1. 机器准备

   准备三台机器，IP分别为192.168.10.51、192.168.10.52、192.168.10.53;主机名分别为centos51、centos52、centos53。三台机器已经准备好docker swarm环境。docker swarm搭建可以参考另一篇文章 docker swarm 集群搭建。

2. 准备镜像。

    在 https://hub.docker.com/ 上拉取zookeeper、kafka、kafka manager相关镜像

docker pull zookeeper:3.6.1
docker pull wurstmeister/kafka:2.12-2.5.0
docker pull kafkamanager/kafka-manager:3.0.0.4

3. zookeeper 相关compose准备。

    deploy:
      replicas: 1
      restart_policy:
        condition: on-failure
      placement:
        constraints: [node.hostname == centos52]
      resources:
        limits:
#          cpus: '1'
          memory: 1GB

5. kafka manager相关compose准备

文件名： docker-stack-kafka-manager.yml

version: "3.2"
services:
#kafka manager服务
  kafka-manager:

    deploy:
      replicas: 1
      restart_policy:
        condition: on-failure
      placement:
        constraints: [node.hostname == centos51]
      resources:
        limits:
#          cpus: '1'
          memory: 1GB
        reservations:
#          cpus: '0.2'
          memory: 512M

networks:
  avatar-net:
    external:
      name: swarm-net

6. 在三台机器上创建文件映射路径

mkdir -p {/data/kafka_cluster/zookeeper/data,/data/kafka_cluster/kafka/data,/data/kafka_cluster/kafka/logs}
chown -R 777 /data/kafka_cluster/

7. 执行compose

一定要按照顺序执行，执行成功再执行下一个命令

 docker stack deploy -c docker-stack-zookeeper.yml zoo --resolve-image=never --with-registry-auth
 docker stack deploy -c docker-stack-kafka.yml kafka  --resolve-image=never --with-registry-auth
docker stack deploy -c docker-stack-kafka-manager.yml kafka_manager  --resolve-image=never --with-registry-auth
