Hi Hemant, Thanks for trying the native Kubernetes integration and share your feedback.
Pod template is a supplementary feature for those advanced features(e.g. volume mounts, sidecar container, init container, etc.), which are not supported by Flink config options[1]. By default, Flink is using an empty pod template to initialize the JobManager/TaskManager pod, then it is decorated internally. For example, set the pod resources(mem, cpu), the starting commands, as well as the image and etc. However, not all the fields could be configured via pod template. Like the pod resource you mentioned, it needs to be configured via Flink config options. I believe you could find the detailed information in the documentation[2]. If you want to capture and store the metrics, the prometheus reporter should be right direction[3].
