HI Team, I am currently exploring flink-kubernetes operator. I was going through all yaml files. I am kind of java only guy. Anyone have any idea to do it java way, I found flink-kuberentes-operator is written in java only. Any help would be really appreciated. I know its bit idiotic but still if anyone have any idea.

You can use the standard Kubernetes Java client with https://mvnrepository.com/artifact/org.apache.flink/flink-kubernetes-operator-api and deploy Flink jobs programmatically.
