About Docker Compose Validator

Parses Docker Compose YAML locally and checks a bounded subset of the current Compose model: a non-empty services mapping, service shapes, image or build sources, port-list shape, dependency targets, and the obsolete top-level version field. It is a quick static preflight rather than a replacement for the Docker CLI.

• Uses a local YAML parser and sends no Compose content anywhere.
• Detects missing dependency targets and common structural mistakes.
• Does not interpolate environment variables, resolve extensions, inspect images, or run Docker.

Frequently Asked Questions

Is this the same as docker compose config?

No. The Docker CLI has the authoritative implementation context, interpolation rules, and platform behavior. Run it before deployment.
