>There aren't many solutions around for automatically pulling and running new images.

Isn't that exactly what watchtower does?

https://github.com/containrrr/watchtower

It works great on my mediacenter server running deluge, plex, sonarr, radarr, jackett and OpenVPN in docker.

Well, yes. Curiously enough, (IIRC) watchtower started out automatically pulling new images when available. Then the maintainers found that approach to be worse than proper orchestration and disabled the pulling. Perhaps it's different now.

My experience with watchtower is that it kept breaking stuff (or maybe just pulling broken images?)

My server was much more stable after it didn’t try to update all the time any more.

I wonder if I can set a minimum timeout.

Watchtower runs the images if they update, but AFAIK it doesn't pull if the base image changes.

Then again, Harbormaster doesn't do that either unless the upstream git repo changes.

I've heard about Watchtower (auto update) and DUIN (docker image update notifier), but I haven't quite found something that will "just tell me what updates are available, on a static site".

I want to "read all available updates" at my convenience, not get alerts reminding me to update my server.

Maybe I need to write some sort of plugin to DUIN that appends to a text file or web page or SQLite db... Hm.

Looks like https://crazymax.dev/diun/notif/script/ would be useful for that.

Personally, since I’m a big fan of RSS, I’d set up email in Diun and send it to an email generated by https://kill-the-newsletter.com/
