Kubernetes Cookbook - Second Edition

Command-line interface (kubectl)

After you install the Kubernetes master, you can use the Kubernetes command-line interface, kubectl, to control the Kubernetes cluster. For example, kubectl get cs returns the status of each component. Also, kubectl get nodes returns a list of Kubernetes nodes:

//see the Component Statuses# kubectl get csNAME                 STATUS    MESSAGE              ERRORcontroller-manager   Healthy   ok                   nilscheduler            Healthy   ok                   niletcd-0               Healthy   {"health": "true"}   nil//see the nodes# kubectl get nodesNAME          LABELS                           STATUS    AGEkub-node1   kubernetes.io/hostname=kub-node1   Ready     26dkub-node2   kubernetes.io/hostname=kub-node2   Ready     26d
