FeatureRequest: In regards to a container having a healthcheck and the update function

[Leopere]

The issue I often see with automated self-updating containers is that many package maintainers don't design proper stateless containers and often an auto-updater like Ouroboros and Watchtower two very unsafe options, in my opinion, have zero awareness of the status of the updated container.

If Diun could possibly check if the container was running and healthy if health-checks are available of course, and then ensure that the replaced updated container reaches a healthy state before considering the upgrade to be complete.

This could be done with a combination of backing up the old container image with one of the functions docker has and then restoring the old image when the newer one turns out faulty.

Like I said in #1, unlike other tools like WatchTower, Diun is not intended to update containers but only to send notifications when an image is updated on a registry.

Yes feel free to close this.
