| Doc Text: |
Cause:
In certain cases NotFound error was swallowed by controller logic.
Consequence:
Missing NotFound event was causing the controller not be aware of missing pods.
Fix:
Properly react to NotFound events, which indicate that the pod was already removed by a different actor.
Result:
Controller (deployment, daemonset, replicaset and others) will properly react to pod NotFound event.
