Summary: [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 Environment: ~ flinkdeployment.yaml ~ ``` spec: flinkConfiguration: high-availability: kubernetes high-availability.storageDir: "file:///opt/flink/storage" ... jobManager: replicas: 3 ``` Reporter: Binh-Nguyen Tran Attachments: flink-configmap.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: (1) flink-cluster-config-map always contains same address for all 3 component leaders (see screenshot) (2) Accessing Web UI when jobmanager.replicas > 1 is not possible with error ``` {"errors":["Service temporarily unavailable due to an ongoing leader election. Please refresh."]} ``` -- This message was sent by Atlassian Jira (v8.20.10#820010)
