             Summary: Improve the usability of Flink session cluster on 
Kubernetes
                 Key: FLINK-13380
                 URL: https://issues.apache.org/jira/browse/FLINK-13380
             Project: Flink
          Issue Type: Improvement
          Components: Deployment / Kubernetes
            Reporter: Yun Tang
             Fix For: 1.10.0


Recently, I was launching a Flink session cluster on Kubernetes. However, I 
found current documentation of 
[flink-session-cluster-on-kubernetes|https://ci.apache.org/projects/flink/flink-docs-stable/ops/deployment/kubernetes.html#flink-session-cluster-on-kubernetes]
 and its entrypoint shell script lacks usability:
* flink-conf.yaml is not supported to configure, user have to rebuild docker 
image.
* No explicit documentation of how to submit jobs to session cluster. There 
existed some related question on 
[stackoverflow|https://stackoverflow.com/questions/56910990/flink-on-kubernetes-how-to-submit-jobs-to-session-clusters].
 I think we should add nodeport for 8081 port in deployment yaml.
* Cannot view logs via Flink web UI.
