예상되는 동작
Spring Cloud Kubernetes 설명서에 따르면 Spring 애플리케이션이 Pod에서 실행 중일 때 이를 감지하는 데 필요한 모든 것은 Spring Cloud Kubernetes를 spring-cloud-kubernetes-all의존성이 있는 클래스 경로에 추가하는 것입니다.
이렇게 하면 두 가지 이벤트가 트리거됩니다.
- 있는 경우
application-kubernetes.yml프로필이 로드됩니다. - Kubernetes 구현은
DiscoveryClientEureka의 기본값 대신 KubeDNS를 활용하여 서비스 검색에 사용됩니다.
그리고 여기:
실제 동작
다음 yaml을 사용하여 Spring Cloud Kubernetes 애플리케이션을 부팅하고 NodePort를 통해 액추에이터 엔드포인트에 액세스 한 후 폴더 에 a가 존재 http://minikube-ip:port/actuator/env하더라도 활성 프로필 세트가 없음을 확인했습니다 .application-kubernetes.ymlresources
{
"activeProfiles": [],
...
엔드포인트 에서 추가 조사를 해보니 다음 http://minikube-ip:port/actuator/info과 같이 Spring 애플리케이션이 팟(Pod)에 있다는 것을 전혀 인식하지 못하는 것을 볼 수 있습니다.
{
"kubernetes": {
"inside": false
}
