下载yaml文件到本地

wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.6.1/aio/deploy/recommended.yaml
mv recommended.yaml dashboardv2.6.1.ymal

修改dashboard service，更改service类型为NodePort，并暴露30110端口


spec:
  type: NodePort
  ports:
    - port: 443
      targetPort: 8443
      nodePort: 30110
  selector:

kubectl allpy -f dashboardv2.6.1.ymal

创建sa账户并绑定为cluster-admin的clusterrolebinding，1.24版本之前会自动生成绑定成功后的sa账户secret。新版需要手动创建

创建sa账户 admin

#切换 namespace
root@deploy:/dashboar# kubectl config set-context --namespace kubernetes-dashboard --current 
Context "context-cluster1" modified.

root@deploy:/dashboar# kubectl create serviceaccount admin
serviceaccount/admin created

将sa账户admin绑定到集群角色cluster-admin

root@deploy:/dashboar# kubectl create clusterrolebinding admin --clusterrole=cluster-admin --serviceaccount=kubernetes-dashboard:admin
clusterrolebinding.rbac.authorization.k8s.io/admin created

查看admin集群角色

kubectl get clusterrolebindings.rbac.authorization.k8s.io |grep admin

创建secret创建的用户token

root@deploy:/dashboar# vim usercrendentitals.yaml 
apiVersion: v1
kind: Secret
type: kubernetes.io/service-account-token
metadata:
  name: dashboard-admin-user
  namespace: kubernetes-dashboard 
  annotations:
    kubernetes.io/service-account.name: "admin"

root@deploy:/dashboar# kubectl apply -f usercrendentitals.yaml

获取secret创建的用户token

root@deploy:/dashboar# kubectl describe secrets dashboard-admin-user |grep token

kubectl describe secrets dashboard-admin-user |grep token
