		            		看来您的kube-dns pods 无法与您的kube-apiserver对话。 kube-apiserver上的端口443已被弃用一段时间。您的ConfigMap或配置文件使其指向<kube-master:443>。

您可以尝试使用--kube-master-url选项在kube-dns部署中覆盖它。像这样:
apiVersion: apps/v1
kind: Deployment
metadata:
  name: kube-dns
  namespace: kube-system
  labels:
    k8s-app: kube-dns
    kubernetes.io/cluster-service: "true"
    addonmanager.kubernetes.io/mode: Reconcile
spec:
  strategy:
    rollingUpdate:
      maxSurge: 10%
      maxUnavailable: 0
  selector:
    matchLabels:
      k8s-app: kube-dns
  template:
    metadata:
      labels:
        k8s-app: kube-dns
      annotations:
        scheduler.alpha.kubernetes.io/critical-pod: ''
    spec:
      tolerations:
      - key: "CriticalAddonsOnly"
        operator: "Exists"
      volumes:
      - name: kube-dns-config
        configMap:
          name: kube-dns
          optional: true
      containers:
      - name: kubedns
        image: gcr.io/google_containers/k8s-dns-kube-dns-amd64:1.14.7
        ...
        args:
        - --kube-master-url=https://<master-ip>:6443
        - --domain=cluster.local.
        - --dns-port=10053
        - --config-dir=/kube-dns-config
        - --v=2

您可以从以下输出中获取:
$ kubectl cluster-info
