Hi Team,  
I have been following the instructions of the rancher academy for lab 2 (Setting up the rke up )

#Note:  
I’m using Azure Linux VM (running on ubuntu 16.04). So on vm under /home/rkeuser/.ssh I have only "authorized\_keys ", There is no “id\_rsa”.  
For rke config do I need a new ssh key to generate? I running a single node cluster with  
role:

- controlplane
- worker
- etcd

Please suggest to me here.

I have followed the video instructions as well. But still getting below error.

Below is cluster.yml

If you intened to deploy Kubernetes in an air-gapped environment,  
please consult the documentation on how to configure custom RKE images.
