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!
People are talking about privacy but the big reason is that it gives you, the owner, control over everything quickly without ads or other uneeded stuff. We are so used to apps being optomized for revenue and not being interoperable with other services that it’s easy to forget the single biggest advantage of computers which is that programs and apps can work together quickly and quietly and in the background. Companies provide products, self-hosting provides tools.
