我正在尝试让Kafka第一次在docker- compose上工作。该应用程序在没有docker的情况下运行良好。但是在docker上,出现如下所述的错误。卡夫卡为何会抛出此错误?
错误:
email-service_1 | 2018-12-01 14:32:02.448警告1 — [ntainer#0-0-C-1] oakcNetworkClient:[Consumer clientId = consumer-2,groupId = kafka] 1个分区的领导者经纪人没有匹配的侦听器,包括[email-token-0]
我的docker-compose配置:
version: '3.3' services: zookeeper: image: wurstmeister/zookeeper ports: - "2181:2181" kafka: image: wurstmeister/kafka command: [start-kafka.sh] environment: KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181 KAFKA_ADVERTISED_HOST_NAME: 192.168.23.134 KAFKA_CREATE_TOPICS: "email-token:1:1" volumes: - /var/run/docker.sock:/var/run/docker.sock ports: - "9092:9092" depends_on: - zookeeper email-service: build: ./email-service environment: SPRING_KAFKA_BOOTSTRAPSERVERS: kafka:9092 ports: - "8081:8081" depends_on: - kafka
如对您的问题的评论所述,问题似乎出在Kafka经纪人的广告名称上。根据您的docker- compose,您应该使用,192.168.23.134但您的电子邮件服务正在使用kafka:9092。您可以尝试使用此docker- compose。我用提供的最新Zookeeper和Kafka替换了wurstmeister服务,confluentinc并添加了您的电子邮件服务。
192.168.23.134
kafka:9092
confluentinc

advertised.listeners :发布到ZooKeeper以便客户端使用的监听器,如果与listeners config属性不同。在IaaS环境中,这可能需要与代理绑定的接口不同。如果未设置,将使用侦听器的值。与侦听器不同,宣告0.0.0.0元地址无效。
请注意,它KAFKA_ADVERTISED_HOST_NAME已被弃用,建议改为使用KAFKA_ADVERTISED_LISTENERS。有关更多信息,KAFKA_ADVERTISED_LISTENERS请在此处检查。
