无法使用 apt-get update 更新 ubuntu Docker 容器

当我将 ubuntu 作为 Docker 容器运行时，当我运行apt-get update命令时，它出现错误并且无法更新存储库。

以下是我遇到的错误：

问题出在互联网连接上，因为我的连接是企业级的，因此无法执行apt-get update命令。对我有用的解决方案是：

  1. 使用以下方式查找您的 DNS 服务器地址cat /etc/resolv.conf

  2. 打开 Docker confg 文件并取消注释DOCKER_OPTS，然后在那里添加你的 DNS 服务器

Docker 配置文件：sudo gedit /etc/default/docker
