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'll say that as someone who stopped using docker and went back to deploying from source in lxc containers: dockers is a great tool for the majority of people and that is exactly what it aims to be, easily reusable in as many different setups as possible.

On the flip side, yes it may happen that you would not benefit from docker for a reason or another. I don't, in my case docker only adds another layer over my already containerized setup and many of the services I deploy are already built from source in a CI/CD workflow and deployed through ansible.

I do have other issues with docker but those are usually less with the tool and more with how some project use docker as a mean to replace proper deployment documentations.
