java - Apache Kafka 主题元数据获取包含错误 : {LEADER_NOT_AVAILABLE}

Question

我正在尝试制作包含 wurstmeister/zookeeper 和 wurstmeister/kafka 的 dockerfile。如果我在计算机上运行消费者和生产者，一切正常(我在终端上运行zookeeper和kafka)。但是当我使用这个zookeper和kafka时，我的意思是当我运行这个dockerfile时，我得到了这个错误

o.a.k.c.consumer.internals.Fetcher - [Consumer clientId=consumer-1, groupId=consumerGroup1] Topic metadata fetch included errors: {log-monitoring=LEADER_NOT_AVAILABLE}

我认为是网络问题，他们在docker上找不到对方。 这是我的 docker-compose.yml

zookeeper:
  image: wurstmeister/zookeeper
  container_name: "zk"
  ports:
    - "2181:2181"
kafka:
  image: wurstmeister/kafka
  container_name: "kafka"
  ports:
    - "9092:9092"
  environment:
    KAFKA_ADVERTISED_HOST_NAME: 192.168.99.100
    KAFKA_ZOOKEEPER_CONNECT: zk:2181
    KAFKA_CREATE_TOPICS: "log-monitoring"

    - zookeeper:zk
  volumes:

mongo:
  image: mongo
  container_name: "mongo"
  ports:
    - "27017:27017"

producer:
  image: berat703/kafka-producer:0.0.3
  container_name: "producer"
  environment:

consumer:

  container_name: "consumer"
  ports:

  environment:
    - KAFKA_BROKER=kafka:9092
    - MONGODB_HOST=mongo
    - MONGODB_PORT=27017

尝试将KAFKA_ADVERTISED_HOST_NAME更改为kafka的FQDN，即。卡夫卡。无论你放在那里什么，都需要由生产者来解决。该字段也已弃用，建议使用类似 KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://kafka:9092 的内容。
