在 master 节点执行

本例 k8s 是 v1.22.0，对应的 dashboard 是 – 这个版本，具体去这里查看对应的版本 https://github.com/kubernetes/dashboard/releases

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

[root@master vagrant]# kubectl get pods -n kubernetes-dashboard
NAME                                         READY   STATUS    RESTARTS   AGE
dashboard-metrics-scraper-856586f554-4xbht   1/1     Running   0          24m
kubernetes-dashboard-67484c44f6-5m6h6        1/1     Running   0          24m

dashboard 默认的服务的类型是ClusterIP，不便于我们通过浏览器访问，因此需要改成NodePort型的

[root@master vagrant]# kubectl get svc --all-namespaces
NAMESPACE              NAME                        TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)                  AGE
default                kubernetes                  ClusterIP   10.1.0.1       <none>        443/TCP                  114m
kube-system            kube-dns                    ClusterIP   10.1.0.10      <none>        53/UDP,53/TCP,9153/TCP   113m
kubernetes-dashboard   dashboard-metrics-scraper   ClusterIP   10.1.112.227   <none>        8000/TCP                 3m39s
kubernetes-dashboard   kubernetes-dashboard        ClusterIP   10.1.2.145     <none>        443/TCP                  3m40s

# 删除
kubectl delete service kubernetes-dashboard --namespace=kubernetes-dashboard

创建配置文件

vim dashboard-svc.yaml
 
# 内容
kind: Service
apiVersion: v1
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kubernetes-dashboard
spec:
  type: NodePort
  ports:
    - port: 443
      targetPort: 8443
  selector:
    k8s-app: kubernetes-dashboard
 
 
# 执行
kubectl apply -f dashboard-svc.yaml

想要访问dashboard服务，就要有访问权限，创建kubernetes-dashboard管理员角色

vi dashboard-svc-account.yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  name: dashboard-admin
  namespace: kube-system
---
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: dashboard-admin
subjects:
  - kind: ServiceAccount
    name: dashboard-admin
    namespace: kube-system
roleRef:
  kind: ClusterRole
  name: cluster-admin
  apiGroup: rbac.authorization.k8s.io
 
 
# 执行
kubectl apply -f dashboard-svc-account.yaml

获取 token

[root@master1 ~]# kubectl get secret -n kube-system |grep admin|awk '{print $1}'
dashboard-admin-token-bwgjv
 
 
# 复制下面的 token,后面登陆的时候要用到
[root@master1 ~]# kubectl describe secret dashboard-admin-token-bwgjv -n kube-system|grep '^token'|awk '{print $2}'
