前提：已安装centos7.5安装VirtualBox

Minikube是什么？
Minikube是一种方便在本地运行Kubernetes的工具. 
Minikube 是可以在VM中运行单节点的Kubernetes集群. 
Minikube是为了开发或测试在本地启动一个节点的kubernetes集群.

特点
不能启动生产集群，没有高可用性的单节点机器. 
可以工作在Windows,Linux,MacOS下

3.配置变量

[email protected] network-scripts]# export MINIKUBE_WANTUPDATENOTIFICATION=false
[[email protected] network-scripts]# export MINIKUBE_WANTREPORTERRORPROMPT=false
[[email protected] network-scripts]# export MINIKUBE_HOME=$HOME
[[email protected] network-scripts]# export CHANGE_MINIKUBE_NONE_USER=true
[[email protected] network-scripts]# mkdir $HOME/.kube || true
mkdir: cannot create directory ‘/root/.kube’: File exists
[[email protected] network-scripts]# touch $HOME/.kube/config
[[email protected] network-scripts]# export KUBECONFIG=$HOME/.kube/config
[[email protected] network-scripts]# echo $MINIKUBE_WANTUPDATENOTIFICATION
false
[[email protected] network-scripts]# echo $MINIKUBE_WANTREPORTERRORPROMPT
false[[email protected] network-scripts]# echo $MINIKUBE_HOME
/root
[[email protected] network-scripts]# echo $CHANGE_MINIKUBE_NONE_USER
true
[[email protected] network-scripts]# ls $HOME/.kube/
config
[[email protected] network-scripts]# echo $KUBECONFIG
/root/.kube/config

4.启动minikube

[[email protected] network-scripts]# minikube start --vm-driver=virtualbox
o   minikube v0.35.0 on linux (amd64)
