What is Docker? (lemmy.world)
submitted 1 year ago* (last edited 1 year ago) by Jofus@lemmy.world to c/selfhosted@lemmy.world

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!

It usually comes down to privacy and independence from big tech, but there are a ton of other reasons you might want to do it. Here are some more:

  • preservation - no longer have to care if Google kills another service
  • cost - over time, Jellyfin could be cheaper than a Netflix sub
  • speed - copying data on your network is faster than to the internet
  • hobby - DIY is fun for a lot of people

For me, it's a mix of several of reasons.
