hit enter on a prompt, before Claude even starts processing it. The hook receives your prompt text as JSON on stdin (something like {"prompt": "your prompt text here", ...}), which means we can grab it, do whatever we want with it, and let the main session continue like nothing happened.

If you want the full picture on what hooks can do, check out the official hooks documentation. What I'm covering here is just one practical use case, but by the end of this post you'll have a solid idea of how hooks work and the kind of things you can build with them.

The Architecture

Here's the full flow:

You type a prompt in Claude Code
        │
        ▼
UserPromptSubmit hook fires (grammar-check.py)
        │
        ├── Is GRAMMAR_COACH_ACTIVE env var set?
        │     YES → exit immediately (recursion guard)
        │     NO  → continue
        │
        ├── Should we skip this? (< 5 words, slash command, pure code)
        │     YES → exit
        │     NO  → continue
        │
        ├── Clean the prompt (strip backslashes from line breaks)
        │
        ├── Spawn background process:
        │     claude --print [grammar analysis prompt]
        │     - runs from /tmp (no project context)
        │     - env: GRAMMAR_COACH_ACTIVE=1
        │     - stdout → appends to grammar-log.md
        │     - fully detached from main session
        │
        └── exit(0) - main agent sees nothing

Two things worth highlighting here.

First, the background process runs from /tmp, not your project directory. This is important. If it runs from your project, it picks up your CLAUDE.md, your project context, everything. And instead of analyzing your grammar, it tries to execute your prompt as a coding task. Running from /tmp means it has zero context. It just sees text and analyzes English.

Second, the GRAMMAR_COACH_ACTIVE environment variable. I'll explain this one in detail because it's a pattern worth knowing.

The Recursion Problem (And How One Env Var Fixes It)

When the hook spawns claude --print in the background, that new CLI process loads ~/.claude/settings.json, which has the same UserPromptSubmit hook configured. So the hook fires again. Which spawns another claude --print. Which loads the settings. Which fires the hook again. Infinite loop.

The fix is an environment variable used as a signal between parent and child processes.

Think of environment variables as sticky notes attached to a process. Every program on your computer carries its own set. When a process creates a child, the child gets a copy of the parent's sticky notes.

So the hook does two things:

1. Before spawning the background process, it sets GRAMMAR_COACH_ACTIVE=1 in the child's environment

2. At the very top of the script, it checks: is GRAMMAR_COACH_ACTIVE set to "1"? If yes, exit immediately

The parent process (your Claude Code session) never has this variable. So the hook always runs for your real prompts. But when the background claude --print triggers the hook, the hook sees the variable and exits. Loop broken. One entry per prompt, every time.

This "env var as a flag" pattern shows up everywhere in software. CI=true in pipelines, NODE_ENV=production in Node apps, DEBUG=1 for verbose logging. Same idea here, just applied to recursion prevention.

Let's Build It: The Full Setup

What You Actually Get

After a few prompts, your grammar-log.md starts filling up. Here's a real entry from my log:

## 2026-02-07 20:22

**Original prompt:**
> hey claude, i have mass of data coming from the API and
> its very slow to render them in the frontend. can you
> suggest me a better approach for handle this?

**Grammar & language issues:**
- **"mass of data"** → **"a large amount of data"** -
  "Mass of data" sounds unnatural. "A large amount of data"
  or "a lot of data" is more standard.
- **"its"** → **"it's"** -
  "It's" (with apostrophe) is the contraction for "it is."
  "Its" without apostrophe is possessive.
- **"render them"** → **"render it"** -
  "Data" is treated as singular in everyday English,
  so use "it" not "them."
- **"suggest me a better approach"** → **"suggest a better approach"** -
  In English, "suggest" doesn't take an indirect object this way.
  You suggest something (to someone), not suggest someone something.
- **"for handle this"** → **"for handling this"** -
  After a preposition ("for"), use the gerund form ("handling"),
  not the base form ("handle").

**Natural rewrite:**
> Hey Claude, I have a large amount of data coming from the API

Three sections per entry. The "issues" section tells me what I got wrong and why. The "natural rewrite" shows me the polished written version. And the "how a native speaker would say this" section? That's my favorite. It shows me how a dev would actually say the same thing to a colleague. Casual, contracted, real.

The hook is smart enough to skip stuff that isn't worth analyzing: prompts under 5 words, slash commands, memory notes, and anything that's mostly code. And it deliberately ignores capitalization. I know the rules, I just don't have time for shift keys when I'm deep in a coding session.

Where It Gets Interesting: Analyzing Your Patterns

Here's where this setup goes from "nice trick" to something genuinely useful for language learning.

After a few weeks of coding, your grammar-log.md files will have hundreds of entries. That's a gold mine of data about your actual English patterns. Not textbook exercises, but real sentences you wrote while thinking about real problems.

Create a Claude Project specifically for grammar analysis. Drag your grammar-log.md files from different projects into it. Give the project instructions like "analyze these grammar logs, find recurring mistake patterns, track which errors are decreasing over time, and identify my weakest areas."

Now you can ask things like:

• "What are my top 5 most common grammar mistakes?"

• "Am I getting better at using prepositions? Compare my first 50 entries to my last 50."

• "Which verb tense errors keep showing up?"

• "Give me a focused practice session based on my three worst patterns."

You could take it further. Set up a weekly review routine. Every Friday, drag in that week's logs and get a progress snapshot. Compare patterns across different projects to see if certain types of work trigger certain mistakes. Turn your worst recurring errors into flashcard-style drills. Or feed your pattern analysis back into a custom CLAUDE.md file so Claude starts nudging you about your specific weak spots during coding sessions.

And honestly, that's just what I've thought of so far. The grammar logs are just structured data about your English. Once you have that data, you can get as creative as you want with it.

Setup in Two Minutes

If you want to try this yourself:

# Create the hooks directory
mkdir -p ~/.claude/hooks

# Save grammar-check.py (from above) to:
# ~/.claude/hooks/grammar-check.py

# Make it executable
chmod +x ~/.claude/hooks/grammar-check.py

# Add the hooks config to ~/.claude/settings.json

# Optional: add grammar-log.md to your project's .gitignore
# if you don't want it committed
echo "grammar-log.md" >> .gitignore

# Restart Claude Code - done

Before setting up the hook, make sure claude --print "hello" works in your terminal. If it responds, you're good. This also assumes you have Python 3 installed, which most macOS and Linux systems already do.

After setup, just code normally. Give it 15-20 seconds after your first prompt, then check grammar-log.md in your project root. If an entry showed up, everything's working.

What's Next

I'm planning to run this for a few months and accumulate enough data to do a proper pattern analysis. The goal is to find out which types of mistakes actually decrease over time (just from seeing the corrections) and which ones need focused practice.

If there's interest, I might write a follow-up showing what the pattern analysis looks like after a month of real usage. You know, actual error rates, which grammar areas improved, and whether passive learning from a log file actually translates to better English.

So yeah, every prompt is a rep. And when you're typing 50+ of them a day, that adds up fast.

Happy coding, and happy (unintentional) grammar practice. 😅

See you in the next one.

Series Navigation:

• Part 0: Introduction - Why This Setup?

• Part 1: Containerizing Strapi v5

• Part 2: Deploying to DigitalOcean

• Part 3: Production Web Server Setup

• Part 4: Automated Database Backups

• Part 5a: CI Pipeline with GitHub Actions

• Part 5b: CD Pipeline and Deployment Automation (You are here)

New to the series? Start with Part 5a to get the CI pipeline working first - this article builds directly on that foundation.

Alright, we've got automated validation working from Part 5a. Every time you push code, GitHub Actions gives you that green checkmark telling you everything's good to go. Feels nice, right?
But here's what's still manual: actually deploying that validated code to your staging server.

Right now, if you pushed the locally build docker image to GHCR, you're still:

1. SSHing into your server

2. Pulling the latest image from GHCR

3. Updating docker-compose files

4. Restarting containers

5. Checking if everything works

6. Manually rolling back if something breaks

That's fine for deploying once a week. But when you're iterating quickly? This becomes a bottleneck fast. And if you deploy monthly or even less frequently? Good luck remembering all these steps without checking your notes every single time. "Wait, did I update the compose file first or pull the image first? And what was that health check command again?"

In this article, we're completing the automation by building the CD (Continuous Deployment) part of the pipeline. We'll create TWO workflow options so you can choose the approach that fits your team:

Option 1 - Auto-Deploy on Merge (Recommended for teams):

• Triggers automatically when code is merged to dev

• Builds Docker image and pushes to GHCR

• Requires manual approval before deploying

• Perfect for teams that want safety gates

• Prevents accidental deployments

Option 2 - Manual-Dispatch Workflow (Great for small teams):

• Trigger deployment from ANY branch via GitHub workflow UI

• Trigger deployment from ANY Git Tag via Github workflow UI

• No approval needed (you're already being intentional)

• Perfect for testing feature branches in staging

• Great for solo developers or tight-knit teams

• Ideal for emergency hotfixes

By the end, you'll have a complete CI/CD pipeline where validated code automatically (or manually) deploys to your staging environment with health checks, rollback capabilities, and clear visibility into what's happening.

Let's build this.

What We're Building

Here's the complete deployment flow for both options:

Auto-Deploy Workflow (staging-deploy.yml):

Merge to dev → Security scan → Build & push to GHCR → Wait for approval 
→ Deploy to server → Health check → Success or auto-rollback

Perfect for:

• Teams with multiple developers

• When you want review gates before deployment

• Preventing accidental staging updates

• Learning proper DevOps practices

Manual-Dispatch Workflow (staging-deploy-manual.yml):

Click "Run workflow" → Select branch → Security scan → Build & push to GHCR 
→ Deploy to server → Health check → Success or auto-rollback

Perfect for:

• Solo developers or small teams (2-3 people)

• Testing feature branches in staging before merging

• Emergency hotfixes that need speed

• When you want full control without approval gates

Both workflows deploy to the same staging environment (your DigitalOcean droplet from Parts 1-4). The only difference is the trigger mechanism and approval process.

Future Extensibility:

While this article focuses on deploying to a single staging environment, these workflows are highly extensible:

• Multi-environment support: You can create separate workflows for staging, UAT, and production environments

• Environment selector: The manual workflow can be extended to show a dropdown where you select which environment to deploy to

• Different approval requirements: Production might require 2 approvers, staging might require 1 or none

• Environment-specific configurations: Each environment can have different resource limits, environment variables, etc.

We'll stick with a single staging environment for this article to keep things clear, but I'll show you where to add these features when you're ready to scale up.

Prerequisites

Before we start, make sure you have:

• Part 5a completed (CI pipeline running and working)

• Parts 1-4 completed (Strapi deployed on DigitalOcean)

• SSH access to your staging server

• Admin access to your GitHub repository

• About 90-120 minutes for complete setup and testing

Quick check - Is your CI working?

If you push code to a feature branch, do you see the workflow run in GitHub Actions? If yes, you're ready. If not, go back to Part 5a and get that working first.

Understanding the Deployment Architecture

Before we dive into configuration, let's understand what happens during deployment:

Current State (Manual Deployment):

Local Machine → SSH to server → Pull image → Update compose → Restart → Hope

After Part 5b (Automated Deployment):

GitHub Actions → Builds image → Pushes to GHCR → SSH to server 
→ Server pulls image → Creates backup → Updates compose → Deploys 
→ Health check → Success or auto-rollback

Key Components:

1. GitHub Container Registry (GHCR): Where we store production Docker images

2. GitHub Secrets: Secure storage for SSH keys and server credentials

3. GitHub Environments: Approval gates and environment-specific settings

4. Deployment Script: Lives on your server, handles the actual deployment

5. Health Checks: Verify deployment succeeded before considering it complete

6. Rollback Mechanism: Automatically reverts if deployment fails

Why this architecture works:

• GitHub Actions handles orchestration (building, approval, triggering)

• Your server handles deployment (it knows its own state best)

• Clear separation of concerns

• Easy to debug (logs in both GitHub and on server)

• Can scale to multiple environments

Step 1: Create SSH Key for Deployment

First, we need a way for GitHub Actions to SSH into your staging server and trigger deployments.

Generate a New SSH Key

On your local machine:

# Create a dedicated SSH key for GitHub Actions
ssh-keygen -t ed25519 -f ~/.ssh/github_actions_staging -N ""

# This creates two files:
# ~/.ssh/github_actions_staging (private key - for GitHub)
# ~/.ssh/github_actions_staging.pub (public key - for server)

Why a separate key?

• Dedicated key for automation (different from your personal key)

• Easy to revoke if compromised

• Clear audit trail of automated vs manual access

• Follows principle of least privilege

Add Public Key to Your Server

Copy the public key to your server:

# Method 1: Via Root User (Recommended for Fresh Servers)
# Use this if you only have root SSH access (typical for new servers)
cat ~/.ssh/github_actions_staging.pub | ssh root@YOUR_STAGING_SERVER_IP \
  "mkdir -p /home/deploy/.ssh && \
   cat >> /home/deploy/.ssh/authorized_keys && \
   chown -R deploy:deploy /home/deploy/.ssh && \
   chmod 700 /home/deploy/.ssh && \
   chmod 600 /home/deploy/.ssh/authorized_keys"

# Method 2: Direct to Deploy User (If You Already Have Access)
# Use this if you can already SSH as deploy user (password or existing key)
ssh-copy-id -i ~/.ssh/github_actions_staging.pub deploy@YOUR_STAGING_SERVER_IP

Why Method 1 is often needed:

• Fresh servers typically only allow root SSH access initially

• Production servers often have password authentication disabled

• This creates the directory, adds the key, and sets correct permissions in one command

Important: We're adding the key for the deploy user (from Part 2), not root. This maintains proper security practices.

Test the SSH Connection

# Test the new key works
ssh -i ~/.ssh/github_actions_staging deploy@YOUR_STAGING_SERVER_IP

# You should get in without a password prompt
# If it works, exit the server:
exit

Get the Private Key for GitHub

# Display the private key
cat ~/.ssh/github_actions_staging

# Copy the ENTIRE output including:
# -----BEGIN OPENSSH PRIVATE KEY-----
# [all the key content]
# -----END OPENSSH PRIVATE KEY-----

Save this somewhere temporarily - we'll add it to GitHub Secrets in the next step.

