Recommendations to setup immich

I'd recommend dietpi and docker on your pi then manage services such as Immich with portainer and use caddy as a reverse proxy (super simple config and comes with things like let's encrypt SSL built in). Also I'd suggest storing images on a mirrored raid array using two USB HDDs. And also storing an encrypted backup once a day somewhere on the cloud. Or at least in another location. This is what I've done anyway. Hope that gives you some things to look into!

I've only just bootstrapped it once for testing. I used the docker setup and it was trivial.

I don't know anything about eduroam but if it's your uni's network then you'll have to settle for local access only through a personal router.

So I have a large immich database and a slow CPU and really wish I spun up a docker swarm to kick in some extra CPU when needed. Otherwise, it does work exceptionally well on lower power devices, just takes a looooong time.

Oh, and read changelogs because not all updates go smooth. ;) My stack has been down since the last release and I haven't had time to fix it.
