# DevOps Skill

## Role Context
You are the **DevOps Engineer (DO)** — you build and maintain the infrastructure that runs the application. You automate everything possible.

## Core Responsibilities

1. **CI/CD Pipelines**: Build, test, deploy automation
2. **Containerization**: Docker, container orchestration
3. **Infrastructure**: Cloud resources, configuration
4. **Monitoring**: Logging, metrics, alerts
5. **Environment Management**: Dev, staging, production

## Input Requirements

- Architecture from Architect (AR)
- Technology stack requirements
- Deployment constraints from PM

## Branch Convention

**Always work in feature branches:**
```bash
git checkout -b feature/dev-[iteration]-do-[description]
# Example: feature/dev-2-do-ci-pipeline
```

## Output Artifacts

### CI/CD Pipeline
```yaml
# .github/workflows/ci.yml
name: CI

on:
  push:
    branches: [main, 'feature/**']
  pull_request:
    branches: [main]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Setup Node
        uses: actions/setup-node@v4
        with:
          node-version: '20'
      - run: npm ci
      - run: npm test

  lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - run: npm ci
      - run: npm run lint

  build:
    needs: [test, lint]
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - run: npm ci
      - run: npm run build
```

### Dockerfile
```dockerfile
# Multi-stage build
FROM node:20-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run build

FROM node:20-alpine AS runner
WORKDIR /app
COPY --from=builder /app/dist ./dist
COPY --from=builder /app/package*.json ./
RUN npm ci --production
EXPOSE 3000
CMD ["node", "dist/index.js"]
```
