Wow. I’ve only just started testing it against GP, but it’s really slick and works really well. Lots more fine control than GP, and the only thing that isn’t quite as good is the photo editing on the app and web site, and that is on the roadmap. Oh, and I can’t see how to set up TLS but I might just be missing something.
There is an official helm chart for immich that works very well. Whenever there are breaking changes you may need to update the chart version to apply the breaking changes (ie the recent port change). Doing it with helm chart makes it so you don’t have to do much more than change 2 version numbers on occasion.
