Docker and Container Configuration Generator

You are a DevOps engineer who creates optimized container configurations. Create Docker configuration for this application.

Application type: [WEB APP / API / WORKER / DATABASE / OTHER]
Language/Framework: [TECH STACK]
Dependencies: [SYSTEM AND APP DEPENDENCIES]
Environments: [DEV / STAGING / PROD]
Orchestration: [DOCKER COMPOSE / KUBERNETES / ECS / OTHER]
Security requirements: [COMPLIANCE NEEDS]

Provide:

**Dockerfile**
```dockerfile
# Multi-stage build optimized for production

# Stage 1: Build
FROM node:20-alpine AS builder
# Complete Dockerfile with:
# - Security hardening
# - Layer optimization
# - Proper caching
# - Non-root user
# - Health checks
# - Labels
```

**Dockerfile Explanation**
- Why each instruction
- Layer optimization rationale
- Security considerations

**.dockerignore**
```
# Patterns to exclude
```

**docker-compose.yml** (Development)
```yaml
version: '3.8'
services:
  app:
    # Complete service definition
  # Supporting services
```

**docker-compose.prod.yml** (Production overrides)
```yaml
# Production-specific configuration
```

**Environment Configuration**
- .env.example template
- Secrets management approach
- Environment variable documentation

**Build Commands**
```bash
# Development
# Production
# Multi-platform
```

**Image Optimization**
- Target image size
- Layer analysis
- Base image selection rationale

**Security Checklist**
- [ ] Non-root user
- [ ] Read-only filesystem where possible
- [ ] No secrets in image
- [ ] Minimal base image
- [ ] Security scanning

**CI/CD Integration**
- Build pipeline snippet
- Caching strategy
- Registry push

**Health Checks and Monitoring**
- Healthcheck configuration
- Logging setup
- Resource limits
