在mac osx上新的docker.我正在从基本的phusion图像构建一个ubuntu图像,以用作git服务器.使用以下文件安装基础和所需的软件.这非常有效.但是,我无法ping通机器.

编辑

我无法ping通机器.我可以运行图像并在ps命令中查看容器.我也可以抨击它.

CONTAINER ID        IMAGE               COMMAND               CREATED             STATUS              PORTS               NAMES

以下也有效

docker exec -it 54e4cef78445 ping www.google.com
