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
