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.

Podman solves the root issue
you can inspect the stuff. You don't have to, but it helps if you're not paranoid with popular and widespread images
I have no mess

It's great that you do install things on bare metal, I did that in the beginning until I discovered docker and I will never go back. Docker/ podman compose is just so good

Dive is a great tool for inspecting docker images. I wish I found it sooner.
