Frank Messier 3f90202f03 Amend output of the get pods command
Still somewhat of a k8s n00b, so sorry if I'm out of line here, but I'd like to propose a small amendment to the output of the get pods command confirming the deployment of the kube-dns add-on. 

This seems like a deployment creating a single replicaset by default, the output should then list a single RS.

From the deployment's YAML file:
spec:
  # replicas: not specified here:
  # 1. In order to make Addon Manager do not reconcile this replicas parameter.
  # 2. Default is 1.
  # 3. Will be tuned in real time if DNS horizontal auto-scaling is turned on.

Output of a describe of the resulting deployment:

kubectl describe deployment kube-dns -n kube-system | grep ReplicaSet
OldReplicaSets:  <none>
NewReplicaSet:   kube-dns-6c857864fb (1/1 replicas created)
