Hi In the apache flink documentation https://ci.apache.org/projects/flink/flink-docs-release-1.4/ops/deployment/kubernetes.html
The order of creating the deployment and services are incorrect. It is mentioned in the order as follows- kubectl create -f jobmanager-deployment.yaml kubectl create -f taskmanager-deployment.yaml kubectl create -f jobmanager-service.yaml But this order of execution would fail if there is sufficient delay between the execution of 2nd and 3rd command. The reason being that the task manager is trying to connect to job manager through service name which is still not up. Ideally the order must be like this- kubectl create -f jobmanager-deployment.yaml kubectl create -f jobmanager-service.yaml kubectl create -f taskmanager-deployment.yaml Regards Sampath
