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 nodes
NAME      STATUS  ROLES   AGE   VERSION
minikube   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 namespaces
NAME          STATUS   AGE
default       Active   15h
kube-public   Active   15h
kube-system   Active   15h

It says No resources found, all because the pod is a Kubernetes resource, similar to other resources we are going to cover in this book.
