No, installing OpenShift Container Platform 4.6 on this particular VM is not possible for multiple reasons:

  • In any case, the Control Plane requires Red Hat CoreOS as its Operating System.

  • The smallest possible OCP cluster is a Three-Node OpenShift Compact Cluster, where Control Plane nodes are also used to schedule workload. A single-node cluster installation does not exist at this time (apart from CodeReady Containers, which you do not want to use).

  • Even with the small cluster above, you are looking at at least 3x 24GB of RAM as the minimum requirement. VMs with less RAM might work, but the cluster will likely be unstable.

With limited resources, the only way to run OpenShift 4 is to use CodeReady Containers.
