3. Next, select "Authorized Endpoint."
4. Before moving forward, you must connect to your Kubernetes master node.
5. From there, you will have to cd into /etc/kubernetes/ssl, copy kube-ca.pem file, navigate to the Rancher UI, and paste in the CA Certificate field.
6. Next, verify the kube-ca.pem file.
7. We won't be able to see the Network Load Balancer address

8. Run this command to get the contents of your certificate:

   • Then click save
   • Next, verify the kube-ca.pem file.
   • Next, copy the ./kube/config file in the Rancher UI.
