Kubernetes Manifest Validator

Validate Kubernetes YAML manifests for the most common errors: missing apiVersion/kind, missing required fields for the kind, typos in field names, image-pull policy / resource-limit misses, and security-context omissions.

How to use the Kubernetes Manifest Validator

Paste your manifest (single doc or YAML-stream of multiple docs separated by ---). The validator parses YAML, identifies each resource's kind, and runs kind-specific checks.

What this catches (vs kubectl --dry-run)

This is a lightweight structural check: missing required fields, common typos, security defaults you should set. It does NOT do full schema validation against your cluster's API server. For production CI, run kubectl --dry-run=server against your real cluster or use kubeconform for offline schema validation. This tool is for the quick "is this manifest sane?" pass before you copy-paste it.

Frequently asked questions

What does it check for?
Missing apiVersion or kind, required fields for the detected kind, field-name typos, image pull policy and resource-limit omissions, and common security-context gaps.

Does it validate against the live cluster schema?
No. It checks structure and common mistakes in the browser. For full schema validation against your cluster version, run kubeconform or kubeval in CI.

Is my manifest uploaded?
No. Validation runs entirely in your browser, so your YAML never leaves your machine.
