A control plane node is drained. What happens to the mirror Pods for its static Pods?

  1. They are evicted along with everything else
  2. They are deleted and recreated by the kubelet
  3. They block the drain until --force is given
  4. They are left alone, since a static Pod cannot be removed through the API
Show the answer

Answer: D. They are left alone, since a static Pod cannot be removed through the API

drain never deletes mirror Pods, because the real Pod is defined by a manifest on the node and only the kubelet can remove it.
