Best Learning Resources for CI/CD and GitHub Actions

Since you're completely new to CI/CD, I'll break this down step-by-step and provide you with the best resources to learn.

What is CI/CD?

CI/CD stands for:

• Continuous Integration (CI): Automatically testing and building your code every time you push changes
• Continuous Deployment/Delivery (CD): Automatically deploying your code to production after tests pass

Think of it as: "Every time I push code, GitHub automatically tests it, builds it, and deploys it for me"

Best Learning Resources

1. GitHub's Official Documentation (Start Here!)

• GitHub Actions Quickstart
• Understanding GitHub Actions
• GitHub Actions Tutorial

Why start here? It's free, well-structured, and teaches you GitHub Actions specifically (which is what you'll use).

2. FreeCodeCamp YouTube Tutorial

• GitHub Actions Tutorial - Basic Concepts and CI/CD Pipeline (free, ~1 hour)
• Great visual explanations for beginners

3. GitHub Skills Interactive Courses

• GitHub Actions: Hello World
• Continuous Integration
• Hands-on learning directly in GitHub repositories

4. Fireship YouTube Channel

• GitHub Actions in 100 Seconds
• Quick, visual overview to understand concepts fast

Your Learning Path (Step-by-Step)

Step 1: Understand the Basics (Day 1-2)

1. Watch the Fireship 100-second video
2. Read GitHub's "Understanding GitHub Actions" guide
3. Complete the "Hello World" GitHub Skills course

Step 2: Create Your First Workflow (Day 3-4)

Create a .github/workflows/ folder in your repository and add a simple workflow:

name: My First Workflow

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Say hello
        run: echo "Hello, GitHub Actions!"

Push this to your repo and watch it run in the "Actions" tab!

Step 3: Build a Real CI/CD Pipeline (Day 5-7)

For a Node.js project:

name: Node.js CI/CD

on:
  push:
    branches: [ main ]

jobs:
  build-and-test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      
      - name: Setup Node.js
        uses: actions/setup-node@v4
        with:
          node-version: '20'
      
      - name: Install dependencies
        run: npm install
      
      - name: Run tests
        run: npm test
      
      - name: Build
        run: npm run build

For a Python project:

name: Python CI/CD

on:
  push:
    branches: [ main ]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      
      - name: Setup Python
        uses: actions/setup-python@v5
        with:
          python-version: '3.11'
      
      - name: Install dependencies
        run: |
          python -m pip install --upgrade pip
          pip install -r requirements.txt
      
      - name: Run tests
        run: pytest

Common Use Cases & Examples

1. Deploy to GitHub Pages

name: Deploy to GitHub Pages

on:
  push:
    branches: [ main ]

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Deploy
        uses: peaceiris/actions-gh-pages@v3
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          publish_dir: ./public

2. Deploy to Vercel/Netlify

name: Deploy to Vercel

on:
  push:
    branches: [ main ]

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: amondnet/vercel-action@v20
        with:
          vercel-token: ${{ secrets.VERCEL_TOKEN }}
          vercel-org-id: ${{ secrets.ORG_ID }}
          vercel-project-id: ${{ secrets.PROJECT_ID }}

3. Run Tests on Pull Requests

name: PR Tests

on:
  pull_request:
    branches: [ main ]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Run tests
        run: npm test

Key Concepts to Understand

1. Workflows: YAML files in .github/workflows/ that define your automation
2. Events: What triggers the workflow (push, pull_request, schedule, etc.)
3. Jobs: Groups of steps that run on the same runner
4. Steps: Individual tasks (running commands, using actions)
5. Actions: Reusable units of code (like actions/checkout@v4)
6. Runners: Virtual machines that execute your workflows

Pro Tips

✅ Start simple - just run a "Hello World" first
✅ Use existing actions from the GitHub Marketplace
✅ Check the "Actions" tab in any popular GitHub repo to see real examples
✅ Test locally with act before pushing
✅ Use secrets for sensitive data (Settings → Secrets → Actions)

Next Steps

1. Pick a project (even a simple one)
2. Add a basic workflow that runs tests
3. Gradually add build and deployment steps
4. Experiment and break things - that's how you learn!
