 First, note the service that exposes RGW internal to the cluster. We will leave this service intact and create a new service for external access.

 If you're testing on the [coreos-kubernetes vagrant environment](k8s-pre-reqs.md#new-local-kubernetes-cluster), you can verify it is working from your host:
 - If running in the single-node cluster:
-  - `curl 172.17.4.99:30711`
