k8s安装metrics-server显示running，但是kubectl top报错

Question

问题遇到的现象和发生背景

kubeadm部署的k8s集群中安装metrics-server显示running，但是kubectl top报错

kubectl get ndoes

kubectl version

metrics-server的status已经running了

问题相关代码，请勿粘贴截图

    spec:
      containers:
      - args:
        - --cert-dir=/tmp
        - --secure-port=4443
        - --kubelet-preferred-address-types=InternalIP
        - --kubelet-use-node-status-port
        - --metric-resolution=15s
        - --kubelet-insecure-tls

components.yaml文件中增加了--kubelet-insecure-tls

运行结果及报错内容

$ kubectl describe apiservice v1beta1.metrics.k8s.io
......

1. curl https://10.244.1.55:4430/apis/metrics.k8s.io/v1beta1 换个端口？
