问题描述
制作了一个docker镜像,运行dnsmasq。域名解析竟然无应答, no servers cloud be reached
- 发送请求解析域名
dig www.google.com @192.168.0.111 -p 53 ; <<>> DiG 9.11.3-RedHat-9.11.3-4.fc27 <<>> www.google.com @192.168.0.111 -p 53 ;; global options: +cmd ;; connection timed out; no servers could be reached
- dnsmasq打印日志。从日志中发现缺少reply

解决办法。
尝试了很多方法,很奇怪它为什么不能应答。dnsmasq也不大,放在宿主机上运行吧。
