Error response from daemon: Get https://registry-1.docker.io/v2/: dial tcp: lookup registry-1.docker

1. 下载基础镜像 Centos ，docker pull centos 到本地一直报错
   Error response from daemon: Get https://registry-1.docker.io/v2/library/centos/manifests/latest: Get https://auth.docker.io/token?scope=repository%3Alibrary%2Fcentos%3Apull&service=registry.docker.io: dial tcp: lookup auth.docker.io on 127.0.0.53:53: server misbehaving
    
2. 解决方法如下：
    a：通过dig @114.114.114.114 registry-1.docker.io找到可用IP
    
    b：尝试修改/etc/hosts强制docker.io相关的域名解析到其它可用IP，上面选一个即可
