Is it possible to mount node local disk for task managers in a k8s application cluster?

Hi,

We use the per-job deployment mode to deploy our Flink services on Kubernetes. We're considering to move from the per-job mode to the application mode in view of the advantages of the application mode. However, it seems that `bin/flink run-application --target kubernetes-application` does not support to configure the task managers to mount volumes from the node local disk (volumes - hostPath) according to https://ci.apache.org/projects/flink/flink-docs-stable/deployment/config.html#kubernetes. If it is feasible, please let me know which option should be used. If not, could I create an issue for this feature. Thanks.

Best regards,
Chen-Che Huang

 I think the pod template[1] is what you are looking for. It will be released in 1.13.

Best,
