What is docker-compose Linter?

docker-compose linter that surfaces errors, warnings and best-practice suggestions (missing refs, no healthcheck, 'latest' tag…) with line numbers.

How to use this tool?

Paste your docker-compose.yml and get a structured list of errors, warnings, and suggestions.

Benefits

  • Line numbers
  • Best practices
  • Syntax highlighting
  • No upload
  • 100% browser

Frequently Asked Questions

Which rules are checked?
YAML syntax, image/build presence, port format, named volume/network refs, depends_on, restart, healthcheck, mem_limit, 'latest' tags.
Is the file sent to a server?
No, parsing uses js-yaml + a custom rule engine, all in your browser.
Are my secrets safe?
No outbound calls — but avoid pasting secrets in any web tool. Use a .env file instead.
