Hi! Im new to self hosting. Currently i am running a Jellyfin server on an old laptop. I am very curious to host other things in the future like immich or other services. I see a lot of mention of a program called docker.
search this on The internet I am still Not very clear what it does.
Could someone explain this to me like im stupid? What does it do and why would I need it?
Also what are other services that might be interesting to self host in The future?
Many thanks!
EDIT: Wow! thanks for all the detailed and super quick replies! I’ve been reading all the comments here and am concluding that (even though I am currently running only one service) it might be interesting to start using Docker to run all (future) services seperately on the server!
Interesting idea (snap over docker).
I wonder, does using snap still give you the benefit of not having to maintain specific versions of 3rd party software?
Snap is like Flatpak. So it will store and maintain as many versions of dependencies as your applications need. So it gives you that benefit by automating the work for you. The multiple versions still exist if your apps depend in different versions.
I don’t know too much about snap (I literally haven’t had to touch my immich setup) but as far as I remember when I set it up that was snap’s whole thing - it maintains and updates itself with minimal administrative oversight.
