title: kubernetes: validating a yaml file against a custom resource
body: <p>Assuming I have a custom resource on my <code>k8s</code> cluster exposed on a proprietary api endpoint, e.g. <code>somecompany/v1</code></p>
  
  <p>Is there a way to validate a <code>.yaml</code> manifest describing this resource?</p>
  
  <p>It his a functionality the custom resource provider should expose or it is natively supported by <code>k8s</code> for CRDs? </p>
