k8s-1.25.6部署dashboard

1、下载配置文件

wget https://gitee.com/qinziteng/K8S/raw/master/YMAL/recommended.yaml

防止资源404我再贴一便(在文档末尾！！！)

下载好后，apply执行

root@master01:~# 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
root@master01:~# kubectl get pods -n kubernetes-dashboard
NAME                                         READY   STATUS    RESTARTS   AGE
dashboard-metrics-scraper-64bcc67c9c-wtkzd   1/1     Running   0          36s
kubernetes-dashboard-66c887f759-ltcpz        1/1     Running   0          36s

2、自己手动暴露dashborad服务

vim kubernetes-dashboard-service.yaml
kind: Service
apiVersion: v1
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kubernetes-dashboard
spec:
  ports:
    - port: 443
      targetPort: 8443
  selector:
    k8s-app: kubernetes-dashboard
  type: NodePort

确认无误 apply执行

root@master01:~# kubectl apply -f kubernetes-dashboard-service.yaml
service/kubernetes-dashboard configured
root@master01:~# kubectl get svc -n kubernetes-dashboard
NAME                        TYPE        CLUSTER-IP    EXTERNAL-IP   PORT(S)         AGE
dashboard-metrics-scraper   ClusterIP   10.96.0.67    <none>        8000/TCP        4m54s
kubernetes-dashboard        NodePort    10.96.0.200   <none>        443:32477/TCP   4m54s

3、如果是k8s1.24版本以上包括1.24版本创建是不会自动创建token，需要手动创建一下，如下配置：

vim  dashboard-admin.yaml
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: admin
  annotations:
    rbac.authorization.kubernetes.io/autoupdate: "true"
roleRef:
  kind: ClusterRole
  name: cluster-admin
  apiGroup: rbac.authorization.k8s.io
subjects:
- kind: ServiceAccount
  name: admin
  namespace: kubernetes-dashboard
---
apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin
  namespace: kubernetes-dashboard
  labels:
    kubernetes.io/cluster-service: "true"
    addonmanager.kubernetes.io/mode: Reconcile

确认无误 apply执行

root@master01:~# kubectl apply -f dashboard-admin.yaml
clusterrolebinding.rbac.authorization.k8s.io/admin created
serviceaccount/admin created

root@master01:~# kubectl create token admin  --namespace kubernetes-dashboard
