verify-compose

Docker Compose validation checks YAML syntax, image references, network and volume definitions, and service dependencies to catch errors before they reach production. This Skill automatically scans your docker-compose.yml for configuration issues, invalid resource references, and port conflicts, outputting a structured report of any problems found.

Validation detects YAML syntax errors, invalid image references, undefined networks or volumes, improper environment variable usage, duplicate service names, and port collisions. It ensures all cross-service dependencies are correctly wired and that configurations are sound across development, staging, and production environments.

Yes, this Skill validates docker-compose.yml files across development, staging, and production scenarios. It applies the same checks—syntax correctness, service integrity, resource definitions, and dependency validation—regardless of environment, helping catch context-specific configuration issues.

Run validation immediately after making changes to your docker-compose.yml, such as adding a new service or updating existing ones. This catches configuration errors early before deployment, preventing runtime failures and ensuring all services, networks, and volumes are correctly defined.

Yes, port collision detection is built in. The Skill identifies duplicate service names and conflicting port assignments that could cause runtime problems, ensuring your container orchestration setup is free of resource conflicts.
