K8s YAML Validator

This tool validates Kubernetes YAML text for syntax correctness and basic resource structure. It targets DevOps engineers, platform teams, and CI/CD practitioners who author manifests or validate generated configs. By surfacing precise errors with line and column information, it reduces debugging time and deployment delays.
Conceptually, the tool parses YAML, applies lightweight Kubernetes-specific checks (presence of apiVersion, kind, metadata.name), and reports missing or malformed fields. It does not perform full API server validation; instead it focuses on structural integrity to catch common mistakes before runtime.
Key features include multi-document YAML support, per-resource error localization, and optional strict mode that flags unknown fields. Outputs include a validity flag, an array of errors with location data, and a summary count of resources validated.
Use cases include pre-commit checks of new manifests, CI pipeline gates, or local validation during cluster bootstrap. The unique value lies in fast feedback, clear error messages, and minimal configuration, enabling teams to iterate quickly while maintaining baseline quality.
