Each tool in this scenario is more lightweight and focused on a subset of features.įor my latest work project, however, where we will be deploying Kubernetes clusters with Rancher we need RHEL8 and Docker. The Podman, Skopeo, and Buildah tools were developed to replace Docker command features. It looked like that URL wanted 7Server instead of 7 as the releasever variable.As per Red Hat documentation Docker is not supported in RHEL 8. When I ran the install command again, it found the repository correctly!īut then it needed to load another URL that broke. I was able to add a file called releasever to /etc/yum/vars with the value of 7 in it. Still stuck on how to get this to download and install docker.
The 7 value I was looking for was not substituted in there. I added a line like this: distroverpkg=7.īut when I ran the install command again, 7Server was replaced by $releasever directly (no substitution happened). This page indicates that $releasever is read from /etc/yum.conf in the setting distroverpkg.
I am open to any advice on how to get this working.Įxploring a bit more I found that this URL is probably the one I need to use:īut I don't know how to get it to use that.ĭownloading the file at (from the first command) showed that it was getting the 7Server value from a yum variable called $releasever. But I am unsure on what the correct URL should be and what to do to get it to use the correct URL. When I do that I get the following error: Then install by running: sudo yum install docker-ce docker-ce-cli containerd.io It says to setup a repository by calling: sudo yum-config-manager -add-repo
