Absolutely helpful. Followed it blindly and worked like a charm.

In reply to Pradeep Kumar. Absolutely, you must first remove buildah and podman, before the step 1: sudo dnf remove podman buidah -y

Hello Ibrahim,

Above steps are still valid for CentOS 8 & RHEL 8. I have tested on CentOS 8 system, it is working as expected. I would suggest first remove the docker repository that you have configured and also remove podman and docker ( older version) in case it is installed.

Update the system and then try these steps.

you have to add on last step to be able to check the command “docker-compose –version” :

ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

In reply to Gunnar Thielebein. Man, thanks. Just don't copy these commands since minus signs got replaced into dashes!

If you disable CentOS' container-tools module you can install the latest Docker CE using docker-ce.repo, that is no more --nobest necessary: dnf module disable container-tools dnf install docker-ce docker-ce-selinux
