修改docker-仓库资源地址Error response from daemon: Get https://index.docker.io/v1/search

[root@zengmg /]# docker search centos
Error response from daemon: Get https://index.docker.io/v1/search?q=centos: read tcp 52.200.132.201:443: i/o timeout

docker在中国已经有了仓库：https://www.docker-cn.com/registry-mirror

根据上面网站提供的修改方法。

进入/etc/docker

查看有没有 daemon.json。这是docker默认的配置文件。

如果没有新建，如果有，则修改。

[root@zengmg docker]# vi daemon.json
{
"registry-mirrors": ["https://registry.docker-cn.com"]
}

保存退出。

重启docker服务

service docker restart

成功！
