UI界面部署

在master01上操作

#创建dashborad工作目录
[root@localhost k8s]# mkdir dashboard
[root@localhost dashboard]# ls
dashboard-configmap.yaml   dashboard-rbac.yaml    dashboard-service.yaml
dashboard-controller.yaml  dashboard-secret.yaml  k8s-admin.yaml
#组件创建
[root@localhost dashboard]# kubectl create -f dashboard-rbac.yaml 
role.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
[root@localhost dashboard]# kubectl create -f dashboard-secret.yaml 
secret/kubernetes-dashboard-certs created
secret/kubernetes-dashboard-key-holder created
[root@localhost dashboard]# kubectl create -f dashboard-configmap.yaml 
configmap/kubernetes-dashboard-settings created
[root@localhost dashboard]# kubectl create -f dashboard-controller.yaml 
serviceaccount/kubernetes-dashboard created
deployment.apps/kubernetes-dashboard created
[root@localhost dashboard]# kubectl create -f dashboard-service.yaml 
service/kubernetes-dashboard created

完成后查看创建在指定的kube-system命名空间下

[root@localhost dashboard]# kubectl get pods -n kube-system
NAME                                    READY   STATUS              RESTARTS   AGE
kubernetes-dashboard-65f974f565-jzcs9   0/1     ContainerCreating   0          12s

查看如何访问

[root@localhost dashboard]# kubectl get pods,svc -n kube-system
NAME                                        READY   STATUS    RESTARTS   AGE
pod/kubernetes-dashboard-65f974f565-jzcs9   1/1     Running   0          34s

NAME                           TYPE       CLUSTER-IP   EXTERNAL-IP   PORT(S)         AGE
service/kubernetes-dashboard   NodePort   10.0.0.154   <none>        443:30001/TCP   24s

访问nodeIP就可以访问

生成令牌

[root@localhost dashboard]# kubectl create -f k8s-admin.yaml 
serviceaccount/dashboard-admin created

//保存
[root@localhost dashboard]# kubectl get secret -n kube-system
