El panel de Kubernetes no funciona, "ya existe" y "no se pudo encontrar el recurso solicitado (obtener el montón de servicios)"

Soy nuevo en Kubernetes

El objetivo es hacer que el panel del clúster de Kubernetes funcione

Cuando hago kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml --validate=falselo descritoaquí

Yo obtengo:

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
Error from server (AlreadyExists): error when creating "https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml": roles.rbac.authorization.k8s.io "kubernetes-dashboard-minimal" already exists
Error from server (AlreadyExists): error when creating "https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml": rolebindings.rbac.authorization.k8s.io "kubernetes-dashboard-minimal" already exists

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

Cuando corro kubectl get services --namespace kube-system, obtengo:

NAME                   CLUSTER-IP      EXTERNAL-IP   PORT(S)         AGE
kube-dns               10.233.0.3      <none>        53/UDP,53/TCP   10d
kubernetes-dashboard   10.233.28.132   <none>        80/TCP          9d

Cuando intento acceder al clúster de Kubernetes del panel, apareceConnection refused

kubectl logs --namespace=kube-system kubernetes-dashboard-4167803980-1dz53producción:

¿Cómo puedo hacer que el panel funcione? Aprecio tu ayuda.

Primero borra todo:

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

Luego recrea el tablero:

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

Iniciar un proxy:

kubectl proxy

Luego ábrelo:

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

También puede usar su dirección API de K8s en lugar de localhost. Tenga en cuenta que en algunas versiones nuevas del panel, la dirección corta con, uipor ejemplo: k8s.api.example.com/uiya no funciona y debe usar la dirección larga y fea explícitamente.
