Developing with Docker also speeds up applications because it shares the kernel and other Linux resources. This is the case even with "update-crypto-policies -set DEFAULT".Docker is a platform that makes it easy to build, deploy and start applications using containers. 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. The title should be refined to "Unable to install docker-ce on RHEL 8".
