Kubernetes zombie pods problem

Question

I try to run ha redis with kubernetes and I have a problem with deleted pods. When the node which redis master is working on dies, pod that should die keeps working invisibly and also creating new pod so I can't access redis master with a service. I use redis sentinel for failover and when the node which redis master is working on dies, a slave replaces master and the slave becomes the new master. Hidden pods prevent this because the sentinel thinks the master is not dead and adds the newly created redis instance to the cluster as a slave.

My yaml file is like this:

apiVersion: apps/v1
kind: StatefulSet

  name: redis

    app: redis
