2.1.1 - Verify the cluster is running

Hopefully by now the Kubernetes cluster has had enough time to start. Now we need to quickly test that everything is up and running.

  1. In the terminal, change to the section2 directory: cd ~/environment/section2.

  2. Run kops validate cluster. You should see something like this.validate cluster

  3. Run kubectl get pods -n kube-system and hopefully you will see something like this:

What you are looking for is a list of pods that have a status. Running is best, but any status shows us that the Kubernetes cluster is at least running.
