Running a Kubernetes Application
Chapter 4 ■ Using Multiple Zones
Next, we shall test the Kubernetes cluster to confirm that pods in an application do get allocated across the
nodes in the different zones. Connect to the controller instance:
ssh -i "kubernetes-coreos.pem" core@52.202.134.20
The controller instance is logged into as shown in Figure 4-15.

Install the kubectl binaries and set permissions.
sudo wget https://storage.googleapis.com/kubernetes-release/release/v1.3.0/bin/linux/
amd64/./kubectl
sudo chmod +x ./kubectl
Kubectl binaries are installed. Move the kubectl binaries to /usr/local/bin/, which is in the path:
sudo mv ./kubectl /usr/local/bin/
List the nodes in the cluster:
./kubectl get nodes
The single master node and the six worker nodes are listed as shown in Figure 4-16.
