> - once a pod has been scheduled onto a node, it never reschedules it anywhere else. The node may be experiencing problems, thus the pod is affected. k8s doesn't do anything to heal that -- it could simply delete the pod so it is rescheduled somewhere else.

Can you please elaborate this? When you are using replication controllers or deployments, don’t they drive the state to the desired/goal state, which is N replicas of a pod? So when the node is shut down, I guess it should be rescheduling those dead pods somewhere else to satisfy the goal state?
