Панель мониторинга Kubernetes не работает, "уже существует" и " не удалось найти запрошенный ресурс (получить службы heapster)"

Я новичок в Kubernetes

цель получить Kubernetes рабочая приборная панель кластера

когда я делаю kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml --validate=false как рассказали здесь

Я:

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": services "kubernetes-dashboard" already exists

когда я запускаю kubectl get services --namespace kube-system, Я:

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

при попытке добраться до панели мониторинга кластера kubernetes, я получаю Connection refused

kubectl logs --namespace=kube-system kubernetes-dashboard-4167803980-1dz53 выход:
