在PCF中的Docker – 无法通过AMQP（spring cloud bus）连接到rabbitmq

我在玩Pivotal cloudfoundry和docker。 目前，我有一个春季启动应用程序，这是一个configuration服务器客户端连同spring的cloudbus。 如果我使用cf push demo-application target/my-jar-file.jar直接推送到PCF，这将cf push demo-application target/my-jar-file.jar 。

我现在正在尝试打包我的应用程序作为docker容器，并推入到PCF与cf push demo2 -o rraghur/demo 。 PCF创build一个容器并部署它 – 但spring的云端不起作用。 弹簧configuration确实工作，因为我在日志中看到以下内容

 2016-11-30T22:23:58.771+05:30 [APP/0] [OUT] 2016-11-30 16:53:58.770 INFO 12 --- [ main] cccConfigServicePropertySourceLocator : Fetching config from server at: https://config-67936b3e-1626-46b6-8117-480654f34e49.local.pcfdev.io 2016-11-30T22:24:00.588+05:30 [APP/0] [OUT] 2016-11-30 16:54:00.587 INFO 12 --- [ main] cccConfigServicePropertySourceLocator : Located environment: name=demo-application, profiles=[production], label=null, version=45c09f139492055b3a023462c852b82ae0d396a4, state=null 

但是，我的应用程序似乎无法连接到绑定的rabbitmq insntance – exception如下：

考虑到所有的服务都是通过VCAP_SERVICES注入到PCF中的，我的想法是，无论应用程序是通过构build包还是Docker容器推送，服务的parsing/绑定都应该没有区别。此外， connection refused表示networking问题 -有什么关于docker的容器，在PCF中有不同的作用？

UPDATE

我cf ssh了两个版本的cf ssh并安装了amqp-utils 。 然后在springCloudBus交换机上echo $VCAP_SERVICES然后是amqp-spy ，等待我rest。 仍然不知道为什么春季引导会抛出连接拒绝！

Answer 1

@Raghu从你已经发布的日志看来，似乎活动configuration文件似乎没有包含“云”，这是重新configuration和绑定你的应用程序到rabbitmq服务的关键。
