And there is a [management console|https://10.0.0.164:8443/console] available.
You first create a project :
{{{
openshift ex new-project proj2 --description="test desc 2" --display-name="displee naam 2" --admin=admin
}}}
Install the stuff on another Centos7 virtualbox image, see OpenShift [Setup details|http://docs.openshift.org/latest/getting_started/setup.html] and [Installation|http://docs.openshift.org/latest/getting_started/installation.html].
