--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
• 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

Please note that restart will not restart containers after a system reboot. If this functionality is required in your environment, you can invoke Podman from a systemd.unit(5) file, or create an init script for whichever init system is in use. To generate systemd unit files, please see podman generate systemd.