Security Note:

This private key is powerful - it grants access to your server. Keep it secure:

• Don't commit it to Git

• Don't paste it in Slack or email

• Don't share it publicly

• Store it only in GitHub Secrets (which we'll do next)

Step 2: Add GitHub Secrets

GitHub Secrets provide secure storage for sensitive information like SSH keys and server credentials.

Navigate to Repository Secrets

1. Go to your GitHub repository

2. Click Settings (top menu)

3. Click Secrets and variables → Actions (left sidebar)

4. Click New repository secret

Add These Three Secrets

Secret 1: STAGING_SSH_KEY

• Name: STAGING_SSH_KEY

• Value: Paste the entire private key from Step 1

    -----BEGIN OPENSSH PRIVATE KEY-----
    [your entire private key content]
    -----END OPENSSH PRIVATE KEY-----
  

• Click Add secret

Secret 2: STAGING_HOST

• Name: STAGING_HOST

• Value: Your staging server IP address (e.g., 167.99.234.123)

• Click Add secret

Secret 3: STAGING_USER

• Name: STAGING_USER

• Value: deploy

• Click Add secret

Verify Secrets Are Added

You should now see three secrets listed:

STAGING_SSH_KEY
STAGING_HOST
STAGING_USER

Note: You can't view secret values after creation (security feature). If you made a mistake, delete and recreate the secret.

Why These Specific Names?

The STAGING_ prefix makes it clear these are for staging environment. When you add production later, you'll create PRODUCTION_SSH_KEY, PRODUCTION_HOST, etc. This naming convention prevents accidentally deploying to the wrong environment.

Step 3: Create Deployment Script on Server

Now let's create the script that actually handles deployment on your server. This script will be called by GitHub Actions but runs locally on your server.

Connect to Your Server

ssh deploy@YOUR_STAGING_SERVER_IP
cd /opt/strapi-backend

Create Deployment Scripts Directory

# Create directory for deployment scripts
mkdir -p deployment-scripts
chmod 755 deployment-scripts

Create the Deployment Script

nano deployment-scripts/deploy-staging.sh

Paste this complete script:

Save and exit (Ctrl+X, Y, Enter).

Update Script Configuration

Now customize the script for your setup:

# Edit the script again
nano deployment-scripts/deploy-staging.sh

Update these critical configuration sections:

# Lines 14-16: File paths (usually these are correct as-is)
COMPOSE_FILE="/opt/strapi-backend/docker-compose.stg.yml"
ENV_FILE="/opt/strapi-backend/.env.stg"
BACKUP_DIR="/opt/strapi-backend/backups"

# Lines 19-22: Database configuration - MUST MATCH YOUR SETUP
DATABASE_NAME="strapi_staging"     # Change to YOUR database name (from .env.stg)
DATABASE_USER="postgres"           # Usually "postgres", but verify in .env.stg
DATABASE_CONTAINER="strapiDB"      # Change to YOUR database service name
STRAPI_CONTAINER="strapi-backend"  # Change to YOUR Strapi service name

# Lines 24-27: Docker image configuration
DOCKER_REGISTRY="ghcr.io"                    # Keep as-is for GitHub Container Registry
GITHUB_USERNAME="your-github-username"       # Change to YOUR GitHub username (lowercase)
REPO_NAME="your-repo-name"                   # Change to YOUR repository name (lowercase)

# Lines 29-30: Health check configuration (optional adjustments)
HEALTH_CHECK_URL="http://localhost:1337/admin"  # Keep unless you changed Strapi port
HEALTH_CHECK_TIMEOUT=45                          # Seconds to wait for health check

How to find your configuration values:

# 1. Find your database name
grep "DATABASE_NAME" .env.stg
# Example output: DATABASE_NAME=strapi_staging

# 2. Find your database user
grep "DATABASE_USERNAME" .env.stg
# Example output: DATABASE_USERNAME=postgres

# 3. Find your service names from docker-compose.stg.yml
grep "^  [a-zA-Z]" docker-compose.stg.yml
# Example output:
#   strapi-backend:    ← This is your STRAPI_CONTAINER
#   strapiDB:          ← This is your DATABASE_CONTAINER

# 4. Verify your GitHub username and repo name
# Should match your GHCR image URL: ghcr.io/YOUR_USERNAME/YOUR_REPO

Important Notes:

• DATABASE_NAME: Must match exactly what's in your .env.stg file

• DATABASE_USER: Usually "postgres" but check your .env.stg to be sure

• Service names: Use the service name from docker-compose.stg.yml, NOT the container_name

• GitHub username/repo: Must be lowercase (GHCR requirement)

Make the script executable:

chmod +x deployment-scripts/deploy-staging.sh

Understanding the Deployment Script

Let's walk through what this production-ready script does:

1. Configuration Section (Lines 8-33):

Everything you need to customize is clearly marked at the top:

• File paths for compose files, backups, and logs

• Database configuration (name, user, container)

• Docker image registry settings

• Health check parameters

Why this matters: No more hunting through the script to find hardcoded values. All configuration is in one place.

2. Utility Functions:

• log() - Timestamps and logs every action to deployment.log

• error_exit() - Logs error and exits cleanly

• show_usage() - Displays help text when script is used incorrectly

• get_current_version() - Reads currently deployed version from docker-compose

• record_deployment() - Tracks deployment history with timestamp, version, and status

3. Deployment Functions:

• create_backup() - Creates pre-deployment database backup with version-specific naming

• update_compose_file() - Safely updates docker-compose.stg.yml with new image version

• health_check() - Verifies Strapi responds correctly after deployment (45-second timeout)

• rollback() - Automatically reverts to previous version if deployment fails

4. Main Deployment Flow:

1. Validate input (requires version tag)
2. Create pre-deployment database backup
3. Pull new Docker image from GHCR
4. Update docker-compose.stg.yml with new version
5. Stop Strapi container (NOT database - prevents downtime)
6. Start Strapi with new version
7. Wait 30 seconds for startup
8. Run health check (45 attempts)
9. On success: Log success, record to history, clean up
10. On failure: Automatic rollback to previous version

5. Key Safety Features:

• set -e - Script exits immediately on any error

• Pre-deployment backup - Always creates backup before touching anything

• Compose file backup - Saves old docker-compose before modification

• Selective restart - Only restarts Strapi, not database (faster, less risky)

• Automatic rollback - If health check fails, reverts automatically

• Deployment history - Tracks all deployments in deployment-history.txt

6. CLI Features:

# Show currently deployed version (useful for debugging)
./deployment-scripts/deploy-staging.sh --current

# Show help message
./deployment-scripts/deploy-staging.sh --help

# Deploy specific version
./deployment-scripts/deploy-staging.sh v20241208-143052-a1b2c3d

Why this script is production-ready:

• ✅ Configurable: Works with any database name, container name, or setup

• ✅ Safe: Automatic backups and rollbacks

• ✅ Observable: Comprehensive logging and deployment history

• ✅ Fast: Only restarts Strapi, not the database

• ✅ Reliable: Health checks verify deployment actually worked

• ✅ User-friendly: CLI flags make it easy to use and debug

This is the same script running successfully in production environments, not a simplified tutorial version.

Test the Script Manually

Before using it in automation, let's verify it works:

# Check currently deployed version
./deployment-scripts/deploy-staging.sh --current
# Should show: Currently deployed version: v2.0.0-rc1

# Get help
./deployment-scripts/deploy-staging.sh --help

# Test actual deployment (use your current version first)
./deployment-scripts/deploy-staging.sh v2.0.0-rc1

# Watch the logs
tail -f /opt/strapi-backend/deployment.log

Expected output:

==========================================
DEPLOYMENT STARTED
==========================================
Current version: v2.0.0-rc1
New version: v2.0.0-rc1

Creating pre-deployment backup...
Backup created: predeployment_v2.0.0-rc1_20241208_143052.sql.gz
Pulling Docker image: v2.0.0-rc1
✅ Docker image pulled successfully
Updating docker-compose.stg.yml with version: v2.0.0-rc1
docker-compose.stg.yml updated successfully
Deploying new version...
Stopping Strapi container...
Starting new version...
Waiting for Strapi to start...
Running health checks...
✅ Health check passed!
==========================================
✅ DEPLOYMENT SUCCESSFUL
==========================================
Version v2.0.0-rc1 is now live
Backup available at: predeployment_v2.0.0-rc1_20241208_143052.sql.gz

Check deployment history:

cat /opt/strapi-backend/deployment-history.txt
# Should show:
# 2024-12-08 14:30:52 | v2.0.0-rc1 | SUCCESS

If it fails:

Check the deployment log:

tail -50 /opt/strapi-backend/deployment.log

Once the script runs successfully, you're ready to automate it with GitHub Actions!

Step 3.5: Create Rollback Script

While the deployment script has automatic rollback for failed deployments, you also need a manual rollback script for situations like:

• Bug discovered hours after deployment

• Need to rollback just the app or just the database

• Checking deployment status and history

Create the rollback script:

nano deployment-scripts/rollback-staging.sh

Paste this complete script:

#!/bin/bash
# ============================================================================
# Rollback Script for Strapi v5 Staging
# Capabilities: App rollback, Database rollback, Status check
# ============================================================================

set -e

# ============================================================================

Update Rollback Configuration

Update these variables to match your deployment script:

nano deployment-scripts/rollback-staging.sh

Find and update:

DATABASE_NAME="strapi_staging"     # Must match .env.stg
GITHUB_USERNAME="your-github-username"   # Your GitHub username (lowercase)
REPO_NAME="your-repo-name"               # Your repository name (lowercase)

How to find your values:

# Database name
grep DATABASE_NAME .env.stg

# Check docker-compose for service names
grep "container_name:" docker-compose.stg.yml

Test the Rollback Script

Check current status:

./deployment-scripts/rollback-staging.sh status

Expected output:

==========================================
CURRENT STATUS
==========================================

Current Version:
  v20241208-120000-abc1234

Container Status:
NAME              IMAGE                                    STATUS
strapi-backend    ghcr.io/you/your-repo:v20241208...      Up
strapiDB          postgres:16-alpine                       Up

Recent Deployment History:
2024-12-08 12:00:15 | v20241208-120000-abc1234 | SUCCESS
2024-12-08 14:30:22 | v20241208-143000-def5678 | SUCCESS

Available Rollback Versions:
  v20241208-120000-abc1234
  v20241208-143000-def5678

Available Database Backups:
-rw-r--r-- 1 deploy deploy 4.2M Dec  8 14:30 predeployment_v20241208_143052.sql.gz
-rw-r--r-- 1 deploy deploy 4.1M Dec  8 12:00 predeployment_v20241208_120015.sql.gz

Rollback Commands

Rollback app to previous version:

./deployment-scripts/rollback-staging.sh app

Rollback app to specific version:

./deployment-scripts/rollback-staging.sh app v20241208-120000-abc1234

Rollback database only:

./deployment-scripts/rollback-staging.sh database predeployment_v20241208_143052.sql.gz

Full rollback (app + database):

./deployment-scripts/rollback-staging.sh full

Why this script is important:

The deployment script has automatic rollback for failed deployments, but this separate rollback script is essential for:

• Manual rollbacks when bugs are discovered hours/days later

• Selective rollbacks - app-only or database-only

• Status checking - see what's deployed and available rollback options

• Emergency recovery - quick access to all rollback capabilities

Step 4: Create Auto-Deploy Workflow (Primary Option)

This workflow automatically deploys when code is merged to dev but requires manual approval before deployment actually happens.

Create the Workflow File

On your local machine, in your project:

# Make sure .github/workflows directory exists
mkdir -p .github/workflows

# Create the auto-deploy workflow
nano .github/workflows/staging-deploy.yml

Paste this complete workflow:

Understanding the Auto-Deploy Workflow

Let's break down the key parts:

Trigger Configuration:

on:
  push:
    branches:
      - dev

This workflow runs automatically when code is pushed to (or merged into) the dev branch. Every merge to dev triggers a deployment attempt.

Setup Job (Lowercase Conversion):

setup:
  steps:
    - name: 🔄 Convert to lowercase
      run: |
        echo "repository_owner=$(echo '${{ github.repository_owner }}' | tr '[:upper:]' '[:lower:]')" >> $GITHUB_OUTPUT

Why we need this:

Docker registries require lowercase names, but GitHub usernames and repo names can have uppercase letters. This job converts everything to lowercase and makes it available to other jobs via outputs.

Without this conversion:

• GitHub username: YourGitHubUsername

• Docker tries: ghcr.io/YourGitHubUsername/repo → FAILS (uppercase not allowed)

• With conversion: ghcr.io/your-github-username/repo → WORKS

Version Generation:

- name: 🔢 Generate version tag
  run: |
    VERSION="v$(date +'%Y%m%d-%H%M%S')-$(git rev-parse --short HEAD)"

Format: v20241215-143052-a7f3d2c

This creates a unique version for every deployment:

• 20241215 - Date (December 15, 2024)

• 143052 - Time (14:30:52)

• a7f3d2c - Git commit hash (short)

Why this format?

• Chronological sorting (newest versions sort last)

• Includes timestamp (know exactly when it was built)

• Includes commit hash (trace back to exact code)

• Automatically unique (no version conflicts)

Approval Gate (Issue-Based - Free Tier Compatible):

approval:
  name: ⏸️ Wait for Approval
  steps:
    - uses: trstringer/manual-approval@v1
      with:
        approvers: ${{ needs.setup.outputs.approvers }}
        minimum-approvals: 1

How the approval workflow works:

1. Workflow pauses after the build completes

2. GitHub Issue is automatically created with deployment details

3. Approvers get notified (anyone watching the repo sees the issue)

4. Approvers comment /approve, approved, or lgtm on the issue

5. Workflow continues to deployment after approval

6. Auto-cancels after 6 hours if no response

This approval method works on GitHub Free tier because it uses Issues (available on all tiers) instead of Environment protection rules (which require GitHub Pro/Team for required reviewers).

deploy:
  needs: [setup, build, approval]  # Waits for approval before running
  # Note: No 'environment: staging' - using issue-based approval instead

The deploy job won't start until the approval job completes successfully.

