Default Storage Class via Local Path
Add Extra Drive e.g. sdc for your nodes, you can skip if you don't need default storage class from local path

Installation
Setup Env variables Very Important
- Setup Enviroment Variables

Delete Don't manual delete one by one if you want to restart
$ kfctl Delete -V -f ${CONFIG_URI}- Wipe out Rancher : https://rancher.com/docs/rancher/v2.x/en/cluster-admin/cleaning-cluster-nodes/
- Before you re-ininstall please wipe out

Login Kubeflow
Under Rancher, it's pretty straightforward. Just go to Project's Resource -->
