# Docker Compose Generator
|
|
|
|
Generate production-ready Docker Compose files with best practices.
|
|
|
|
## Configuration Patterns
|
|
|
|
1. **Multi-Service Architecture**: Define all services with dependencies
|
|
2. **Environment Variables**: Use .env files for configuration
|
|
3. **Volume Management**: Persistent data and named volumes
|
|
4. **Network Configuration**: Custom networks for service isolation
|
|
5. **Health Checks**: Service health monitoring
|
|
6. **Resource Limits**: CPU and memory constraints
|
|
|
|
## Example Docker Compose (Full Stack)
|
|
|
|
```yaml
|
|
version: '3.8'
|
|
|
|
services:
|
|
frontend:
|
|
build:
|
|
context: ./frontend
|
|
dockerfile: Dockerfile
|
|
ports:
|
|
- "3000:3000"
|
|
environment:
|
|
- NODE_ENV=production
|
|
- REACT_APP_API_URL=http://api:4000
|
|
depends_on:
|
|
- api
|
|
healthcheck:
|
|
test: ["CMD", "curl", "-f", "http://localhost:3000"]
|
|
interval: 30s
|
|
timeout: 10s
|
|
retries: 3
|
|
networks:
|
|
- app-network
|
|
|
|
api:
|
|
build:
|
|
context: ./api
|
|
dockerfile: Dockerfile
|
|
ports:
|
|
- "4000:4000"
|
|
environment:
|
|
- NODE_ENV=production
|
|
- DATABASE_URL=postgresql://user:pass@postgres:5432/db
|
|
- REDIS_URL=redis://redis:6379
|
|
depends_on:
|
|
postgres:
|
|
condition: service_healthy
|
|
redis:
|
|
condition: service_started
|
|
volumes:
|
|
- ./api/logs:/app/logs
|
|
deploy:
|
|
resources:
|
|
limits:
|
|
cpus: '1'
|
|
memory: 512M
|
|
networks:
|
|
- app-network
|
|
- db-network
|
|
|
|
postgres:
|
|
image: postgres:15-alpine
|
|
environment:
|
|
- POSTGRES_DB=myapp
|
|
- POSTGRES_USER=user
|
|
- POSTGRES_PASSWORD=pass
|
|
volumes:
|
|
- postgres-data:/var/lib/postgresql/data
|
|
- ./init.sql:/docker-entrypoint-initdb.d/init.sql
|
|
healthcheck:
|
|
test: ["CMD-SHELL", "pg_isready -U user"]
|
|
interval: 10s
|
|
timeout: 5s
|
|
retries: 5
|
|
networks:
|
|
- db-network
|
|
|
|
redis:
|
|
image: redis:7-alpine
|
|
command: redis-server --appendonly yes
|
|
volumes:
|
|
- redis-data:/data
|
|
healthcheck:
|
|
test: ["CMD", "redis-cli", "ping"]
|
|
interval: 10s
|
|
timeout: 5s
|
|
retries: 3
|
|
networks:
|
|
- app-network
|
|
|
|
nginx:
|
|
image: nginx:alpine
|
|
ports:
|
|
- "80:80"
|
|
- "443:443"
|
|
volumes:
|
|
- ./nginx.conf:/etc/nginx/nginx.conf:ro
|
|
- ./ssl:/etc/nginx/ssl:ro
|
|
depends_on:
|
|
- frontend
|
|
- api
|
|
networks:
|
|
- app-network
|
|
|
|
volumes:
|
|
postgres-data:
|
|
redis-data:
|
|
|
|
networks:
|
|
app-network:
|
|
driver: bridge
|
|
db-network:
|
|
driver: bridge
|
|
```
|
|
|
|
## Best Practices Included
|
|
|
|
- Service dependencies with health checks
|
|
- Named volumes for data persistence
|
|
- Custom networks for isolation
|
|
- Resource limits for stability
|
|
- Environment variable management
|
|
- Multi-stage builds support
|
|
- Health check configurations
|
|
- Logging and monitoring ready
|
|
|
|
## When Invoked
