  namespace: kube-system
---
kind: ClusterRoleBinding

  - kind: ServiceAccount
    name: dashboard-admin
    namespace: kube-system
roleRef:

  name: cluster-admin
  apiGroup: rbac.authorization.k8s.io

kubectl apply -f k8s-admin.yaml

2.获取name

kubectl get secret -n kube-system
NAME                                             TYPE                                  DATA   AGE
dashboard-admin-token-dhhmc                      kubernetes.io/service-account-token   3      69s
