Docker配置阿里云镜像加速

访问 https://help.aliyun.com/document_detail/60750.html

点击进入控制台

前往开通

设置密码

确定，进来后，点击镜像加速器

就冒出来配置方法，很简单的，就是拿到加速地址，然后去搞个json文件即可。

vim /etc/docker/daemon.json

# 添加如下内容，具体地址自己申请咯
{
  "registry-mirrors": ["https://****.mirror.aliyuncs.com"]
}

# 重启服务
systemctl daemon-reload
systemctl restart docker

这个时候查看docker信息
