With the latest kubernetes code pulled from github today.

Steps: Run docs/getting-started-guides/docker-multinode/master.sh on one Ubuntu server called dpcdd3. Alternatively, here is the URL:

https://github.com/kubernetes/kubernetes/blob/master/docs/getting-started-guides/docker-multinode/master.sh

# kubectl get no
NAME      LABELS                          STATUS    AGE
dpcdd3    kubernetes.io/hostname=dpcdd3   Ready     1h

(note: worker.sh is not invoked just yet on second server).

On an older code (selected randomly from approx a month ago), the same command, in identical setup: 'kubectl get no' would give back nothing.

Here are some current run-time details:

# kubectl version
Client Version: version.Info{Major:"1", Minor:"2+", GitVersion:"v1.2.0-alpha.6.239+a5d2c1b0fb23a1", GitCommit:"a5d2c1b0fb23a145c47935f041a036d8546cd01f", GitTreeState:"clean"}
Server Version: version.Info{Major:"1", Minor:"1", GitVersion:"v1.1.3", GitCommit:"6a81b50c7e97bbe0ade075de55ab4fa34f049dc2", GitTreeState:"clean"}

Interestingly, the pods are shown with status: 'pending':

# kubectl get po
NAME                READY     STATUS    RESTARTS   AGE
k8s-master-dpcdd3   0/3       Pending   0          1h
