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
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
