如何使用 docker 图像 confluentinc/cp-kafka 创建 Kafka 生产者和控制台消费者？

Question

我想测试我正在为其创建的管道，我需要设置一个三节点 Kafka 集群，为了进行测试，我希望能够创建一个 kafka 主题和 kafka 控制台消费者，以查看是否信息是否通过。

问题是在用 confluentinc/cp-kafka 图像创建的容器内我找不到 /opt（或任何其他 file/directory）内的任何文件来创建主题或控制台消费者。

这是我正在使用的 docker-compose 文件：

version: '2.1'

services:
  zoo1:
    image: confluentinc/cp-zookeeper:7.0.1
    hostname: zoo1
    container_name: zoo1
    ports:
      - "2181:2181"
    environment:
      ZOOKEEPER_CLIENT_PORT: 2181
      ZOOKEEPER_SERVER_ID: 1
      ZOOKEEPER_SERVERS: zoo1:2888:3888

      KAFKA_ALLOW_EVERYONE_IF_NO_ACL_FOUND: "true"
    depends_on:
      - zoo1


  kafka3:
    image: confluentinc/cp-kafka:7.0.1
    hostname: kafka3
    container_name: kafka3
    ports:
      - "9094:9094"
    environment:
      KAFKA_ADVERTISED_LISTENERS: LISTENER_DOCKER_INTERNAL://kafka3:19094,LISTENER_DOCKER_EXTERNAL://${DOCKER_HOST_IP:-127.0.0.1}:9094

    depends_on:
      - zoo1

你能给我指出正确的方向吗？

Answer 1

脚本都在容器的 PATH 中，例如运行 kafka-topics 单独存在。

如果您想知道文件路径，请使用which kafka-topics
