CI/CD Pipeline Design

Purpose

Design robust CI/CD pipelines that automate building, testing, and deploying applications with quality gates and deployment strategies.

When to Use

• •Setting up new projects
• •Automating deployment processes
• •Implementing quality gates
• •Configuring automated testing

Key Capabilities

1. •Pipeline Design - Structure multi-stage build/test/deploy workflows
2. •Quality Gates - Implement automated testing and code quality checks
3. •Deployment Strategies - Blue-green, canary, rolling deployments

Approach

1. •Define pipeline stages (build, test, deploy)
2. •Configure triggers (push, PR, schedule)
3. •Add quality gates (tests must pass, coverage >80%)
4. •Implement deployment strategies
5. •Add notifications and monitoring

Example

# .github/workflows/ci-cd.yml
name: CI/CD Pipeline

on:
  push:
    branches: [main, develop]
  pull_request:
    branches: [main]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Setup Node
        uses: actions/setup-node@v3
        with:
          node-version: '18'
      - run: npm ci
      - run: npm run build
      - run: npm test
      - name: Upload coverage
        uses: codecov/codecov-action@v3
  
  deploy:
    needs: build
    if: github.ref == 'refs/heads/main'
    runs-on: ubuntu-latest
    steps:
      - name: Deploy to production
        run: |
          ./deploy.sh production

Best Practices

• •✅ Run tests on every commit
• •✅ Fail fast on test failures
• •✅ Use caching to speed up builds
• •✅ Separate build and deploy stages
• •✅ Require code review before merging
• •❌ Avoid: Skipping tests to deploy faster
• •❌ Avoid: Deploying without quality gates
