setup-docker

What this skill does

Writes a multi-stage Dockerfile and compose file that match your stack. Picks slim Node, Python, or Go base images, copies only the files you need, and uses a separate runtime stage to keep the image small. Adds a .dockerignore, healthcheck, and a docker-compose.yaml with sensible defaults for local development.

Use cases

• Containerising a new service for production
• Shrinking an oversized image with multi-stage builds
• Standing up a local dev environment with one command
• Preparing an app for deployment to Fly.io, Render, or Kubernetes
