Because, for now, it is just for test purposes, the Atomic servers are virtualized in an OpenStack cluster. I successfully installed Atomic and Cockpit using the online documentation. I was able to test that there is no new distribution available through both Cockpit and the command line using the “atomic” command”.

I successfully pulled the images for kubernetes for both the master and the node (even if for the node, the f28/kubernetes-proxy, does not exist). But, when I try to install kubeadm using rpm-ostree, I got the following error:

I just tested "rpm-ostree install kubernetes-kubeadm -r" on a fedora
atomic 28 VM and it worked. Maybe it was some sort of intermittent
network issue? This may help w/ kubeadm:

If you're using kubeadm, you don't need to install the system
containers, but I'll look into what's up with that proxy system
container.