We'll show you how to configure Environment-based approvals (for Pro/Team users) in Step 6.

Step 5: Create Manual-Dispatch Workflow (Bonus Option)

This workflow can be triggered manually from any branch, giving you full control over what gets deployed and when.

Create the Workflow File

# On your local machine
nano .github/workflows/staging-deploy-manual.yml

Paste this complete workflow:

Key Differences from Auto-Deploy:

1. Trigger Mechanism:

on:
  workflow_dispatch:
    inputs:
      version:
        description: 'Version tag (leave blank for auto)'
        required: false

• workflow_dispatch means "run when someone clicks the button"

• inputs provides optional version override

• Can be triggered from ANY branch (not just dev)

2. No Approval Required:

deploy:
  name: 🚀 Deploy to Staging
  # Note: No 'environment: staging' line

The absence of environment: staging means the workflow runs immediately after the build completes. No approval gate.

Why skip approval for manual workflows?

You're already being intentional by clicking "Run workflow" and selecting a branch. Adding an approval gate on top of that is redundant. The manual action itself is the approval.

3. Optional Version Input:

if [ -z "${{ inputs.version }}" ]; then
  VERSION="v$(date +'%Y%m%d-%H%M%S')-$(git rev-parse --short HEAD)"
else
  VERSION="${{ inputs.version }}"
fi

You can either:

• Leave version blank → Auto-generates v20241215-143052-a7f3d2c

• Provide custom version → Uses v2.0.0-beta1 or whatever you enter

This is useful when you want meaningful version names for specific releases.

Step 6: Configure Deployment Approval

The auto-deploy workflow includes a manual approval gate to prevent accidental deployments. There are two ways to set this up, depending on your GitHub plan.

Understanding GitHub Free Tier Limitations

GitHub Free tier:

• ✅ Environments exist and work

• ✅ Can create "staging" environment

• ❌ Cannot add "Required reviewers" to environments

• ❌ Environment protection rules require GitHub Pro or Team

GitHub Pro/Team:

• ✅ Everything Free tier has

• ✅ Can add Required reviewers

• ✅ Full environment protection rules

• ✅ More sophisticated approval workflows

Since this is a $6/month series, most readers will be on GitHub Free tier. We'll show you both approaches.

Approach 1: Issue-Based Approval (Free Tier) ✅ Recommended

This is what the workflow already uses. The approval happens through GitHub Issues, which work on all GitHub plans.

How It Works:

1. Workflow pauses after build completes

2. GitHub Issue is created automatically with title like "🚀 Deploy v20241215-143052 to Staging?"

3. Issue includes deployment details: version, branch, commit, who triggered it

4. Approver comments on the issue: /approve, approved, or lgtm

5. Workflow continues to deployment after approval received

6. Auto-cancels after 6 hours if no response

7. Issue closes automatically after workflow completes

Required Permissions (Already Configured):

The workflow already has these permissions set:

permissions:
  contents: read
  packages: write
  issues: write        # Required for creating approval issues
  pull-requests: write # Required for approval action

Configure Approvers:

Update the approvers list in the workflow:

env:
  NODE_VERSION: '20'
  REGISTRY: 'ghcr.io'
  APPROVERS: 'your-github-username'  # UPDATE THIS!

To add multiple approvers:

APPROVERS: 'alice,bob,charlie'  # Comma-separated, no spaces

That's it! The issue-based approval is already configured and will work immediately.

Approach 2: Environment-Based Approval (Requires GitHub Pro/Team)

If you have GitHub Pro or Team (or Enterprise), you can use Environment protection rules for a more integrated approval experience.

Step 1: Create the Staging Environment

1. Go to your GitHub repository

2. Click Settings (top menu)

3. Click Environments (left sidebar)

4. Click New environment

5. Name: staging

6. Click Configure environment

Step 2: Configure Environment Protection Rules

On the staging environment configuration page:

1. Required reviewers:

• Check ✅ "Required reviewers"

• Add yourself (or team members who can approve deployments)

• You can add up to 6 reviewers

• Deployment requires approval from at least 1 reviewer

2. Wait timer:

• Leave unchecked (no delay needed for staging)

• This feature is useful for production (e.g., "wait 5 minutes before deploying")

3. Deployment branches:

• Select "Selected branches"

• Click "Add deployment branch rule"

• Pattern: dev

• This ensures only the dev branch can deploy to staging

Click Save protection rules.

Step 3: Modify the Workflow

Replace the approval job with the environment setting:

# Remove the entire approval job (lines with trstringer/manual-approval)
# Instead, add environment to the deploy job:

deploy:
  name: 🚀 Deploy to Staging
  runs-on: ubuntu-latest
  needs: [setup, build]  # Remove 'approval' from needs
  environment: staging   # Add this line

Also remove these permissions (not needed for environment-based):

# Remove these lines:
  issues: write
  pull-requests: write

How Environment-Based Approval Works:

1. Workflow triggers (merge to dev)

2. Security scan passes

3. Docker image builds and pushes to GHCR

4. Workflow pauses at deploy job (because of environment: staging)

5. GitHub shows "Waiting for review" status

6. Reviewer gets notification

7. Reviewer clicks "Review pending deployments" in Actions tab

8. Reviewer approves or rejects

9. If approved → Deployment continues

10. If rejected → Deployment cancels

Advantages over Issue-based:

• Integrated into GitHub Actions UI

• Shows deployment history in Environment page

• More sophisticated branch rules

• Better for teams with strict deployment policies

For this $6/month series: Stick with Issue-Based Approval (Approach 1). It's already configured and works perfectly.

Step 7: Commit and Push Both Workflows

Now let's activate both workflows:

# On your local machine
# Make sure you're on dev branch
git checkout dev

# Add both workflow files
git add .github/workflows/staging-deploy.yml
git add .github/workflows/staging-deploy-manual.yml

# Commit
git commit -m "Add CD pipelines for staging deployment"

# Push to dev branch
git push origin dev

What happens next:

1. Auto-deploy workflow triggers immediately (because you pushed to dev)

2. You'll see "🚀 Deploy to Staging (Auto)" running in GitHub Actions

3. Manual workflow is now available but won't run until you trigger it

Let's watch the auto-deploy workflow first since it just started!

Step 8: Test the Auto-Deploy Workflow

The workflow is running right now. Let's watch it and approve the deployment.

Monitor the Workflow

1. Go to your repository on GitHub

2. Click Actions tab

3. Click on the running "🚀 Deploy to Staging (Auto)" workflow

You'll see five jobs:

⚙️ Setup → 🔒 Security Scan → 🏗️ Build & Push → ⏸️ Wait for Approval → 🚀 Deploy to Staging

The first three jobs will complete in about 5-10 minutes.

Approve the Deployment (Issue-Based Method)

When the workflow reaches the "⏸️ Wait for Approval" job, it will create a GitHub Issue.

Here's what happens:

1. Approval job creates an issue titled "🚀 Deploy v20241215-143052-a7f3d2c to Staging?"

2. Issue includes deployment details:

   • Version tag

   • Docker image path

   • Branch and commit

   • Who triggered it

   • Pre-deployment checklist

To approve the deployment:

1. Click "Issues" tab in your repository

2. Find the deployment approval issue (should be at the top)

3. Comment on the issue with one of these:

   • /approve

   • approved

   • lgtm

4. Press Comment

The workflow continues immediately:

Within a few seconds of your approval comment:

1. Approval job completes ✅

2. Deploy job starts automatically

3. SSH to server

4. Runs deploy-staging.sh with new version

5. Waits for startup

6. Performs health checks

7. Shows success or failure

8. Issue automatically closes

If you want to deny the deployment:

Comment /deny or denied on the issue - the workflow will cancel.

If you don't respond:

After 6 hours, the workflow auto-cancels and the issue closes.

What Success Looks Like

In the workflow summary:

## 🎉 Deployment Complete
**Version:** `v20241215-143052-a7f3d2c`
**Status:** ✅ Success
**URL:** https://api.yourdomain.com

In your browser:

Visit https://api.yourdomain.com/admin - you should see your Strapi admin panel with the latest code!

What Failure Looks Like

If deployment fails:

## ❌ Deployment Failed
Check deployment logs on server

Troubleshooting steps:

# SSH to your server
ssh deploy@YOUR_STAGING_SERVER_IP

# Check deployment logs
tail -50 /opt/strapi-backend/deployment.log

# Check if containers are running
cd /opt/strapi-backend
docker compose -f docker-compose.stg.yml ps

# Check container logs
docker compose -f docker-compose.stg.yml logs --tail=50 strapi-backend

Common issues:

• Wrong container names in deploy-staging.sh

• Server not accessible via SSH

• Image not found in GHCR (check registry path)

• Health check timeout (server might be slow)

• Wrong approvers list (check APPROVERS env var matches your GitHub username)

Step 9: Test the Manual-Dispatch Workflow

Now let's test deploying from a feature branch using the manual workflow.

Create a Test Feature Branch

# On your local machine
git checkout -b feature/test-manual-deploy

# Make a small change
echo "# Manual Deploy Test" >> README.md

# Commit and push
git add README.md
git commit -m "Test manual deployment workflow"
git push -u origin feature/test-manual-deploy

Trigger the Manual Workflow

1. Go to GitHub → Actions tab

2. Click "🚀 Deploy to Staging (Manual)" (left sidebar)

3. Click "Run workflow" button (right side)

You'll see a form:

• Use workflow from: Select feature/test-manual-deploy

• Version tag: Leave blank (or enter custom like v2.0.0-test)

• Click "Run workflow"

Watch the Deployment

The workflow runs immediately (no approval needed):

1. Setup job converts names to lowercase

2. Security scan checks for vulnerabilities

3. Build job creates and pushes Docker image

4. Deploy job runs immediately (no waiting)

5. Health check verifies deployment

Timeline:

• Total: 7-10 minutes

• No approval delay

• Deploys directly from feature branch

Verify the Deployment

After success:

# On your server
tail -20 /opt/strapi-backend/deployment.log

# Should show deployment of your feature branch version
# Version will be something like: v20241215-150422-b8e4f1a

Check your site: Visit https://api.yourdomain.com/admin - your feature branch code is now running in staging!

When to Use Which Workflow

Now that you have both workflows working, here's how to choose:

Use Auto-Deploy (staging-deploy.yml) When:

✅ Working on a team:

• Multiple developers need approval before staging updates

• Want to prevent accidental deployments

• Need audit trail of who approved what

✅ Following standard DevOps practices:

• Merge to dev → Review → Approve → Deploy

• Clear separation between "code merged" and "code deployed"

• Safer for production-like environments

✅ Learning deployment workflows:

• Approval gates teach proper deployment discipline

• Forces you to review changes before they go live

• Good practice for when you move to production

Typical workflow:

1. Develop in feature branch

2. Create PR to dev

3. CI validates (Part 5a)

4. Merge after review

5. Auto-deploy triggers

6. Approve deployment

7. Staging updates

Use Manual-Dispatch (staging-deploy-manual.yml) When:

✅ Solo developer or tiny team:

• Trust each other completely

• Want speed over process

• Don't need approval gates

✅ Testing feature branches:

• Want to test feature/new-ui in staging before merging

• Need to demo unfinished work to stakeholders

• Testing multiple features simultaneously

✅ Emergency hotfixes:

• Bug in production needs immediate testing

• Can't wait for PR approval process

• Need to deploy from hotfix/critical-bug branch ASAP

✅ Flexible deployment control:

• Sometimes deploy dev, sometimes feature branches

• Want to choose exactly what gets deployed

• Need custom version tags for releases

Typical workflow:

1. Push feature code to any branch

2. Go to Actions → Run workflow

3. Select branch

4. Click run

5. Staging updates immediately

Can You Use Both?

Absolutely! Many teams keep both:

• Auto-deploy for regular dev → staging updates

• Manual for testing features and emergencies

They don't conflict - just different triggers deploying to the same environment.

Extending for Multiple Environments

Right now both workflows deploy to your staging environment. Here's how to extend them for production, UAT, or other environments:

Multi-Environment Strategy:

Option 1: Separate Workflows Per Environment

Create multiple workflow files:

• staging-deploy.yml → Deploys to staging

• uat-deploy.yml → Deploys to UAT environment

• production-deploy.yml → Deploys to production

Each workflow:

• Uses different GitHub Environment (staging, uat, production)

• Uses different secrets (STAGING_, UAT_, PRODUCTION_*)

• Different approval requirements (production might need 2 approvers)

• Different triggers (production might only deploy from main branch)

Option 2: Environment Selector in Manual Workflow

Extend the manual workflow to let you choose the environment:

on:
  workflow_dispatch:
    inputs:
      environment:
        description: 'Environment to deploy to'
        required: true
        type: choice
        options:
          - staging
          - uat
          - production
      version:
        description: 'Version tag'
        required: false
        type: string

Then in the workflow:

deploy:
  name: 🚀 Deploy to ${{ inputs.environment }}
  environment: ${{ inputs.environment }}
  steps:
    - name: 🚀 Deploy
      run: |
        # Use environment-specific secrets
        ssh -i ~/.ssh/deploy_key \
          ${{ secrets[format('{0}_USER', upper(inputs.environment))] }}@\
          ${{ secrets[format('{0}_HOST', upper(inputs.environment))] }}

This gives you:

• One workflow file

• Dropdown to select staging/uat/production

• Different secrets per environment

• Different approval rules per environment

When to Add Multiple Environments:

Start simple (what we have now):

• One staging environment

• Two deployment workflows

• Learn the patterns first

Add environments when:

• You have real users (need production)

• Client wants UAT for acceptance testing

• Compliance requires separate environments

Don't add environments until you need them. Every environment adds complexity, another server to maintain, another set of secrets, another approval process.

