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)

;; msg size rcvd: 493第二步：尝试修改/etc/hosts强制docker.io相关的域名解析到其它可用ip
54.164.230.151 registry-1.docker.io保存之后重试:
➜ ~ docker search sameersbn
我们可看到，已经可以获取数据了。
三、使用docker国内镜像
使用 daocloud 提供的镜像
docker for mac
右键点击桌面顶栏的 docker 图标，选择 preferences ，在 daemon 标签（docker 17.03 之前版本为 advanced 标签）下的 registry mirrors 列表中加入下面的镜像地址:
http://141e5461.m.daocloud.io点击 apply & restart 按钮使设置生效。
docker toolbox 等配置方法请参考帮助文档。
