To get a listing of all of the nodes in a cluster and the status of each node, use the kubectl get command. This command can be used to obtain listings of any kind of resource that Kubernetes supports. In this case, the nodes resource:

$ kubectl get nodes
NAME                   STATUS    ROLES   AGE      VERSION
master.example.com     Ready     master  1h       v1.17.x+x.x.x.el7
worker1.example.com    Ready     <none>  1h       v1.17.x+x.x.x.el7
worker2.example.com    Ready     <none>  1h       v1.17.x+x.x.x.el7

You can get more detailed information about any resource using the kubectl describe command. If you specify the name of the resource, the output is limited to information about that resource alone; otherwise, full details of all resources are also printed to screen:

$ kubectl describe nodes worker1.example.com
Name:               worker1.example.com1
Roles:              <none>
