Question

You directly create a ReplicaSet named 'web-rs' with a replica count of 3. Shortly after all 3 Pods are running, you manually delete one of them with 'kubectl delete pod'. What happens next, and why?

Accepted Answer

The ReplicaSet controller observes that only 2 Pods match its selector and creates a new Pod to return to the desired count of 3.

Answer

Nothing happens automatically; you must manually recreate the deleted Pod because ReplicaSets do not self-heal.

Answer

The ReplicaSet scales down to 2 replicas permanently, since deleting a Pod updates its desired state.

Answer

The entire ReplicaSet is deleted because removing a managed Pod breaks the owner reference.
