containerd.io is required for docker howerver it is not avilable in official yum repos. It needs to be installed directly from docker. ref: https://docs.docker.com/install/linux/docker-ce/centos/ https://linuxconfig.org/how-to-install-docker-in-rhel-8

Could probably also provide a link to an article that instructs a user how to get around this. Or could suggest they do something like use the podman provisioner #11464

Borrowing from the get.docker.com script slightly, I think we could say something like:
RHEL is now only supported by Docker EE. Please install Docker EE or switch to the Podman provisioner to run containers on RHEL.
Does this apply to RHEL < 8 as well?

Nice, ya that sounds better!
As far as I can tell, docker isn't supported on RHEL at all. Though the docker docs still have a guide for installing docker ce that works up until (and including) RHEL 7 https://docs.docker.com/install/linux/docker-ce/centos/#install-docker-engine---community.
Maybe the warning should be emitted for all RHEL systems and only hard fail on RHEL 8?

I feel like Vagrant should not attempt to install Docker on RHEL:
- The docker-install script says it's not supported: https://github.com/docker/docker-install/blob/b50fac9805c3d95fb5e8b16d57b19d333e972e20/install.sh#L318
- Docker Engine - Community is not supported on Red Hat Enterprise Linux.
Folks who want to use Docker on RHEL can still install it themselves using a shell provisioner, since this seems to be pretty well documented.
This approach will be more stable than depending on a convenience script provided by docker ref: https://docs.docker.com/install/linux/docker-ce/ubuntu/#install-using-the-convenience-script
