Python - 装机系列63 docker镜像不通 no such host
作者：互联网
说明
主要的问题大概是我的两台电脑连到了一个交换机，交换机再连到路由器，导致dns出问题
内容
故障现象
Error response from daemon: Get https://registry.cn-hangzhou.aliyuncs.com/v2/: dial tcp: lookup registry.cn-hangzhou.aliyuncs.com: no such host
解决方法：
vim /etc/resolv.conf
#nameserver 127.0.0.53
nameserver 223.5.5.5
options edns0
把默认的dns设置改为阿里云的dns，保存即生效
