linux通过docker安装kafka

1、安装docker

2、拉取kafka和zk的镜像

docker pull wurstmeister/kafka
docker pull zookeeper:3.5.7

3、创建通信网络

docker network create kafkanet

4、创建kafka和zk容器

　　 4.1 创建zk容器

docker run --net=kafkanet  --name yhq_zookeeper1  -p 21810:2181  -d zookeeper:3.5.7

　　4.2 查看zk的网络

docker inspect yhq_zookeeper1

　　4.3 创建kafka容器

docker run --net=kafkanet --name yhq_kafka1 -p 9093:9092 \
--link yhq_zookeeper1 \
-e KAFKA_ZOOKEEPER_CONNECT=172.20.0.2:2181 \
-e KAFKA_ADVERTISED_HOST_NAME=192.168.146.190 \
-e KAFKA_ADVERTISED_PORT=9092 \
-d wurstmeister/kafka

　KAFKA_ADVERTISED_HOST_NAME 参数需要设置为宿主机地址192.168.146.190。

　 KAFKA_ZOOKEEPER_CONNECT 参数设置hbl-zookeeper容器内部地址和端口（同一宿主机内的容器互相访问要用容器内地址，查看指令为docker inspect hbl_zookeeper，在Networks字段可以看到容器内ip地址）。

　　4.4 查看通信网络，zk和kafka容器都加入到网络中

　　

 　　5、kafka容器操作

docker exec -it 7cd bash  #kafka容器ip以7cd开头，可以通过docker ps命令查看容器

　　进入到kafka容器后，查看opt/kafka_2.12-2.4.1/config/server.properties和zookeeper.properties ,可以看到已经配置好zk等相关配置
