今天刚刚使用他们的安装指南安装了 docker 1.10.1。--net=host但是，除非我在docker run命令中使用，否则我的容器都不能访问互联网。我从这些帖子中尝试了各种解决方法：
- http://odino.org/cannot-connect-to-the-internet-from-your-docker-containers/
- 我的 docker 容器没有互联网
- 我无法让 Docker 容器访问互联网？
- Docker 容器无法访问互联网
到目前为止，除了添加--net=host到运行命令外，没有任何效果，但我无法从 Dockerfile 构建图像，因为我不能--net=host与该build命令一起使用。
我跑去docker network inspect bridge检查 docker 网桥的设置，发现它使用（几乎）与我的工作 VPN 相同的子网和网关。这会导致问题吗？这也可以解释为什么当我连接到我的工作 VPN 时，有些网站没有加载。
这是结果docker network inspect bridge：
