failed to pull image

虚拟机内使用minikube start --vm-driver=none装minikube时,报的这个

[preflight] You can also perform this action in beforehand using 'kubeadm config images pull'
error execution phase preflight: [preflight] Some fatal errors occurred:
        [ERROR ImagePull]: failed to pull image output: Trying to pull repository ...
Get dial tcp connect: connection refused
, error: exit status 1

可以执行minikube start --vm-driver=none --image-mirror-country=cn; 来指定国内镜像源。