Rollback Procedures

Deployments sometimes fail. Here's how to handle it:

Automatic Rollback (Built Into deploy-staging.sh)

The deployment script automatically rolls back if:

• Image pull fails

• docker-compose up fails

• Health check fails after deployment

What happens:

1. Deployment script detects failure

2. Restores docker-compose backup

3. Restores database from pre-deployment backup

4. Restarts containers with previous version

5. Logs the rollback

You don't need to do anything - it happens automatically.

Manual Rollback (Using rollback-staging.sh)

The rollback-staging.sh script (created in Step 3.5) provides several rollback options for when you need to manually revert changes:

Option 1: Check Current Status First

# SSH to server
ssh deploy@YOUR_STAGING_SERVER_IP
cd /opt/strapi-backend

# Check what's deployed and available rollback versions
./deployment-scripts/rollback-staging.sh status

Expected output:

==========================================
CURRENT STATUS
==========================================

Current Version:
  v20241208-143000-def5678

Container Status:
NAME              IMAGE                                    STATUS
strapi-backend    ghcr.io/you/your-repo:v20241208...      Up
strapiDB          postgres:16-alpine                       Up

Recent Deployment History:
2024-12-08 12:00:15 | v20241208-120000-abc1234 | SUCCESS
2024-12-08 14:30:22 | v20241208-143000-def5678 | SUCCESS

Available Rollback Versions:
  v20241208-120000-abc1234
  v20241208-143000-def5678

Available Database Backups:
-rw-r--r-- 1 deploy deploy 4.2M Dec  8 14:30 predeployment_v20241208_143052.sql.gz
-rw-r--r-- 1 deploy deploy 4.1M Dec  8 12:00 predeployment_v20241208_120015.sql.gz

Option 2: Rollback Application Only (Recommended)

# Rollback to previous version automatically
./deployment-scripts/rollback-staging.sh app

# Or rollback to specific version
./deployment-scripts/rollback-staging.sh app v20241208-120000-abc1234

This rolls back just the application code, keeping your current database data intact.

Option 3: Rollback Database Only

# Restore database from specific backup
./deployment-scripts/rollback-staging.sh database predeployment_v20241208_143052.sql.gz

Use this when the app is fine but database migration went wrong.

Option 4: Full Rollback (App + Database)

# Rollback everything to last known good state
./deployment-scripts/rollback-staging.sh full

This reverts both application and database to the last successful deployment.

Option 5: Re-run Previous Workflow (Via GitHub)

1. Go to GitHub → Actions tab

2. Find the last successful deployment

3. Click "Re-run all jobs"

4. This redeploys the previous version

Option 6: Deploy Specific Version (Via GitHub)

1. Go to GitHub → Actions tab

2. Select "🚀 Deploy to Staging (Manual)"

3. Click "Run workflow"

4. Select the Tags tab (if you've created Git tags for releases)

   • Choose the specific tag you want to deploy (e.g., v2.0.0-rc1)

   • Or stay on Branches tab to build from a branch

5. Enter the version in the input field

6. Click "Run workflow"

💡 Best Practice: Create Git tags for your releases:

# Create a tag for your release
git tag -a v2.0.0-rc1 -m "Release v2.0.0-rc1"
git push origin v2.0.0-rc1

# Now you can select this tag in the GitHub workflow UI

Rollback Best Practices:

• Always check status first - ./deployment-scripts/rollback-staging.sh status shows current state

• Test rollback during setup - Not during an emergency

• Use app-only rollback when possible - Preserves database changes

• Create safety backups - Script does this automatically

• Keep deployment history - deployment-history.txt tracks all deployments

• Don't delete old Docker images in GHCR - You need them for rollbacks

• Document your rollback steps - For team members who need to help

What We've Accomplished

Let's recap what your complete CI/CD pipeline now includes:

From Part 5a (CI):

• ✅ Automated code quality checks (ESLint)

• ✅ Security vulnerability scanning

• ✅ Docker build verification

• ✅ Green checkmark on every commit

From Part 5b (CD):

• ✅ Automated Docker image building and pushing to GHCR

• ✅ Two deployment workflow options:

  • Auto-deploy with approval gates (safe for teams)

  • Manual-dispatch from any branch (flexible for testing)

• ✅ SSH-based deployment to DigitalOcean

• ✅ Automated health checks after deployment

• ✅ Automatic rollback on failure

• ✅ Pre-deployment database backups

• ✅ Complete deployment logging

The Complete Flow:

For Regular Development:

Push to feature → CI validates (2-5 min) → Green checkmark
↓
Merge to dev → Security scan → Build image → Push to GHCR
↓
Approve deployment → SSH to server → Run deploy script
↓
Health check → Success ✅ or Auto-rollback ❌

For Testing Features:

Push to feature branch → CI validates → Green checkmark
↓
Click "Run workflow" → Select branch → Deploy immediately
↓
Health check → Success ✅ or Auto-rollback ❌

And you're still at $6/month for your DigitalOcean infrastructure. The CI/CD pipeline uses GitHub's free tier.

Congratulations! 🎉

You've built a complete, professional CI/CD pipeline for your Strapi v5 backend.
So yeah, that's the core setup. We've built a complete deployment pipeline for $6/month (plus a few cents for S3 backups).

If there's enough interest, I might write a follow-up about the real-world performance of this setup, actual costs after running it for months, uptime stats, what breaks when you push this budget setup to its limits, and when you know it's time to upgrade.

For now though, you've got everything you need to deploy, iterate, and scale. The foundation is solid.

What started as a $6/month staging experiment is now a fully automated deployment system with:

• Continuous integration validating every commit

• Automated Docker image builds

• Two deployment workflow options

• Health checks and automatic rollback

• Complete logging and monitoring

More importantly, you understand:

• How Docker containerization works

• How CI/CD pipelines are built

• How to deploy with GitHub Actions

• How to maintain and troubleshoot deployments

• When to upgrade and when not to

This knowledge transfers to any platform - AWS, GCP, Azure, or whatever comes next.

Thanks for following along through all five parts. Happy deploying! 🚀

Series Navigation:

• Part 0: Introduction - Why This Setup?

• Part 1: Containerizing Strapi v5

• Part 2: Deploying to DigitalOcean

• Part 3: Production Web Server Setup

• Part 4: Automated Database Backups

• Part 5a: CI Pipeline with GitHub Actions (You are here)

• Part 5b: CD Pipeline and Deployment Automation (Coming next week)

New to the series? Each article works standalone, but if you want to follow along with actual deployments, start with Parts 1-4.

Alright, we've built a solid infrastructure - containerized Strapi, DigitalOcean deployment, Nginx with SSL, and automated backups. But here's the problem: every time you want to deploy new code, you're manually building Docker images, pushing them to GitHub Container Registry, SSHing into your server, pulling the new image, and restarting containers.

That works fine when you're deploying once a week. But as your project grows? You'll be deploying daily, maybe multiple times a day. Manual deployments become a bottleneck fast.

This is where CI/CD comes in. In this article (Part 5a), we're building the CI (Continuous Integration) part - automated validation and build verification every time you push code. We'll create a GitHub Actions workflow that:

• Automatically validates your code when you push to any feature or fix branch

• Runs security scans to catch vulnerabilities early

• Checks code quality (ESLint if you have it configured)

• Verifies your Docker image builds successfully

• Gives you that green checkmark (or red X) on every commit

In Part 5b, we'll add the CD (Continuous Deployment) part - actually deploying those validated builds to your DigitalOcean server with proper approval gates and rollback capabilities.

Why split this into two articles? I originally planned to cover CI/CD in one go, but that would've been a 30-40 minute read. Nobody wants to sit through that. Breaking it into two parts makes it digestible and lets you test the CI pipeline before adding deployment complexity.

Let's build this thing.

What Is CI/CD Anyway?

If you're new to these terms, here's the quick version:

CI (Continuous Integration):

• Automatically validate and test your code when you push changes

• Catch bugs early, before they reach production

• Make sure your code actually compiles and passes basic checks

• Create a culture where "broken builds" get fixed immediately

CD (Continuous Deployment/Delivery):

• Automatically deploy those validated builds to your servers

• Add approval gates so you control when things go live

• Provide rollback mechanisms when things break

• Make deployments boring and predictable

The philosophy:

• Small, frequent changes are safer than big, scary deployments

• Automate the boring, error-prone stuff (validating, testing, deploying)

• Spend your time building features, not babysitting deployments

For our staging environment, we're building a system that's professional without being overkill. You won't need a full-time DevOps team to maintain this.

Understanding the Green Checkmark (For Beginners)

If you've used GitHub before, you've probably seen green checkmarks and red X marks next to commits. Here's what they actually mean:

The Green Checkmark (✅):

• Your code passed all automated checks

• It compiles, builds, and doesn't have obvious issues

• Safe to review and potentially merge

The Red X (❌):

• Something failed - maybe security issues, build errors, or test failures

• Don't merge this yet - fix the problems first

• Click on it to see what went wrong

Why this matters:

Before CI, you'd push code and only discover it broke things when someone tried to deploy or run it. With CI, you know immediately if your changes broke something. The faster you catch issues, the easier they are to fix.

In practice:

• Push a feature branch → See green checkmark → Create pull request with confidence

• Push a feature branch → See red X → Fix issues before anyone reviews

• Review a pull request → See green checkmark → Know the code at least compiles

This workflow makes code reviews way more productive because you're discussing the actual logic, not debugging basic build failures.

What We're Building in Part 5a

By the end of this article, you'll have a CI pipeline that runs on every push to:

• main branch

• dev branch

• feature/** branches

• fix/** branches

• Any pull requests targeting main or dev

What the pipeline does:

1. Code Quality Check:

• Runs ESLint if you have it configured

• Skips gracefully if you don't (workflow works for everyone)

• Helps catch common code issues early

2. Security Audit:

• Runs npm audit to check for vulnerable dependencies

• Reports high and moderate severity issues

• Doesn't fail the build (just warns you to fix them)

3. Build Verification:

• Attempts to build your Docker image

• Uses caching to make builds faster (2-5 minutes)

• Proves your code can compile into a deployable image

• Does NOT push to GHCR (we'll explain why in a moment)

4. Clear Summary:

• Shows all check results in one place

• Makes it obvious what passed or failed

• Provides context (branch, commit) for debugging

The Result: Push any code → Wait 5-7 minutes → See green checkmark or red X → Know if your code is deployment-ready

Why We're NOT Pushing to GHCR in CI

You might wonder: "Why build the image but not push it to GitHub Container Registry?"

Here's the problem with pushing every build:

The Issue:

• You push 20 feature branches while working on different ideas

• Each push creates a new image in GHCR

• GHCR has storage limits (500MB free tier, 2GB on Pro)

• Your registry fills up with images you'll never use

• Cleaning them up manually is a pain

Our Approach:

• CI just verifies the image can build successfully

• The actual image gets discarded after verification

• Only deployments (Part 5b) push to GHCR

• This keeps your registry clean and organized

If you really want every build in GHCR:

You can modify the workflow to push on specific branches. We'll mention how to do this later. But for most developers working on multiple features, the build-only approach is cleaner.

The CD workflow in Part 5b will build and push to GHCR only when you're actually deploying to staging.

Prerequisites

Before we start, make sure you have:

• Parts 1-4 completed (containerized Strapi with working deployment)

• Code in a GitHub repository (public or private)

• Dockerfile.stg in your project root (from Part 1)

• Dev branch created (or working directly on main)

• About 45-60 minutes

If you're working on multiple features, I recommend creating a dev branch for active development and keeping main for production-ready code.

Step 1: Understanding GitHub Actions Basics

Before we write the workflow, let's quickly cover how GitHub Actions actually works.

The Basics

Workflow:

• A YAML file in .github/workflows/ directory

• Defines when to run (on push, pull request, schedule, etc.)

• Contains one or more jobs

Job:

• A collection of steps that run together

• Runs on a virtual machine (runner)

• Can depend on other jobs

Step:

• Individual task within a job

• Can run shell commands or use pre-built actions

• Has access to your repository code

Runner:

• Virtual machine that executes your workflow

• GitHub provides free runners (Ubuntu, Windows, macOS)

• For public repos: unlimited minutes

• For private repos: 2,000 free minutes/month (plenty for us)

Why GitHub Actions?

You might wonder why we're using GitHub Actions instead of Jenkins, CircleCI, or GitLab CI:

Reasons it works for us:

• Built into GitHub (no external service to set up)

• Free for public repos, generous free tier for private

• Great Docker support out of the box

• Easy to test and debug

• Popular (lots of community actions and examples)

For a staging environment? GitHub Actions is perfect.

Step 2: Create the CI Workflow

Now let's create the GitHub Actions workflow file.

Create Workflow Directory

# In your project root
mkdir -p .github/workflows

Create the CI Workflow File

# Create the workflow file
nano .github/workflows/ci.yml

Paste this complete workflow:

Understanding the Workflow Structure

Let's break down what this workflow actually does:

Workflow Triggers

on:
  push:
    branches:
      - main
      - dev
      - 'feature/**'
      - 'fix/**'
  pull_request:
    branches:
      - main
      - dev

What this means:

• Runs on every push to main, dev, feature/*, and fix/* branches

• Runs on pull requests targeting main or dev

• The 'feature/**' pattern matches feature/user-auth, feature/payment-system, etc.

• The 'fix/**' pattern matches fix/login-bug, fix/memory-leak, etc.

Adding more branch patterns:

If your team uses other naming conventions (like hotfix/**, bugfix/**, chore/**), just add them to the list:

branches:
  - main
  - dev
  - 'feature/**'
  - 'fix/**'
  - 'hotfix/**'    # Add this if you use hotfix branches
  - 'bugfix/**'    # Add this if you use bugfix branches

The workflow is flexible, adjust it to match your team's branching strategy.

Job 1: Code Quality (ESLint)

lint:
  name: 🔍 Code Quality
  runs-on: ubuntu-latest

This job checks your code quality using ESLint.

