Using the docker driver based on user configuration
The "docker" driver should not be used with root privileges.
If you are running minikube within a VM, consider using --driver=none:

Exiting due to DRV_AS_ROOT: The "docker" driver should not be used with root privileges.
Solution:
[root@zhangpeilei ~]# minikube start --force --driver=docker
