Docker Development Guide
This skill MUST be loaded when ANY Dockerfile, docker-compose.yml, docker-compose.override.yml, .dockerignore, or Docker-related configuration file is being read, reviewed, edited, or created. Also use when the user asks to "create a Dockerfile", "write a multi-stage build", "add a .dockerignore", "set up docker-compose", "containerize an application", "optimize a Docker image", "reduce Docker image size", "fix Docker build issues", "add health checks to containers", "set up a local dev environment with Docker", "create a multi-service setup", "debug container startup", "configure Docker volumes", "set up database containers", or mentions Dockerfile, Docker Compose, multi-stage builds, container images, build context, layer caching, ENTRYPOINT, CMD, docker-compose.yml, Docker health checks, or container orchestration for local development.
