I have a deployment template as below. but the prestop hook is never been executed at all. the idea here is set the zookeeper node offline before the pod is terminated.

I am running kubectl rollout to restart the pods. and old pod is when it terminates the prestop is not run. could someone please check whats wrong ?

Basically how its prestop executed in case of successful stop ? I need this feature because the zookeeper is involved here and the api connects to zookeeper to send the requests.
