kafka配置解释：

    environment:
      ### 通用配置
      # 允许使用kraft，即Kafka替代Zookeeper
      - KAFKA_ENABLE_KRAFT=yes
      # kafka角色，做broker，也要做controller
      - KAFKA_CFG_PROCESS_ROLES=broker,controller
      # 指定供外部使用的控制类请求信息
      - KAFKA_CFG_CONTROLLER_LISTENER_NAMES=CONTROLLER
      # 定义kafka服务端socket监听端口
      - KAFKA_CFG_LISTENERS=PLAINTEXT://:,CONTROLLER://:9093
      # 定义安全协议
      - KAFKA_CFG_LISTENER_SECURITY_PROTOCOL_MAP=CONTROLLER:PLAINTEXT,PLAINTEXT:PLAINTEXT
      # 使用Kafka时的集群id，集群内的Kafka都要用这个id做初始化，生成一个UUID即可
      - KAFKA_KRAFT_CLUSTER_ID=LelMdIFQkiUFvXCEcqRWA
      # 集群地址
      - KAFKA_CFG_CONTROLLER_QUORUM_VOTERS=@kafka11:9093,2@kafka22:9093,3@kafka33:9093

      # 不允许自动创建主题
      - KAFKA_CFG_AUTO_CREATE_TOPICS_ENABLE=false

      ### broker配置
      # 定义外网访问地址（宿主机ip地址和端口）
      - KAFKA_CFG_ADVERTISED_LISTENERS=PLAINTEXT://.168.1.54:9292
      # broker.id，必须唯一
      - KAFKA_BROKER_ID=

4、启动服务

docker compose up -d

5、测试kafka

#进入机器kafka容器内部，创建并查看是否存在刚创建的topic，如果存在则说明Kafka集群搭建成功。
docker exec -it k1 bash
#创建topic
kafka-topics.sh --create --bootstrap-server 10.10.111.33:9092 --replication-factor 1 --partitions 3 --topic ODSDataSync
#查看topic
kafka-topics.sh --bootstrap-server 10.10.111.33:9092 --describe --topic ODSDataSync
docker exec -it k2 bash
