Docker Containerization

Prompt

Create a production-ready Docker setup for a [language/framework] application. Application: [brief description]. Services needed: [app, database, cache, etc.]. Write: Dockerfile with multi-stage build (development and production stages), docker-compose.yml with all services, .dockerignore file, environment variable handling, health checks for each service, volume mounts for persistence, network configuration, and README instructions for local setup. Follow Docker security best practices (non-root user, minimal base image).
