Kubernetes Cookbook - Second Edition

How to do it...

In this recipe, we'll use localhost cluster as the main console to switch the cluster via context changes. First, run a different number of nginx into both the clusters and make sure the pods are all running:

// in the terminal of localhost cluster$ kubectl run local-nginx --image=nginx --replicas=2 --port=80deployment "local-nginx" created// check the running pods$ kubectl get podNAME                           READY     STATUS    RESTARTS   AGElocal-nginx-6484bbb57d-xpjp2   1/1       Running   0          1mlocal-nginx-6484bbb57d-z4qgp   1/1       Running   0          1m// in the terminal of remote cluster$ kubectl run remote-nginx --image=nginx --replicas=4 --port=80deployment "remote-nginx" created$ kubectl get podNAME                            READY     STATUS    RESTARTS   AGEremote-nginx-5dd7b9cb7d-fxr9m   1/1       Running   0          29s
