1、下载recommended.yaml配置文件

1）根据自己安装的kubernetes版本安装适配的dashboard

        我安装的kubernetes是1.24.2版本的，需要安装v:2.6.1版本的dashboard 

2）下载地址：https://raw.githubusercontent.com/kubernetes/dashboard/v2.6.1/aio/deploy/recommended.yaml

3）可以直接用wget方式下载，也可以手动下载上传到服务器中；

2、修改配置文件

1）将名称空间改为kube-system（改不改都可，只要自己知道在哪个命名空间即可）

[root@kub-k8s-master ~] # sed -i '/namespace/ s/kubernetes-dashboard/kube-system/g' recommended.yaml

2）修改Service的类型

kind: Service
apiVersion: v1
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kubernetes-dashboard
spec:
  type: NodePort                #修改类型为NodePort，大概在40行
  ports:
    - port: 443
      nodePort: 31260                #添加nodePort端口
      targetPort: 8443
  selector:
    k8s-app: kubernetes-dashboard

3、拉取镜像

1）查看要拉取的镜像

[root@k8s-master ~]# cat recommended.yaml |grep image
          image: kubernetesui/dashboard:v2.6.1
          imagePullPolicy: Always           #提前拉取镜像需要改成ifNotPresent，不会重复拉取
          image: kubernetesui/metrics-scraper:v1.0.8

2）提前拉取镜像，可节省时间

4、应用配置文件并创建dashboard

1）应用recommended.yaml

[root@k8s-master ~]# kubectl apply -f recommended.yaml 
namespace/kubernetes-dashboard created
serviceaccount/kubernetes-dashboard created
service/kubernetes-dashboard created
secret/kubernetes-dashboard-certs created
secret/kubernetes-dashboard-csrf created
secret/kubernetes-dashboard-key-holder created
configmap/kubernetes-dashboard-settings created
role.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrole.rbac.authorization.k8s.io/kubernetes-dashboard created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
deployment.apps/kubernetes-dashboard created
service/dashboard-metrics-scraper created
deployment.apps/dashboard-metrics-scraper created

2）查看pod的状态确保dashboard已经部署成功

[root@k8s-master ~]# kubectl get pod -n kubernetes-dashboard
NAME                                         READY   STATUS    RESTARTS   AGE
dashboard-metrics-scraper-7c5f6dcf49-gsvxr   1/1     Running   0          33s
kubernetes-dashboard-78fdc69869-hqzzk        1/1     Running   0          33s

5、访问dashboard

1）查看service，访问端口为31260

[root@k8s-master ~]# kubectl get service -n kubernetes-dashboard
NAME                        TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)         AGE
dashboard-metrics-scraper   ClusterIP   10.107.136.107   <none>        8000/TCP        61m
kubernetes-dashboard        NodePort    10.102.22.176    <none>        443:31260/TCP   61m

2）浏览器输入https://masterIP:端口号访问即可；我的是https://192.168.22.139:31260，然后选择token登录

6、编写 dashboard-adminuser.yaml文件并应用

[root@k8s-master ~]# vim dashboard-adminuser.yaml

[root@k8s-master ~]# cat dashboard-adminuser.yaml 
apiVersion: v1
kind: ServiceAccount
metadata:
    name: admin-user
    namespace: kube-system
---
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: kube-system

[root@k8s-master ~]# kubectl apply -f dashboard-adminuser.yaml 
Warning: resource serviceaccounts/admin-user is missing the kubectl.kubernetes.io/last-applied-configuration annotation which is required by kubectl apply. kubectl apply should only be used on resources created declaratively by either kubectl create --save-config or kubectl apply. The missing annotation will be patched automatically.
serviceaccount/admin-user configured
Warning: resource clusterrolebindings/admin-user is missing the kubectl.kubernetes.io/last-applied-configuration annotation which is required by kubectl apply. kubectl apply should only be used on resources created declaratively by either kubectl create --save-config or kubectl apply.

clusterrolebinding.rbac.authorization.k8s.io/admin-user configured

#我已经创建过一次了，所以是configured

7、获取token并登录

[root@k8s-master ~]# kubectl create token admin-user  --namespace kube-system
