k8s搭建kuboard-v3，手把手教你搭建-Toy模板网

这篇具有很好参考价值的文章主要介绍了k8s搭建kuboard-v3，手把手教你搭建。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

一、简介

今天部署kuboard是一个避坑的安装、使用教程，强烈建议将kuboard安装到master上。

kuboard官网：https://kuboard.cn/

二、kuboard部署

1、获取kuboard的yaml文件

这是华为云的镜像仓库替代 docker hub 分发 Kuboard 所需要的镜像

wget https://addons.kuboard.cn/kuboard/kuboard-v3-swr.yaml

2、修改kuboard-v3-swr.yaml

记得将nodeName: k8s-master改为自己的master的名称

🔹污点
Master一般默认作为调度节点，让其工作的话，将master作为node加入node：
kubectl taint nodes --all node-role.kubernetes.io/master-
🔸给master打上污点：NoSchedule：一定不能被调度
kubectl taint nodes k8s-master node-role.kubernetes.io/master=
🔸查看污点：
kubectl describe node k8s-master | grep Taints
🔸去掉污点：
kubectl taint nodes --all node-role.kubernetes.io/master-

3、创建kuboard

kubectl apply -f kuboard-v3-swr.yaml

4、查看创建情况

查看是否创建在master上，否者后期有很多问题。

watch kubectl get pod -n kuboard -o wide

5、访问UI界面

浏览器访问：http://masterIP:30080

账号：admin

密码：Kuboard123

三、kuboard使用

1、添加集群

有两种方式：1、导入集群的配置文件。2、安装agent端。

2、安装metrics-server和metrics-scraper（安装在master节点）

如果出现不在master节点上，就在kuboard界面找到对应的pod修改yaml文件。

在Deployment任务的第二个spec下增加一条强制pod运行在master上。
nodeName: k8s-master
(注意yaml文件格式！！)
