About this tool
Docker Compose Validator
The Docker Compose Validator checks service definitions, depends_on conditions, named volume declarations, network mode validity, and inline secret detection.
• Validate a Compose file before docker compose up in a new environment
• Check depends_on condition syntax before a deployment that requires startup ordering
• Detect hardcoded secrets in environment: blocks before committing to version control
• Verify named volume declarations before a production deployment

FAQ
What does this tool tell you?
The Docker Compose Validator checks service definitions, depends_on conditions, named volume declarations, network mode validity, and inline secret detection.
What affects the result most?
Version field deprecated in Compose v2: top-level 'version' is ignored — remove from new files. depends_on with condition: depends_on: service: condition: service_healthy — waits for healthcheck. Named volumes: volumes declared at top level, referenced in services — prevents anonymous volume accumulation.
How should I use the result?
Treat the tool's output as a first-pass check, not a proof of correctness. A clean pass means no issues in the patterns this tool recognizes; a failure points to a specific problem you can investigate in your source. The underlying spec is the authoritative source for edge cases.
