一、dashboard配置

1、查看dashboard配置
#1、查看dashboard服务pod

[root@k8s-master01 ~]# kubectl get po -n kubernetes-dashboard -owide
NAME                                         READY   STATUS    RESTARTS   AGE   IP              NODE           NOMINATED NODE   READINESS GATES
dashboard-metrics-scraper-86bb69c5f6-5mbh5   1/1     Running   0          57m   172.169.92.65   k8s-master02   <none>           <none>
kubernetes-dashboard-6576c84894-snkjz        1/1     Running   0          57m   172.162.195.3   k8s-master03   <none>           <none>

#2、查看kubernetes-dashboard.service信息

[root@k8s-master01 ~]# kubectl get svc -n kubernetes-dashboard -owide
NAME                        TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)         AGE    SELECTOR
dashboard-metrics-scraper   ClusterIP   10.105.204.160   <none>        8000/TCP        147m   k8s-app=dashboard-metrics-scraper
kubernetes-dashboard        NodePort    10.103.63.205    <none>        443:32418/TCP   147m   k8s-app=kubernetes-dashboard

#3、更改为NodePort的方式就可以访问到dashboard
//注：NodePort就是在每个宿主机上去启动一个端口，这个端口就可以访问到对应的服务上
[root@k8s-master01 ~]# kubectl edit svc kubernetes-dashboard -n kubernetes-dashboard
   selector:
    k8s-app: kubernetes-dashboard
  sessionAffinity: None
  type: NodePort                  // 默认是NodePort；若不是可更改为NodePort 

#4、查看dashboard端口号

[root@k8s-master01 ~]# kubectl get svc -n kubernetes-dashboard -owide
NAME                        TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)         AGE    SELECTOR
dashboard-metrics-scraper   ClusterIP   10.105.204.160   <none>        8000/TCP        150m   k8s-app=dashboard-metrics-scraper
kubernetes-dashboard        NodePort    10.103.63.205    <none>        443:32418/TCP   150m   k8s-app=kubernetes-dashboard

~~~     查看是否自动创建管理员用户；若是没有需要手动创建管理员用户
~~~     # 查看是否生成管理原用户
~~~     已经创建了管理员用户；若是没有创建；依据以下方案进行手动创建

[root@k8s-master01 ~]# kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')

### --- 手动创建管理员用户
~~~     # 手动创建管理员用户配置文件

[root@k8s-master01 ~]# vim admin.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin-user
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding 
metadata: 
  name: admin-user
  annotations:
    rbac.authorization.kubernetes.io/autoupdate: "true"
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: admin-user
  namespace: kube-system

#1、手动创建管理员用户配置文件
[root@k8s-master01 ~]# vim admin.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin-user
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding 
metadata: 
  name: admin-user
  annotations:
    rbac.authorization.kubernetes.io/autoupdate: "true"
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: admin-user
  namespace: kube-system
#2、创建超级管理员用户
[root@k8s-master01 ~]# kubectl create -f admin.yaml -n kube-system
serviceaccount/admin-user created

三、登录dashboard；进入kubernetes-dashboard管理后台
