docker-compose安装带SASL认证的kafka

本篇文章会介绍使用使用`docker-compose`安装带SASL认证的Kafka消息队列。为啥会有这篇文章主要是网上一些文章太折磨人了，都是互抄的而且都是错的。我配合`SpringBoot`调试搞了我一天。为啥要搞SASL认证也主要是为了安全考虑。如果不加认证，`Kafka`应用就是裸露在外面的，会有安全风险。阅读此文前，需要对`docker-compose`有一个基础认知，本文并不属于小白文

以下三个文件为zookeeper的配置文件，除zoo.cfg（核心）文件做了改变，其余都是使用docker cp 命令从zookeeper容器copy出来的。

tickTime=2000

# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.

# the port at which the clients will connect

# the maximum number of client connections.
# increase this if you need to handle more clients
