It helps DevOps engineers and developers catch configuration problems before deployment."},{"question":"How do I use Docker Compose Validator?","answer":"Paste your docker-compose.yml content into the editor and the tool validates it instantly. It checks YAML syntax, service structure, dependency references, port conflicts, and highlights common mistakes with clear explanations."},{"question":"Is Docker Compose Validator free?","answer":"Yes. This tool is free to use with immediate access—no account required."},{"question":"Does Docker Compose Validator store or send my data?","answer":"No. All processing happens entirely in your browser. Your data never leaves your device — nothing is sent to any server."},{"question":"What kinds of errors does it detect?","answer":"It detects YAML syntax errors, invalid service keys, circular depends_on references, missing referenced services, port conflicts between services, invalid volume mount syntax, and other common Docker Compose configuration mistakes."}],"howTo":[{"title":"Paste your docker-compose.yml","description":"Copy your entire docker-compose file and paste it into the validator. It checks YAML syntax and Docker Compose structure immediately."},{"title":"Review validation results","description":"See a list of errors, warnings, and info messages with line numbers. Common issues: undefined services, missing dependencies, invalid syntax."},{"title":"Fix common errors","description":"Errors like 'service not found' indicate a service reference that doesn't exist. 'Invalid version' means your Compose file version is outdated."},{"title":"Check service dependencies and networks","description":"The validator shows which services depend on others and whether they're on the same network. Fix connectivity issues before deploying."},{"title":"Verify secrets and volume mounts","description":"Ensure all volume paths exist and secret names are consistent. The validator flags paths that may not exist or volumes defined incorrectly."}],"agentContract":{"toolId":"docker-compose-validator","contractVersion":"2.0.0","remote_callable":true,"remote_mode":"dedicated_api","risk_class":"H","max_input_bytes":524288,"timeout_ms":8000,"supports_streaming":false,"preferred_surface":"dedicated_api","dedicated_api":{"baseUrl":"https://aidevhub.io/api/docker-compose-validator/","openapiUrl":"https://aidevhub.io/api/openapi.yaml","endpoints":[{"method":"GET","path":"/api/docker-compose-validator/","summary":"GET docker-compose-validator"},{"method":"POST","path":"/api/docker-compose-validator/","summary":"POST docker-compose-validator"}],"riskClass":"H","inputMaxBytes":524288,"timeoutMs":8000},"runtime":{"endpoint":"/api/tools/run/","methods":["GET","POST"],"queryParams":[{"name":"toolId","required":true,"description":"Tool identifier"},{"name":"a","required":true,"description":"Primary input"}],"postBodyShape":{"toolId":"string","input":"{ a, b?, c?, mode? }"},"exampleGet":"https://aidevhub.io/api/tools/run/?toolId=docker-compose-validator&a=...","policy":{"riskClass":"H","limit":10,"burst":5,"windowSec":60,"inputMaxBytes":524288,"timeoutMs":8000,"cacheTtlSec":0,"networkEnabled":false,"supportsStreaming":false}}},"relatedTools":[{"id":"config-validator","name":"YAML/JSON5 Config Validator","url":"/config-validator/","category":"devtools"},{"id":"env-file-manager","name":"Env File Manager","url":"/env-file-manager/","category":"devtools"},{"id":"yaml-json","name":"YAML ↔ JSON Converter","url":"/yaml-json/","category":"converter"},{"id":"cli-ux-linter","name":"CLI UX Linter","url":"/cli-ux-linter/","category":"devtools"},{"id":"ai-cli-generator","name":"AI CLI Generator","url":"/ai-cli-generator/","category":"devtools"},{"id":"csv-endpoint-builder","name":"CSV Endpoint Builder","url":"/csv-endpoint-builder/","category":"devtools"}]}}
