使用Docker快速搭建Zookeeper和kafka集群
集群搭建镜像选择
Zookeeper和Kafka集群分别运行在不同的容器中
zookeeper官方镜像，版本3.4
kafka采用wurstmeister/kafka镜像

宿主机root OSX
192.168.21.139【DHCP获取，会变动】
实现目标
kafka集群在docker网络中可用，和zookeeper处于同一网络
宿主机可以访问zookeeper集群和kafka的broker list
docker重启时集群自动重启
集群的数据文件映射到宿主机器目录中
使用yml文件和$ docker-compose up -d命令创建或重建集群
$ docker-compose up -d

结果查看和测试
宿主机命令行创建topic
$ pwd
/Users/shaozhipeng/Development/kafka_2.11-2.0.0/bin
$ ./kafka-topics.sh --create --zookeeper localhost:2184,localhost:2185,localhost:2186 --replication-factor 1 --partitions 1 --topic test1
Kafka Tool查看
docker ps查看正在运行的容器
查看宿主机IP地址，并设置Host
这样宿主机就可以访问kafka集群了
