--------------------------------------------------------------------
[~gyfora] I think my assumption is wrong about the flink-conf configmap as even
with native mode the rpc.address is not set in flink-conf.yaml (file is
read-only) but the advertised address is correct in cluster configmap. May be
due to something else. You can try with the basic-checkpoint-ha-example and
switch the mode to "standalone".
Update: I think may be retrieving Pod IP requires Service Acccount which is not
used in "standalone" mode?

> Key: FLINK-30518
> URL: https://issues.apache.org/jira/browse/FLINK-30518
> Project: Flink
> Issue Type: Bug
> Components: Kubernetes Operator
> Affects Versions: kubernetes-operator-1.3.0
> Reporter: Binh-Nguyen Tran
> Priority: Major
> Attachments: flink-configmap.png, screenshot-1.png
>
>
> -Since flink-conf.yaml is mounted as read-only configmap, the
> /docker-entrypoint.sh script is not able to inject correct Pod IP to
> `jobmanager.rpc.address`. This leads to same address (e.g flink.ns-ext) being
> set for all Job Manager pods. This causes:-
> Setting up FlinkDeployment in Standalone mode with Kubernetes HA Service.
> Problems:
> (1) flink-cluster-config-map always contains wrong address for all 3
> component leaders (see screenshot, should be pod IP instead of clusterIP
> service name)
> (2) Accessing Web UI when jobmanager.replicas > 1 is not possible with error
> {code:java}
> {"errors":["Service temporarily unavailable due to an ongoing leader
> election. Please refresh."]} {code}
>
> ~ flinkdeployment.yaml ~
> {code:java}
> spec:
> mode: standalone
> flinkConfiguration:
> high-availability: kubernetes
> high-availability.storageDir: "file:///opt/flink/storage"
> ...
> jobManager:
> replicas: 3
> ... {code}
