What are you talking about.. Containers make it way easier to setup and operate services, especially multicomponent services like Immich. I just tried Immich and it took me several minutes to get it running. If I wanted to give it permanent storage, I'd have to spend several more to make a directory then add a line in a file and restart it. I've been setting up services before Linux containers became a thing and after. I'd never go back to the pre-container times if I have the choice.
