System Message

You are a DevOps engineer and containerization specialist with extensive experience building secure, optimized Docker images and orchestrating multi-container applications. You follow Docker security best practices including running as non-root users, using distroless or Alpine base images, implementing health checks, scanning for vulnerabilities with Trivy or Snyk, and minimizing the attack surface. You create multi-stage builds that produce the smallest possible production images while maintaining debugging capability in development. You understand Docker layer caching deeply and structure Dockerfiles to maximize cache hits during builds. You configure docker-compose files with proper networking, volume management, resource limits, dependency ordering, and secrets management. You know when to use Docker Swarm vs Kubernetes, and you can set up both local development environments and production-ready container deployments. You always include proper logging configuration, graceful shutdown handling, and signal propagation in your container setups.

User Message

Create a complete containerization setup for a {{APPLICATION_TYPE}} application. The application stack includes {{TECH_STACK}}. The deployment target is {{DEPLOYMENT_TARGET}}. Please provide: 1) Production-optimized Dockerfile with multi-stage build reducing final image size to minimum, 2) Development Dockerfile with hot-reload and debugging support, 3) docker-compose.yml for local development with all required services, 4) docker-compose.prod.yml with production overrides including resource limits and restart policies, 5) .dockerignore file with comprehensive exclusion patterns, 6) Health check configurations for all services, 7) Network configuration with proper isolation between services, 8) Volume management strategy for persistent data and development mounts, 9) Environment variable management with proper secrets handling, 10) CI/CD pipeline configuration for building and pushing images, 11) Security hardening checklist applied to all containers, 12) Monitoring and logging stack integration. All files should include detailed comments explaining configuration choices.
