Spring Cloud中的Zookeeper数据流保持断开连接

我试图用docker启动SCDF。它开始很好，但尝试部署任何流时，我的应用程序日志Spring Cloud中的Zookeeper数据流保持断开连接

我使用的是弹簧云数据流服务器本地-1.1.4遇到下面的错误。而在application.properties：

spring.cloud.dataflow.applicationProperties.stream.spring.cloud.zookeeper.connect-string=zookeeper:2181 
spring.cloud.dataflow.applicationProperties.stream.spring.cloud.stream.kafka.binder.brokers=kafka:9092

spring.cloud.dataflow.applicationProperties.stream.spring.cloud.stream.kafka.binder.offsetUpdateTimeWindow=15000

在随后的运行中我也得到

Caused by: kafka.common.KafkaException: fetching topic metadata for topics [Set(test2.transform)] from broker [List()] failed 
    at kafka.client.ClientUtils$.fetchTopicMetadata(ClientUtils.scala:72) ~[kafka_2.10-0.8.2.2.jar!/:na]

嗨，@ adrian-ber。当流应用程序无法查找和/或连接外部运行的kafka/zk群集时，通常会出现这种情况。您将提供主机/端口规格到SCDF服务器，并最终传播到所有应用程序 - 请参阅[这里]（http://docs.spring.io/spring-cloud-dataflow/docs/1.2。 0.M2 /参考/ htmlsingle /＃弹簧云数据流全局特性）。让我们从你的设置开始。你使用哪种SCDF服务器实现？版？你如何配置kafka/zk设置？ –

我更新了问题 –

我不知道为什么，但将码头图像zookeeper和wurstmeister/kafka:latest与spotify/kafka（同时包含Kafka和Zookeeper）替换为整个设置。

您的应用程序性能好看连接。您正在使用kafka和zookeeper作为特定主题的消息管道。该消息带有您需要配置的属性，可以在docker-compose文件（如果存在）或应用程序属性中进行配置。

例如，如果您的目标是服务充当消息的制作者。消息应该配置为主题和主题名称，如果有的话有组。这也可能是由于您的主题未被应用程序读取的代理设置不正确。

以下为买入卖出情况

spring.cloud.stream.kafka.bindings.costPrice.destination:abc.company.costPrice 

spring.cloud.stream.kafka.bindings.costPrice.content-type:application/json 

spring.cloud.stream.kafka.bindings.sellPrice.destination:abc.company.sellPrice 

spring.cloud.stream.kafka.bindings.sellPrice.content-type:application/json 
spring.cloud.stream.kafka.bindings.sellPrice.group:sellPriceGroup

的主题需要进行配置，以及卡夫卡课题申报。另请参阅网络端口是否可以让zookeeper和kafka运行。还要添加autoCreateTopics:true选项。

我没有意识到您当前的设置，如果您在读取application.properties之前正确启动zookeeper和kafka。你可以用machine-hostname：2181替换zookeeper：2181，对于kafka也是一样。（例如，pavan.network.co.in:2181）

希望它有帮助。
