  Just use podman, easy migration from docker.

    Yes, until it’s NOT. Running RHEL 9 with docker engine slapped in there because the BitBucket self-hosted containerized runner is incompatible with podman.

      Last time I tried to migrate to Podman the first container I tried was incompatible, so was the second, and the third. Turns out at the time Linuxservers.io stuff wasn’t rootless podman compatible. There have since been some improvement according to my most recent Google search just now, so maybe a retry is coming up.

    podman is not a replacement to docker.

    I fucking hate how the podman docs say that(because ofc they do).

    it’s like saying c++ is a replacement to c. can they work, sure. are they the same? you try importing libs into c the same way you do in c++ and find out. yeah, they’re both c under the covers but they are not the same.

    It’s definitely not an easy migration in my experience, because they run rootless and they cannot auto-start without making a system service for every stack, there is a lot that needs to change in a compose stack, especially with file permissions for shared mounts.

      Agreed. Setting up an NFS share is a mess with Podman

    Yes, I already moved everything and works perfectly… except… nextcloud…

    I am trying to setup a new one but too much debugging the last 10 hours

      Which tutorial did you follow?

      How is your selinux setup?

  So containers have been standardized for a while now (OCI), and even if you install “docker” it’s actually just installing containerd with docker-cli. For years kubernetes is not even supporting docker-shim anymore. So there should be no issue. What is even the problem you are running into?

  Oh, I see that RHEL has officially dropped docker support. You can try installing from binaries, but you are definitely striking out on your own here.

  I don’t mean to rake you over the coals here, but what is the reasoning for sticking with RHEL for this project? If you are attempting to use it in an paid enterprise situation, you are better off sticking with items on the compatibility list. If you run into issues with other supported services, the first piece of advice will be to remove docker. Since your are not getting support for docker, I would advise running it from a supported OS.

    Well, as I am running my personal server for years, I wanted to test/understand more enterprise solutions except Debian/Ubuntu and especially solutions with SELinux. In the end if I face major issues I will setup Nextcloud to a VM. Thank you for your response

      No shame in testing out enterprise solutions. Best of luck in your endeavor.

      If you’ve been running these “for years”, you certainly should know the pitfalls of switching to a brand new distro. Like the exact situation you’re asking about.

      You should also know that packages tagged as compatible with another version of any distro won’t harm your current one to just install and find out if it works.

      As many other commenters are saying, we don’t know what your problem is, or why you’re here.

  hasn’t been available since like 8. right?

  IBM bought redhat, negotiations with docker bottomed out because docker wouldn’t appease IBM execs, and IBM used their competitor podman. IBM yanked docker out of all packages almost overnight.

  yet another reason why I left redhat. any company that uses their power for the sake of using it makes running business on their platform hard, but that’s kind of IBM’s whole schtick.

  I actually have a solution for your problem. Change distros:

  search.nixos.org/packages?channel=25.05&from=0&si…

  all kinds of docker versions and you don’t have to do any manual steps

  Reading the Docs, it seems like PodMan is the replacement for docker. You could try containerd/nerdctl, but podman is likely the best way for you. RHEL10 docs even say it supports the older docker config options

  source

  • GreenKnight23@lemmy.world ⁨3⁩ ⁨days⁩ ago

    podman is not a drop-in for docker.

    they lie and anyone saying otherwise is lying too.

    source

    • possiblylinux127@lemmy.zip ⁨2⁩ ⁨days⁩ ago

      It depends on what you are trying to do. Podman has a different design but it has pretty solid compatibility with docker. It also supports OCI containers so from the applications perspective it looks the same.

  docs.docker.com/engine/install/rhel/

  You should be able to add the repo and install the packages anyway. If it doesn’t work, give a description of the behavior including errors or logs.

  source

  • sv1sjp@lemmy.world ⁨3⁩ ⁨days⁩ ago

    Yes, I have already read that and it clearly says:

    To install Docker Engine, you need a maintained version of one of the following RHEL versions:
    
    RHEL 8
    RHEL 9
    

    source

    • ilmagico@lemmy.world ⁨3⁩ ⁨days⁩ ago

      I guess what they’re saying is, even though it’s “not supported” officially, you can still try and there’s good chances it’ll work anyway. If you need or prefer to stick to a supported configuration, it seems your options are either to switch to podman and figure out nextcloud, or switch away from RHEL.

      I don’t know why people ask for help and refuse to listen when it’s given.

  Nextcloud is in EPEL 10. You’ll get updates along with the rest of the OS.

  I have been using EPEL 9 Nextcloud for a good while and it’s been a smooth experience.

  If you want specifically Docker, I would not choose an EL10 distro, really. I have been test driving AlmaLinux 10 and it’s pretty nice, but I would look elsewhere.

  Just uninstall podman and install docker-ce. Official docker docs have steps even.

  source

  • sv1sjp@lemmy.world ⁨3⁩ ⁨days⁩ ago

    It is not available for RHEL 10.

    source

    • just_another_person@lemmy.world ⁨3⁩ ⁨days⁩ ago

      🤦

      So do like I said and visit the Docker official docs, setup the RHEL repos, and install it. Or, you can just install the ROM packages individually. OR you can wait a few weeks until the official packages show up which will ease the the same thing.

      Your choice.
