## About this tool

Generate a Dockerfile or Compose service from image, workdir, ports, and command.

How to use: pick Dockerfile or Compose, fill fields, copy. This does not build or push images.

Example: node:22-alpine plus EXPOSE 3000 yields a small Node Dockerfile. Related: GitHub Actions explainer for CI YAML.
