Cloud Foundry Service Registry（Eureka）未能实现Blue-Green部署＆amp;路线路径

我面临两个与在启用Spring Cloud Services的云代工厂部署微服务相关的问题。 首先，看来如果我部署一个带有CF路径路径的应用程序，如果只是无法注册。我部署了这样的应用程序：

cf push -p target/date-services-1.0.jar --hostname env5-date-services --route-path /v1 -f manifest.yml date-services-v1 清单看起来像这样：

applications:
- name: date-services-v1
  memory: 1024M
  instances: 1
  timeout: 180
  env:
    JBP_CONFIG_OPEN_JDK_MEMORY_CALCULATOR: "[memory_sizes: {metaspace: 180m}, memory_heuristics: {metaspace:  25}]"
  services:
  - rabbitmq
  - config-server
  - discovery
  - circuit-breaker
  - mysql

该应用程序由Eureka注册，但无法找到。如果我从Eureka仪表板打开链接，它将被翻译为：

http://example.com/v1:80/info
http://example.com/v1:80/date

此网址无法访问。其他应用程序尝试调用日期服务微服务并因“未找到404”而失败。如果我删除路径路径 - 从部署 - 一切都很好。

另一个问题是蓝绿色部署。

如果我将同一个jar部署到一个新的应用程序名称，例如date-services-GREEN，那么我在Eureka中失败了：

最终这些错误消失了，但是在完全蓝绿色之后，尤里卡的注册路线仍然指向绿色而不是原始路线。哪个是无法进入的。

以下是我正在运行的命令：

cf push -p artifact.jar --hostname ${ENV_NAME}-${HOST_NAME}-${VERSION_NUMBER}-GREEN  -f manifest.yml ${TARGET_JOB_NAME}-GREEN

cf map-route ${TARGET_JOB_NAME}-GREEN ${DOMAIN} --hostname ${ENV_NAME}-${HOST_NAME}-${VERSION_NUMBER}

cf delete-route ${DOMAIN} -f --hostname ${ENV_NAME}-${HOST_NAME}-${VERSION_NUMBER}-GREEN

cf rename ${TARGET_JOB_NAME}-GREEN ${TARGET_JOB_NAME}

在Eureka注册的最终网址是：

http://pcfdev01-date-services-sa-v1-green.cf.example.com/info

使用网址中的“绿色”，它根本不起作用。如果我从URL中删除“绿色”，则可以正常工作。

我尝试过Camden.SR6和Brixton SR7。 Spring Cloud Services是1.4.1.RELEASE。我相信CF环境中的运行时间是1.7。

感谢。

答案 0 :(得分：1)

您的环境中安装了哪个版本的Spring Cloud Services磁贴？要在同一空间中进行蓝绿色部署的应用程序，您必须使用1.2或更高版本，请参阅http://docs.pivotal.io/spring-cloud-services/1-2/security-overview.html#service-registry-virtual-hostname-ownership。该部分讨论了PCF安装中的应用程序，但在PCF中，您可以将多个应用程序注册为相同的Eureka appname /虚拟主机名，但前提是它们都在同一空间中。

关于基于路径的路由的第一个问题，它与开箱即用的Eureka不兼容。该应用程序将注册主机名+路径（取自vcap.application.uris），此值将进入注册表中的主机名字段。功能区不期望这样：https://github.com/Netflix/ribbon/blob/v2.2.2/ribbon-loadbalancer/src/main/java/com/netflix/loadbalancer/LoadBalancerContext.java#L572您可以尝试在此处覆盖该行为：https://github.com/spring-cloud/spring-cloud-netflix/blob/v1.3.0.RC1/spring-cloud-netflix-core/src/main/java/org/springframework/cloud/netflix/ribbon/RibbonLoadBalancerContext.java

另一种方法可能是使用Zuul将/ v1和/ v2映射到正确的Eureka应用程序，并使用不同的名称注册/ v1和/ v2应用程序。
