Using the kubectl get command

The first essential command to run is kubectl get nodes. It gives us the number of Kubernetes nodes available:

$ kubectl get nodesNAME      STATUS  ROLES   AGE   VERSIONminikube   Ready   <none> 2h    v1.9.0

In our case, the number of nodes will be equal to one, since we are using one VM for our practice. As we mentioned already, in order for different projects to coexist on the same or different nodes, namespaces are used. You may guess that the command we should use is kubectl get namespaces:

$ kubectl get namespacesNAME          STATUS   AGEdefault       Active   15hkube-public   Active   15hkube-system   Active   15h

It shows you that three default namespaces are available when you install Kubernetes with Minikube:
