Kafka Kraft集群节点频繁断开，多分区生产消费异常求助

环境背景 #

计划基于Bitnami Kafka 3.3.1版本搭建3节点Kraft集群，实际使用bitnami/kafka:3.4.0-debian-11-r11镜像部署。该集群在Kubernetes环境可正常运行，但Docker Compose部署时出现多类异常。

异常现象 #

• 节点频繁断开，Docker日志输出INFO [RaftManager nodeId=2] Node 1 disconnected.，Python客户端无法正常生产或消费消息
• 执行kafka-console-producer.sh时触发NOT_LEADER_OR_FOLLOWER错误
• kafka-console-consumer.sh运行状态不稳定，时好时坏
• 单分区主题可正常工作，但多分区主题会触发上述所有异常，Python客户端消费者无法监听消息

已尝试更换镜像版本、更换Python客户端，问题仍未解决。

Broker1的Docker Compose配置 #
