Какова правильная конфигурация сервера Eureka на Bluemix?

Я пытался следовать инструкциям по настройке микросервисов с помощью Spring и Bluemix, используя Eureka от Netflix для обнаружения сервисов. Bootstrap.yml следует инструкциям на странице spring.io/блог

Открытие не работает. Журнал ошибок времени выполнения имеет следующее:

Я чувствую, что в VCAP было какое-то обновление, поэтому я включаю его

Я столкнулся с этой проблемой при написании собственного сервера и клиентов eureka. Это связано с конфигурацией имени хоста клиента и serviceUrl. Он должен быть динамическим, чтобы его можно было разместить в облаке.

Вот пример моего сервера Eureka и клиента на IBM Bluemix.

Я использовал следующие переменные среды Cloud Foundry Environment, и это сработало

Для клиента Эврика

eureka:
  client:
    serviceUrl:
      defaultZone: http://eurekaregistry.mybluemix.net/eureka/
  instance:
    hostname: ${CF_INSTANCE_IP:localhost}
    nonSecurePort: ${CF_INSTANCE_PORT:${PORT:${server.port:8888}}}

Для сервера эврика

eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://eurekaregistry2.mybluemix.net/eureka/
