Provide Docker Engine CE Offline RPM for CentOS 8

[johnthagen]

Problem description

Currently if a user wants to get an offline RPM installer for CentOS, they are told:

To install Docker Engine - Community, you need a maintained version of CentOS 7

But the latest CentOS version is CentOS 8. For users that need an offline RPM installer of Docker Engine CE for CentOS 8, there is currently no documented way to do this.

Problem location

• I saw a problem on the following URL: https://docs.docker.com/install/linux/docker-ce/centos/#os-requirements

• I couldn't find the information I wanted. I expected to find it near the following URL: https://docs.docker.com/install/linux/docker-ce/centos/#install-from-a-package

Suggestions for a fix

Provide official CentOS 8 compatible RPM installers for docker-ce and documentation that tells users how to download and install them.

I would expect them to be hosted at a URL similar to: https://download.docker.com/linux/centos/8/x86_64/stable/Packages/

It's time to support CentOS 8.

+1, CentOS 8 is stable since September 2019, its time to support it.
There are workarounds like this for the installation at CentOS8: docker/for-linux#873 (comment)

But be aware that with this method the containerd.io rpm did not get any updates via yum/dnf, which is a security issue.

Unfortunately it looks like Red Hat cancelled the CentOS Linux project: https://blog.centos.org/2020/12/future-is-centos-stream/

CentOS 8 support ends in 2021. 😞

Probably the best course of action now would be for Docker to provide offline RPMs for Rocky Linux 8, the community successor to CentOS.

Actually, after checking it appears that CentOS 8 RPMs have been published: https://download.docker.com/linux/centos/8/

Ah, yes, packages for centos 8 have been available for some time now. Let me close this ticket