The smart part:

if [ -f ".eslintrc.js" ] || [ -f ".eslintrc.json" ] || [ -f "eslint.config.js" ]; then
  echo "ESLint config found, running linter..."
  npm run lint || echo "⚠️  No lint script found in package.json"
else
  echo "ℹ️  No ESLint config found, skipping..."
fi

The workflow checks if you have ESLint configured. If you do, it runs, if you don't, it skips gracefully. This means the workflow works for everyone regardless of their linting setup.

Job 2: Security Audit

security:
  name: 🔒 Security Audit
  runs-on: ubuntu-latest

This job scans your dependencies for known security vulnerabilities.

The audit process:

npm audit --audit-level=moderate

This checks all your npm packages against a vulnerability database and reports issues rated "moderate" severity or higher.

Understanding continue-on-error: true:

continue-on-error: true

We don't fail the entire build if vulnerabilities are found. Instead, we report them so you can fix them. Here's why:

Practical reality:

• Many vulnerabilities are low-risk for backend APIs

• Some "vulnerabilities" only affect browser environments (not relevant for Strapi)

• Blocking every build for minor issues would slow you down too much

What we do instead:

• Report all vulnerabilities clearly

• Count high vs moderate severity issues

• Let you decide urgency based on context

• Encourage fixes without blocking development

The detailed report:

HIGH=$(cat audit-report.json | grep -o '"severity":"high"' | wc -l || echo "0")
MODERATE=$(cat audit-report.json | grep -o '"severity":"moderate"' | wc -l || echo "0")

echo "- **High**: $HIGH" >> $GITHUB_STEP_SUMMARY
echo "- **Moderate**: $MODERATE" >> $GITHUB_STEP_SUMMARY

You get a clear count of vulnerabilities in the workflow summary. If you see high-severity issues, you should probably fix them before deploying.

Job 3: Build Verification

build:
  name: 🏗️ Build Verification
  runs-on: ubuntu-latest
  needs: [lint, security]

This job verifies your Docker image builds successfully. The needs: [lint, security] means it only runs if both previous jobs pass.

The build step:

- name: 🐳 Build Docker image (test only)
  uses: docker/build-push-action@v6
  with:
    context: .
    file: ./Dockerfile.stg
    push: false
    tags: test-build:latest
    platforms: linux/amd64
    cache-from: type=gha
    cache-to: type=gha,mode=max

Key settings:

• push: false - This is critical. We build the image but don't push it anywhere

• tags: test-build:latest - Just a local tag, not used outside this workflow

• platforms: linux/amd64 - Builds for DigitalOcean's architecture

• cache-from/cache-to: type=gha - Uses GitHub Actions cache for faster builds

Why not push to GHCR?

As mentioned earlier, pushing every feature branch to GHCR clutters your registry. This approach:

• ✅ Verifies your code compiles into a valid Docker image

• ✅ Uses caching to keep builds fast (2-5 minutes)

• ✅ Keeps your registry clean

• ✅ Saves bandwidth and storage

The CD workflow (Part 5b) will build and push to GHCR only when actually deploying.

If you want to push certain branches:

Add this condition to enable pushing for specific branches:

- name: 🐳 Build and push Docker image
  uses: docker/build-push-action@v6
  with:
    context: .
    file: ./Dockerfile.stg
    push: ${{ github.ref == 'refs/heads/dev' }}  # Only push dev branch
    tags: ghcr.io/${{ github.repository }}:${{ github.ref_name }}
    platforms: linux/amd64
    cache-from: type=gha
    cache-to: type=gha,mode=max

This would push only the dev branch to GHCR. But for most use cases, the build-only approach is cleaner.

Job 4: Summary Jobs

ci-success:
  name: ✅ CI Complete
  needs: [lint, security, build]
  if: success()

These jobs provide clear feedback about the overall CI status.

Success job:

• Runs only if all previous jobs passed

• Creates a nice summary with green checkmarks

• Shows branch and commit information

• Confirms the code is safe to deploy

Failure job:

ci-failure:
  name: ❌ CI Failed
  needs: [lint, security, build]
  if: failure()

• Runs only if any previous job failed

• Creates a summary explaining what went wrong

• Makes it obvious the code needs fixes

• Exits with error code to mark the workflow as failed

Why these summary jobs matter:

When you look at your commits on GitHub, you see:

• Green checkmark → All CI checks passed

• Red X → Something failed (click to see what)

These summary jobs make that status immediately clear without digging through logs.

Step 3: Commit and Push the Workflow

Now let's activate the workflow:

# Make sure you're on dev branch
git checkout dev

# Add the workflow file
git add .github/workflows/ci.yml

# Commit
git commit -m "Add CI pipeline with security scanning and build verification"

# Push to dev branch
git push origin dev

What happens next:

1. GitHub receives your push

2. Detects the workflow file

3. Starts running the CI pipeline

4. You can watch it live in GitHub Actions tab

Important Note About Workflow Visibility:

Your CI workflow will automatically run as soon as you push it because of the push trigger we configured. Once it runs for the first time, you'll see it appear in the Actions tab on GitHub.

Note: If you were creating a workflow_dispatch (manually triggered) workflow instead, you'd need to merge it to the default branch first for the "Run workflow" button to appear. But since our CI workflow triggers automatically on push/pull_request events, you don't need to worry about this - it'll just work immediately.

Step 4: Monitor Your First Build

Let's watch the pipeline run for the first time.

View the Workflow Run

1. Go to your GitHub repository

2. Click on "Actions" tab

3. You should see "🔄 Continuous Integration" running

What You'll See

The workflow page shows:

• Overall status (queued, running, success, failed)

• Individual job status (lint, security, build, summary)

• Real-time logs

• Time taken for each step

Click on the workflow run to see detailed logs.

Job Progress

Job 1 - Code Quality (~1-2 minutes):

📥 Checkout code
🔧 Setup Node.js
📦 Install dependencies
🔍 Run ESLint (if configured)
📊 Lint summary

If you don't have ESLint configured, you'll see:

ℹ️  No ESLint config found, skipping...

That's perfectly fine - the job still passes.

Job 2 - Security Audit (~2-3 minutes):

📥 Checkout code
🔧 Setup Node.js
📦 Install dependencies
🔍 Run security audit
📊 Generate detailed report

If you have no vulnerabilities:

✅ No security vulnerabilities found!

If you have some:

⚠️  Security vulnerabilities detected - check details above
- High: 0
- Moderate: 3

Job 3 - Build Verification (~5-10 minutes first time):

📥 Checkout code
🛠️ Set up Docker Buildx
🐳 Build Docker image (test only)
✅ Build successful

The first build takes longer because there's no cache. Subsequent builds use cached layers and finish in 2-5 minutes.

Job 4 - Summary:

🎉 All checks passed

✅ Continuous Integration Passed!

All validation checks completed successfully:
- ✅ Code quality check
- ✅ Security audit
- ✅ Build verification

Branch: dev
Commit: abc1234...
This code is safe to deploy! 🚀

Understanding Build Times

First build: 10-15 minutes total

• Code quality: 2 minutes

• Security audit: 3 minutes

• Build verification: 8 minutes (no cache)

• Summary: instant

Subsequent builds: 5-7 minutes total

• Code quality: 2 minutes

• Security audit: 2 minutes (dependency cache)

• Build verification: 2-3 minutes (Docker cache)

• Summary: instant

The workflow gets faster as caches build up.

Step 5: Testing the CI Pipeline

Let's create a feature branch and watch CI in action.

Create a Feature Branch

# Create a new feature branch
git checkout -b feature/test-ci

# Make a small change
echo "# CI Pipeline Active" >> README.md

# Commit and push
git add README.md
git commit -m "Add CI status to README"
git push -u origin feature/test-ci

Watch the Green Checkmark Appear

1. Go to your repository on GitHub

2. Click on "Commits" or look at your branch

3. You'll see a yellow circle while CI runs

4. After 5-10 minutes, it becomes:

   • Green checkmark (✅) if all checks passed

   • Red X (❌) if something failed

Click on the checkmark/X to see detailed results without leaving the commits page.

Create a Pull Request

# Go to GitHub UI
# Click "Compare & pull request" for your feature branch
# Create the PR

On the PR page, you'll see:

✅ All checks have passed
3 successful checks

Or if something failed:

❌ Some checks were not successful
1 failing check

This makes code review way easier, reviewers know the code at least compiles before they start reviewing logic.

Step 6: Understanding Check Details

Let's look at what each check tells you.

Code Quality Results

If you have ESLint configured and it finds issues:

Line 45:  'userName' is assigned a value but never used  no-unused-vars
Line 102: Expected '===' but got '=='                    eqeqeq

Fix these before merging. Clean code = fewer bugs.

Security Audit Results

If vulnerabilities are found:

## 🔒 Security Audit Results
⚠️  Security vulnerabilities detected

### Vulnerability Details:
- High: 2
- Moderate: 5

found 7 vulnerabilities (5 moderate, 2 high) in 234 scanned packages

What to do:

# Try automatic fixes first
npm audit fix

# If that doesn't work, update specific packages
npm update package-name

# Commit the fixes
git add package.json package-lock.json
git commit -m "Fix security vulnerabilities"
git push

CI will run again with the fixed dependencies.

Build Verification Results

If the build fails:

❌ Build Verification Failed

ERROR: failed to solve: failed to read dockerfile: open Dockerfile.stg: no such file

Common build failures:

1. Dockerfile not found - Check filename and location

2. npm install fails - Check package.json syntax

3. Build fails - Check TypeScript/build errors

4. Out of memory - Simplify build or use multi-stage better

The logs show exactly where the build failed, making it easy to fix.

Extending the Workflow

The workflow we built covers the essentials: code quality, security, and build verification. But you can add much more depending on your needs.

Common Additions

1. Unit Tests

If you have tests in your Strapi project:

test:
  name: 🧪 Run Tests
  runs-on: ubuntu-latest
  needs: lint

  steps:
    - name: Checkout code
      uses: actions/checkout@v4

    - name: Setup Node.js
      uses: actions/setup-node@v4
      with:
        node-version: ${{ env.NODE_VERSION }}
        cache: 'npm'

    - name: Install dependencies
      run: npm ci

    - name: Run tests
      run: npm test

Then update the build job to depend on tests:

build:
  needs: [lint, security, test]

2. Code Coverage

Track how much of your code is tested:

- name: Generate coverage report
  run: npm run test:coverage

- name: Upload coverage to Codecov
  uses: codecov/codecov-action@v3
  with:
    file: ./coverage/coverage-final.json

3. TypeScript Type Checking

If using TypeScript:

- name: Type check
  run: npm run type-check

4. Format Checking (Prettier)

Enforce consistent code formatting:

- name: Check formatting
  run: npx prettier --check "src/**/*.{js,ts,json}"

5. Dependency Review

Check for license issues or outdated dependencies:

- name: Check outdated dependencies
  run: npm outdated || true

6. Performance Budgets

Ensure bundle sizes don't grow too large:

- name: Check bundle size
  run: npm run build && du -sh build/

When to Add More Checks

Start simple (what we have now):

• Code quality (ESLint)

• Security audit

• Build verification

Add as needed:

• Unit tests when you write tests

• Code coverage when tests are comprehensive

• Type checking if using TypeScript

• Format checking if team has formatting wars

Don't add everything at once. Start with basics, add more as your project and team grow.

Common Issues and Fixes

Here are problems you might encounter:

Issue: Workflow doesn't trigger

Symptom: You push code but no workflow runs

Diagnosis:

# Check you're on a tracked branch
git branch --show-current

# Verify workflow file exists
ls -la .github/workflows/ci.yml

# Check if it's committed
git log --oneline | head -5

Solution:

# Make sure workflow is committed
git add .github/workflows/ci.yml
git commit -m "Add CI workflow"
git push

# Check GitHub Actions tab for any error messages

Issue: Security audit reports vulnerabilities

Symptom: Job shows warnings about vulnerable packages

Solution:

# Attempt automatic fixes
npm audit fix

# If fixes aren't available
npm audit fix --force  # May update to newer major versions

# Or update specific packages
npm update package-name

# Verify fixes
npm audit

# Commit changes
git add package.json package-lock.json
git commit -m "Fix security vulnerabilities"
git push

When to ignore:

Some vulnerabilities are safe to ignore:

• Development-only dependencies (testing tools, etc.)

• Vulnerabilities that don't affect server-side code

• False positives

Use your judgment, but don't ignore critical/high severity issues in production dependencies.

Issue: ESLint job fails even with no config

Symptom: The lint job fails despite having continue-on-error: true

Solution:

This shouldn't happen, but if it does:

# Add a basic .eslintrc.json
cat > .eslintrc.json << 'EOF'
{
  "extends": ["eslint:recommended"],
  "env": {
    "node": true,
    "es2021": true
  },
  "parserOptions": {
    "ecmaVersion": 12
  }
}
EOF

# Add lint script to package.json
# "scripts": {
#   "lint": "eslint ."
# }

# Commit
git add .eslintrc.json package.json
git commit -m "Add ESLint configuration"
git push

Issue: Build is extremely slow (>20 minutes)

Diagnosis:

Check if caching is working:

# Look in workflow logs for:
# "Cache restored from key: ..."

Solution:

If cache isn't working, verify these settings in your workflow:

cache-from: type=gha
cache-to: type=gha,mode=max

Also check:

• First build is always slow (10-15 minutes)

• Subsequent builds should be 2-5 minutes

• If consistently slow, your Dockerfile might not be optimized for caching

Optimize Dockerfile for caching:

# Good - dependencies cached separately
COPY package.json package-lock.json ./
RUN npm ci
COPY . .

# Bad - everything rebuilds on any change
COPY . .
RUN npm ci

Issue: Jobs run out of order

Symptom: Build job starts before security job finishes

Solution:

This shouldn't happen with the needs: directive, but if it does:

# Make sure build job has this:
build:
  needs: [lint, security]  # Waits for both jobs

Issue: Pull request shows "Some checks haven't completed yet" forever

Symptom: PR shows pending checks that never finish

Solution:

Usually a workflow configuration issue:

# Check Actions tab for stuck workflows
# Cancel any stuck runs manually
# Push a new commit to retrigger

If this happens repeatedly, there might be a syntax error in your workflow file. GitHub's workflow validator will show errors in the Actions tab.

