Summary: Improve Kubernetes HA Services docs
Key: FLINK-30743
URL: https://issues.apache.org/jira/browse/FLINK-30743
Project: Flink
Issue Type: Improvement
Components: Documentation
Reporter: Wolfgang Buchner
i recently tried to setup a flink standalone session cluster with kubernetes HA
and needed to adjust configmap RBACs settings via try & error because the
documentation of:
*
[https://nightlies.apache.org/flink/flink-docs-release-1.16/docs/deployment/ha/kubernetes_ha/]
*
[https://nightlies.apache.org/flink/flink-docs-release-1.16/docs/deployment/resource-providers/standalone/kubernetes/#high-availability-with-standalone-kubernetes]
didn't state everything which was needed. E.g. for configmap resource the verb
"watch" is essential.

I was finally able to configure the k8s HA instance.
I will try to provide a PR containing some documentation improvements.
