docker: Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled
今天在使用docker獲取鏡像時，出現了鏡像獲取報錯的問題，找到了解決的方法記一下。
1、問題docker
➜ ~ 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 timeouttcp➜ ~ 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)
➜ ~spa
2、處理.net
第一步：經過dig @114.114.114.114 registry-1.docker.io找到可用IPcode

第二步：嘗試修改/etc/hosts強制docker.io相關的域名解析到其它可用IPserver
