This is the case even with "update-crypto-policies -set DEFAULT". However, the website also uses an SSL encryption not supported by RHEL 8.0, and requiring extensive "dnf update" commands to enable. So, we will install the latest Docker here by using Docker’s official repositories. Docker packages are available under the Red Hat repositories, but it may not have the latest version.
It's not the first time they've done this, they do it with sssd versus the upstream published, upen source Samba software. If you are using RHEL 8 or CentOS 8, install Docker version 20.10.7 or later: Add the Docker repository: Add yum config manager sudo yum install -y. In this tutorial, you will learn to install Docker on an RHEL 8 Linux system. 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. If you use CentOS 8/RHEL 8 server edition, you need to run the following. 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. However docker-cups-airprint has 1 bugs and it build file is not available. After installing the packages, start the Podman systemd socket-activated service using the following command: sudo systemctl start podman. The title should be refined to "Unable to install docker-ce on RHEL 8". Other than Podman and its dependencies, be sure the podman-docker and docker-compose packages are installed.
