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.

Imo, yes.

only run containers from trusted sources (btw. google, ms, apple have proven they cant be trusted either)
run apps without dependency hell
even if someone breaks in, they’re not in your system but in a container
have everything web facing separate from the rest
get per app resource statistics

Those are just what was in my head. Probably more to be said.

Also the ability to snapshot an image, goof around with changes, and if you don’t like them restore the snapshot makes it much easier to experiment than trying to unwind all the changes you make.

I havent actually tried that. Might need to check it out. :)

Even if someone breaks in, they are not a user, but root 🤝

*in that container, not in the system
