Windows docker-compose Kafka集群【排坑】

Windows docker-compose Kafka集群【排坑】

Windows中，使用VMWare进行配置没有过多问题，但是当使用Windows下的docker时，Kafka的监听配置就是个大坑。 核心问题在于：​​ADVERTISED_LISTENERS​​​ 和​​LISTENERS​​ 的理解​​host.docker.internal​​ 的理解​​Kafka​​​ 的 ​​ADVERTISED_LISTENERS​​ 配置是保存的字符串，客户端请求的时候会返回这个配置信息。

docker-compose.yml
