Description

Recently, I was launching a Flink session cluster on Kubernetes. However, I found current documentation of 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. I think we should add nodeport for 8081 port in deployment yaml.
• Cannot view logs via Flink web UI.
