我尝试使用Netflix的Eureka按照使用Spring和Bluemix设置微服务的说明来发现服务。 bootstrap.yml遵循spring.io/blog
中的说明这一发现无效。运行时错误日志具有以下内容：

我的感觉是VCAP中有一些更新，所以我把它包括在内

我在编写自己的eureka服务器和客户端时遇到了这个问题。这是因为客户端主机名和serviceUrl的配置。它必须是动态的才能托管在云上
以下是我在IBM Bluemix上运行我的Eureka服务器和客户端的示例
我使用了以下Cloud Foundry Environment变量并且它有效
eureka:
client:
serviceUrl:
defaultZone: http://eurekaregistry.mybluemix.net/eureka/
instance:
hostname: ${CF_INSTANCE_IP:localhost}
nonSecurePort: ${CF_INSTANCE_PORT:${PORT:${server.port:8888}}}
eureka:
client:
registerWithEureka: false
fetchRegistry: false
serviceUrl:
defaultZone: http://eurekaregistry2.mybluemix.net/eureka/
