Docker获取镜像报错docker: Error response from daemon

今天在使用docker获取镜像时，出现了镜像获取报错的问题，找到了解决的方法记一下。

一、问题

➜ ~ docker search sameersbn
Error response from daemon: Get https://index.docker.io/v1/search?q=sameersbn&n=25: dial tcp: lookup index.docker.io on 192.168.65.1:53: read udp 192.168.65.2:45190->192.168.65.1:53: i/o timeout

➜ ~ docker pull sameersbn
Using default tag: latest
Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)
➜ ~

二、处理

第一步：通过dig @114.114.114.114 registry-1.docker.io找到可用IP

➜ ~ dig @114.114.114.114 registry-1.docker.io; <<>> DiG 9.8.3-P1 <<>> @114.114.114.114 registry-1.docker.io; (1 server found);; global options: +cmd;; Got answer:;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 47220;; flags: qr rd ra; QUERY: 1, ANSWER: 8, AUTHORITY: 4, ADDITIONAL: 9;; OPT PSEUDOSECTION:; EDNS: version: 0, flags:; udp: 4096;; QUESTION SECTION:;registry-1.docker.io.