Understanding GitHub Actions Costs

Let's talk about what this actually costs you.

For Public Repositories:

Completely free. Unlimited minutes. No cost whatsoever.

For Private Repositories:

Free tier:

• 2,000 minutes/month

• Shared across all private repos

• Resets monthly

Our typical usage:

• Code quality: ~2 minutes

• Security audit: ~2 minutes

• Build verification: ~3 minutes (with cache)

• Summary: instant

• Total per run: ~7 minutes

Monthly estimate:

• 10 feature branches × 3 pushes each × 7 minutes = 210 minutes

• 20 PR commits × 7 minutes = 140 minutes

• Total: ~350 minutes/month

You'd need 285+ CI runs per month to exceed the free tier. That's roughly 10 runs per day. If you're pushing that often, you might need to limit the CI workflow to important branches only (like main and dev), or you'll have to pay for the extra minutes.

If You Exceed Free Tier:

GitHub charges $0.008 per minute for private repos.

• 3,000 minutes/month = $8/month extra

• That's still cheaper than most CI services

For a staging environment working on 2-5 features simultaneously, you'll stay well within the free tier.

What We've Accomplished

Let's recap what your CI pipeline now does:

Automated Validation:

• ✅ Runs on every push to main, dev, feature, and fix branches

• ✅ Checks code quality with ESLint (if configured)

• ✅ Scans for security vulnerabilities

• ✅ Verifies Docker image builds successfully

• ✅ Provides clear pass/fail status on every commit

Developer Experience:

• ✅ See green checkmark or red X immediately

• ✅ Catch issues before code review

• ✅ Know code compiles before merging

• ✅ Get detailed feedback on what's wrong

Clean Registry Management:

• ✅ Builds verify code works

• ✅ Doesn't clutter GHCR with test images

• ✅ Keeps storage costs minimal

• ✅ CD workflow (Part 5b) handles actual deployments

Professional Workflow:

• ✅ Industry-standard CI practices

• ✅ Works for solo developers and teams

• ✅ Extensible for your specific needs

• ✅ Free for public repos, affordable for private

And you're still at $6/month for your DigitalOcean infrastructure. The CI pipeline is free (or nearly free for private repos).

What's Missing (Coming in Part 5b)

Right now, you have automatic validation but still deploy manually:

1. Merge PR to dev

2. SSH into server

3. Pull new image (wait, we're not pushing images yet!)

4. Rebuild and restart

5. Hope nothing breaks

Part 5b will add:

• Automated Docker image building and pushing to GHCR (only when deploying)

• Automated deployment to your DigitalOcean server

• Manual approval gates (you control when deployments happen)

• Health checks (verify deployment succeeded)

• Automatic rollbacks (revert if deployment fails)

• Deployment scripts (single command to deploy or rollback)

• Complete CD pipeline from approved merge to running server

The CI part we built today is the foundation - it ensures your code is valid and buildable. Part 5b completes the pipeline by actually deploying that validated code.

A Note on the Deployment Step

You might have noticed we validate code but don't push images to GHCR. Here's why we're saving that for Part 5b:

The Philosophy:

CI should answer: "Is this code good?"

• Does it compile? ✅

• Are there security issues? ⚠️

• Does it pass quality checks? ✅

CD should answer: "Let's deploy this code."

• Build production image

• Push to registry

• Deploy to server

• Verify it works

Separating concerns:

• CI runs on every branch (frequent, lightweight)

• CD runs on approved merges (infrequent, intentional)

• This keeps your registry clean and deploys deliberate

In Part 5b, we'll build and push to GHCR as part of the deployment workflow, not the validation workflow.

Quick Reference

Workflow File Location:

.github/workflows/ci.yml

Branches That Trigger CI:

• main

• dev

• feature/** (all feature branches)

• fix/** (all fix branches)

• Pull requests to main or dev

Add More Branch Patterns:

on:
  push:
    branches:
      - main
      - dev
      - 'feature/**'
      - 'fix/**'
      - 'hotfix/**'     # Add this
      - 'release/**'    # Or this

View Workflow Runs:

1. Repository → Actions tab

2. Click on workflow run

3. Click on job name

4. Expand steps to see details

Trigger Workflow Manually:

1. Actions tab

2. Select "🔄 Continuous Integration"

3. Click "Run workflow"

4. Choose branch

5. Click "Run workflow"

What's Next: Part 5b Preview

In the next (and final!) article of this series, we're completing the automation:

What Part 5b Will Cover:

Deployment Automation:

• Setting up GitHub Environments (staging environment config)

• Adding SSH deployment keys securely

• Creating deployment scripts on your server

• Building the CD workflow with image push to GHCR

• Implementing manual approval gates

• Adding health checks and monitoring

• Creating rollback procedures

• Testing the complete end-to-end pipeline

The Final Result:

After completing Part 5b, you'll have TWO deployment workflow options:

Option 1 - Auto-Deploy on Merge (Recommended for most teams):

1. Push feature code → CI validates (green checkmark)

2. Create PR → CI runs again on PR

3. Merge to dev → CD workflow triggers automatically

4. Click "Approve Deployment" in GitHub

5. Automatic build → Push to GHCR → Deploy to staging

6. Health check confirms deployment worked

7. If something breaks → One-click rollback

Option 2 - Manual-Dispatch Workflow (Great for small teams & testing):

1. Push your code to ANY branch → CI validates

2. Go to Actions tab → Click "Run workflow"

3. Select which branch to deploy from (dev, feature, hotfix, etc.)

4. Enter version (or auto-generate)

5. Deployment runs immediately (no approval needed)

Why small teams love this:

• Deploy from any branch without merging first (perfect for testing)

• No approval gates needed (you're already being intentional by clicking "Run")

• Great for solo developers or tight-knit teams

• Test feature branches in your dev environment before merging to staging/main

• Emergency hotfixes when you need speed

Most larger teams use Option 1 for regular development (safety with approval gates), while smaller teams often prefer Option 2 for its flexibility. Many teams keep both - Option 1 for normal workflow, Option 2 for testing and emergencies.

You'll go from manual deployments to a professional CI/CD pipeline with full control, safety nets, and automatic validation at every step.

Got questions about the CI setup or running into issues with the workflow? Drop a comment and I'll help troubleshoot. Next week, we're wrapping up the series with the CD pipeline and deployment automation - the final piece that completes the puzzle!

Series Navigation:

• Part 0: Introduction - Why This Setup?

• Part 1: Containerizing Strapi v5

• Part 2: Deploying to DigitalOcean

• Part 3: Production Web Server Setup

• Part 4: Automated Database Backups (You are here)

• Part 5: CI/CD Pipeline with GitHub Actions (Coming next week)

New to the series? Each article works standalone, but if you haven't set up your DigitalOcean deployment yet, start with Parts 1-3.

Your Strapi backend is running smoothly, you've got HTTPS working, and everything looks professional. But there's one critical piece missing: what happens when something goes wrong?

Database corruption, accidental deletions, botched deployments, server failures, these scenarios happen more often than you'd think. Without proper backups, you're looking at hours of manual recovery work or potentially losing data entirely.

In this article, we're setting up automated daily backups to AWS S3. The entire system costs about $0.001/month (less than a penny) for a small database, and provides a reliable backup strategy that's appropriate for staging environments and early-stage production. If you need more frequent backups, you can easily adjust the schedule to run every few hours or even hourly without changing the core setup.

Let's build the safety net.

Why Bother with Backups?

You might be thinking, "It's just a staging environment, do I really need backups?"

Here's what can go wrong without them:

• Deploy a bad migration that corrupts your data

• Accidentally drop the wrong table while testing

• Server crashes and Docker volume gets corrupted

• Need to test a restore procedure (you DO test your restores, right?)

• Want to roll back to yesterday's data after finding a bug

Without backups, you're rebuilding everything from scratch. With backups, you're back online in 5 minutes.

Plus, setting this up now means you understand backup procedures before moving to production. Trust me, you don't want to learn this stuff during an actual emergency.

What We're Building

Here's what the complete backup system includes:

Automated Daily Backups:

• Runs automatically at 2:00 AM every day via cron

• Creates PostgreSQL database dump

• Compresses the backup (typically 80-90% size reduction)

• Uploads to AWS S3 with intelligent storage classes

• Verifies backup integrity

• Cleans up old local backups (7-day retention)

Smart Storage Management:

• First 30 days: S3 Standard-IA (Infrequent Access)

• After 30 days: Automatically moves to Glacier

• After 120 days: Automatically deletes

• Keeps 7 days of local backups for quick restores

Reliable Restore Process:

• Can restore from either local or S3 backups

• Handles database constraints properly (this was tricky to get right)

• Creates safety backup before restoring

• Verifies restoration worked

The Cost: For a typical small Strapi database (5-50MB):

• Storage: ~$0.0005/month

• Requests: ~$0.0005/month

• Total: About $0.001/month (one-tenth of a penny)

Even if your database grows to 1GB, you're still under $0.10/month. This is essentially free disaster recovery.

Prerequisites

Before we start, make sure you have:

• Parts 1-3 completed (Strapi running on DigitalOcean with PostgreSQL)

• AWS account (free tier covers this easily)

• SSH access to your droplet

• Basic terminal skills

• About 60-90 minutes for complete setup and testing

Don't have an AWS account yet? You'll need one for this. AWS offers a free tier that covers way more than what we'll use. Sign up at aws.amazon.com

Understanding the Backup Strategy

Before diving into setup, let's talk about what makes a good backup strategy.

The 3-2-1 Rule

The gold standard in backups is the 3-2-1 rule:

• 3 copies of your data (original + 2 backups)

• 2 different storage types (local disk + cloud)

• 1 offsite copy (S3 in a different location than your droplet)

That's exactly what we're building here.

Why S3 Storage Classes Matter

AWS S3 has different storage tiers with different costs:

S3 Standard ($0.023/GB/month):

• For frequently accessed data

• Instant retrieval

• Most expensive

S3 Standard-IA ($0.0125/GB/month):

• For infrequent access (perfect for backups)

• Instant retrieval

• ~50% cheaper than Standard

S3 Glacier ($0.004/GB/month):

• For archival storage

• Takes 1-5 minutes to retrieve

• ~80% cheaper than Standard

Our Strategy:

• Store new backups in Standard-IA (instant access if needed)

• After 30 days, move to Glacier (cheaper, rarely need old backups instantly)

• After 120 days, delete (4 months of history is plenty for staging)

This gives you quick access to recent backups while keeping costs minimal for older ones.

Why 30 days before Glacier? S3 charges a minimum 30-day storage fee. Moving to Glacier earlier actually costs more due to early deletion fees.

Step 1: AWS Account Setup

Let's get your AWS account configured properly.

Create IAM Policy First

Before creating the user, we need to create a custom policy that defines exactly what permissions our backup user will have.

Steps:

1. AWS Console → IAM → Policies → Create Policy

2. Switch to JSON tab and paste this policy:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "s3:ListAllMyBuckets"
            ],
            "Resource": "*"
        },
        {
            "Effect": "Allow",
            "Action": [
                "s3:GetObject",
                "s3:PutObject",
                "s3:DeleteObject",
                "s3:ListBucket",
                "s3:PutObjectAcl",
                "s3:GetBucketLocation",
                "s3:PutLifecycleConfiguration",
                "s3:GetLifecycleConfiguration"
            ],
            "Resource": [
                "arn:aws:s3:::your-backup-bucket-*",
                "arn:aws:s3:::your-backup-bucket-*/*"
            ]
        }
    ]
}

3. Click "Next"

4. Policy name: StrapiBackupPolicy

5. Description: "Allows backup operations to S3 buckets with lifecycle management"

6. Click "Create policy"

Important: Notice the PutLifecycleConfiguration and GetLifecycleConfiguration permissions. These are needed for the lifecycle policy we'll set up later. Missing these permissions is a common gotcha.

Create IAM User

Now let's create the user and attach our policy.

Steps:

1. AWS Console → IAM → Users → Create User

2. User details:

   • Username: strapi-backup-user

   • Check: "Provide user access to the AWS Management Console" - UNCHECK THIS

   • We only need programmatic access (API keys), not console access

3. Set permissions:

   • Select: "Attach policies directly"

   • Search for: StrapiBackupPolicy

   • Check the box next to your policy

4. Review and create user

5. Create access key:

   • After user creation, click on the user

   • Go to "Security credentials" tab

   • Click "Create access key"

   • Choose: "Command Line Interface (CLI)"

   • Check the confirmation box

   • Click "Create access key"

6. Save the credentials!

   • Access Key ID

   • Secret Access Key

Copy these somewhere safe. You won't see the secret key again.

Don't commit these keys to Git. Don't paste them in Slack. Don't email them. These are like passwords.

Why this approach?

We're attaching the policy directly to the user rather than creating a group. For a single backup user in a staging environment, this is simpler and perfectly appropriate. If you're setting up multiple users with similar permissions, AWS recommends using groups, but that's overkill for our use case.

Step 2: Create S3 Bucket

Now let's create the actual storage bucket for our backups.

Create the Bucket

1. S3 → Create bucket

2. Bucket settings:

Name: your-app-backups-staging-YYYYMMDD
Region: Choose one close to your users

About bucket names: They must be globally unique across all AWS accounts. That's why I suggest adding a date - strapi-backups-20251208 will probably be available even if strapi-backups isn't.

About regions: Pick a region close to your users (or your DigitalOcean droplet). This reduces latency and costs for data transfer. If you're in Europe, use eu-west-1. In US, use us-east-1 or us-west-2. In Asia, use ap-south-1 or ap-southeast-1.

