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

      Dive is a great tool for inspecting docker images. I wish I found it sooner.

      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.

      Do you have a preferred resource? I’m setting up my NAS and starting to prepare for setting up containers. In the meantime it’s just static storage until I get comfortable

      Need to study podman probably, stuff running as root is my main dislike.

      Probably if in only used docker images created by me I would be less concerned of losing track of what I am really deploying, but this would deflect the main advantage of easy deploy?

      Portability is a point I didn’t considered too… But rebuilding a bare metal server properly compatimentized took me a few hours only, so is that really so important?

            Unfortunately I do not have a source but to me it was like podman would replace docker as the container technology since red hat focuses on podman and not docker anymore and kubernetes doesn’t support docker anymore. Transitioning obviously takes ages because of companies being very slow.

              I hope you’re wrong… With RH’s recent choices in regard of FOSS… I really hope podman won’t replace docker. Specially in the self-hosted/FOSS community !

                What’s wrong with podman?

                It’s still many many years away. Just think about there being still fortran or assembly code

                  Probably nothing, I have never tried it… but docker compose feels so comfortable right now and relearn everything… uuhhg !

        Depends on how much you value your time.

        Compare a few hours on bare metal to a few minutes with containers. Then consider that you also spend extra time on bare metal cleaning up messes. Containers don’t make a mess in the first place.
