YAML Validator

Catch mistakes in Kubernetes manifests before they hit a cluster.

What it checks

  • Well-formed YAML — indentation, duplicate keys, and parse errors.
  • Kubernetes shape — required fields like apiVersion, kind, and metadata.name, and obvious structural problems.
  • Multi-document files — ----separated manifests are validated document by document.

How to use it

  1. Open the YAML Validator in the Workbench.
  2. Paste or type your manifest.
  3. Read inline findings as you edit — problems are flagged with their location.

It's a fast feedback loop for authoring manifests, fixing a snippet from a blog post, or sanity-checking generated YAML before you apply it.
