docker搭建kafka集羣

參考：https://www.jianshu.com/p/8ccd712e2599

搭建過程

1. 下載zookeeper鏡像

docker pull wurstmeister/zookeeper

2. 下載kafka鏡像

docker pull wurstmeister/kafka

3. 建立一個docker-compose.yml文件

version: '2'
services:
  zookeeper:
    image: wurstmeister/zookeeper
    ports:
      - "2181:2181"
  kafka:
    image: wurstmeister/kafka
    ports:
      - "9092"
    environment:
      KAFKA_ADVERTISED_HOST_NAME: "192.168.99.100"
      KAFKA_ZOOKEEPER_CONNECT: 192.168.99.100:2181
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

4. 啓動docker-compose

docker-compose up -d

 5. 運行kafka集羣模式

docker-compose scale kafka=3

6. 查看container

docker ps
docker ps -a

 7. 進入指定容器

docker exec -it dockertoolbox_kafka_1 /bin/bash

8. 建立Topic

$KAFKA_HOME/bin/kafka-topics.sh --create --topic test \

--zookeeper dockertoolbox_zookeeper_1:2181 --replication-factor 1 --partitions 1

9. 查看建立的topic

$KAFKA_HOME/bin/kafka-topics.sh --zookeeper

dockertoolbox_zookeeper_1:2181 \ --describe --topic test

10. 發佈消息

$KAFKA_HOME/bin/kafka-console-producer.sh --topic=test \

--broker-list dockertoolbox_kafka_1:9092

11. 接受消息

$KAFKA_HOME/bin/kafka-console-consumer.sh--bootstrap-server dockertoolbox_kafka_1:9092--from-beginning --topic test
