Jared,
Openshift exposes the ExternalIP and you have to associate it with a NIC
to use it. We usually do this by making it a VIP in a high availability
configuration. You also need to route to the node.
Something like:
ip addr add 10.252.0.28/24 dev em2
on one of the nodes in the cluster should work.
The following my help as well:

Hi guys,
I deployed redis with replication controller successfully on openshift
origin cluster.
Then I tried to create service for external clients to connect.
However, it seemed that it didn't work.
How could I debug similar problem? Is there any guidance about using
externalIP in openshift?
The detailed information is as below,
/[root@host-10-1-236-92 gluster]# oc get svc
