Spring Cloud中的Zookeeper數據流保持斷開連接

我試圖用docker啓動SCDF。它開始很好，但嘗試部署任何流時，我的應用程序日誌Spring Cloud中的Zookeeper數據流保持斷開連接

我使用的是彈簧雲數據流服務器本地-1.1.4遇到下面的錯誤。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.zkNodes=zookeeper:2181 
spring.cloud.dataflow.applicationProperties.stream.spring.cloud.stream.kafka.binder.offsetUpdateTimeWindow=15000

在隨後的運行中我也得到

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。當流應用程序無法查找和/或連接外部運行的kafka/zk羣集時，通常會出現這種情況。您將提供主機/端口規格到SCDF服務器，並最終傳播到所有應用程序 - 請參閱[這裏]（http://docs.spring.io/spring-cloud-dataflow/docs/1.2。 0.M2 /參考/ htmlsingle /＃彈簧雲數據流全局特性）。讓我們從你的設置開始。你使用哪種SCDF服務器實現？版？你如何配置kafka/zk設置？ –

我更新了問題 –

我不知道爲什麼，但將碼頭圖像zookeeper和wurstmeister/kafka:latest與spotify/kafka（同時包含Kafka和Zookeeper）替換爲整個設置。

您的應用程序性能好看連接。您正在使用kafka和zookeeper作爲特定主題的消息管道。該消息帶有您需要配置的屬性，可以在docker-compose文件（如果存在）或應用程序屬性中進行配置。

例如，如果您的目標是服務充當消息的製作者。消息應該配置爲主題和主題名稱，如果有的話有組。這也可能是由於您的主題未被應用程序讀取的代理設置不正確。

以下爲買入賣出情況

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

的主題需要進行配置，以及卡夫卡課題申報。另請參閱網絡端口是否可以讓zookeeper和kafka運行。還要添加autoCreateTopics:true選項。

我沒有意識到您當前的設置，如果您在讀取application.properties之前正確啓動zookeeper和kafka。你可以用machine-hostname：2181替換zookeeper：2181，對於kafka也是一樣。（例如，pavan.network.co.in:2181）

希望它有幫助。
