-A convenience script to generate a manifest for running CoreDNS on a cluster that is currently
-running standard kube-dns. It creates a ConfigMap and a CoreDNS deployment, then updates the
-Kube-DNS service selector to use the CoreDNS deployment. It doesn't delete the kube-dns
-deployment or replication controller - you'll have to do that manually.

+to deploy CoreDNS in Kubernetes.
