Refer to the upstream project's official documentation for the various pre-requisites. You must have an IAM role with the right permissions attached to your K3s instances, and you must also tag your nodes with a clusterid. Refer to the Rancher documentation for how to do this

curl -sfL https://get.k3s.io | INSTALL_K3S_EXEC="server \

We can start with:

kubectl get no

Had to add: 
  -e CHE_KEYCLOAK_AUTH-SERVER-URL=192.168.0.143:5050/auth
  
  notice the key format (dashes instead of underscores)
  
  This is likely to be fixed (should be underscores for consistency).

Obvious to try after getting error message below:
