Created June 22, 2020 08:52 — forked from AhianZhang/Docker
Windows Docker ToolBox使用阿里云加速
对于已创建的Docker Machine实例，更换镜像源的方法如下
在windows命令行执行docker-machine ssh [machine-name]进入VM bash
sudo vi /var/lib/boot2docker/profile
在--label provider=virtualbox的下一行添加--registry-mirror https://xxxxxxxx.mirror.aliyuncs.com
重启docker服务：
sudo /etc/init.d/docker restart
或者重启VM：exit退出VM bash，在windows命令行中执行docker-machine restart
## 如果是新建Docker Machine实例，参考阿里云的操作文档https://cr.console.aliyun.com/#/accelerator
