#安装docker
>###更新yum包
	yum update
   
>###卸载旧版本 Docker
	yum remove docker docker-common docker-selinux docker-engine
   
>###安装软件包
	yum install -y yum-utils device-mapper-persistent-data lvm2
   
>###添加 Docker yum源
	yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
	Loaded plugins: fastestmirror
	adding repo from: https://download.docker.com/linux/centos/docker-ce.repo
	grabbing file https://download.docker.com/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
	repo saved to /etc/yum.repos.d/docker-ce.repo
   
>###安装 Docker （直接yum按照docker-ce即可）   
	yum -y install docker-ce

##安装minikube

####rpm安装

![](/media//202306/2023-06-04134733177531.png)

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-latest.x86_64.rpm
	sudo rpm -Uvh minikube-latest.x86_64.rpm
	
---
####二进制包安装

![](/media//202306/2023-06-04134831810353.png)

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
	sudo install minikube-linux-amd64 /usr/local/bin/minikube

---
####创建新用户添加到docker用户组，使用此用户运行minikube：
	useradd minikube
	
	passwd minikube
	
	usermod -aG docker minikube
	
	vim /etc/sudoers 
	#添加
	minikube ALL=(ALL) NOPASSWD:ALL

####先用root用户关闭docker，然后用test用户启动docker即可
	systemstl stop docker
	
	su - minikube
	
	systemctl start docker
---
##启动
	minikube start --memory=4096mb	--image-mirror-country='cn' --image-repository='registry.cn-hangzhou.aliyuncs.com/google_containers'
	#启动时指定--image-mirror-country='cn' ，可以使用阿里云的镜像站点，来提高资源下载速度。
	#--memory=为集群内存限制，默认为2G
	
	创建第二个运行旧 Kubernetes 版本的集群：
	minikube start -p aged --kubernetes-version=v1.16.1

##管理集群
####如果已经安装了kubectl，可以直接用kubectl命令管理集群。如

kubectl get pod -A
####如果没安装，可以在kubectl前边加上minikube命令。

minikube kubectl --get pod -A

####如果本地未安装kubectl，可以通过别名方式，后续可直接使用kubectl了。
	#临时设定
	alias kubectl="minikube kubectl --" 
	
	#永久设定

####在不影响已部署应用程序的情况下暂停 Kubernetes：

minikube pause

####取消暂停暂停的实例：

minikube unpause

####停止集群：

minikube stop

---
##删除集群
####删除本地集群

minikube delte

####删除集群和配置文件

minikube delte --all

---
