报错：
namespaces is forbidden: User “system:serviceaccount:kubernetes-dashboard:kubernetes-dashboard” cannot list resource “namespaces” in API group “” at the cluster scope
system:serviceaccount:kubernetes-dashboard:kubernetes-dashboard

events is forbidden: User “system:serviceaccount:kubernetes-dashboard:kubernetes-dashboard” cannot list resource “events” in API group “” in the namespace “default”

pods is forbidden: User “system:serviceaccount:kubernetes-dashboard:kubernetes-dashboard” cannot list resource “pods” in API group “” in the namespace “default”
如图：

原因：
serviceaccount kubernetes-dashboard 权限问题,源文件namespace与当前环境namespace不一致

解决：

kubectl create clusterrolebinding kubernetes-dashboard --clusterrole=cluster-admin --serviceaccount=kubernetes-dashboard:kubernetes-dashboard

也可采用yaml方式
[root@k8s-master1 ~]# cat ansible-install-k8s/roles/addons/files/dashboard-clusterrole.yaml

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: kubernetes-dashboard
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: kubernetes-dashboard
  namespace: kubernetes-dashboard

如果这条命令报错如：
