Docker Proxy

1. 准备环境：

- Git Bash

Pulling repository docker.io/library/registry

Network timed out while trying to connect to https://index.docker.io/v1/repositories/library/registry/images. You may want to check your internet connection or if you are behind a proxy.

3. 解决办法：

- docker-machine ssh virtual_box

- 找到 /var/lib/boot2docker/profile

- 修改Export

        * export HTTP_PROXY=http://proxy:port

        * export HTTPS_PROXY=http://proxy:port

- 重启环境 docker-machine restart virtual_box
