K8S的dashboard的部署

 网上有很多关于dashboard的部署，但是可能是时间太久远了，yaml文件运行之后不是镜像拉不下来就是各种运行报错，经过了多番尝试，我找到了一个比较合适的yaml分享给大家。

      这个dashboard的namespace是用的kubernetes-dashboard，如果你你想改成kube-system也可以的，不会有影响，这里的镜像我已经替大家替换过了

  image: kubernetesui/dashboard:v2.0.0-beta4   这个是一个私人的镜像

  vim dashboard.yaml

运行pod

kubectl apply -f  dashboard.yaml

查看pod的运行情况

kubectl get pods  -n kubernetes-dashboard
(base) [root@test-bd-k8s01 nfs]# kubectl get pods -n kube-system

node-exporter-46djx 1/1 Running 0 6d6h
node-exporter-nhfk2 1/1 Running 0 6d6h
prometheus-0 2/2 Running 0 2d4h

如果处于running状态，要在看一下他的log日志

kubectl logs  -f  kubernetes-dashboard-cdbc9547c-7sb2n -n kubernetes-dashboard

kubectl logs  -f  dashboard-metrics-scraper-fb986f88d-nd9d6  -n kubernetes-dashboard

如果两个日志里都没有报错在去查看一下端口号

kubectl get svc -n kube-system

(base) [root@test-bd-k8s01 nfs]# kubectl get svc -n kube-system
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
calico-typha ClusterIP 10.107.187.43 <none> 5473/TCP 20d
dashboard-metrics-scraper ClusterIP 10.99.80.90 <none> 8000/TCP 47h
kube-dns ClusterIP 10.96.0.10 <none> 53/UDP,53/TCP,9153/TCP 20d
kube-state-metrics ClusterIP 10.108.232.162 <none> 8080/TCP,8081/TCP 4d
kubernetes-dashboard NodePort 10.99.23.34 <none> 443:30001/TCP 47h
prometheus NodePort 10.103.233.151 <none> 9090:30090/TCP 2d4h

然后再看一下30001端口是否存在

(base) [root@test-bd-k8s01 nfs]# netstat -nlp |grep 30001
tcp6 0 0 :::30001 :::* LISTEN 3322/kube-proxy

以上工作都完成了说明基本上可以启动了

要用https://IP:30001   输入火狐浏览器

 

 获取token的步骤

 创建一个账户

vim k8s-admin.yaml

apiVersion: v1
kind: ServiceAccount

kind: ClusterRoleBinding

  apiGroup: rbac.authorization.k8s.io
kubectl get secret -n kube-system   |grep dashboard-admin    

kubectl apply -f k8s-admin.yaml

kubectl get secret -n kube-system |grep dashboard-admin

(base) [root@test-bd-k8s01 nfs]# kubectl get secret -n kube-system   |grep dashboard-admin

然后把获得的token复制到web页面中就完成了
