docker更改镜像配置后报错

vim /etc/docker/daemon.json

{

    "registry-mirrors" : ["https://registry.docker.docker-cn.com"]

}

修改配置后报错：

Error response from daemon: Get https://index.docker.io/v1/search?q=java&n=25: dial tcp: lookup index.docker.io: no such host

解决方案：

vim /etc/resolv.conf

nameserver 8.8.8.8

nameserver 8.8.8.4

重启服务

systemctl restart network
