+1 for watchtower. I’ve been using it for about a year now without any issues to keep anywhere from 5 to 10 Docker containers updated.

I switched to moving all of my media services from VMs to containers and haven’t regretted it. Highly recommend that as your approach.

I left xteve off the list of services as well. Very useful if you plan on doing IPTV.

Absolutely. You’re going to be paying for more overhead but I’ve never regretting setting up a cluster. I run mine on a t5500, a dl360 gen 6, and a raspberry pi as a witness.

On the cluster I’m running pfsense, file shares, home assistant, a pihole, and a Debian vm with docker that has containers running radarr, sonarr, watchtower, plex, jackett, and mealie. Also spin up various VMs for testing.
