zookeeper 和 Kafka 都沟通良好并且正常运行。

不知道为什么模式注册表和卡夫卡休息不能起来。

下面是 docker-compose 文件。

这是架构和休息 docker-compose 文件。此泊坞窗上的错误

它无法启动，因为它不知道您要连接的两个侦听器中的哪一个。这不能通过提供 ZK 地址 AFAIK 来确定。无论如何，除了 Kafka 之外，你不应该需要 Zookeeper。

例如，您可以将现有的一体式撰写文件用于 Confluent

特别要注意 REST 代理没有 ZK

我在 kafka docker 环境中进行了适当的配置。

环境：

KAFKA_ZOOKEEPER_CONNECT：'动物园管理员：2181'

KAFKA_AUTO_CREATE_TOPICS_ENABLE：'真'

ALLOW_PLAINTEXT_LISTENER：“是”

KAFKA_LISTENERS: PLAINTEXT://:9092

KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka:9092

此外，kafdrop 配置不需要使用 29092。只需使用默认的 kafka 端口 9092。

KAFKA_BROKERCONNECT: "kafka:9092"
