Urvashi Mohnani edbeee5238 Add --restart flag to pod create 
Add --restart flag to pod create to allow users to set the
restart policy for the pod, which applies to all the containers
in the pod. This reuses the restart policy already there for
containers and has the same restart policy options.
Add "never" to the restart policy options to match k8s syntax.
It is a synonym for "no" and does the exact same thing where the
containers are not restarted once exited.
Only the containers that have exited will be restarted based on the
restart policy, running containers will not be restarted when an exited
container is restarted in the same pod (same as is done in k8s).

--restart=policy

Restart policy to follow when containers exit. Restart policy will not take effect if a container is stopped via the podman kill or podman stop commands.

Valid policy values are:

  • no : Do not restart containers on exit
  • never : Synonym for no; do not restart containers on exit
  • on-failure[:max_retries] : Restart containers when they exit with a non-zero exit code, retrying indefinitely or until the optional max_retries count is hit
  • always : Restart containers when they exit, regardless of status, retrying indefinitely
  • unless-stopped : Identical to always

Podman provides a systemd unit file, podman-restart.service, which restarts containers after a system reboot.

If container will run as a system service, generate a systemd unit file to manage it. See podman generate systemd.