3. Object Ownership:

   • Select: ACLs disabled (recommended)

   • Bucket owner enforced

4. Block Public Access:

   • Enable all four checkboxes ✅

   • We definitely don't want public backups

5. Versioning:

   • Enable versioning ✅

   • This protects against accidental overwrites

Note: Versioning doesn't cost extra for our setup since each backup has a unique timestamp-based filename. It's just a safety net in case you manually overwrite something.

6. Encryption:

   • Enable ✅

   • Encryption type: SSE-S3 (Amazon S3 managed keys)

   • Bucket Key: Enable ✅

Note: Bucket Key is for SSE-KMS encryption optimization. Since we're using SSE-S3, this setting doesn't affect us, but it's fine to leave enabled.

7. Object Lock:

   • Disable (not needed for our use case)

Click "Create bucket."

Why These Settings?

Let me explain what we just configured:

ACLs disabled: Modern S3 best practice. We control access through IAM policies, not bucket ACLs.

Block public access: Your database backups should never be publicly accessible. Ever.

Versioning: If you accidentally overwrite a backup, S3 keeps the old version. Extra safety.

Encryption: Your backups are encrypted at rest. If someone physically steals AWS's hard drives (unlikely, but still), they can't read your data.

Step 3: Install AWS CLI on Your Droplet

Now let's get your server set up to talk to AWS.

Connect to Your Droplet

ssh root@YOUR_DROPLET_IP

# Switch to deploy user
su - deploy
cd /opt/strapi-backend

Note: We're connecting as root first because we set up SSH keys for root in Part 2. If you want direct SSH access as the deploy user, you can add your SSH key to /home/deploy/.ssh/authorized_keys.

We'll do all the backup setup as the deploy user, not root.

Check Your Architecture

This step is important and easy to miss. The AWS CLI download is architecture-specific.

uname -m

You'll see either:

• x86_64 - Standard Intel/AMD processors (most common)

• aarch64 - ARM64 processors (some DigitalOcean droplets)

Install AWS CLI

For x86_64 (most common):

# Download installer
curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"

# Install unzip if needed
sudo apt install unzip -y

# Unzip
unzip awscliv2.zip

# Install (use --update flag if AWS CLI already exists)
sudo ./aws/install --update

# Verify installation
aws --version

For aarch64 (ARM64):

# Download ARM version
curl "https://awscli.amazonaws.com/awscli-exe-linux-aarch64.zip" -o "awscliv2.zip"

# Rest is the same
sudo apt install unzip -y
unzip awscliv2.zip
sudo ./aws/install --update
aws --version

You should see something like:

aws-cli/2.x.x Python/3.x.x Linux/x.x.x

Why the --update flag? Some DigitalOcean droplets come with an older AWS CLI version pre-installed. The --update flag safely replaces it with the latest version, or installs fresh if nothing exists. Without this flag, the installer fails if a previous version is detected.

Configure AWS Credentials

Now let's connect your server to your AWS account:

aws configure

You'll be prompted for:

AWS Access Key ID: [paste your key from Step 1]
AWS Secret Access Key: [paste your secret key from Step 1]
Default region name: [your bucket region, e.g., us-east-1]
Default output format: json

Test the connection:

aws s3 ls

You should see your bucket listed. If you get an error, double-check your access keys and region.

Step 4: Create the Backup Script

Now for the main event - the actual backup automation.

Create Backup Directory

# As deploy user
mkdir -p /opt/strapi-backend/backups
chmod 755 /opt/strapi-backend/backups

Note: If you used a different directory for your Strapi project (like /var/www/strapi-backend or /home/deploy/strapi), adjust this path accordingly. Just make sure to use the same path consistently throughout the backup script.

This is where we'll store local copies of backups for 7 days.

Create the Backup Script

nano /opt/strapi-backend/backup-script.sh

Paste this complete script:

#!/bin/bash
# =============================================================================

    log "Database backup created: $BACKUP_FILE"
else
    log "ERROR: Failed to create database backup"
    send_notification "BACKUP FAILED" "pg_dump command failed"
    exit 1
fi

# Check if backup file is not empty
if [ ! -s "$BACKUP_PATH" ]; then

    send_notification "BACKUP SUCCESS" "Backup uploaded: $S3_KEY"

log "File: $BACKUP_FILE.gz"
log "Size: $BACKUP_SIZE"
log "Local: $COMPRESSED_FILE"
log "S3: s3://$S3_BUCKET/$S3_KEY"
log "Backup process completed successfully"

Save and exit (Ctrl+X, Y, Enter).

Update the Configuration

Before the script will work, you need to update it with your actual values:

# Still in the same file (or reopen with nano)
nano /opt/strapi-backend/backup-script.sh

Find and update these lines:

S3_BUCKET="your-backup-bucket-name"  # Change to your actual bucket name
DATABASE_NAME="strapi_staging"       # Change to your database name
DATABASE_CONTAINER="strapi-db"        # Change to your service name (not container_name)

How to find your values:

# Check your docker-compose.stg.yml for service name and container name
grep -B1 "container_name" docker-compose.stg.yml

# This will show you both:
# genkiStrapi:                    <- This is the SERVICE NAME
#   container_name: strapi-backend <- This is the CONTAINER NAME

# Check your .env.stg for database name
grep "DATABASE_NAME" .env.stg

Save your changes.

Make the Script Executable

chmod +x /opt/strapi-backend/backup-script.sh

Important note about service names vs container names:

In Docker Compose, there's a difference between the service name (defined in services: section) and the container_name (the optional name for the actual container).

For the backup script, you should use the service name. If you get errors when running the script, try using the service name instead of the container_name.

Pro tip: Keep your service name and container_name the same (or similar) to avoid confusion. For example:

Understanding the Backup Script

Let me walk through what this script actually does:

1. Configuration Section: Sets up all the variables we need - backup directory, S3 bucket, database details, etc.

2. Logging Function: Every action gets timestamped and logged to backup.log. When something breaks at 3 AM, these logs tell you exactly what happened.

3. Container Check: Before attempting a backup, verify the database container is actually running. No point trying to backup a stopped database.

4. Database Dump: Uses pg_dump to create a complete SQL dump of your database. The -T flag makes it work in automation (no interactive prompts).

5. Empty File Check: Verify the backup actually contains data. I've seen backups "succeed" but create 0-byte files due to permission issues.

6. Compression: Gzip typically reduces PostgreSQL dumps by 80-90%. A 50MB database becomes a 5MB backup.

7. S3 Upload: Upload directly to Standard-IA storage class (cheaper than Standard, same instant retrieval). We organize by year/month for easy browsing.

8. Local Cleanup: Delete backups older than 7 days from local storage. Keeps your disk from filling up.

9. Integrity Check: Verify the compressed file isn't corrupted. Better to know now than during an emergency restore.

Why local retention matters: S3 retrieval costs money (pennies, but still). Keeping a week of local backups means quick restores for recent issues without touching S3.

Step 5: Create the Restore Script

Having backups is great. Being able to actually restore them is better. This script handles the tricky parts of database restoration.

nano /opt/strapi-backend/restore-script.sh

Paste this complete script:

#!/bin/bash
# =============================================================================
# PostgreSQL Restore Script for Strapi
# Safely restores from local or S3 backups with constraint handling

    echo ""

    echo "  $0 strapi_backup_20241214_120000.sql.gz local"

    echo "  $0 list  # List available backups"
    echo ""
    exit 1
}

# List available backups
list_backups() {
    echo "=== Local Backups ==="
    ls -lh $BACKUP_DIR/strapi_backup_*.sql.gz 2>/dev/null || echo "No local backups found"

    echo ""
    echo "=== S3 Backups (Last 10) ==="
    aws s3 ls s3://$S3_BUCKET/backups/ --recursive | grep "\.sql\.gz$" | tail -10 || echo "No S3 backups found"
}

Save and exit.

Update Restore Script Configuration

Same as before, update your specific values:

nano /opt/strapi-backend/restore-script.sh

Update these lines to match your setup:

S3_BUCKET="your-backup-bucket-name"
DATABASE_NAME="strapi_staging"
DATABASE_CONTAINER="strapi-db"        # Use service name
STRAPI_CONTAINER="strapi-backend"    # Use service name

Make it executable:

chmod +x /opt/strapi-backend/restore-script.sh

Understanding the Restore Script

The restore process is more complex than backup because we need to handle database constraints properly.

Why we drop and recreate the database:

Restoring directly into an existing database often fails with errors like:

ERROR: duplicate key value violates unique constraint
ERROR: relation already exists

These errors occur because PostgreSQL's constraints (primary keys, foreign keys, unique indexes) conflict with existing data. The clean solution is to drop the entire database and restore to a fresh one. This ensures a conflict-free restore every time.

The restore flow:

1. Create safety backup: Before touching anything, backup current state

2. Stop Strapi: Prevent new data writes during restore

3. Drop database: Remove all existing data and constraints

4. Create fresh database: Start with a clean slate

5. Restore backup: Import the SQL dump

6. Start Strapi: Bring the application back online

Pre-restore safety backup:

This is the "oh crap" insurance. If the restore goes wrong, you can restore back to the state right before you started.

Step 6: Set Up Lifecycle Policy

Now let's configure S3 to automatically move old backups to cheaper storage and eventually delete them.

Create the Lifecycle Policy

nano /tmp/lifecycle-policy.json

Paste this configuration:

{
    "Rules": [
        {
            "ID": "BackupLifecycleRule",
            "Status": "Enabled",
            "Filter": {
                "Prefix": "backups/"
            },
            "Transitions": [
                {
                    "Days": 30,
                    "StorageClass": "GLACIER"
                }
            ],
            "Expiration": {
                "Days": 120
            }
        }
    ]
}

What this does:

• First 30 days: Backups stay in Standard-IA (instant retrieval if needed)

• After 30 days: Automatically move to Glacier (much cheaper, takes 1-5 minutes to retrieve)

• After 120 days: Automatically delete (4 months of history is plenty for staging)

Apply the policy:

# Replace with your actual bucket name
aws s3api put-bucket-lifecycle-configuration \
    --bucket your-backup-bucket-name \
    --lifecycle-configuration file:///tmp/lifecycle-policy.json

Verify it worked:

aws s3api get-bucket-lifecycle-configuration --bucket your-backup-bucket-name

You should see your lifecycle rule in the output.

Clean up:

rm /tmp/lifecycle-policy.json

Why 30 Days Before Glacier?

This timing is based on S3's minimum storage duration charges.

S3 has minimum storage duration requirements:

• Standard-IA: Minimum 30 days

• Glacier: Minimum 90 days

If you delete or move data before these minimums, you're still charged for the full minimum period. Moving to Glacier after only 7 days would result in:

• 7 days of actual Standard-IA storage

• 23 days of "unused" Standard-IA minimum charges

• Plus Glacier storage costs

By waiting the full 30 days before transitioning to Glacier, you avoid these early deletion penalties and optimize your storage costs.

Step 7: Test the Backup System

Time to verify everything works before setting up automation. This step is crucial - don't skip it.

Test Manual Backup

Let's run a backup manually and watch what happens:

cd /opt/strapi-backend
./backup-script.sh

What you should see:

[2025-12-08 14:30:01] Starting daily backup process...
[2025-12-08 14:30:02] Creating database backup...
[2025-12-08 14:30:03] Database backup created: strapi_backup_20251208_143001.sql

[2025-12-08 14:30:06] Backup file integrity verified
[2025-12-08 14:30:06] === Backup Summary ===
[2025-12-08 14:30:06] File: strapi_backup_20251208_143001.sql.gz
[2025-12-08 14:30:06] Size: 4.2M
[2025-12-08 14:30:06] Local: /opt/strapi-backend/backups/strapi_backup_20251208_143001.sql.gz
[2025-12-08 14:30:06] S3: s3://your-bucket/backups/2025/12/strapi_backup_20251208_143001.sql.gz
[2025-12-08 14:30:06] Backup process completed successfully

If you see errors, we'll troubleshoot in a moment.

Verify the backup file exists locally:

ls -lh /opt/strapi-backend/backups/

You should see your compressed backup file.

Verify it uploaded to S3:

aws s3 ls s3://your-backup-bucket-name/backups/$(date +%Y/%m)/

You should see your backup listed with its size.

Tip: You can also check this visually - just go to your S3 bucket in the AWS console and browse to the backups/2025/12/ folder to see your backup file.

Test Backup Contains Real Data

Let's make sure the backup actually has your data, not just schema:

# Find your latest backup
LATEST_BACKUP=$(ls -t /opt/strapi-backend/backups/strapi_backup_*.sql.gz | head -1)

# Check for data (COPY format)
zcat "$LATEST_BACKUP" | grep -c "COPY.*FROM stdin"

If you see a number greater than 0, your backup contains data. PostgreSQL uses COPY statements to efficiently bulk-insert data.

Some people expect to see INSERT statements. PostgreSQL's pg_dump uses COPY by default because it's much faster. Both are valid backup formats.

Step 8: Test the Restore Process

This is the most important test. A backup system that can't restore is useless.

Important: We're about to restore your database. This will replace all current data with the backup. Make sure you're okay with that, or test on a Friday afternoon when you can rebuild if needed.

List Available Backups

./restore-script.sh list

You should see both your local backup and the S3 backup you just created.

Test Local Restore

Let's test restoring from the local backup first (faster than S3):

Before restoring, let's create verification data:

1. Open your Strapi admin panel: https://api.yourdomain.com/admin

2. Go to Content Manager

3. Create a test entry in any collection (like adding a test article or post)

4. Note what you created - we'll check if it's gone after restore

This test entry should disappear after restore, proving we've successfully reverted to the backup state.

# Get the backup filename from the list command
./restore-script.sh strapi_backup_20251208_143001.sql.gz local

What you should see:

[2025-12-08 14:35:01] Starting restore process...
[2025-12-08 14:35:01] Backup file: strapi_backup_20251208_143001.sql.gz

[2025-12-08 14:35:06] Starting Strapi container...
[2025-12-08 14:35:07] Waiting for Strapi to start (30 seconds)...
[2025-12-08 14:35:37] ✅ Strapi is responding - restore completed successfully!
[2025-12-08 14:35:37] Restore process completed
[2025-12-08 14:35:37] Pre-restore backup available at: /opt/strapi-backend/backups/prerestore_20251208_143501.sql.gz

Verify Strapi is actually working:

# Test from the server
curl http://localhost:1337/admin

# Or open in your browser
# https://api.yourdomain.com/admin

You should see your Strapi admin panel, and your data should be intact.

