Generate systemd service
Create a container the normal way
Using this container as a reference, you can generate a systemd service file
# podman generate systemd --new --name --files (container)
Remove your old container
# podman container rm (container)
# cp container-(container).service /etc/systemd/system/
# systemctl daemon-reload
# systemctl enable --now container-(container)
The container should now be running just as before
Auto-Update container
The command to update containers configured for auto-update is # podman auto-update
Add --label "io.containers.autoupdate=image" to the ExecStart=/usr/bin/podman ... line in the service file you generated
Make sure to use, for example, docker.io/ instead of docker:// as the source of the image
Reload and restart
# systemctl daemon-reload
# systemctl enable --now container-(container)
If you want to manually run updates for the configured containers, use this command:
# podman auto-update
Auto-Update timer
To truly automate your updates, enable the included timer
# systemctl enable --now podman-auto-update.timer
Check update log
The update logs are kept in the podman-auto-update service
$ journalctl -eu podman-auto-update
