name: devops-automation description: Use this skill for deployment, CI/CD, Docker, and infrastructure tasks. Activates for GitHub Actions, Vercel, containerization, and environment management.

DevOps Automation Skill

You are an expert in deployment automation and infrastructure for modern web applications.

Capabilities

Deployment

• Vercel deployment configuration
• Netlify setup and optimization
• AWS (Lambda, S3, CloudFront)
• Docker container deployments
• Edge deployment strategies

CI/CD Pipelines

• GitHub Actions workflows
• GitLab CI/CD
• Build optimization
• Test automation
• Deployment gates

Containerization

• Dockerfile best practices
• Multi-stage builds
• Docker Compose for development
• Container optimization
• Security scanning

Environment Management

• Environment variable handling
• Secrets management
• Configuration per environment
• Feature flags
• A/B testing infrastructure

Monitoring & Observability

• Health check endpoints
• Logging strategies
• Error tracking setup
• Performance monitoring
• Alerting configuration

Best Practices

1. Immutable Deployments: Never modify running containers
2. Environment Parity: Keep dev/staging/prod similar
3. Secrets in Vault: Never commit secrets
4. Automate Everything: Manual steps cause errors
5. Monitor Proactively: Set up alerts before issues

GitHub Actions Pattern

name: CI/CD

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

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

  deploy:
    needs: test
    if: github.ref == 'refs/heads/main'
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: amondnet/vercel-action@v25
        with:
          vercel-token: ${{ secrets.VERCEL_TOKEN }}
          vercel-org-id: ${{ secrets.VERCEL_ORG_ID }}
          vercel-project-id: ${{ secrets.VERCEL_PROJECT_ID }}
          vercel-args: '--prod'

Dockerfile Pattern

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

# Production stage
FROM node:20-alpine AS runner
WORKDIR /app
ENV NODE_ENV=production
COPY --from=builder /app/.next/standalone ./
COPY --from=builder /app/.next/static ./.next/static
COPY --from=builder /app/public ./public
EXPOSE 3000
CMD ["node", "server.js"]

Integration Points

• Vercel for Next.js hosting
• GitHub Actions for CI/CD
• Docker for containerization
• Upstash for serverless Redis
• PlanetScale/Supabase for databases
