Configure a Kubernetes client on **worker node 3

I am trying to do the following project , but I am unable to  figure out how to " Configure a Kubernetes client on **worker node 3** " . Kindly guide me .

As an infrastructure admin, you need to take the backup of an etcd in a file called /tmp/myback. Make sure to have a namespace called cep-project2 with a network policy configured in such a way that all the Pods in the same namespace should access each other. Any other Pods from the non cep-project2 should not access the Pods. **Configure a Kubernetes client on worker node 3** in such a way that user4 should have only view access to cep-project2. Update the master with the latest version of the Kubernetes`Preformatted text`

OK, this is not readable… let me see if I can get something I can read:

To be honest, I don’t understand the question either. But “a kubernetes client” would be installing kubectl and setting up an appropriate kubeconfig file that defines a user with the requested permissions and limitation.

Sir , I am pasting the exact text of the task .

Following is the task given : Backing up the Etcd Cluster Data

Queastion : How to Configure a Kubernetes client on worker node 3 in such a way that user4 should have only view access to cep-project2 ?

Does it mean creating a new user - user4. if so can it be created on Node-3 ?
