我是一个试图学习码头工的新手。我试图将kafka安装停靠，并坚持使用非零退出代码。我想调试问题并找出原因。如何调试docker文件。
我尝试使用dockerd -D在调试模式下执行dockerd。但这并没有提供任何详细的日志记录。
我在一个流氓开发盒里面运行我的脚本。有什么办法可以在调试模式下执行构建。
下面是我的泊坞文件。

始终使用apt-get install -y，因此没有用户提示。
CMD也需要在前台运行，并且不需要使用日志文件。 Docker有一个stdout / stderr日志记录界面，可以通过docker logs CONTAINER访问。

我有一个基于Debian的kafka image on github，其中包含更详细的设置。
