我对Kafka完全陌生，我很难把它弄对。
我使用docker compose为docker设置了以下“wurstmeister/kafka docker”：

zookeeper:
 image: wurstmeister/zookeeper
 ports: 
   - "2181:2181"
kafka:
 image: wurstmeister/kafka
 ports:
   - "9092:9092"
 links: 
   - zookeeper:zk
 environment:
   KAFKA_ADVERTISED_HOST_NAME: 192.168.59.103
   # KAFKA_AUTO_CREATE_TOPCIS_ENABLE: 'true'
   KAFKA_CREATE_TOPICS: "events:1:1"
 volumes:
   - /var/run/docker.sock:/var/run/docker.sock

作为生产者和消费者，我使用的是ruby gem“kafka rb”。
制作人：

require 'kafka'
producer = Kafka::Producer.new({
    host: "192.168.59.103",
    port: 9092,
    topic: "events"
})

1000000.times do |i|
    message = Kafka::Message.new("Message #{i}")
    producer.push(message)
end

消费者：
需要“Kafka”

consumer = Kafka::Consumer.new({
    host: "192.168.59.103",
    port: 9092,
    topic: "events"
})

consumer.loop do |messages|
    puts "Received"
    puts messages
end

但我仍然收到拒绝连接或错误：

设置有什么根本性的问题吗？谢谢您
