Kubernetes metrics服务器没有'；t提供所有指标或衡量HPA

按照这里的示例，我创建了installed metrics server，并对其进行了如下修改：

    spec:
      containers:
      - command:
        - metrics-server
        - --secure-port=8443
        - --kubelet-insecure-tls=true
        - --kubelet-preferred-address-types=InternalIP,ExternalIP,Hostname
        image: docker.io/bitnami/metrics-server:0.3.7-debian-10-r89
        imagePullPolicy: IfNotPresent
        name: metrics-server
        ports:
        - containerPort: 8443
          name: https
          protocol: TCP
        resources: {}

查询时会列出我的节点：

kubectl get --raw "/apis/metrics.k8s.io/v1beta1/nodes"
{"kind":"NodeMetricsList","apiVersion":"metrics.k8s.io/v1beta1","metadata":{"selfLink":"/apis/metrics.k8s.io/v1beta1/nodes"},"items":[{"metadata":{"name":"eo-test-metrics-35lks","selfLink":"/apis/metrics.k8s.io/v1beta1/nodes/eo-test-metrics-35lks","creationTimestamp":"2020-11-04T04:05:58Z"},"timestamp":"2020-11-04T04:05:28Z","window":"30s","usage":{"cpu":"770120208n","memory":"934476Ki"}},{"metadata":{"name":"eo-test-metrics-35lkp","selfLink":"/apis/metrics.k8s.io/v1beta1/nodes/eo-test-metrics-35lkp","creationTimestamp":"2020-11-04T04:05:58Z"},"timestamp":"2020-11-04T04:05:25Z","window":"30s","usage":{"cpu":"483763591n","memory":"850756Ki"}}]}

但是，HPA目标仍然“未知”：

kubectl get hpa
NAME REFERENCE TARGETS MINPODS MAXPODS REPLICAS AGE
php-apache Deployment/php-apache <unknown>/50% 1 10 1 31m

顶部吊舱返回错误

错误：指标不可用
：

 kubectl top pods
W1104 11:19:27.854485   62798 top_pod.go:266] Metrics not available for pod default/php-apache-d4cf67d68-blt2c, age: 13h1m51.854463s
error: Metrics not available for pod default/php-apache-d4cf67d68-blt2c, age: 13h1m51.854463s

这是Kubernetes服务器版本
v1.19.3
和metrics服务器版本
0.3.6

来自metrics服务器的日志

当Docker 19.03用于Kubernetes 1.19版时，该问题得到解决，与此上游问题相关：
