Docker:设置代理proxy

相信刚开始用docker的一定会遇到下面这种情况:

docker@boot2docker:~$ sudo docker search ubuntu 
FATA[0000] Error response from daemon: Get https://index.docker.io/v1/search?q=ubuntu: 
dial tcp: lookup index.docker.io: no such host

国内也基本找不到此问题的答案,基本都是归于GFW的原因,下面有个很有意思的ticket: 
https://github.com/docker/docker/issues/3203

摘抄里面一段国外友人(timthelion)发言:

I’m watching this conversation and feeling really sorry for everyone. 
I feel sorry for the Chinese people here who are just trying to use a 
cool product and I feel sorry for the Docker folks who probably feel 
kind of weird having to jump through loops for this foreign bureaucracy.

各位自行翻查字典理解最后一句话,我无意附和或吐槽~~

从里面提供的线索,你不仅无法ping通index.docker.io或cdn-registry-1.docker.io,连国内的镜像网站也是报同样的错误。尝试过很多的办法:

  1. 在docker环境内设置HTTP_PROXY和HTTPS_PROXY
  2. 修改内部/etc/hosts
  3. 修改docker.list追加国内镜像服务器地址

不过都是不管用的,办法是关掉Dcoker deamon,在启动的时候追加proxy设置。

sudo HTTP_PROXY=http://your.proxy.host:port docker -d

用Termpro再次登入192.168.59.103后,可以正常去查找image了。

docker@boot2docker:~$ sudo docker search ubuntu14 
NAME DESCRIPTION STARS OFFICIAL AUTOMATED 
ansible/ubuntu14.04-ansible Ubuntu 14.04 LTS 
with ansible 44 [OK] sktelecom/ubuntu14.10-hdw 2 [OK]
