## 验证docker ##

本地docker环境安装成功后，我们会通过运行 hello-world 映像来验证是否正确安装了 Docker Engine-Community 。

sudo docker run hello-world

## 报错信息 ##

[root@localhost ~]# sudo docker run hello-world
    Unable to find image 'hello-world:latest' locally
    docker: Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled (Client.Timeout exceeded while awaiting headers).
    See 'docker run --help'.

## 解决办法 ##

docker默认的源为国外官方源，下载速度较慢，可改为国内源

编辑或新建配置文件 /etc/docker/daemon.json  
daemon.json

{
        "registry-mirrors": ["https://registry.docker-cn.com","http://hub-mirror.c.163.com"],
        "live-restore": true
    }

重新启动docker服务

systemctl restart docker
