Introduction
Podman[^1] has a nice feature called generate that lets you generate
different kinds of configuration files for starting pods. One that I use often
is podman generate systemd which generates a new user service that can be
started with systemctl --user start container-yourcontainer.service or
enabled.
Auto-Updating Containers
If you want your container to auto update you can simply pass it the flag
--label "io.containers.autoupdate=registry" when you're creating it. The
systemd service will automatically pull the latest versions of containers
before starting them. You can manually update your container images now using
podman auto-update.
If you want to update your images on a schedule you can enable the
podman-auto-update.timer using `systemctl --user enable --now
podman-auto-update.timer` which will auto update your containers every Monday
morning.[^2]
Kubernetes YAML Generation
You can also generate a Kubernetes YAML configurations using `podman generate
kube`. This can then be loaded in Kubernetes to run your containers.
