How to auto update podman containers
My main resource is the podman documentation
There is a podman-auto-update.service systemd service. It was not enabled on my fedora atomic GNOME installation.
You can start it with systemctl start podman-auto-update.service It'll auto update daily at 00:00.
For a container to auto update, you have to add
labels:
- "io.containers.autoupdate=registry"
to the compose.yml file, otherwise it won't be updated. (only auto update if you specify it)
Make sure that the image is specified correctly with the source, e.g. ghcr.io/advplyr/audiobookshelf or docker.io/jellyfin/jellyfin.
You can then run podman auto-update --dry-run and if you are satisifed with it, test the first auto update with podman auto-update.
You can start it with systemctl start podman-auto-update.service It’ll auto update daily at 00:00.
Be aware you need to enable and start
podman-auto-update.timerfor this to work automatically (iesystemctl enable --now podman-auto-update.timer), this command will just update the images once only.I don't think this works for non-system podman images, so you'd have to do
systemctl --user enable --now podman-auto-update.timerfor each user.thanks for the addition!
Yeah, works great in my experience, but requires a bit of care if the upstream container packager is only doing a "latest" tag and not major version tags that are unlikely to break compatibility.
