spring - Bluemix 上的 Spring Cloud Dataflow - Ticktock 示例错误

Question

我在 Cloud Foundry 上试验 Spring Cloud Data Flow（版本 1.0.0.M2）。具体来说，我正在使用 Bluemix 来完成我的任务。

我使用这些参考成功构建了 Cloud Foundry 服务器： https ://github.com/lshannon/spring-cloud-data-flow-demo

http://docs.spring.io/spring-cloud-dataflow-admin-cloudfoundry/docs/1.0.0.M2/reference/html/getting-started.html

我启动了服务器，连接了本地 shell，成功注册了默认处理器、接收器和源。

使用的环境变量($1,$2,$3,$4)是我的个人数据：

cf set-env $APP_NAME SPRING_CLOUD_DEPLOYER_CLOUDFOUNDRY_API_ENDPOINT https://api.eu-gb.bluemix.net 
cf set-env $APP_NAME SPRING_CLOUD_DEPLOYER_CLOUDFOUNDRY_ORGANIZATION $1
cf set-env $APP_NAME SPRING_CLOUD_DEPLOYER_CLOUDFOUNDRY_SPACE $2
cf set-env $APP_NAME SPRING_CLOUD_DEPLOYER_CLOUDFOUNDRY_DOMAIN eu-gb.mybluemix.net
cf set-env $APP_NAME SPRING_CLOUD_DEPLOYER_CLOUDFOUNDRY_SERVICES redis01,rabbit
cf set-env $APP_NAME SPRING_CLOUD_DEPLOYER_CLOUDFOUNDRY_USERNAME $3
cf set-env $APP_NAME SPRING_CLOUD_DEPLOYER_CLOUDFOUNDRY_PASSWORD $4
cf set-env $APP_NAME SPRING_CLOUD_DEPLOYER_CLOUDFOUNDRY_SKIP_SSL_VALIDATION false

我仔细检查了 Bluemix 实例中的那些变量，一切都是正确的。

然后我尝试使用 shell 重新创建基本流示例，即：

stream create luketicktock --definition "time | log" --deploy

外壳输出是：

Created and deployed new stream 'luketicktock'

但是，我看不到任何已部署的 Cloud Foundry 应用程序能够重现这样的流。

似乎数据流服务器未能向 Bluemix 请求访问令牌以创建流。我做错了什么吗？

谢谢你的支持！

在没有有效自签名证书的情况下部署到 Cloud Foundry 时，通常会观察到这种情况。如果这是在您的开发环境中，您可以通过以下方式跳过 SSL 验证。

cf set-env $APP_NAME SPRING_CLOUD_DEPLOYER_CLOUDFOUNDRY_SKIP_SSL_VALIDATION true

截至今天，Spring Cloud Data Flow “核心”位于 RC1，Cloud Foundry实现位于 M3。正如RC1 博客中所列出的那样，有一些新的改进以及术语更改，因此强烈建议升级到最新版本。
