policies.kyverno.io/description: Define and use labels that identify semantic attributes of your application or Deployment. A common set of labels allows tools to work collaboratively, describing objects in a common manner that all tools can understand. The recommended labels describe applications in a way that can be queried. This policy validates that the label `app.kubernetes.io/name` is specified with some value.
