Question

我正在尝试制作具有wurstmeister / zookeeper和wurstmeister / kafka的dockerfile。如果我在计算机上运行使用者和生产者，那么一切都可以正常运行（我在终端上运行zookeeper和kafka）。但是，当我使用此zookeper和kafka时，我的意思是当我运行此dockerfile时，出现此错误

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

我认为有关网络的问题，他们在docker上找不到彼此。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"
  links:
    - zookeeper:zk
  volumes:
    - /var/run/docker.sock:/var/run/docker.sock
mongo:
  image: mongo
  container_name: "mongo"
  ports:
    - "27017:27017"

producer:
  image: berat703/kafka-producer:0.0.3
  container_name: "producer"
  environment:
    - KAFKA_BROKER=kafka:9092
  links:
    - kafka:kafka
consumer:
  image: berat703/kafka-consumer:0.0.2
  container_name: "consumer"
  ports:
    - "8080:8080"
  environment:
    - KAFKA_BROKER=kafka:9092
    - MONGODB_HOST=mongo
    - MONGODB_PORT=27017
  links:
    - kafka:kafka

Answer 1

尝试将KAFKA_ADVERTISED_HOST_NAME更改为kafka的FQDN，即。 kafka。无论您放在哪里，生产者都可以解决。该字段也已弃用，建议改用KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://kafka:9092之类的内容。

Apache Kafka主题元数据获取包含以下错误：{LEADER_NOT_AVAILABLE}
