安装步骤：

1. 点击进入dashboard 的 GitHub - kubernetes/dashboard: General-purpose web UI for Kubernetes clustershttps://github.com/kubernetes/dashboard

2. 查看当前k8s版本对应的dashboard版本，点击右边releases

3.  执行对应版本指令安装(我的k8s是v1.23)

 

执行下方指令安装：
kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.5.1/aio/deploy/recommended.yaml

 安装报错信息：

The connection to the server raw.githubusercontent.com was refused - did you specify the right host or port?

解决办法：

• 直接浏览器打开上述指令中的地址

https://raw.githubusercontent.com/kubernetes/dashboard/v2.5.1/aio/deploy/recommended.yaml 打开后其实是一个文本信息 

• 本地创建相同文件，复制浏览器中打开的内容 

vi recommended.yaml

•  执行下面指令重新安装

kubectl apply -f recommended.yaml

• 出现下面信息，即问题解决
