ConFluent模式注册表无法连接到Kafka容器

Question

我试图运行Kafka服务与Zookeper，Kafdrop和模式注册表，我使它的工作安装Kafka，Zookeper和Kadrop在一个容器，然后安装合流模式注册表在另一个（与自己的Kafka，Zoowatch，Ksql服务器和Rest代理），然而尝试要使kafdrop读取模式注册表不工作，所以现在我想只安装一个容器与Kafka，Zoowatch，Kafdrop和模式注册表，即使一切都成功安装，模式注册表是重新启动每10秒左右，我不能联系服务（localhost:8085）来添加我的模式，所以我想知道是否有可能在融合服务套件之外运行融合模式注册表，这是我的YAML文件：

version: '2'
services:
  kafka:
    image: wurstmeister/kafka
    container_name: kafka
    ports:
      - "9092:9092"
    environment:
      - KAFKA_ADVERTISED_HOST_NAME=127.0.0.1
      - KAFKA_ADVERTISED_PORT=9092
      - KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181
      - KAFKA_LISTENERS=INTERNAL://:29092,EXTERNAL://:9092
      - KAFKA_ADVERTISED_LISTENERS=INTERNAL://kafka:29092,EXTERNAL://localhost:9092
      - KAFKA_LISTENER_SECURITY_PROTOCOL_MAP=INTERNAL:PLAINTEXT,EXTERNAL:PLAINTEXT
      - KAFKA_INTER_BROKER_LISTENER_NAME=INTERNAL
      - KAFKA_SCHEMA_REGISTRY_URL=schemaregistry:8085
    depends_on:
      - zookeeper

  zookeeper:
    image: wurstmeister/zookeeper
    container_name: zookeeper
    ports:
      - "2181:2181"
    environment:
      - KAFKA_ADVERTISED_HOST_NAME=zookeeper
   
  schemaregistry:
    image: confluentinc/cp-schema-registry:6.2.0
    restart: always
    depends_on:
      - zookeeper
    environment:
      SCHEMA_REGISTRY_KAFKASTORE_CONNECTION_URL: "zookeeper:2181"
      SCHEMA_REGISTRY_HOST_NAME: schemaregistry
      SCHEMA_REGISTRY_LISTENERS: "http://0.0.0.0:8085"
    ports:
      - 8085:8085

  kafdrop:
    image: obsidiandynamics/kafdrop
    container_name: kafdrop
    restart: "no"
    ports:
      - "9000:9000"
    environment:
      KAFKA_BROKERCONNECT: "kafka:29092"
      JVM_OPTS: "-Xms16M -Xmx48M -Xss180K -XX:-TieredCompilation -XX:+UseStringDeduplication -noverify"
      SCHEMAREGISTRY_CONNECT: schemaregistry:8085
    depends_on:
      - "kafka"

Answer 1

你的两个YAML是不正确的你有在动物园管理员：KAFKA_ADVERTISED_HOST_NAME

在模式注册表中，您在kafkastore中提供zookeeper端口2181。。。。

Answer 2

因此，事实证明，架构注册表无法连接，因为Kafka没有使用PLAINTEXT作为内部代理侦听器名称，以下是与Kafdrop一起工作的YAML版本，在反序列化消息到AVRO时也在工作：

version: '2'
services:
  kafka:
    image: wurstmeister/kafka
    container_name: kafka
    ports:
      - "9092:9092"
    environment:
      - KAFKA_ADVERTISED_HOST_NAME=127.0.0.1
      - KAFKA_ADVERTISED_PORT=9092
      - KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181
      - KAFKA_LISTENERS=PLAINTEXT://:29092,EXTERNAL://:9092
      - KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://kafka:29092,EXTERNAL://localhost:9092
      - KAFKA_LISTENER_SECURITY_PROTOCOL_MAP=PLAINTEXT:PLAINTEXT,EXTERNAL:PLAINTEXT
      - KAFKA_INTER_BROKER_LISTENER_NAME=PLAINTEXT
      - KAFKA_SCHEMA_REGISTRY_URL=schemaregistry:8085

    depends_on:
      - zookeeper

  zookeeper:
    image: wurstmeister/zookeeper
    container_name: zookeeper
    ports:
      - "2181:2181"
    environment:
      - KAFKA_ADVERTISED_HOST_NAME=zookeeper
   
  schemaregistry:
    image: confluentinc/cp-schema-registry:6.2.0
    restart: always
    depends_on:
      - zookeeper
    environment:
      SCHEMA_REGISTRY_KAFKASTORE_CONNECTION_URL: "zookeeper:2181"
      SCHEMA_REGISTRY_HOST_NAME: schemaregistry
      SCHEMA_REGISTRY_LISTENERS: "http://0.0.0.0:8085"
    ports:
      - 8085:8085

  kafdrop:
    image: obsidiandynamics/kafdrop
    container_name: kafdrop
    restart: "no"
    ports:
      - "9000:9000"
    environment:
      KAFKA_BROKERCONNECT: "kafka:29092"
      JVM_OPTS: "-Xms16M -Xmx48M -Xss180K -XX:-TieredCompilation -XX:+UseStringDeduplication -noverify"
      SCHEMAREGISTRY_CONNECT: http://schemaregistry:8085
    depends_on:
      - "kafka"
