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.

I concur with most of your points. Docker is a nice thing for some use cases, but if I can easily use a package or set up my own configurations, then I will do that instead of use a docker container every time. My main issues with docker:

Containers are not updated with the rest of the host OS
firewall and mounting complexities which make securing it more difficult
