* Configuring local host environment ...
*
! The 'none' driver is designed for experts who need to integrate with an existing VM
* Most users should use the newer 'docker' driver instead, which does not require root!
* For more information, see: https://minikube.sigs.k8s.io/docs/reference/drivers/none/
*
! kubectl and minikube configuration will be stored in /root
! To use kubectl or minikube commands as your own user, you may need to relocate them. For example, to overwrite your own settings, run:
*
- sudo mv /root/.kube /root/.minikube $HOME
- sudo chown -R $USER $HOME/.kube $HOME/.minikube
*
* This can also be done automatically by setting the env var CHANGE_MINIKUBE_NONE_USER=true
* Verifying Kubernetes components...
* Enabled addons: default-storageclass, storage-provisioner
* Done! kubectl is now configured to use "minikube"
