I would like to be able to add support for CentOS 9 Stream at https://download.docker.com/linux/centos/ .

Which service(s) is this request for?
Let us know which product(s) you want this for?

docker-ce

Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?
A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

When I try to install docker-ce on CentOS 9 Stream, it reports 404, this is because there is no such version of $releasever as 9 in the corresponding repo.
I have tried commands like the right to specify the repo on CentOS 8 Stream, and I used the --nobest parameter of yum to keep the program running (yes, even on Centos 9 Stream, yum keyword is still preserved), i.e. sed -i 's/$releasever/8/g' /etc/yum.repos.d/docker-ce.repo.
This was followed by a tentative sudo yum install --nobest docker-ce docker-ce-cli containerd.io step, which unfortunately failed (please ignore the Chinese, in fact I'm not sure of its English counterpart, So I didn't do the translation)

[root@localhost ~]# sudo yum install --nobest  docker-ce docker-ce-cli containerd.io

(尝试添加 '--skip-broken' 来跳过无法安装的软件包)

I then tried yum install libcgroup, and the result was that match failed. Apparently the libcgroup package is an outdated component on RHEL and CentOS.

Are you currently working around the issue?
A clear and concise description of any alternative solutions or features you've considered or are using today.

Honestly I don't know how to fix it, it looks like Docker depends on libcgroup. I linked from another post. docker/docs#13792

Additional context
Add any other context or screenshots about the feature request here.

Based on using centos 8-strem's repo, e.g.

curl https://download.docker.com/linux/centos/docker-ce.repo -o /etc/yum.repos.d/docker-ce.repo
sed -i 's/$releasever/8/g' /etc/yum.repos.d/docker-ce.repo
dnf install docker-ce -y # error, reporting ' nothing provides libcgroup needed by docker-ce-3:20.10.12-3.el8.x86_64'

As there is no libcgroup in centos 9-stream's repo, uses the pkg in centos 8-stream's repo instead for now.

dnf install wget -y
wget http://mirror.centos.org/centos/8-stream/BaseOS/x86_64/os/Packages/libcgroup-0.41-19.el8.x86_64.rpm # download into current directory
dnf install libcgroup-0.41-19.el8.x86_64.rpm -y # install the package
dnf install docker-ce -y # now, it won't report lack of the dependecy  `libcgroup` 

systemctl enable --now docker

After install::

[root@localhost ~]# cat /etc/centos-release # just show my os version

@EeeMt Thanks for your answer!

Although the documentation for Centos 9 Stream is not yet finished (as stated in https://lists.centos.org/pipermail/centos-devel/2021-November/077450.html), I noticed that due to Centos 9 Stream As upstream of RHEL 9, RHEL 9 documentation has a note on this. https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9-beta/html/considerations_in_adopting_rhel_9/assembly_changes-to-packages_considerations-in-adopting-rhel-9#removed-packages_assembly_changes-to-packages mentions that libcgroup as part of Removed packages no longer exists.

Maybe docker-ce should remove the reference to dependency of libcgroup ?

The documentation for this component has been marked as obsolete as of RHEL 7 at the latest (as stated in https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/resource_management_guide/chap-using_libcgroup_tools ).

[fansari]

I have the same issue. But this installation of libcgroup and usage of CentOS 8 repo is only a temporary solution, right?

If anyone on the official panel can reply, this is clearly not the correct way to install it - it has been noticed but doesn't seem to have gone any further. At least containerd.io has an RPM package for RHEL 9 and is available on CentOS 9 Stream.

[linsalrob]

The fix described here did not work for me on a fresh CentOS 9 Stream install:

[root@localhost ~]# cat /etc/centos-release # just show my os version
CentOS Stream release 9

Follow all the steps described by @EeeMt until the last step:

The --nobest does not solve this issue either.

[linsalrob]

Following the instructions at nvidia for installing docker on CentOS 8:

Since CentOS does not support specific versions of containerd.io packages that are required for newer versions of Docker-CE, one option is to manually install the containerd.io package and then proceed to install the docker-ce packages.

sudo dnf install -y https://download.docker.com/linux/centos/7/x86_64/stable/Packages/containerd.io-1.4.3-3.1.el7.x86_64.rpm
sudo dnf install docker-ce -y

And then check the version.

You may also have to remove buildah and podman before using docker-ce to resolve the runc conflict.

dnf remove buildah podman

[linghengqian]

You may also have to remove buildah and podman before using docker-ce to resolve the runc conflict.

In my previous tests, buildah and Podman were not installed if the minimum installation mode was selected when initializing CentOS 9 Stream, perhaps something has changed in later versions.

I have the same issue.

You are correct, it depends what installation options are selected. I did not select minimum installation because I need other things!

[linsalrob]

I have the same issue.

Unfortunately, at the moment, my solution was to downgrade to CentOS Stream 8.

[jrgruher]

I am also unable to install Docker on CentOS Stream 9. Would love to be able to!
