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.

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.

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?

Just use podman, easy migration from docker.

[–] [email protected] 3 points 6 hours ago

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.

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.

[–] [email protected] 19 points 1 day ago (1 children)

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.

[–] [email protected] 19 points 1 day ago (1 children)

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.

[–] [email protected] 10 points 1 day ago (1 children)

You can run it rootful, then it behaves just like Docker.

[–] [email protected] 3 points 21 hours ago (1 children)

Doesn't that break the whole purpose of podman (rootless containers)?

[–] [email protected] 6 points 20 hours ago

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.

[–] [email protected] 5 points 1 day ago (2 children)

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

[–] [email protected] 1 points 1 day ago

Which tutorial did you follow?

How is your selinux setup?

[–] [email protected] 10 points 1 day ago (1 children)

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.

[–] [email protected] 5 points 1 day ago (3 children)

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

[–] [email protected] 1 points 3 hours ago

SElinux will run on any system with Linux

[–] [email protected] 9 points 1 day ago

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

[–] [email protected] 3 points 21 hours ago

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.

[–] [email protected] 7 points 1 day ago

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

https://search.nixos.org/packages?channel=25.05&from=0&size=50&sort=relevance&type=packages&query=docker

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

[–] [email protected] 6 points 1 day ago (2 children)

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

[–] [email protected] 3 points 18 hours ago (1 children)

podman is not a drop-in for docker.

they lie and anyone saying otherwise is lying too.

[–] [email protected] 1 points 3 hours 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.

[–] [email protected] 2 points 21 hours ago (1 children)

BUT THATS NOT WHAT I LIKE TO UUUSSSEEEEE WAAAAHHHHHHHH 😭😭😭😭😭😭😭😭😭

[–] [email protected] 6 points 21 hours ago (3 children)

What the fuck is your problem? :D

[–] [email protected] 1 points 3 hours ago

They are just another person

[–] [email protected] 1 points 18 hours ago

poor impulse control.

that or they use podman over docker.

[–] [email protected] 1 points 20 hours ago* (last edited 20 hours ago)

Just empathetic. Is that bad now?

[–] [email protected] 6 points 1 day ago (1 children)

https://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.

[–] [email protected] 8 points 1 day ago (2 children)

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
[–] [email protected] 6 points 1 day ago (1 children)

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.

[–] [email protected] 2 points 7 hours ago

It won't work since there's no RHEL10 repo. You can however use CentOS (Stream) 10 repo, I use it that way and it works!

[–] [email protected] 6 points 1 day ago (1 children)

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

[–] [email protected] 1 points 1 day ago

Exactly. Getting downvoted by plebs because of this.

[–] [email protected] 4 points 1 day ago

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.

[–] [email protected] 2 points 1 day ago (1 children)

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

[–] [email protected] 9 points 1 day ago (1 children)

It is not available for RHEL 10.

[–] [email protected] 4 points 1 day ago (1 children)

🤦

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.

[–] [email protected] 11 points 1 day ago (1 children)

😊

The official docs:

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

RHEL 8
RHEL 9
[–] [email protected] 5 points 1 day ago* (last edited 1 day ago) (1 children)

Man, 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.

[–] [email protected] 10 points 1 day ago (2 children)

The main point was about that Docker is not available for now in RHEL10. Chill

[–] [email protected] 5 points 1 day ago (1 children)

When people like you stopping coming in here with useless comments and complaints, I'll stop responding to them. 🫰