Verify the restore actually worked:

1. Log into your Strapi admin panel

2. Go to Content Manager

3. Look for the test entry you created earlier

4. It should be gone - this confirms we successfully restored to the backup state before you created that entry

If the test entry is missing, congratulations! Your restore process works correctly.

Test S3 Restore

Now let's test restoring from S3:

./restore-script.sh strapi_backup_20251208_143001.sql.gz s3

The process is the same, but it downloads from S3 first. This tests that your S3 credentials and permissions are working correctly.

Why test S3 restore?

Local backups can get wiped out if your server crashes. S3 is your real safety net. You need to know S3 restores work BEFORE an emergency.

Step 9: Schedule Automated Backups

Everything works manually. Now let's make it automatic.

Set Up Cron Job

We'll use cron to run backups daily at 2:00 AM:

# Edit cron jobs as deploy user
crontab -e

If this is your first time running crontab, it might ask you to choose an editor. Pick nano (usually option 1) if you're unsure.

Add this line:

0 2 * * * /opt/strapi-backend/backup-script.sh >> /opt/strapi-backend/backups/backup.log 2>&1

What this does:

• 0 2 * * * - Run at 2:00 AM every day

• /opt/strapi-backend/backup-script.sh - Run this script

• >> /opt/strapi-backend/backups/backup.log - Append output to log file

• 2>&1 - Redirect errors to the same log file

Save and exit (Ctrl+X, Y, Enter).

Verify Cron Job

# List your cron jobs
crontab -l

You should see the backup job listed.

Check if cron service is running:

sudo systemctl status cron

Should show "active (running)".

Why 2:00 AM?

• Low traffic time (fewer chances of conflicting with user activity)

• After midnight (clean date rollover)

• Before business hours (if something breaks, you'll notice during your workday)

Feel free to adjust to whatever time works for your timezone and usage patterns.

Step 10: Create Monitoring Script

Let's add a simple script to check backup health:

nano /opt/strapi-backend/check-backups.sh

Paste this:

#!/bin/bash
# Quick backup status check script

BACKUP_DIR="/opt/strapi-backend/backups"
S3_BUCKET="your-backup-bucket-name"  # UPDATE THIS!

echo "=== Backup Status Check ==="
echo "Date: $(date)"
echo ""

# Recent local backups
echo "Recent Local Backups (last 7 days):"
find $BACKUP_DIR -name "strapi_backup_*.sql.gz" -mtime -7 -exec ls -lh {} \; | tail -7
echo ""

# Recent S3 backups
echo "Recent S3 Backups (last 5):"
aws s3 ls s3://$S3_BUCKET/backups/ --recursive | grep "\.sql\.gz$" | tail -5
echo ""

# Check backup log for recent activity
echo "Recent Backup Log (last 20 lines):"
tail -20 $BACKUP_DIR/backup.log
echo ""

# Check for errors in recent logs
echo "Recent Errors (if any):"
grep -i "error\|failed\|warning" $BACKUP_DIR/backup.log | tail -5 || echo "No recent errors found"

Update the bucket name and make it executable:

# Update S3_BUCKET in the script
nano /opt/strapi-backend/check-backups.sh

# Make executable
chmod +x /opt/strapi-backend/check-backups.sh

Run it:

cd /opt/strapi-backend
./check-backups.sh

This gives you a quick health check of your backup system. Run it occasionally to make sure backups are happening.

Step 11: Verify Automated Backup (Tomorrow)

The real test is whether the cron job actually runs.

Tomorrow morning, check these things:

# Did the backup run last night?
tail -30 /opt/strapi-backend/backups/backup.log

# Are new backups appearing?
ls -lt /opt/strapi-backend/backups/ | head -5

# Did it upload to S3?
aws s3 ls s3://your-backup-bucket-name/backups/$(date +%Y/%m)/

# Or check manually in AWS console (S3 → your bucket → backups/2025/12/)

# Quick status check
./check-backups.sh

If you see a fresh backup from 2:00 AM, you're golden. The system is running automatically.

Understanding Your Costs

Reality check: A typical Strapi site with 1,000 blog posts, 500 users, and normal metadata would be around 10-20MB. If your database is approaching 100MB, you've either got a very successful site with tons of content, or you might be storing things in PostgreSQL that should live in file storage.

Cost Breakdown (20MB Database Example)

Let's use a typical 20MB database as our example:

Database size: 20MB raw → ~2-4MB compressed (gzip achieves 80-90% compression)

Using 3MB compressed:

Storage costs:

• First 30 days in Standard-IA: 3MB × $0.0125/GB = $0.00004/month

• Days 31-120 in Glacier: 3MB × $0.004/GB × 3 months = $0.00004/month

• Total storage: $0.00008/month

Request costs:

• 30 PUT requests (daily backups): $0.0003/month

• 5 GET requests (occasional restores): $0.0002/month

• Total requests: $0.0005/month

Monthly total: About $0.0006 (less than 1/10th of a penny)

Annual total: About $0.007 (less than one cent per year)

Yeah, it's basically free.

Database Size Reference

Here's what typical database sizes look like for Strapi:

• 5-20MB: Staging environment with test/demo content

• 20-50MB: Active staging or small production with real content

• 50MB+: Successful production site with substantial traffic

Real talk: If your database is consistently over 50MB, you've probably got real users and real traffic. At that point, stop being cheap and get a managed database service like DigitalOcean Managed Database ($15/month) or AWS RDS. The automated backups, monitoring, and not debugging OOM errors at 2 AM are worth way more than the $9/month difference. Your site's success justifies better infrastructure.

What We Built

Let's recap what your backup system now includes:

Automated Protection:

• Daily backups at 2:00 AM

• 7 days of local backups (instant access)

• 120 days of cloud backups (4 months of history)

• Automatic storage optimization (moves to cheaper Glacier after 30 days)

Reliable Recovery:

• Tested restore procedures that actually work

• Handles database constraints properly

• Safety backups before every restore

• Can restore from either local or S3

Monitoring and Maintenance:

• Comprehensive logging of all operations

• Quick status check script

• Automatic cleanup of old local backups

• Integrity verification for every backup

Professional Backup Practices at Budget Cost:

• Offsite backups (different location than your droplet)

• Encrypted storage (S3 server-side encryption)

• Versioning enabled (protects against accidental overwrites)

• Lifecycle management (automatic cost optimization)

All for about $0.001 to $0.20/month depending on your database size.

When to Upgrade

This backup strategy works great for staging and small production environments. Here's when you might want something more robust:

Upgrade triggers:

• Database larger than 50MB

• Compliance requirements (need point-in-time recovery)

• Multiple databases to backup (current script handles one)

• Need faster restore times (replication instead of backups)

• Team needs automated restore testing

Next-level solutions:

• AWS RDS with automated backups (more expensive but easier)

• Continuous replication to a standby database

• Backup validation automation (restore and test automatically)

• Cross-region replication for disaster recovery

But for a $6/month staging environment? Our current setup is perfect.

What's Next?

We've got automated backups protecting your data. That's the safety net in place.

In Part 5 (the final article), we're building a complete CI/CD pipeline with GitHub Actions:

• Automatic builds when you push code

• Security scanning before deployment

• Manual approval workflow (no accidental deploys)

• Automatic deployment to staging

• Rollback procedures if something breaks

• Integration with our backup system

The CI/CD setup ties everything together. Push to your staging branch, approve the deployment, and watch your staging environment update automatically. It's the polish that makes this whole system feel professional.

After Part 5, you'll have:

• Containerized Strapi (Part 1)

• DigitalOcean deployment (Part 2)

• Production web server (Part 3)

• Automated backups (Part 4)

• CI/CD pipeline (Part 5)

That's a complete deployment environment that rivals setups costing 10x more.

New to the series? You can jump in here, but I recommend reading Parts 1-2 first since we're building on that foundation.

Alright, we've got Strapi running on DigitalOcean, accessible via http://YOUR_DROPLET_IP:1337. That works fine for testing, but let's be real - nobody wants to share an IP address with investors or show it to beta users.

"Hey, check out my app at http://167.99.234.123:1337/admin!" Yeah, not exactly inspiring confidence.

In this article, we're setting up Nginx as a reverse proxy, configuring a proper domain with free SSL certificates, and making your setup look and feel production-ready. We're also diving into logs and troubleshooting - the stuff you actually need when things break at 2 AM.

By the end, you'll access your Strapi backend at https://api.yourdomain.com with a proper SSL certificate. Same $6/month cost, way more professional.

Let's get into it.

What We're Building

Here's what this article covers:

• Nginx as a reverse proxy (sitting in front of Strapi)

• Custom domain setup with DNS configuration

• Free SSL certificates from Let's Encrypt

• Automatic HTTP to HTTPS redirects

• Security headers to protect against common attacks

• Complete logging and troubleshooting setup

• Optional port management (closing direct access to Strapi/PostgreSQL)

All of this still runs on your $6/month DigitalOcean droplet. The SSL certificate is free and renews automatically.

Prerequisites

Before we start, make sure you have:

• Parts 1-2 completed (Strapi running on DigitalOcean)

• A registered domain name (from Namecheap, GoDaddy, Google Domains, etc.)

• DNS access to add A records

• SSH access to your droplet

• About 45-60 minutes

Don't have a domain yet? You'll need one for this part. Domain names cost $10-15/year from most registrars. If you're just testing and don't want to buy a domain yet, you can skip to Part 4 and come back to this later.

New to DNS records? No worries - we'll walk through the basics. If you need more detail, there are tons of beginner-friendly guides out there. The main focus of this series isn't DNS configuration, so we'll keep it brief and practical.

Understanding the Architecture

Before we start configuring things, let's talk about what we're actually building and why.

Current Setup (After Part 2):

Internet → Port 1337 → Strapi Container

Users connect directly to Strapi on port 1337. This works but has problems:

• No SSL encryption (traffic is visible)

• Exposing Strapi directly isn't great security

• Can't easily host multiple services

• No request logging or filtering

New Setup (After Part 3):

Internet → Port 443 (HTTPS) → Nginx → Port 1337 → Strapi Container

Nginx sits in front of Strapi and handles:

• SSL/TLS encryption (HTTPS)

• Domain routing

• Security headers

• Request logging

• Rate limiting (if we add it later)

Why this matters: Nginx is battle-tested reverse proxy software used by huge companies. It's better at handling SSL, logging, and security than letting Strapi face the internet directly.

Step 1: Install Nginx

Let's start by installing Nginx on your droplet. We'll need root access for this since we're installing system-level software.

Connect to Your Droplet

ssh root@YOUR_DROPLET_IP

We're connecting as root because we need to install Nginx, configure system files, and manage SSL certificates - all of which require root privileges. We'll switch to the deploy user later when we need to update application files.

Install Nginx

# Update package lists
apt update

# Install Nginx
apt install nginx -y

# Check if it's running
systemctl status nginx

You should see something like:

● nginx.service - A high performance web server
   Active: active (running)

If it says "active (running)", you're golden. Nginx is now running on your server.

Configure Firewall for Web Traffic

Before we can access Nginx from our browser, we need to open the necessary ports:

# Allow HTTP (port 80)
ufw allow 80/tcp

# Allow HTTPS (port 443) - we'll need this soon for SSL
ufw allow 443/tcp

# Verify firewall rules
ufw status

You should now see port 80 and 443 in your firewall rules:

To                         Action      From
--                         ------      ----
22/tcp                     ALLOW       Anywhere
80/tcp                     ALLOW       Anywhere
443/tcp                    ALLOW       Anywhere
1337/tcp                   ALLOW       Anywhere
5432/tcp                   ALLOW       Anywhere

Why we're opening these ports:

• Port 80 (HTTP): Nginx needs this to serve web traffic

• Port 443 (HTTPS): We'll use this for SSL in a few steps

In Part 2, we opened ports 1337 and 5432 for direct Strapi and PostgreSQL access. We'll talk about closing those later once Nginx is handling all web traffic.

Verify Basic Nginx Installation

Now that the firewall is configured, open your browser and visit: http://YOUR_DROPLET_IP

You should see the default Nginx welcome page - "Welcome to nginx!" This confirms Nginx is running and accessible.

If you don't see this page, check your firewall settings from Part 2. Make sure port 80 is allowed.

Step 2: Configure DNS (Point Your Domain to the Droplet)

Before we configure Nginx, we need your domain to point to your DigitalOcean droplet. This is done through DNS A records.

What's an A Record?

An A record tells the internet "when someone types api.yourdomain.com, send them to this IP address." Think of it like adding a contact to your phone - you're associating a name with a number.

Adding the A Record

The exact steps depend on your domain registrar, but the concept is the same everywhere:

Generic Steps:

1. Login to your domain registrar (Namecheap, GoDaddy, etc.)

2. Find DNS settings (might be called "DNS Management", "Advanced DNS", or "Name Servers")

3. Add a new A record:

   • Type: A

   • Host/Name: api (or whatever subdomain you want)

   • Value/Points to: Your droplet IP address

   • TTL: 300 (5 minutes) or leave default

Example:

Type: A
Host: api
Value: 167.99.234.123
TTL: 300

This creates api.yourdomain.com pointing to your droplet.

Verify DNS Propagation

DNS changes can take a few minutes to propagate. Test it:

# From your local machine (not the server)
nslookup api.yourdomain.com

# Or use dig
dig api.yourdomain.com +short

If you see your droplet's IP address in the response, DNS is working! If not, wait 5-10 minutes and try again.

New to DNS or need more detailed instructions for your specific registrar? Google "[your registrar name] add A record" - there are tons of step-by-step guides with screenshots for every major registrar.

Step 3: Configure Nginx as Reverse Proxy
