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.

Docker can be run rootless. Podman is rootless by default.

I build certain containers from scratch. Very popular FOSS software can be trusted, but if you're as paranoid, you should probably run the bare-minimum software in the first-place.

It's a mess if you're not used to it. But yes, normal unix networking is somewhat simpler (like someone mentioned, LXC containers can be a decent idea). Well, you'll realise that Docker is not really top-dog in terms of complexity when you start playing with the big boys like full-fledged k8s
