1、下载yaml文件进行部署

root@master-1:~# wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml

2、修改service的访问模式

root@master-1:~# vim recommended.yaml 

kind: Service
apiVersion: v1
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kubernetes-dashboard
spec:
  ports:
    - port: 443
      targetPort: 8443
  selector:
    k8s-app: kubernetes-dashboard
  type: NodePort     #修改为NodePort，没有就添加上

3、创建一个管理员用户

vim admin-user.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin-user
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: admin-user
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: admin-user
  namespace: kube-system

4、进行部署验证

kubectl apply -f recommended.yaml admin-user.yaml

#检查pod的状态
root@master-1:~# kubectl get po -n kubernetes-dashboard 
NAME                                         READY   STATUS    RESTARTS   AGE
dashboard-metrics-scraper-5cb4f4bb9c-m98c7   1/1     Running   0          35m
kubernetes-dashboard-6967859bff-q4plq        1/1     Running   0          35m

#查看service的配置（根据自己的端口访问）
root@master-1:~# kubectl get svc -n kubernetes-dashboard 
NAME                        TYPE        CLUSTER-IP    EXTERNAL-IP   PORT(S)         AGE
dashboard-metrics-scraper   ClusterIP   10.96.3.11    <none>        8000/TCP        36m
kubernetes-dashboard        NodePort    10.96.3.204   <none>        443:31859/TCP   36m

#生成token
root@master-1:~# kubectl create token admin-user -n kube-system

拿到token后登录验证
