此篇博文主要是记录如何在本地环境使用CentOS系统安装minikube,对于安装过程中大量出现镜像下载失败的问题做了填坑，主要是使用kubernete 1.12.1版本，对于其他不同版本，方法是一样的。
wget https://storage.googleapis.com/minikube/releases/v0.30.0/minikube-linux-amd64
mv minikube-linux-amd64 /usr/bin/minikube
wget https://dl.k8s.io/v1.12.1/kubernetes-server-linux-amd64.tar.gz
tar xf kubernetes-server-linux-amd64.tar.gz && cd kubernetes/server/bin/
cp kubectl kubeadm kubelet /usr/local/bin/上传docker-ce-17.03.2.ce-1.el7.centos.x86_64.rpm 和 docker-ce-selinux-17.03.2.ce-1.el7.centos.noarch.rpm 到服务器，运行如下命令安装docker：
yum install docker-ce-selinux-17.03.2.ce-1.el7.centos.noarch.rpm -y
yum install docker-ce-17.03.2.ce-1.el7.centos.x86_64.rpm -y启动docker服务,并将docker设置为开机自启动：
systemctl start docker
systemctl enable docker创建如下脚本：
vi auto_pull_images.sh在脚本中添加如下内容：
#!/bin/bash
images=(kube-proxy-amd64:v1.12.1 kube-scheduler-amd64:v1.12.1 kube-controller-manager-amd64:v1.12.1 kube-apiserver-amd64:v1.12.1 etcd-amd64:3.2.24 pause-amd64:3.1 kubernetes-dashboard-amd64:v1.10.0 k8s-dns-sidecar-amd64:1.14.8 k8s-dns-kube-dns-amd64:1.14.8

for imageName in ${images[@]} ; do
docker pull mirrorgooglecontainers/$imageName
docker tag mirrorgooglecontainers/$imageName k8s.gcr.io/$imageName
docker rmi mirrorgooglecontainers/$imageName
done
for n in $(docker images|awk '{print $1":"$2}'|grep -v REPOSITORY); do docker tag $n `echo $n|sed 's/-amd64//g'` && docker rmi $n; done

docker tag registry.cn-hangzhou.aliyuncs.com/anoy/storage-provisioner:v1.8.1 gcr.io/k8s-minikube/storage-provisioner:v1.8.1
docker rmi registry.cn-hangzhou.aliyuncs.com/anoy/storage-provisioner:v1.8.1运行脚本：
sh auto_pull_images.sh等待脚本运行成功后，执行如下命令，确认所需镜像已经下载到本地：
[root@node-2 ~]# docker images

minikube start --vm-driver=none --registry-mirror=https://registry.docker-cn.com --kubernetes-version v1.12.1启动dashboard:
minikube dashboard为dashboard添加外部访问代理,此处的IP为本地系统IP：
kubectl proxy --port=8001 --address='10.0.0.2' --accept-hosts='^.*' &通过url: http://10.0.0.2:8001/api/v1/namespaces/kube-system/services/http:kubernetes-dashboard:/proxy/ 访问dashboard。
