As I can see, Docker is not available in RHEL10 (at least for now).
Yes, I know, podman is an option, I already converted all of my services, but for my nextcloud setup… I find it impossible to make it full functional in podman…
Edit: Okay I succeeded, thank you for your messages, I know how to manually install rpms, the main point was to discuss that Docker is not available in RHEL.
You must log in or # to comment.
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.
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?
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.
edit: why the downvotes? this is literally what happened. docker said they couldn’t delivered rootless when IBM wanted it because they had other priorities. IBM said fuck you we’re dropping support for podman. docker said ok, and now we have a podman still masquerading like a drop in replacement.
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.
You can run it rootful, then it behaves just like Docker.
Doesn’t that break the whole purpose of podman (rootless containers)?
A little but there is also systemd integration with podman.
However for that I usually set up a lingering user with limited permissions. For some cases you need rootful though.
I actually have a solution for your problem. Change distros:
all kinds of docker versions and you don’t have to do any manual steps
Just uninstall podman and install docker-ce. Official docker docs have steps even.
It is not available for RHEL 10.
🤦
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.
😊
The official docs:
To install Docker Engine, you need a maintained version of one of the following RHEL versions: RHEL 8 RHEL 9Man, if you’re this green, just go back to RHEL 9 until they come back and tell you it’s okay to do exactly as they say. Did you just come here to complain, or do you honestly not know how this all works?
Literally download the RPMs like I said if you don’t know how to use backref repos.
