问题

1. 镜像下载失败

使用国内源：registry.cn-hangzhou.aliyuncs.com/google_containers

    spec:
      containers:
      - args:
        - --cert-dir=/tmp
        - --secure-port=4443
        - --kubelet-preferred-address-types=InternalIP,ExternalIP,Hostname
        - --kubelet-use-node-status-port
        - --metric-resolution=15s
        - --kubelet-insecure-tls
        image: registry.cn-hangzhou.aliyuncs.com/google_containers/metrics-server:v0.6.4
        imagePullPolicy: IfNotPresent

2. 遇到错误：metrics-server error because it doesn't contain any IP SANs

启动容器的命令增加参数--kubelet-insecure-tls

command:
- /metrics-server
- --kubelet-insecure-tls
