10.1 部署Dashboard
下载yaml
修改kubernetes-dashboard的Service类型
部署
查看namespace下的kubernetes-dashboard下的资源
- 10.2 使用DashBoard

之前在kubernetes中完成的所有操作都是通过命令行工具kubectl完成的。其实，为了提供更丰富的用户体验，kubernetes还开发了一个基于web的用户界面（Dashboard）。用户可以使用Dashboard部署容器化的应用，还可以监控应用的状态，执行故障排查以及管理kubernetes中各种资源。

10.1 部署Dashboard

下载yaml，并运行Dashboard ```shell
下载yaml
[root@k8s-master01 ~]# wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0/aio/deploy/recommended.yaml

修改kubernetes-dashboard的Service类型

kind: Service apiVersion: v1 metadata: labels: k8s-app: kubernetes-dashboard name: kubernetes-dashboard namespace: kubernetes-dashboard spec: type: NodePort # 新增 ports:

- port: 443
  targetPort: 8443
  nodePort: 30009  # 新增

selector: k8s-app: kubernetes-dashboard

部署

[root@k8s-master01 ~]# kubectl create -f recommended.yaml

查看namespace下的kubernetes-dashboard下的资源

[root@k8s-master01 ~]# kubectl get pod,svc -n kubernetes-dashboard NAME READY STATUS RESTARTS AGE pod/dashboard-metrics-scraper-c79c65bb7-zwfvw 1/1 Running 0 111s pod/kubernetes-dashboard-56484d4c5-z95z5 1/1 Running 0 111s

NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE service/dashboard-metrics-scraper ClusterIP 10.96.89.218 8000/TCP 111s service/kubernetes-dashboard NodePort 10.104.178.171 443:30009/TCP 111s


2）创建访问账户，获取token
```shell
# 创建账号
[root@k8s-master01-1 ~]# kubectl create serviceaccount dashboard-admin -n kubernetes-dashboard
# 授权
[root@k8s-master01-1 ~]# kubectl create clusterrolebinding dashboard-admin-rb --clusterrole=cluster-admin --serviceaccount=kubernetes-dashboard:dashboard-admin
# 获取账号token
[root@k8s-master01 ~]#  kubectl get secrets -n kubernetes-dashboard | grep dashboard-admin
dashboard-admin-token-xbqhh        kubernetes.io/service-account-token   3      2m35s
[root@k8s-master01 ~]# kubectl describe secrets dashboard-admin-token-xbqhh -n kubernetes-dashboard
