2、修改配置文件

针对Docker客户端版本大于 1.10.0 的用户

您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器

>sudo mkdir -p /etc/docker
>sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://dcjtn3xm.mirror.aliyuncs.com"]
}
EOF

3、加载重启docker

>sudo systemctl daemon-reload
>sudo systemctl restart docker

4、是否成功
