Your Kubernetes master has initialized successfully!
To start using your cluster, you need to run (as a regular user):
You should now deploy a pod network to the cluster. Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at: http://kubernetes.io/docs/admin/addons/
You can now join any number of machines by running the following on each node as root:
$ kubectl get nodes NAME STATUS ROLES AGE VERSION k8s-master Ready master 7m v1.8.4 k8s-node-1 Ready <none> 22s v1.8.4 k8s-node-2 Ready <none> 15s v1.8.4
