　　一，安装docker

#Step 2:安装必要包
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
# Step 2: 添加软件源信息
sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# Step 3: 更新并安装Docker-CE
sudo yum makecache fast
sudo yum -y install docker-ce
# Step 4: 开启Docker服务
sudo service docker start
systemctl enable docker

 　　二，安装kubectl

　　下载二进制包https://github.com/kubernetes/kubernetes/releases

　　解压 后把可执行程序kubectl移动至/usr/local/bin

　　三，安装minikube

　　下载

wget https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64

 　　安装

 mv minikube-linux-amd64 minikube
chmox +x minikube
 mv minikube /usr/local/bin/
#安装需要设置成国内源
minikube start --image-repository='registry.cn-hangzhou.aliyuncs.com/google_containers'

 　　查看

# kubectl get cs,node
NAME                                 STATUS    MESSAGE             ERROR
componentstatus/scheduler            Healthy   ok                  
componentstatus/controller-manager   Healthy   ok                  
componentstatus/etcd-0               Healthy   {"health":"true"}   

NAME                STATUS   ROLES    AGE   VERSION
node/k8s-minikube   Ready    master   17m   v1.17.3

 　　创建一个测试用例

kubectl run nginx --image=nginx --port=80
kubectl expose deployment nginx --port=80 --target-port=80 --type=NodePort

 　　查看

# kubectl get node,svc
NAME                STATUS   ROLES    AGE   VERSION
node/k8s-minikube   Ready    master   19m   v1.17.3

NAME                 TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)        AGE
service/kubernetes   ClusterIP   10.96.0.1      <none>        443/TCP        19m
service/nginx        NodePort    10.106.214.5   <none>        80:30807/TCP   15m

 　　能使用node加NodePort端口访问即可，单机minikube搭建完成，可由于开发及测试。
