Docker Compose validator
Validate Docker Compose against the official schema.
Catch invalid keys and types with precise paths and lines, then analyze references, ports, dependencies, security, storage, and operational readiness locally in your browser.
Docker Compose → Validation report
Run official-schema, structural, security, and portability checks locally.
Your Docker Compose validation report will appear here.
Checks the official Compose schema with precise paths and lines, plus references, port collisions, dependency cycles, security, resources, and health checks.
What it converts
Useful output, with the mappings made visible.
- Official Compose Specification errors with precise paths and source lines
- Service dependencies, networks, volumes, secrets, configs, and host ports
- Images, privileges, namespaces, capabilities, resources, health checks, and environment values
What to review
Generated does not mean ready to deploy.
- Final interpolation and resolved output from docker compose config
- Whether flagged host access is intentional for the workload
- Environment-specific limits, paths, ports, and external resources
Validate against the official Compose Specification.
ComposeMorph validates recognized keys, value types, nesting, and required fields against the official Compose schema. Errors include the affected configuration path and source line, while the existing analyzer checks relationships and deployment risks the schema cannot see.
- Find references to missing resources
- Detect conflicting host ports and dependency problems
- Review privileges, host access, capabilities, health checks, and resource limits
Use the browser report before docker compose config.
The validator gives you an official-schema and operational review without Docker or an upload. Run docker compose config afterward to resolve variables, paths, overrides, and the final environment-specific model.
Common questions
Questions about this tool and its output.
Is this a Docker Compose schema validator?
Yes. ComposeMorph uses the official Compose Specification schema for keys, types, nesting, and required fields, then adds relationship, security, and portability checks that schema validation cannot provide.
Can I validate compose.yaml without installing Docker?
Yes. Paste the file for immediate official-schema and operational validation in your browser. You only need Docker to resolve the final environment-specific configuration and run the stack.
Is my Docker Compose file uploaded?
No. The file is parsed and analyzed locally in your browser, so service names, images, environment values, and infrastructure details do not leave the device.
