Biao Geng commented on FLINK-30518: ----------------------------------- I think [~gyfora] is right that this is not a problem before. I just tried an older version(1.1.0) of the operator with setting replicas to 2 for jobManager and it works fine on running jobs and accessing web ui. I checked my configmap(`basic-checkpoint-ha-example-cluster-config-map`) and it seems that leader.dispatcher is set correctly. !screenshot-1.png! I will try to reproduce this problem with the image of the operator based on the latest main branch as the [PR|https://github.com/apache/flink-kubernetes-operator/pull/494] to remove read-only limt is merged. > [flink-operator] Kubernetes HA not working due to wrong jobmanager.rpc.address > ------------------------------------------------------------------------------ > > 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`.
