Why docker

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.
