Hi Till,
  
The full information when I run command ' kubectl get all’  like this:

NAME                                     READY   STATUS    RESTARTS   AGE
pod/flink-jobmanager-85bdbd98d8-ppjmf    1/1     Running   0          2m34s
pod/flink-taskmanager-74c68c6f48-6jb5v   1/1     Running   0          2m34s

NAME                       TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)    
                  AGE
service/flink-jobmanager   ClusterIP   10.103.207.75   <none>        
6123/TCP,6124/TCP,8081/TCP   2m34s
service/kubernetes         ClusterIP   10.96.0.1       <none>        443/TCP    
                  5d2h

NAME                                READY   UP-TO-DATE   AVAILABLE   AGE
deployment.apps/flink-jobmanager    1/1     1            1           2m34s
deployment.apps/flink-taskmanager   1/1     1            1           2m34s

NAME                                           DESIRED   CURRENT   READY   AGE
replicaset.apps/flink-jobmanager-85bdbd98d8    1         1         1       2m34s
replicaset.apps/flink-taskmanager-74c68c6f48   1         1         1       2m34s

And I can open flink ui but the task manger is 0 ,so the job manger is work well
I think the problem is taksmanger can not register itself to jobmanger,  did I 
miss some configure?
