To verify use either of the below commands. The kernel should have a storage backend such as DeviceMapper. To check the kernel version, run the following command: uname -r 3.10.0-693.5.2.el7.x8664. Docker is supported on kernel version 3.8 or later.

This is the case even with 'update-crypto-policies -set DEFAULT'. To check the architecture use the below command. However, the website also uses an SSL encryption not supported by RHEL 8.0, and requiring extensive 'dnf update' commands to enable. It's not the first time they've done this, they do it with sssd versus the upstream published, upen source Samba software. Many vendors still rely on docker-ce and have not updated to podman, leaving RHEL 8 maintainers with some very awkward choices about compliance with their vendor's installation instructions and Red Hat's corporate support for podman instead. It's true that the published 'docker-ce.repo' file does not work for RHEL 8, and needs to be edited to point to CentOS for access. There is a package called 'docker' available on RHEL 8, apparently podman based, but quite distinct frm the open source 'docker-ce' package from upstream. Install docker-ce with the -nobest option. The title should be refined to 'Unable to install docker-ce on RHEL 8'. Install Docker CE and Docker compose on RHEL 8 Add the external repository by running the following command.

Yum install docker rhel
