在master节点部署

2.1 下载yml文件，地址GitHub - kubernetes/dashboard: General-purpose web UI for Kubernetes clusters

#查看各版本与k8s的兼容，选择相应版本，v2.6.0只兼容k8s v1.24；v2.4.0兼容k8s v1.20和v1.21

wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.4.0/aio/deploy/recommended.yaml

#下载yml文件，可更换其中的v2.6.0版本（目前最新版）

wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.6.0/aio/deploy/recommended.yaml

或

wget https://github.com/kubernetes/dashboard/blob/v2.6.0/aio/deploy/recommended.yaml

2.2 修改yam文件，service改为NodePort类型

在kind: Service段的spec下加type: NodePort 和nodePort: 30000（注意对齐）

#或创建服务后再用命令修改

kubectl patch svc kubernetes-dashboard -p '{"spec":{"type":"NodePort"}}' -n kubernetes-dashboard

2.3 创建服务

kubectl create -f recommended.yaml
或
kubectl apply -f recommended.yaml 

2.4 查看端口

kubectl get svc -n kubernetes-dashboard

#或者如下查看和修改

kubectl edit svc kubernetes-dashboard -n kubernetes-dashboard

service/kubernetes-dashboard edited

然后使用浏览器访问IP和端口

2.5 创建账号

wget https://raw.githubusercontent.com/cby-chen/Kubernetes/main/yaml/dashboard-user.yaml

#内容如下

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 

kubectl apply -f dashboard-user.yaml

创建token令牌

#查看令牌（v2.6.0查看不了）

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}}"

# token令牌如下是我的（v2.4.0长期有效，可复制保存好）
