CI/CD Pipelines

Automating Delivery

CI/CD automates building, testing, and deploying code changes.

Continuous Integration

• Automatically build on every commit
• Run tests to catch regressions
• Lint and format checks
• Security scanning

Continuous Deployment

• Automatically deploy to staging
• Manual approval for production
• Blue-green or canary deployments
• Rollback capabilities

GitHub Actions Example

name: CI
on: [push, pull_request]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 20
      - run: npm ci
      - run: npm test
      - run: npm run build

Pipeline Stages

1. Build - Compile and package
2. Test - Unit, integration, e2e
3. Analyze - Security, quality
4. Deploy - Staging then production
