On exit code for application kubernetes will restart the container inside the POD and pod state will change to in Ready column.

if you want to terminate pod gracefully you can have a look at this : https://dzone.com/articles/gracefully-shutting-down-java-in-containers

Terminated: Indicates that the container completed its execution and has stopped running. A container enters into this when it has successfully completed execution or when it has failed for some reason. Regardless, a reason and exit code is displayed, as well as the container’s start and finish time. Before a container enters into Terminated, preStop hook (if any) is executed.

      State:          Terminated
        Reason:       Completed
        Exit Code:    0
        Started:      Wed, 30 Jan 2019 11:45:26 +0530
        Finished:     Wed, 30 Jan 2019 11:45:26 +0530
