Today: How to limit users ability to create projects in OpenShift Container Platform 3.4.

1. Add Example 2 found here: https://docs.openshift.com/container-platform/3.4/admin_guide/managing_projects.html#limit-projects-per-user to the top of your /etc/origin/master/master-config.yaml file.

2. Add fitting labels to the different users like such:
$ oc label user/admin level=admin
$ oc label user/user1 level=silver
$ oc label user/user2 level=gold

3. For a single master cluster, restart ‘atomic-openshift-master’ and for a HA (3-5) master cluster, restart ‘atomic-openshift-master-api atomic-openshift-master-controllers’ on all masters.

4. Done!
