In 2.1. Installing the AMQ Broker on OpenShift Container Platform image streams and application templates we use '-n openshift' for all create commands. The -n specifies the namespace to operate on, and in this case the openshift namespace is the target.

It is important to NOTE that the openshift namespace is a system level namespace, meaning that it requires cluster-admin permissions that most developers won't have. We should also tell them that they can use '-n my_own_project _namespace_name' to import the image stream and templates directly into their own namespace which does NOT require cluster-admin level permissions to achieve.
