CI/CD Pipeline Best Practices

Continuous Integration and Continuous Deployment are essential for modern software delivery. Let's explore how to build effective pipelines.

The CI/CD Philosophy

Core principles for automation:

• Automate everything from build to deployment
• Fail fast with early testing
• Consistent environments across stages

Pipeline Stages

Typical Workflow

1. Code commit triggers build
2. Run unit tests
3. Static code analysis
   • Linting
   • Security scanning
4. Build artifacts
5. Deploy to staging
6. Integration tests
7. Deploy to production

10      - name: Run tests
11        run: npm test
12      - name: Build
13        run: npm run build
14      - name: Deploy
15        if: github.ref == 'refs/heads/main'
16        run: ./deploy.sh

Deployment Strategies

"If it hurts, do it more frequently."

• Martin Fowler

Key Metrics

Track these for pipeline health:

• Build success rate
  • Target: > 95%
  • Investigate failures immediately
• Long build times Optimize for speed
• Deployment frequency

GitHub Actions is a great starting point for CI/CD!
