[SPRING] Zuul은 kubernetes에서 서비스로 트래픽을 라우팅 할 수 없습니다.
SPRINGZuul은 kubernetes에서 서비스로 트래픽을 라우팅 할 수 없습니다.
Zuul과 Eureka가 모두 kubernetes 클러스터에 있습니다. Zuul은 Eureka에 등록되어 있습니다.
"Resource-Service"라는 새로운 서비스를 시작합니다.이 서비스가 올바르게 부팅되어 Eureka에 등록하면 모든 서비스가 작동합니다.
"Resource-service"에 액세스하기 위해 Zuul 엔드 포인트를 치려고 할 때 다음 오류가 발생합니다. Zuul이 리소스 서비스가 eureka에 등록되어 있어도 리소스 서비스에 매핑 할 수없는 것처럼 보입니다.
그렇다면 zuul은 유레카 등록 서비스를 통해서가 아니라면 "Resource-service"에 대한 요청을 어디로 라우팅해야하는지 어떻게 알 수 있습니까?
참고 : Docker-compose를 사용하여이 작업을 시도 했으므로 zuul 및 eureka와 상호 작용하는 kubernetes가 있어야합니다.

해결법

==============================
1.Zuul에 등록 된 호스트 이름과 k8에서 서비스가 도달 할 수있는 호스트 이름이 일치하지 않는 것 같습니다. kubectl 서비스를 통해 K8 서비스의 이름을 찾으십시오. Zuul은 eureka에서 등록 된 이름을 얻을 것입니다 (이름을 등록하고 IP가 아닌 것 같습니다). k8s yaml에서 리소스 서비스가 'resource-service'가되도록 서비스 이름을 변경하면 제대로 작동 할 것으로 기대됩니다.

귀하의 도커 작성에서 나는 당신이 자원 서비스를 정의하는 섹션을 가지고 있으며 아마도 자원 서비스라고 명명 될 것이라고 기대한다. k8에 해당하는 것은 특정 배포의 포드와 일치하는 서비스의 이름입니다.
편집 : 기본적으로 스프링 부트 응용 프로그램은 eureka에 Pod의 호스트 이름 (IP를 사용하지 않는 경우)을 등록합니다. 따라서이를 대체하려면 서비스 이름과 일치하도록 eureka.instance.hostname을 설정해야합니다.

3.Zuul이 Eureka에 등록한다는 사실은 Zuul을 Eureka의 고객으로 만듭니다.
Zuul이 Eureka에 등록한다는 사실은 Zuul을 Eureka의 고객으로 만듭니다.
server.port=8762 spring.application.name=zuul-server eureka.instance.preferIpAddress=true eureka.client.registerWithEureka=true **eureka.client.fetchRegistry=true** eureka.client.serviceUrl.defaultZone=${EUREKA_URI:http://localhost:8761/eureka}fetchRegistry 속성은 (Eureka의 클라이언트로서) Zuul이 레지스트리 디렉토리, 즉 Eureka에 등록 된 서비스 목록을 가져올 수있게합니다.
Zuul 서버가 가동되면 http : // localhost : 8762 / routes url을 사용하여 열려있는 경로를 볼 수 있습니다.
이 루트는 가져온 레지스트리 및 관련 서비스 ID를 통해 Zuul에 의해 작성되었습니다. Zuul 응용 프로그램 속성에서 각 서비스 ID를 구성하여 원하는 방식으로 모든 서비스 ID의 경로를 변경할 수 있습니다.
zuul.routes.student-service.path=/student-api/** zuul.routes.student-service.serviceId=STUDENT-SERVICE또한 바람직한 방법은 호스트 이름이 아닌 IP에 의존하는 것입니다. 다른 응답에서 다른 사람들이 제안한 바와 같이 preferIpAddress 속성을 사용하십시오.
