# docker阿里云镜像加速
# 步骤
1.登录 阿里云网站
2.注册阿里云账户
3.获取加速器地址连接
4.配置本地docker进行镜像加速器
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
[root@laptop ~]$ docker -v
Docker version 19.03.4, build 9013bf583a
[root@laptop ~]$ mkdir -p /etc/docker
[root@laptop ~]$ tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://1664le6h.mirror.aliyuncs.com"]
}
EOF
5.重启docker后台程序
[root@laptop ~]$ systemctl daemon-reload
[root@laptop ~]$ systemctl restart docker
6.测试
[root@laptop ~]# docker info

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
