# CI/CD Architect

## GitHub Actions Workflows

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

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

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      
      - name: Setup Node.js
        uses: actions/setup-node@v4
        with:
          node-version: '20'
          cache: 'pnpm'
      
      - name: Install dependencies
        run: pnpm install --frozen-lockfile
      
      - name: Lint
        run: pnpm lint
      
      - name: Type check
        run: pnpm typecheck
      
      - name: Test
        run: pnpm test:ci
      
      - name: Upload coverage
        uses: codecov/codecov-action@v3
        with:
          files: ./coverage/lcov.info

  build:
    needs: test
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      
      - name: Build Docker image
        run: docker build -t trinity-app:${{ github.sha }} .
      
      - name: Push to registry
        run: |
          echo ${{ secrets.DOCKER_TOKEN }} | docker login -u ${{ secrets.DOCKER_USER }} --password-stdin
          docker push trinity-app:${{ github.sha }}
```

### Deployment Pipeline
```yaml
# .github/workflows/deploy.yml
name: Deploy

on:
  workflow_run:
    workflows: [CI]
    branches: [main]
    types: [completed]

jobs:
  deploy-staging:
    if: github.event.workflow_run.conclusion == 'success'
    runs-on: ubuntu-latest
    environment: staging
    steps:
      - name: Deploy to staging
        run: |
          ssh ${{ secrets.SSH_USER }}@${{ secrets.STAGING_HOST }} \
            "docker pull trinity-app:${{ github.sha }} && \
             docker-compose up -d"

  deploy-production:
    needs: deploy-staging
    runs-on: ubuntu-latest
    environment: production
    steps:
      - name: Deploy to production
        run: |
          ssh ${{ secrets.SSH_USER }}@${{ secrets.PROD_HOST }} \
            "docker pull trinity-app:${{ github.sha }} && \
             docker-compose up -d"
      
      - name: Notify Slack
        uses: 8398a7/action-slack@v3
        with:
          status: ${{ job.status }}
          channel: '#deployments'
```

## Docker Configuration

### Multi-Stage Build
```dockerfile
# Dockerfile
FROM node:20-alpine AS base

# Dependencies
FROM base AS deps
RUN apk add --no-cache libc6-compat
WORKDIR /app
COPY package.json pnpm-lock.yaml ./
RUN npm install -g pnpm && pnpm install --frozen-lockfile

# Builder
FROM base AS builder
WORKDIR /app
COPY --from=deps /app/node_modules ./node_modules
COPY . .
RUN npm run build

# Production
FROM base AS runner
WORKDIR /app
ENV NODE_ENV=production

RUN addgroup --system --gid 1001 nodejs
RUN adduser --system --uid 1001 nextjs

COPY --from=builder /app/public ./public
COPY --from=builder --chown=nextjs:nodejs /app/.next/standalone ./
COPY --from=builder --chown=nextjs:nodejs /app/.next/static ./.next/static

USER nextjs
EXPOSE 3000
ENV PORT=3000
CMD ["node", "server.js"]
```

## Docker Compose

```yaml
# docker-compose.yml
version: '3.8'

services:
  app:
    build: .
    ports:
      - "3000:3000"
    environment:
      - DATABASE_URL=${DATABASE_URL}
      - REDIS_URL=${REDIS_URL}
    depends_on:
      - db
      - redis
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:3000/api/health"]
      interval: 30s
      timeout: 10s
      retries: 3

  db:
    image: postgres:16-alpine
    environment:
      POSTGRES_USER: ${DB_USER}
      POSTGRES_PASSWORD: ${DB_PASSWORD}
      POSTGRES_DB: ${DB_NAME}
    volumes:
      - postgres_data:/var/lib/postgresql/data
    ports:
      - "5432:5432"

  redis:
    image: redis:7-alpine
    ports:
      - "6379:6379"

volumes:
  postgres_data:
```

## Terraform Infrastructure

```hcl
# terraform/main.tf
terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 5.0"
    }
  }
}

provider "aws" {
  region = var.aws_region
}

# ECS Cluster
resource "aws_ecs_cluster" "main" {
  name = "${var.project_name}-cluster"
  
  setting {
    name  = "containerInsights"
    value = "enabled"
  }
}

# ECS Service
resource "aws_ecs_service" "app" {
  name            = "${var.project_name}-service"
  cluster         = aws_ecs_cluster.main.id
  task_definition = aws_ecs_task_definition.app.arn
  desired_count   = var.desired_count
  launch_type     = "FARGATE"
  
  network_configuration {
    subnets          = aws_subnet.public[*].id
    security_groups  = [aws_security_group.ecs.id]
    assign_public_ip = true
  }
}
```

## Release Management

### Semantic Versioning Script
```typescript
// scripts/release.ts
import { execSync } from 'child_process';

async function release(versionType: 'patch' | 'minor' | 'major') {
  // Run tests
  execSync('npm test', { stdio: 'inherit' });
  
  // Bump version
  const newVersion = execSync(`npm version ${versionType}`).toString().trim();
  
  // Generate changelog
  execSync('npx conventional-changelog -p angular -i CHANGELOG.md -s');
  
  // Create git tag
  execSync(`git tag -a ${newVersion} -m "Release ${newVersion}"`);
  
  // Push
  execSync('git push origin main --tags');
  
  console.log(`Released ${newVersion}`);
}
```
