Docker Compose YAML explainer

AI

Paste a Compose file or a fragment with services and networks. You will get a structured walkthrough of services, ports, and storage—without starting any containers.

Compose YAML

?
Paste compose.yaml or docker-compose.yml. Nothing is run here—redact registry passwords and env secrets.

Common use cases

  • Review a stack before merge: ports, env names, and volume mounts between services.
  • Pair with the Dockerfile explainer when build: context points to the same repo.
  • Compare with Kubernetes or systemd when the same app moves between compose and clusters.

Common mistakes to avoid

  • Pasting production secrets in environment: blocks

    Use placeholders in examples. Prefer env_file or secrets references in real repos.

  • Assuming explanations match your Compose spec version

    v2 vs v3+ and Compose v2 CLI differ; verify keys against your installed spec.
