docker swarm 集群部署Kafka3.5，彻底告别zookeeper

介绍

1. 本次部署kafka3.5版本，彻底告别zookeeper时代，部署更加轻量，运维更加简单
2. 同时使用比较好用的kafka控制台redpandadata

docker swam 集群搭建

• 详见我的另一篇博客 Docker Swarm集群搭建，不再这里赘述。

docker-compose 文件准备

• docker-compose-kafka3-cluster.yml

networks:

    external: true

NOTE: 这个docker-compose文件里面加了资源的限制，生产环境建议取消限制

创建专属网络

docker network create --driver overlay kafka

拉取镜像

docker pull docker.io/bitnami/kafka:3.5
docker pull docker.io/redpandadata/console:latest

给docker node打标签

docker node update --label-add kafka.replica=1 node1
docker node update --label-add kafka.replica=2 node2
docker node update --label-add kafka.replica=3 node3

部署服务

• 部署服务使用 docker stack deploy，其中 -c 参数指定 compose 文件名。

docker stack deploy -c docker-compose-kafka3-cluster.yml

验证服务

• 浏览器访问：集群任意节点IP（或者域名）:9099，显示如下所示：

则表示集群创建成功。
