FAQ

❌ Exiting due to DRV_DOCKER_NOT_RUNNING: Found docker, but the docker service isn’t running. Try restarting the docker service.

systemctl start docker

❌ Exiting due to DRV_AS_ROOT: The “docker” driver should not be used with root privileges.

这里当前用户使用的是 root。

解决办法：

minikube start --force --driver=docker

RPM 卸载 minikube

rpm -e minikube

YUM 卸载 Docker

yum remove docker docker-common docker-selinux docker-engine
