我正在尝试使用 来启动和运行黑盒服务测试的基础设施docker-compose。我想在 Jenkins 上为多个服务执行此操作，因此有必要绑定到特定于构建的端口（例如 50012 而不是 9092），以便构建应该能够并行运行。

问题是，生成消息失败。

这是我的docker-compose.yml：

version: "3.4"

services:

  zookeeper:
    image: "confluentinc/cp-zookeeper:latest"
    ports:
      - "2181"
    environment:
      ZOOKEEPER_CLIENT_PORT: 2181
      ZOOKEEPER_TICK_TIME: 2000
    extra_hosts:
      - "moby:127.0.0.1"

  kafka:

      KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: INSIDE:PLAINTEXT,OUTSIDE:PLAINTEXT
      KAFKA_PROTOCOL_NAME: INSIDE
      KAFKA_ADVERTISED_PROTOCOL_NAME: OUTSIDE
      KAFKA_INTER_BROKER_LISTENER_NAME: INSIDE

      KAFKA_ADVERTISED_LISTENERS: "OUTSIDE://localhost:50012,INSIDE://kafka:9092"
      KAFKA_BROKER_ID: 1
      KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1
      KAFKA_ZOOKEEPER_CONNECT: "zookeeper:2181"
    ports:
      - "50012:9092"
    extra_hosts:
      - "moby:127.0.0.1"
    depends_on:
      - zookeeper

除了这个错误（我认为可以忽略）之外，我没有看到任何错误：

ERROR Could not submit metrics to Kafka topic __confluent.support.metrics: Failed to construct kafka producer (io.confluent.support.metrics.BaseMetricsReporter)

当我尝试像这样用 Kafka …
