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.

  • Podman solves the root issue
  • you can inspect the stuff. You don't have to, but it helps if you're not paranoid with popular and widespread images
  • I have no mess

It's great that you do install things on bare metal, I did that in the beginning until I discovered docker and I will never go back. Docker/ podman compose is just so good

Out of curiosity, what reverse proxy docker do you use that can run rootless in podman? My main issue, and feel free to correct me if I am wrong, is that most of them require root. And then its not possible to easily connect those containers into the same network as your rootless containers so then your other containers have to be root anyways. I don't really want my other containers to be host accessible, I want them to be only accessible from within the podman network that the reverse proxy has access to.

And then there's issues where you have to enable lingering processes for normal users and also let it access ports < 1024, makes using docker-compose a pain, etc. I haven't really found a good solution for rootless, but I really want to eventually move that way.
