CI CD Optimizer

CI/CD Optimizer

Optimize CI/CD pipelines for faster builds and reliable deployments.

Quick Start

Parallelize jobs, cache dependencies, use smaller images, implement health checks, automate rollbacks.

Instructions

Pipeline Optimization

Parallel execution:

# GitHub Actions
jobs:
  test:
    strategy:
      matrix:
        node: [14, 16, 18]
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-node@v3
        with:
          node-version: ${{ matrix.node }}
      - run: npm test

Caching dependencies:

- uses: actions/cache@v3
  with:
    path: ~/.npm
    key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}

Docker layer caching:

# Order layers by change frequency
FROM node:18-alpine
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run build

Deployment Strategies

Blue-green deployment:

deploy:
  steps:
    - name: Deploy to green
      run: kubectl set image deployment/app app=myapp:${{ github.sha }} --record
    - name: Wait for rollout
      run: kubectl rollout status deployment/app
    - name: Run smoke tests
      run: ./smoke-tests.sh
    - name: Switch traffic
      run: kubectl patch service app -p '{"spec":{"selector":{"version":"green"}}}'

Canary deployment:

- name: Deploy canary (10%)
  run: kubectl set image deployment/app-canary app=myapp:${{ github.sha }}
- name: Monitor metrics
  run: ./check-metrics.sh
- name: Promote to 100%
  run: kubectl set image deployment/app app=myapp:${{ github.sha }}

Best Practices

• Fail fast with linting/tests first
• Use matrix builds for multiple versions
• Cache dependencies and build artifacts
• Use smaller Docker images
• Implement automated rollbacks
• Add health checks
• Monitor pipeline metrics
