Kubernetes 대시보드가 ​​작동하지 않고 "이미 존재합니다" 및 "요청된 리소스를 찾을 수 없습니다(서비스 힙스터 가져오기)"

나는 쿠버네티스를 처음 접한다

목표는 Kubernetes 클러스터 대시보드가 ​​작동하도록 하는 것입니다.

kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml --validate=false설명대로 하면여기

나는 얻다:

Error from server (AlreadyExists): error when creating "https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml": secrets "kubernetes-dashboard-certs" already exists
Error from server (AlreadyExists): error when creating "https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml": serviceaccounts "kubernetes-dashboard" already exists

내가 실행하면 kubectl get services --namespace kube-system다음을 얻습니다.

kube-dns               10.233.0.3      <none>        53/UDP,53/TCP   10d

대시보드 kubernetes 클러스터에 접근하려고 하면 다음과 같은 메시지가 나타납니다.Connection refused

대시보드를 작동시키려면 어떻게 해야 합니까? 당신의 도움을 주셔서 감사합니다.

답변1

먼저 모든 항목을 삭제합니다.

kubectl delete -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml

그런 다음 대시보드를 다시 만듭니다.

kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml

프록시를 시작합니다.

kubectl proxy

그런 다음 엽니다.

http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/

localhost 대신 k8s API 주소를 사용할 수도 있습니다. 일부 새 대시보드 버전에서는 ui예를 들어 다음과 같은 짧은 주소가 k8s.api.example.com/ui더 이상 작동하지 않으며 길고 보기 흉한 주소를 명시적으로 사용해야 합니다.
