Kube DNS example doesn't work as described using OpenShift Playground

[jdandrea]

"[OpenShift Playground] is the option we used for most of the examples on the site." But I'm unsure if the Playground comes with Kube DNS. (There may not be anything we can do, but I figure it doesn't hurt to capture here.)

Correction: Kube DNS appears to be there, but the host is unreachable.

$ kubectl get svc
