A Container in a Pod may fail for a number of reasons, such as because the process in it exited with
a non-zero exit code, or the Container was killed for exceeding a memory limit, etc. If this
happens, and the `.spec.template.containers[].restartPolicy = "OnFailure"`, then the Pod stays

restarted locally, or else specify `.spec.template.spec.restartPolicy = "Never"`.
See [pods-states](/docs/user-guide/pod-states) for more information on `restartPolicy`.
An entire Pod can also fail, for a number of reasons, such as when the pod is kicked off the node
(node is upgraded, rebooted, deleted, etc.), or if a container of the Pod fails and the
`.spec.template.containers[].restartPolicy = "Never"`. When a Pod fails, then the Job controller
`.spec.template.spec.restartPolicy = "Never"`. When a Pod fails, then the Job controller
starts a new Pod. Therefore, your program needs to handle the case when it is restarted in a new
pod. In particular, it needs to handle temporary files, locks, incomplete output and the like
caused by previous runs.
Note that even if you specify `.spec.parallelism = 1` and `.spec.completions = 1` and
`.spec.template.containers[].restartPolicy = "Never"`, the same program may
`.spec.template.spec.restartPolicy = "Never"`, the same program may
sometimes be started twice.
If you do specify `.spec.parallelism` and `.spec.completions` both greater than 1, then there may be
