安装kubernetes仪表板时找不到资源

Question

我正在使用以下命令安装kubernetes仪表板：

[root@iZuf63refzweg1d9dh94t8Z ~]# kubectl create -f kubernetes-dashboard.yaml
secret/kubernetes-dashboard-certs created
serviceaccount/kubernetes-dashboard created
role.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
deployment.apps/kubernetes-dashboard created
service/kubernetes-dashboard created

这是我的kubernetes yaml配置：

kind: Deployment
apiVersion: apps/v1
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kube-system
spec:
  replicas: 1
  revisionHistoryLimit: 10
  selector:
    matchLabels:
      k8s-app: kubernetes-dashboard
  template:

      labels:

    spec:
      containers:
      - name: kubernetes-dashboard
        image: registry.cn-beijing.aliyuncs.com/minminmsn/kubernetes-dashboard:v1.10.1
        ports:
        - containerPort: 8443
          protocol: TCP
        args:
          - --auto-generate-certificates
          # Uncomment the following line to manually specify Kubernetes API server Host
          # If not specified, Dashboard will attempt to auto discover the API server and connect
          # to it. Uncomment only if the default does not work.
          # - --apiserver-host=http://my-address:port
        volumeMounts:
        - name: kubernetes-dashboard-certs
          mountPath: /certs
          # Create on-disk volume to store exec logs
        - mountPath: /tmp
          name: tmp-volume
        livenessProbe:
          httpGet:
            scheme: HTTPS
            path: /
            port: 8443
          initialDelaySeconds: 30
          timeoutSeconds: 30
      volumes:
      - name: kubernetes-dashboard-certs
        secret:
          secretName: kubernetes-dashboard-certs
      - name: tmp-volume
        emptyDir: {}
      serviceAccountName: kubernetes-dashboard
      # Comment the following tolerations if Dashboard must not be deployed on master
      tolerations:
      - key: node-role.kubernetes.io/master
        effect: NoSchedule

---
# ------------------- Dashboard Service ------------------- #

kind: Service
apiVersion: v1
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kube-system
spec:
  type: NodePort
  ports:
    - port: 443
      targetPort: 8443
  selector:
    k8s-app: kubernetes-dashboard

获取结果：

[root@iZuf63refzweg1d9dh94t8Z ~]# kubectl get svc -n kube-system
NAME                   TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)         AGE
kube-dns               ClusterIP   10.43.0.10       <none>        53/UDP,53/TCP   102d
kubernetes-dashboard   NodePort    10.254.180.117   <none>        443:31720/TCP   58s
metrics-server         ClusterIP   10.43.96.112     <none>        443/TCP         102d

[root@iZuf63refzweg1d9dh94t8Z ~]# kubectl get pods -n kube-system
No resources found.

但当我检查端口31720时：

lsof -i:31720

输出是empty.Is服务部署成功吗？如何查看部署日志？为什么端口绑定不成功？

它使用自己的命名空间- "kubernetes-dashboard“。因此，只需使用kubectl get all -n kubernetes-dashboard即可查看所有内容
