Q: about k8s Operator update to 1.1

hi
when I update kubernetes Operator from 1.0 to 1.1 version. I follow the official guide finish the update, it seems all normal. but when I inspect the Operator pods use below command:

`kubectl describe pods couchbase-operator-xxxxxxx`

the result has a warning below:
