Docker_Desktop启动Kubernetes
参考仓库：https://github.com/AliyunContainerService/k8s-for-docker-desktop
视频参考：《如何安装Docker Desktop for Win10 》
 
安装的Docker_Desktop的版本是2.1.0.40693
<img src="https://img2020.cnblogs.com/blog/299612/202004/299612-20200408111935646-394816357.png">
安装完成后，查看版本资料（又变成了2.1.0.5），可以看到Kubernetes版本是v1.14.8 
<img src="https://img2020.cnblogs.com/blog/299612/202004/299612-20200408112005955-1460518687.png">
 
 
设置分享磁盘

为Docker分配4核CPU，8G内存
<img src="https://img2020.cnblogs.com/blog/299612/202004/299612-20200408112051925-1421847434.png">
 
 
为应用增加阿里云镜像加速器
<img src="https://img2020.cnblogs.com/blog/299612/202004/299612-20200408112118624-454790488.png">
 
 
Kubernetes先不着急启用
<img src="https://img2020.cnblogs.com/blog/299612/202004/299612-20200408112214641-1670735329.png">
 
 
查看https://github.com/AliyunContainerService/k8s-for-docker-desktop 中的介绍，如刚才所看，docker_desktop v2.1.0的kubenetes版本是v1.14.8 
<img src="https://img2020.cnblogs.com/blog/299612/202004/299612-20200408112253106-1778840185.png">
 
 
 我们将仓库切换到v1.14.8的分支
<img src="https://img2020.cnblogs.com/blog/299612/202004/299612-20200408112323589-241529781.png">
 
 
切换了分支后，然后在仓库中运行Powershell命令，执行./load_images.ps1
<img src="https://img2020.cnblogs.com/blog/299612/202004/299612-20200408112351340-93039322.png">
 
 
运行脚本，下载镜像
<img src="https://img2020.cnblogs.com/blog/299612/202004/299612-20200408112417643-810495492.png">
 
 
经过不到一分钟的等待，镜像就全部下载完成了
<img src="https://img2020.cnblogs.com/blog/299612/202004/299612-20200408112441893-1225396972.png">
 
 
回到docker desktop中，启动kubenetes，并选择show system containers，点击apply按钮
<img src="https://img2020.cnblogs.com/blog/299612/202004/299612-20200408112503066-1093616538.png">
 
 
确定安装
<img src="https://img2020.cnblogs.com/blog/299612/202004/299612-20200408112514207-1684319826.png">
 
 
等待安装kubenetes
<img src="https://img2020.cnblogs.com/blog/299612/202004/299612-20200408112541487-390946230.png">
 
 
关于启动时候的日志，存放的位置在C:\ProgramData\DockerDesktop\service.txt
<img src="https://img2020.cnblogs.com/blog/299612/202004/299612-20200408112608826-1232041429.png">
 
 
经过大概两分钟的等待，Kubernetes启动成功
<img src="https://img2020.cnblogs.com/blog/299612/202004/299612-20200408112635549-3244029.png">
 
 
powershell查看kubectl 版本
<img src="https://img2020.cnblogs.com/blog/299612/202004/299612-20200408112658818-1282803287.png">
