SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Docker workflows and production-ready images often suffer from bloated sizes, slow builds, and insecure configurations. This Skill provides a structured approach to optimize Dockerfiles, implement robust multi-stage builds, and configure Compose-based orchestration to improve build times, image footprints, and runtime security.

Core Features & Use Cases

Dockerfile optimization: layer ordering, cache usage, and combined RUN commands to shorten build times.
Multi-Stage Build workflows: isolate dependencies, minimize final image size, and produce production-ready artifacts.
Docker Compose orchestration: health checks, networks, resources, and environment separation for dev vs prod.
Complete examples: guidance and patterns for optimized images and safe deployments in Node.js, Python, or similar microservices.

Quick Start

Apply the Docker Expert workflow to refactor a Dockerfile into a multi-stage, cache-friendly production image with proper security and compose-ready configurations.
