Running a single node OpenShift cluster is very easy with oc cluster up.
It's also very easy to run it as system service with persistent configuration, so that on system boot the simple single-node OpenShift cluster starts using the configuration saved. Just put the following Systemd unit under /etc/systemd/system/openshift.service and enable / start it.
