CI/CD Optimizer

CI/CD 优化器

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

优化CI/CD流水线以实现更快的构建与可靠的部署。

Quick Start

快速开始

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

并行执行任务、缓存依赖项、使用更小的镜像、实现健康检查、自动回滚。

并行执行：

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

Docker layer caching:

**缓存依赖项：**
```yaml
- uses: actions/cache@v3

    key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}

Deployment Strategies

部署策略

Blue-green deployment:

yaml

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:

yaml

- 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 }}

蓝绿部署：

yaml

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"}}}'

金丝雀部署：

yaml

- 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

最佳实践

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

优先执行代码检查/测试以快速失败
使用矩阵构建适配多版本
缓存依赖项与构建产物
使用更小的Docker镜像
实现自动回滚
添加健康检查
监控流水线指标
