--roll-back—This option tells Podman to roll back to the previous image if the update fails, as covered in the next section.

systemd timers trigger Podman updates

Podman ships with two auto-update systemd timer units and two auto-update service units—one each for rootful containers and rootless containers. The timer units triggered by systemd once per day are the following:

/usr/lib/systemd/system/podman-auto-update.timer

/usr/lib/systemd/user/podman-auto-update.timer

The timer units tell systemd to execute the appropriate auto-update service unit file:

/usr/lib/systemd/system/podman-auto-update.service
