Selfhosted photo manager kind of like Jellyfin

Ideally, there'd be a simple RPM installer compatible with Alma 9 that I can point to a samba share that holds all the photos, kind of like what I do with Jellyfin. Also nice if it uses an otherwise unused port or I can easily set what port it uses.

My googling is finding a bunch of docker stuff, which always seems needlessly complicated to me vs an RPM... I'm also using a low powered x86 tiny computer to front JellyFin and would like to host this on the same computer vs needing another server.

Any ideas?
