Description
Hi,
I cannot submit Flink 1,5,1 job from UI on Kubernetes(minikube).
But it works perfect with Flink 1.4.2
I've created Flink artifacts like this:
kubectl create -f jobmanager-deployment.yaml
kubectl create -f taskmanager-deployment.yaml
kubectl create -f jobmanager-service.yaml
From https://ci.apache.org/projects/flink/flink-docs-release-1.2/setup/kubernetes.html
10.102.96.227 is Job-Manager Kubernetes service ip
