使用Docker快速搭建Zookeeper和kafka集群

集群搭建

鏡像選擇

Zookeeper和Kafka集群分別運行在不同的容器中
zookeeper官方鏡像，版本3.4
kafka采用wurstmeister/kafka鏡像

集群規劃

實現目標

kafka集群在docker網絡中可用，和zookeeper處于同一網絡
宿主機可以訪問zookeeper集群和kafka的broker list
docker重啟時集群自動重啟
集群的數據文件映射到宿主機器目錄中
使用yml文件和$ docker-compose up -d命令創建或重建集群

$ docker-compose up -d

zk集群的docker-compose.yml

version: '3.4'

services:
  zoo1:
    image: zookeeper

    hostname: zoo1

kafka集群的docker-compose.yml

kfkluster少拼了個c...

version: '2'

services:
  kafka1:
    image: wurstmeister/kafka
    restart: always
    hostname: kafka1
    container_name: kafka1
    ports:
    - 9092:9092
    environment:
      KAFKA_ADVERTISED_HOST_NAME: kafka1
      KAFKA_ADVERTISED_PORT: 9092
      KAFKA_ZOOKEEPER_CONNECT: zoo1:2181,zoo2:2181,zoo3:2181
    volumes:
    - /Users/shaozhipeng/Development/volume/kfkluster/kafka1/logs:/kafka
    external_links:
    - zoo1
    - zoo2
    - zoo3
    networks:
      br17219:
        ipv4_address: 172.19.0.14

  kafka2:
    image: wurstmeister/kafka
    restart: always
    hostname: kafka2
    container_name: kafka2
    ports:
    - 9093:9093
    environment:
      KAFKA_ADVERTISED_HOST_NAME: kafka2
      KAFKA_ADVERTISED_PORT: 9093
      KAFKA_ZOOKEEPER_CONNECT: zoo1:2181,zoo2:2181,zoo3:2181
    volumes:
    - /Users/shaozhipeng/Development/volume/kfkluster/kafka2/logs:/kafka
    external_links:
    - zoo1
    - zoo2
    - zoo3
    networks:
      br17219:
        ipv4_address: 172.19.0.15

  kafka3:
    image: wurstmeister/kafka
    restart: always
    hostname: kafka3
    container_name: kafka3
    ports:
    - 9094:9094
    environment:
      KAFKA_ADVERTISED_HOST_NAME: kafka3
      KAFKA_ADVERTISED_PORT: 9094
      KAFKA_ZOOKEEPER_CONNECT: zoo1:2181,zoo2:2181,zoo3:2181
    volumes:
    - /Users/shaozhipeng/Development/volume/kfkluster/kafka3/logs:/kafka
    external_links:
    - zoo1
    - zoo2
    - zoo3
    networks:
      br17219:
        ipv4_address: 172.19.0.16

networks:
  br17219:
    external:
      name: br17219

結果查看和測試

宿主機命令行創建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查看正在運行的容器

查看宿主機IP地址，并設置Host

這樣宿主機就可以訪問kafka集群了
