Hello, 

I'm trying to setup Flink in Kubernetes using the Application Mode as described here: https://ci.apache.org/projects/flink/flink-docs-master/docs/deployment/resource-providers/standalone/kubernetes

The doc mentions that there needs to be a aervice exposing the JobManager’s REST and UI ports.  It then points to a link w/ the resource definitions: https://ci.apache.org/projects/flink/flink-docs-master/docs/deployment/resource-providers/standalone/kubernetes/#application-cluster-resource-definitions and I defined the following service along w/ the jobmanager, taskmanager, and flink-conf. 

apiVersion: v1
kind: Service
metadata:
  name: flink-jobmanager
spec:
  type: ClusterIP
  ports:
  - name: rpc
    port: 6123
  - name: blob-server
    port: 6124
  - name: webui
    port: 8081
  selector:
    app: flink
    component: jobmanager

I am able to access the jobmanager UI but the taskmanagers are failing w/ the following error:

Could not resolve ResourceManager address akka.tcp://flink@flink-jobmanager:6123/user/rpc/resourcemanager_*

Any ideas about this?  

Thanks
