Python 引线不可用-docker容器

设置docker容器（kafka、zookeeper）并尝试从另一个容器（发布和）消费时，收到以下错误： KafkaError{code=LEADER\u不可用，val=5，str=“Broker:LEADER不可用”} 发布或使用时没有其他错误指示。使用

telnet 172.18.0.3 9092测试连接时，我收到了预期结果

始终尝试在KAFKA_播发的主机名中使用公共ip，您可以使用KAFKA_主机名指定实例的主机名

如果您使用的是最新的卡夫卡版本，使用listeners和Adverted.listeners，而不是使用host.name和Adverted.host.name。
1）您是否尝试过使用汇合Docker映像2）仅仅因为您可以telnet并且端口已打开并不意味着Kafka协议已被禁用functional@cricket_007不，我不熟悉融合的Docker图像。你有链接吗？感谢您在DockerHub的Confluent下，具体到wurstmeister的图片，您可以在这里查看我的答案：（以及其他提示）一般来说，广告的主机名应该可以从容器外部访问如果您向不存在的主题发送消息，您会收到此错误。请看这里：
