一、下载安装dashboard

先下载recommend.yaml文件

wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.5.0/aio/deploy/recommended.yaml

[root@master dashboard]# wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.5.0/aio/deploy/recommended.yaml

二、修改相应的参数

修改recommended.yaml中的service类型，默认是clustip，外面访问不了，将其修改成nodeport

# 修改kubernetes-dashboard的Service类型
kind: Service
apiVersion: v1
metadata:labels:k8s-app: kubernetes-dashboardname: kubernetes-dashboardnamespace: kubernetes-dashboard
spec:type: NodePort  # 新增ports:- port: 443targetPort: 8443nodePort: 30009  # 新增selector:k8s-app: kubernetes-dashboard

# 部署
[root@master ~]# kubectl create -f recommended.yaml# 查看是否启动dashboard的pod，svc
[root@master dashboard]# kubectl get pod,svc -n kubernetes-dashboard
NAME                                             READY   STATUS    RESTARTS   AGE
pod/dashboard-metrics-scraper-799d786dbf-rc2hj   1/1     Running   0          76s
pod/kubernetes-dashboard-546cbc58cd-dl757        1/1     Running   0          76sNAME                                TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)         AGE
service/dashboard-metrics-scraper   ClusterIP   10.109.195.57   <none>        8000/TCP        76s
service/kubernetes-dashboard        NodePort    10.105.195.35   <none>        443:30009/TCP   76s# 我们可以看到kubernetes-dashboard 和 kubernetes-dashboard都启动起来了，并且处于running状态
# kubernetes-dashboard 是dashboard自己的命名空间

三、创建访问用户，获取token

# 创建账号
[root@master-1 ~]# kubectl create serviceaccount dashboard-admin -n kubernetes-dashboard# 授权
[root@master-1 ~]# kubectl create clusterrolebinding dashboard-admin-rb --clusterrole=cluster-admin --serviceaccount=kubernetes-dashboard:dashboard-admin# 获取账号token
[root@master ~]#  kubectl get secrets -n kubernetes-dashboard | grep dashboard-admin
dashboard-admin-token-mfs2w        kubernetes.io/service-account-token   3      2m35s[root@master dashboard]# kubectl describe secrets dashboard-admin-token-mfs2w -n kubernetes-dashboard
