Dockerizing kafka给出非零退出代码
我是一个试图学习docker的新手。 我正在试图dockerize kafka安装，并坚持一个非零退出代码。 我想debugging问题并找出原因。 如何debuggingdocker文件。
我试图通过使用dockerd -D在debugging模式下执行dockerd。但是这并没有给出任何详细的日志logging。
我正在一个stream浪者开发箱内运行我的脚本。 有没有什么办法可以在debugging模式下执行构build。
以下是我的docker文件。

总是使用apt-get install -y所以没有用户提示。
CMD也需要在前台运行，不需要使用日志文件。 Docker有一个stdout / stderr日志接口，可以通过docker logs CONTAINER访问。

我在github上有一个基于Debian的kafka图像 ，包括一些更详细的设置。
