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!
Worst part about docker: insane volume management.
Agreed, I just spent a week (very intermittently) trying to figure out where all my free space had gone, turns out it was a bunch of abandoned docker volumes taking up. I have 32gb on my laptop, so space is at an absolute premium.
I guess I learned my lesson about trying out docker containers on my laptop just to check them out.
