Finding version info

description: |
  Kube-apiserver is the front-end for the Kubernetes control plane. It validates and configures data
  for the api objects which include pods, services, replicationcontrollers, and others. The API
  Server services REST operations and provides the frontend to the cluster’s shared state through
  which all other components interact.

  documentation](https://kubernetes.io/docs/reference/command-line-tools-reference/kube-apiserver/).
