卡夫卡设置与码头构成

Question

嗨，我目前正在与码头设置卡夫卡。我已经成功地建立动物园管理员和卡夫卡与发布的融合图像，请参阅下面的码头工人，撰写文件：

version: '2' 

services: 
    zookeeper: 
    image: confluentinc/cp-zookeeper:3.2.0 
    container_name: zookeeper 
    hostname: zookeeper 
    ports: 
     - "2181:2181" 
    environment: 
     ZOOKEEPER_CLIENT_PORT: 2181 
     ZOOKEEPER_TICK_TIME: 2000 
    restart: always 

    kafka: 
    image: confluentinc/cp-kafka:3.2.0 
    hostname: kafka 
    container_name: kafka 
    depends_on: 
     - zookeeper 
    ports: 
     - '9092:9092' 
    environment: 
     KAFKA_BROKER_ID: 1 
     KAFKA_ZOOKEEPER_CONNECT: 'zookeeper:2181' 
     KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://192.168.99.100:9092 
     LISTENERS: PLAINTEXT://0.0.0.0:9092 
    restart: always 

    kafka-rest: 
    image: confluentinc/cp-kafka-rest:3.2.0 
    container_name: kafka-rest 
    depends_on: 
    - kafka 
    ports: 
    - '8082:8082' 
    environment: 
    KAFKA_REST_ZOOKEEPER_CONNECT: 'zookeeper:2181' 
    KAFKA_REST_LISTENERS: http://kafka-rest:8082 
    KAFKA_REST_SCHEMA_REGISTRY_URL: http://schema-registry:8081 
    KAFKA_REST_HOST_NAME: kafka-rest 
    restart: always 

schema-registry: 
    image: confluentinc/cp-schema-registry:3.2.0 
    container_name: schema-registry 
    depends_on: 
    - kafka 
    ports: 
    - '8081' 
    environment: 
    SCHEMA_REGISTRY_KAFKASTORE_CONNECTION_URL: 'zookeeper:2181' 
    SCHEMA_REGISTRY_HOST_NAME: schema-registry 
    SCHEMA_REGISTRY_LISTENERS: http://schema-registry:8081 
    restart: always 

connect: 
    image: confluentinc/cp-kafka-connect:3.2.0 
    container_name: kafka-connect 
    depends_on: 
    - zookeeper 
    - kafka 
    - schema-registry 
    ports: 
    - "8083:8083" 
    restart: always 
    environment: 
    CONNECT_BOOTSTRAP_SERVERS: 'kafka:9092' 
    CONNECT_REST_ADVERTISED_HOST_NAME: connect 
    CONNECT_REST_PORT: 8083 
    CONNECT_GROUP_ID: compose-connect-group 
    CONNECT_CONFIG_STORAGE_TOPIC: docker-connect-configs 
    CONNECT_OFFSET_STORAGE_TOPIC: docker-connect-offsets 
    CONNECT_STATUS_STORAGE_TOPIC: docker-connect-status 
    CONNECT_KEY_CONVERTER: io.confluent.connect.avro.AvroConverter 
    CONNECT_KEY_CONVERTER_SCHEMA_REGISTRY_URL: http://schema-registry:8081 
    CONNECT_VALUE_CONVERTER: io.confluent.connect.avro.AvroConverter 
    CONNECT_VALUE_CONVERTER_SCHEMA_REGISTRY_URL: http://schema-registry:8081 
    CONNECT_INTERNAL_KEY_CONVERTER: org.apache.kafka.connect.json.JsonConverter 
    CONNECT_INTERNAL_VALUE_CONVERTER: org.apache.kafka.connect.json.JsonConverter 
    CONNECT_ZOOKEEPER_CONNECT: "zookeeper:2181" 

现在，我已经成功地通过正确设置正确曝光的卡夫卡容器我的非dockerized应用advertised.listener属性为PLAINTEXT：// {DOCKER_MACHINE_IP}：9092，但正如您所看到的，我还添加了其他融合应用程序来扩展我的Kafka设置（Kafka REST，Schema-Registry）。由于advertised.listener属性，这些不能再连接到我的Kafka实例。

我可以将其更改为正确的容器主机名 - > PLAINTEXT：// kafka：9092，但后来我失去了使用其他应用程序再次访问kafka实例的能力。有没有简单的方法可以解决这个问题？

Omar，也许你已经解决了你的问题，但为了将来的参考，Hans Jespersen的评论为我做了窍门，即使在Windows上。

作为管理员，打开C:\Windows\System32\drivers\etc\hosts并添加以下行以将kafka代理公开为localhost。 127.0.0.1 broker

而且我docker-compose.yml文件看起来如下：

--- 
version: '2' 
services: 
    zookeeper: 
    image: confluentinc/cp-zookeeper 
    hostname: zookeeper 
    extra_hosts: 
    - "moby:127.0.0.1" 
    ports: 
     - "2181:2181" 
    environment: 
     ZOOKEEPER_CLIENT_PORT: 2181 
     ZOOKEEPER_TICK_TIME: 2000 

    broker: 
    image: confluentinc/cp-kafka 
    hostname: broker 
    extra_hosts: 
    - "moby:127.0.0.1" 
    depends_on: 
     - zookeeper 
    ports: 
     - '9092:9092' 
    environment: 
     KAFKA_BROKER_ID: 1 
     KAFKA_ZOOKEEPER_CONNECT: 'zookeeper:2181' 
     KAFKA_ADVERTISED_LISTENERS: 'PLAINTEXT://broker:9092' 
     KAFKA_DEFAULT_REPLICATION_FACTOR: 1 

    schema_registry: 
    image: confluentinc/cp-schema-registry 
    hostname: schema_registry 
    # extra_hosts: 
    # - "moby:127.0.0.1" 
    depends_on: 
     - zookeeper 
     - broker 
    ports: 
     - '8081:8081' 
    environment: 
     SCHEMA_REGISTRY_HOST_NAME: schema_registry 
     SCHEMA_REGISTRY_KAFKASTORE_CONNECTION_URL: 'zookeeper:2181' 

    kafka-rest: 
    image: confluentinc/cp-kafka-rest 
    container_name: kafka-rest 
    extra_hosts: 
    - "moby:127.0.0.1" 
    depends_on: 
     - zookeeper 
     - broker 
    ports: 
     - '8082:8082' 
    environment: 
     KAFKA_REST_ZOOKEEPER_CONNECT: 'zookeeper:2181' 
     KAFKA_REST_LISTENERS: http://kafka-rest:8082 
     KAFKA_REST_SCHEMA_REGISTRY_URL: http://schema-registry:8081 
     KAFKA_REST_HOST_NAME: kafka-rest 

或者，（使用IPCONFIG/ALL）的作品太暴露我的笔记本电脑的当前IP地址，但其缺点是，每当网络的变化，我将不得不更改docker-compose.yml文件。
