데쉬보드에서 'Cluster-admin' not foud 로 12개 에러가 납니다.

Question

설치 영상 보고 따라 했는데.. 데쉬보드 페이지는 열리는데 노드와 네임스페이스 정보를 못읽어오네요. configmaps is forbidden: User "system:serviceaccount:kube-system:kubernetes-dashboard" cannot list resource "configmaps" in API group "" in the namespace "default": RBAC: clusterrole.rbac.authorization.k8s.io "Cluster-admin" not found close warning persistentvolumeclaims is forbidden: User "system:serviceaccount:kube-system:kubernetes-dashboard" cannot list resource "persistentvolumeclaims" in API group "" in the namespace "default": RBAC: clusterrole.rbac.authorization.k8s.io "Cluster-admin" not found close warning secrets is forbidden: User "system:serviceaccount:kube-system:kubernetes-dashboard" cannot list resource "secrets" in API group "" in the namespace "default": RBAC: clusterrole.rbac.authorization.k8s.io "Cluster-admin" not found close warning services is forbidden: User "system:serviceaccount:kube-system:kubernetes-dashboard" cannot list resource "services" in API group "" in the namespace "default": RBAC: clusterrole.rbac.authorization.k8s.io "Cluster-admin" not found close warning ingresses.extensions is forbidden: User "system:serviceaccount:kube-system:kubernetes-dashboard" cannot list resource "ingresses" in API group "extensions" in the namespace "default": RBAC: clusterrole.rbac.authorization.k8s.io "Cluster-admin" not found close warning daemonsets.apps is forbidden: User "system:serviceaccount:kube-system:kubernetes-dashboard" cannot list resource "daemonsets" in API group "apps" in the namespace "default": RBAC: clusterrole.rbac.authorization.k8s.io "Cluster-admin" not found close warning pods is forbidden: User "system:serviceaccount:kube-system:kubernetes-dashboard" cannot list resource "pods" in API group "" in the namespace "default": RBAC: clusterrole.rbac.authorization.k8s.io "Cluster-admin" not found close warning events is forbidden: User "system:serviceaccount:kube-system:kubernetes-dashboard" cannot list resource "events" in API group "" in the namespace "default": RBAC: clusterrole.rbac.authorization.k8s.io "Cluster-admin" not found close warning deployments.apps is forbidden: User "system:serviceaccount:kube-system:kubernetes-dashboard" cannot list resource "deployments" in API group "apps" in the namespace "default": RBAC: clusterrole.rbac.authorization.k8s.io "Cluster-admin" not found close warning replicasets.apps is forbidden: User "system:serviceaccount:kube-system:kubernetes-dashboard" cannot list resource "replicasets" in API group "apps" in the namespace "default": RBAC: clusterrole.rbac.authorization.k8s.io "Cluster-admin" not found close warning jobs.batch is forbidden: User "system:serviceaccount:kube-system:kubernetes-dashboard" cannot list resource "jobs" in API group "batch" in the namespace "default": RBAC: clusterrole.rbac.authorization.k8s.io "Cluster-admin" not found close warning cronjobs.batch is forbidden: User "system:serviceaccount:kube-system:kubernetes-dashboard" cannot list resource "cronjobs" in API group "batch" in the namespace "default": RBAC: clusterrole.rbac.authorization.k8s.io "Cluster-admin" not found close warning replicationcontrollers is forbidden: User "system:serviceaccount:kube-system:kubernetes-dashboard" cannot list resource "replicationcontrollers" in API group "" in the namespace "default": RBAC: clusterrole.rbac.authorization.k8s.io "Cluster-admin" not found close warning statefulsets.apps is forbidden: User "system:serviceaccount:kube-system:kubernetes-dashboard" cannot list resource "statefulsets" in API group "apps" in the namespace "default": RBAC: clusterrole.rbac.authorization.k8s.io "Cluster-admin" not found 아래 설정 부분이 잘못된 건가요?

안녕하세요! 제가 작성해놓은 아래 설치가이드를 보시면 https://kubetm.github.io/practice/appendix/installation_case2/ 6-2-1) Dashboard 설치 해당 설정은 교육목적으로 권한 설정을 모두 해제하는 방법이기 때문에 프로젝트에서 사용하실때는 이점 유의바래요 > https://github.com/kubernetes/dashboard kubectl apply -f https://kubetm.github.io/documents/appendix/kubetm-dashboard-v1.10.1.yaml 이렇게 Dashboard를 설치하게 되어 있습니다. 동영상은 예전버전이고 자료실에 내용이 계속 업데이트가 되기 때문에, 강의자료를 참고하시는게 좋고요. 위 내용을 봤을때 문제점은 name : Cluster-admin 에서 C가 대문자인게 문제로 보입니다. 감사합니다~!
