我是docker的新手，我有以下问题。
我的应用程序与kafka对话，我理解为了测试需要一个kafka容器。但是，真正的Kafka安装存在于docker之外的服务器上。我还需要Kafka和zookeeper docker集装箱吗？我可以配置我的应用程序的docker容器来指向真正的kafka和zookeeper吗？如果没有，那么如何让kafka/zookeeper容器访问真正的kafka安装？
我从docker的文档中看到，“network\u mode:bridge”是默认值，但当我显式地将其放入时，会出现无法连接到主机的错误。这就是为什么我把它注解掉了，所以如果有人能回答我为什么，我将不胜感激？
我的应用程序需要访问外部网络共享驱动器才能处理文件，并且对这些驱动器具有读/写权限。我如何给我的容器这样的访问权限？现在，当我传递一个路径，例如c:\myfolder\myfile.txt，当我尝试读取文件时，它会被附加/app/c:\myfolder\myfile.txt
这是我的docker-compose.yml文件。
