Can't retrieve Docker Info: error during connect:

Rancher
1

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.

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