安装dashboard

k8s-1.25.0对应dashboard版本为v2.7.0，查看合适版本。

找到合适版本后apply，执行指令后可以看到新增的内容。

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml

新增的内容

修改service/kubernetes-dashboard的暴露服务类型为NortPort

这时候访问暴露的dashboard端口能看到，需要使用token登录。

创建dashboard管理用户

cat > dashboard-svc-account.yaml <<-EOF
apiVersion: v1
kind: ServiceAccount
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: dashboard-admin
  namespace: kubernetes-dashboard
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: dashboard-admin-cluster-role
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
  - kind: ServiceAccount
    name: dashboard-admin
    namespace: kubernetes-dashboard
EOF
kubectl apply -f dashboard-svc-account.yaml

生成token后填入登录即可看到界面。kubectl -n kubernetes-dashboard create token dashboard-admin
