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.

You can run docker rootless https://docs.docker.com/engine/security/rootless/ but you have to switch to podman some day anyway, althiugh that might be in a far away future.

If you are concerned about root you may be concerned about the docker port dilemma as well, podman solves that as well

but you have to switch to podman some day anyway

Can you elaborate on this?

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 !

[–] beta_tester@lemmy.ml 1 points 9 months ago (1 children)

What's wrong with podman?

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

[–] N0x0n@lemmy.ml 1 points 9 months ago (1 children)

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

I had to add :Z to the paths in the docker compose files for selinux.
