Why docker (feddit.it)

Hi! Question in the title.

I get that its super easy to setup. But its really worthwhile to have something that:

runs everything as root (not many well built images with proper useranagement it seems)
you cannot really know which stuff is in the images: you must trust who built it
lots of mess in the system (mounts, fake networks, rules...)

I always host on bare metal when I can, but sometimes (immich, I look at you!) Seems almost impossible.

I get docker in a work environment, but on self hosted? Is it really worth while? I would like to hear your opinions fellow hosters.

people are rebuffing the criticism already.

heres the main advantage imo:

no messy system or leftovers. some programs use directories all over the place and it gets annoying fast if you host many services. sometimes you will have some issue that requires you to do quite a bit of hunting and redoing things.

docker makes this painless. you can deploy and redeploy stuff easily and quickly, without a mess. updates are painless and quick too, with everything neatly self-contained.

much easier to maintain once you get the hang of things.

Quick addition, I think for the messy argument the way I would articulate it for folks running servers is it helps you move from pets to cattle.
