问题：
Spring Cloud Kubernetes应用程序在pod中运行时不检测
束高雅
预期行为
根据Spring Cloud Kubernetes文档，对于Spring应用程序来说，检测它何时在pod中运行所需的全部工作就是使用spring-cloud-kubernetes-all依赖项将Spring Cloud Kubernetes添加到类路径中。
这会触发两个事件：
-
null
https://cloud.spring.io/spring-cloud-static/spring-cloud-kubernetes/1.1.0.release/reference/html/#discoveryclient-for-kubernetes
实际行为
使用以下yaml引导Spring Cloud Kubernetes应用程序并通过NodePort访问其位于http://minikube-ip:port/actuator/env的actuatorendpoint后，我看到没有活动配置文件集，尽管resources文件夹中存在application-kubernetes.yml：
{
"activeProfiles": [],
...
通过对http://minikube-ip:port/actuator/infoendpoint的进一步研究，我发现Spring应用程序根本不知道它在pod中，这可以从以下几个方面得到证明：
{
"kubernetes": {
"inside": false
}
}

您确定您的application.yml中应该有spring.cloud.kubernetes.enabled=false吗？如果我正确理解文档，您需要将其保留为默认值(true)，以便它进行检测并加载Kubernetes概要文件。
如果禁用它，它将永远不会加载您的应用程序-kubernetes.yaml，因此在该文件中将其设置为true不会产生任何影响。
据我所知，您可以在主YAML中关闭kubernetes特性（例如spring.cloud.kubernetes.config.enabled=false)，但如果您希望配置文件自动配置工作，则不能关闭整个k8s集成。
