编写配置文件

创建配置文件存放目录并切换到其中：

mkdir /usr/local/kubernetes-dashboard
cd /usr/local/kubernetes-dashboard

执行如下指令，从官网获取配置文件：

kubectl apply -f 
https://raw.githubusercontent.com/kubernetes/
dashboard/v2.3.1/aio/deploy/recommended.yaml

由于官网在国外，如果下载不了可直接复制下面内容：

在官方给出的配置文件上新增下图所示配置，上面的配置文件标红的地方已加好如下配置。
在这里插入图片描述

安装kubernetes-dashboard

执行如下指令安装dashboard：

kubectl apply -f kubernetes-dashboard.yaml

通常情况下执行上面的指令，就可以安装成功。

查看是否在运行

kubectl get pod -n kubernetes-dashboard

创建访问账号

切换到如下目录并创建dash.yaml文件

cd /usr/local/kubernetes-dashboard
touch dash.yaml

将下面的配置内容添加到dash.yaml文件中

apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin-user
  namespace: kubernetes-dashboard
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: admin-user
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: admin-user
  namespace: kubernetes-dashboard

执行下面指令创建访问账号：

kubectl apply -f dash.yaml

在这里插入图片描述
查看token令牌

kubectl -n kubernetes-dashboard get secret $(kubectl -n kubernetes-dashboard get sa/admin-user -o jsonpath="{.secrets[0].name}") -o go-template="{{.data.token | base64decode}}"
