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.

Well docker tends to be more secure if you configure it right. As far as images go it really is just a matter of getting your images from official sources. If there isn't a image already available you can make one.

The big advantage to containers is that they are highly reproducible. You no longer need to worry about issues that arise when running on the host directly.

Also if you are looking for a container runtime that runs as a local user you should check out podman. Podman works very similarly to docker and can even run your containers as a systemd user service.
