docker daemon proxy 設定 on CentOS 6

1. 編輯 docker daemon 設定檔，設定 docker daemon 的 proxy
   

   # vim /etc/sysconfig/docker
   other_args=
   export HTTP_PROXY="http://<ip>:<port>"
   export HTTPS_PROXY="https://<ip>:<port>"

2. 重新啟動 docker daemon
   

   # service docker restart

3. 搜尋 coreos image
   

   # docker search coreos
