docker下部署kafka集群(多个broker+多个zookeeper)

网上关于kafka集群的搭建，基本是单个broker和单个zookeeper，测试研究的意义不大。于是折腾了下，终于把正宗的Kafka集群搭建出来了，在折腾中遇到了很多坑，后续有时间再专门整理份搭建问题分析

docker-compose.yml配置文件

version: '2'
services:
    zoo1:
        image: zookeeper
        restart: always
        container_name: zoo1
        ports:
            - "2181:2181"
        environment:

    zoo2:
        image: zookeeper
        restart: always
        container_name: zoo2
