我想用docker启动scdf。它一开始很好，但是当尝试部署任何流时，我在应用程序日志中得到以下错误

我使用的是spring-cloud-dataflow-server-local-1.1.4。而且在 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

在随后的跑步中，我也会

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]

我不知道为什么但是替换docker图像 zookeeper 以及 wurstmeister/kafka:latest 与 spotify/kafka （包括Kafka和zookeeper）使整个设置工作。

您的应用程序属性看起来很适合连接。您正在使用kafka和zookeeper作为特定主题的消息管道。消息附带了您需要在docker compose文件（如果存在）或应用程序属性中配置的属性。
例如，如果您的目标是让服务充当消息的生产者。消息应配置为主题和主题名称，如果有，则包含组。这也可能是由于不正确的代理设置，应用程序无法读取主题。
以下是Kafka关于买卖场景的主题声明

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

主题也需要配置。还可以查看网络端口是否可以运行zookeeper和kafka。同时添加 autoCreateTopics:true 选项。
如果在读取application.properties之前正确启动zookeeper和kafka，我不知道您当前的设置。你不妨换个zookeeper:2181 with 机器-hostname:2181 ，Kafka也是(例如pavan.network.co.in:2181）
希望有帮助。
