>             Project: Flink
>          Issue Type: Improvement
>            Reporter: Jesus H Christ
>            Priority: Minor

> Flink on Kubernetes has High Availability services which build an external service for the web ui access.
> [https://sourcegraph.com/github.com/apache/flink@master/-/blob/flink-kubernetes/src/main/java/org/apache/flink/kubernetes/kubeclient/decorators/ExternalServiceDecorator.java]
> In the case of multiple job managers to avoid 15s or so between job manager restarts, a new job manager leader can be elected. In this case I think the service no longer points to the correct job manager as any of the job manager pods can have the jobmanager label.
> It might help to use IPs for JobManagers like Task managers do for HIgh Availabiilty. It might also help to update the service with the new IP or endpoint somehow for the external service to point to.
