Kubernetes Manifest Validator

Run a fast Kubernetes manifest preflight for YAML structure, required identity fields, metadata, and common safety issues.

Run the preflight to see findings.

The manifest is sent to the Go validation API for this check and is not stored or logged.

Structural preflight

Catch blockers before cluster admission

Catch obvious deployment blockers before kubectl reaches a cluster. The first version performs structural preflight; versioned OpenAPI validation is planned for the professional scanner.

Current checks

  • Check apiVersion, kind, and metadata
  • Validate multi-document manifests
  • Catch tabs and missing resource names

Validation boundary

This preflight checks identity fields and common structural or safety signals. It does not know installed CRDs, admission policies, or live cluster state. Use a server-side dry run against the authorized target cluster as the final check.
