| 52 | |
| 53 | ## Instructions |
| 54 | |
| 55 | When working on infrastructure: |
| 56 | |
| 57 | 1. **Security First**: IAM least privilege, secrets management, network policies |
| 58 | 2. **Reproducibility**: Infrastructure as Code over manual configuration |
| 59 | 3. **Monitoring**: Include observability in all deployments |
| 60 | 4. **Cost Awareness**: Consider cost implications of architecture choices |
| 61 | 5. **Documentation**: Document architecture decisions and runbooks |
| 62 | |
| 63 | ## CI/CD Patterns |
| 64 | |
| 65 | ### GitHub Actions |
| 66 | |
| 67 | ```yaml |
| 68 | name: CI |
| 69 | on: [push, pull_request] |
| 70 | jobs: |
| 71 | test: |
| 72 | runs-on: ubuntu-latest |
| 73 | steps: |
| 74 | - uses: actions/checkout@v4 |
| 75 | - uses: actions/setup-node@v4 |
| 76 | with: |
| 77 | node-version: "20" |
| 78 | cache: "npm" |
| 79 | - run: npm ci |
| 80 | - run: npm test |
| 81 | - run: npm run build |
| 82 | ``` |
| 83 | |
| 84 | ### Pipeline Stages |
| 85 | |
| 86 | 1. **Build**: Compile, transpile, bundle |
| 87 | 2. **Test**: Unit, integration, E2E |
| 88 | 3. **Security**: SAST, dependency scan |
| 89 | 4. **Quality**: Lint, type check |
| 90 | 5. **Deploy**: Stage -> Production |
| 91 | |
| 92 | ## Containerization |
| 93 | |
| 94 | ### Dockerfile Best Practices |
| 95 | |
| 96 | ```dockerfile |
| 97 | FROM node:20-alpine AS builder |
| 98 | WORKDIR /app |
| 99 | COPY package*.json ./ |
| 100 | RUN npm ci --only=production |
| 101 | |
| 102 | FROM node:20-alpine |
| 103 | WORKDIR /app |
| 104 | COPY --from=builder /app/node_modules ./node_modules |
| 105 | COPY . . |
| 106 | USER node |
| 107 | EXPOSE 3000 |
| 108 | CMD ["node", "server.js"] |
| 109 | ``` |
| 110 | |
| 111 | ## Deployment Strategies |
| 112 | |
| 113 | - Rolling updates (zero-downtime) |
| 114 | - Blue-green deployment |
| 115 | - Canary releases |
| 116 | - Feature flags for progressive rollout |
