CI/CD Pipeline Design

Pipeline Stages

1. Build Stage

• Code Checkout
• Dependencies installieren
• Compilation
• Artifact erstellen

2. Test Stage

• Unit Tests
• Integration Tests
• Code Coverage
• Linting

3. Security Stage

• SAST (Static Analysis)
• Dependency Scan
• Secret Detection
• Container Scan

4. Deploy Stage

• Environment Provisioning
• Artifact Deployment
• Smoke Tests
• Health Checks

GitHub Actions Beispiel

name: CI/CD
on: [push, pull_request]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
      - run: npm ci
      - run: npm run build
      - uses: actions/upload-artifact@v4
        with:
          name: build
          path: dist/

  test:
    needs: build
    runs-on: ubuntu-latest
    steps:
      - run: npm test
      - run: npm run lint

  deploy:
    needs: test
    if: github.ref == 'refs/heads/main'
    runs-on: ubuntu-latest
    steps:
      - run: ./deploy.sh

Parallele Ausführung

• Unabhängige Jobs parallel
• Matrix Builds
• Test Sharding
• Zeit-Optimierung

Caching

Dependency Cache

• node_modules
• pip cache
• Maven/Gradle cache

Build Cache

• Docker Layer Cache
• Incremental Builds

Artifacts

• Build Outputs
• Test Reports
• Coverage Reports
• Logs

Quality Gates

• Minimum Code Coverage
• No Critical Vulnerabilities
• All Tests Passed
• Linting Passed

Secrets Management

• Environment Variables
• Secret Storage (Vault)
• Rotation
• Least Privilege

Environment Promotion

Development → Staging → Production
     ↓           ↓           ↓
  Auto-deploy  Auto-deploy  Manual/Auto

Deployment Strategien

Best Practices

1. Fail Fast (schnelle Tests zuerst)
2. Idempotente Pipelines
3. Immutable Artifacts
4. Infrastructure as Code
5. Automatische Rollbacks
