🚀 CI/CD Pipeline Skill

GitHub Actions Workflows

Basic CI Workflow

# .github/workflows/ci.yml
name: CI
on:
  push:
    branches: [main, develop]
  pull_request:
    branches: [main]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: '20'
          cache: 'npm'
      - run: npm ci
      - run: npm run lint
      - run: npm test
      - run: npm run build

Deploy to Vercel

# .github/workflows/deploy.yml
name: Deploy
on:
  push:
    branches: [main]

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: amondnet/vercel-action@v25
        with:
          vercel-token: ${{ secrets.VERCEL_TOKEN }}
          vercel-org-id: ${{ secrets.VERCEL_ORG_ID }}
          vercel-project-id: ${{ secrets.VERCEL_PROJECT_ID }}
          vercel-args: '--prod'

Deployment Strategies

Environment Management

Secrets Setup

env:
  DATABASE_URL: ${{ secrets.DATABASE_URL }}
  API_KEY: ${{ secrets.API_KEY }}

# Environment-specific
jobs:
  deploy-staging:
    environment: staging
  deploy-production:
    environment: production
    needs: deploy-staging

Branch Protection

on:
  push:
    branches:
      - main      # Production
      - develop   # Staging
      - 'feature/*'  # Feature branches

Docker Build Pipeline

jobs:
  docker:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      
      - name: Login to Docker Hub
        uses: docker/login-action@v3
        with:
          username: ${{ secrets.DOCKER_USERNAME }}
          password: ${{ secrets.DOCKER_PASSWORD }}
      
      - name: Build and push
        uses: docker/build-push-action@v5
        with:
          push: true
          tags: user/app:latest
