1、拉取zookeeper镜像
kafka需要zookeeper管理，所以需要先安装zookeeper。
docker pull zookeeper:3.6
2、启动zookeeper容器
docker run -d --name zookeeper -p 2181:2181 -v /etc/localtime:/etc/localtime zookeeper:3.6
3、拉取kafka镜像
docker pull wurstmeister/kafka:2.12-2.5.0
[root@~]$docker pull wurstmeister/kafka:2.12-2.5.0
Trying to pull repository docker.io/wurstmeister/kafka ...
2.12-2.5.0: Pulling from docker.io/wurstmeister/kafka

Status: Downloaded newer image for docker.io/wurstmeister/kafka:2.12-2.5.0
4、启动kafka镜像
启动kafka镜像生成容器
## docker run -d --name kafka -p 9002:9002 -e KAFKA_BROKER_ID=0 -e KAFKA_ZOOKEEPER_CONNECT=192.168.124.28:2181/kafka -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.124.28:9002 -e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9002 -v /etc/localtime:/etc/localtime wurstmeister/kafka:2.12-2.5.0
$ docker run -d --restart=always --log-driver json-file --log-opt max-size=100m --log-opt max-file=2 --name kafka -p 9002:9002 -e KAFKA_BROKER_ID=0 -e KAFKA_ZOOKEEPER_CONNECT=172.16.152.136:2181/kafka -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://172.16.152.136:9002 -e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9002 -v /etc/localtime:/etc/localtime wurstmeister/kafka:2.12-2.5.0
参数说明：
-e KAFKA_BROKER_ID=0 在kafka集群中，每个kafka都有一个BROKER_ID来区分自己
-e KAFKA_ZOOKEEPER_CONNECT=192.168.124.28:2181/kafka 配置zookeeper管理kafka的路径192.168.124.28:2181/kafka
-e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.124.28:9002 把kafka的地址端口注册给zookeeper，如果是远程访问要改成外网IP,类如Java程序访问出现无法连接。
-e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9002 配置kafka的监听端口
-v /etc/localtime:/etc/localtime 容器时间同步虚拟机的时间

5、zookeeper和kafka容器启动后的状态
[root@blog]$docker run -d --restart=always --log-driver json-file --log-opt max-size=100m --log-opt max-file=2 --name kafka -p 9002:9002 -e KAFKA_BROKER_ID=0 -e KAFKA_ZOOKEEPER_CONNECT=192.168.124.28:2181/kafka -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.124.28:9002 -e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9002 -v /etc/localtime:/etc/localtime wurstmeister/kafka:2.12-2.5.0

6、验证kafka是否可用
6.1、进入镜像内
查看zookeeper中有关kafka的配置
docker exec -it 53f73b512f02 /bin/bash
sh zkCli.sh -server 127.0.0.1:2181
[zk: 127.0.0.1:2181(CONNECTED) 7] ls /
[zookeeper, kafka]
[zk: 127.0.0.1:2181(CONNECTED) 8] ls /kafka
[cluster, controller, controller_epoch, brokers, admin, isr_change_notification, consumers, config]
[zk: 127.0.0.1:2181(CONNECTED) 9]
进入kafka容器查看
[root@blog]$docker exec -it d8e3973e228c /bin/sh
/ # ps -ef
