Chapter 4 ■ Using Multiple Zones
Run the nginx Docker image to create six pod replicas:
kubectl run nginx --image=nginx --replicas=6 --port=80
Subsequently, list the pods:
kubectl get pods –o wide
The nginx deployment is created and the pods are listed. Initially the pods may be listed as not ready, as
indicated by the READY column value of 0/1 and STATUS column value of ContainerCreating in Figure 4-17.
Figure 4-17. Running the Kubernetes nginx application
Run the kubectl get pods –o wide command again after a few more seconds (up to a minute) and
all the pods should be running and ready as shown in Figure 4-18. As indicated in the NODE column, each
of the six pods is running on a different node, which implies that the pods are spread across the zones in the
cluster. A failure of a single zone will not affect the availability of the deployment.
