Kubernetes 库伯内特斯自动标定

我的集群上安装了Kubernetes v1.12.1。 我从以下repo下载了metrics服务器：

然后运行以下命令：

kubectl create -f metrics-server/deploy/1.8+/

然后我尝试使用以下工具自动调整部署：

kubectl autoscale deployment example-app-tier --min 1 --max 3 --cpu-percent 70 --spacename example

但这里的目标显示未知/70%

kubectl get hpa --spacename example
NAMESPACE   NAME               REFERENCE                     TARGETS         MINPODS   MAXPODS   REPLICAS   AGE
example example-app-tier   Deployment/example-app-tier   <unknown>/70%   1         3         1          3h35m

因此，我正在寻找任何教程，帮助我使用metrics server或Prometheus逐步启用自动缩放（而不是Heapster，因为它已被弃用，不再受支持）

谢谢大家!

您需要向API服务器注册度量服务器，并确保它们能够通信

如果已经完成，您需要检查k8s版本中kubectl top命令的帮助，该命令可能默认使用heapster，您可能需要告诉它改用新服务

从help命令看，它似乎还没有被移植到新的metric服务器，默认情况下仍在寻找heapster

C02W84XMHTD5:tmp iahmad$ kubectl top node --help
Display Resource (CPU/Memory/Storage) usage of nodes. 

The top-node command allows you to see the resource consumption of nodes.

Aliases:
node, nodes, no

Examples:
  # Show metrics for all nodes
  kubectl top node

  # Show metrics for a given node
  kubectl top node NODE_NAME

Options:
      --heapster-namespace='kube-system': Namespace Heapster service is located in
      --heapster-port='': Port name in service to use
      --heapster-scheme='http': Scheme (http or https) to connect to Heapster as
      --heapster-service='heapster': Name of Heapster service
  -l, --selector='': Selector (label query) to filter on, supports '=', '==', and '!='.(e.g. -l
key1=value1,key2=value2)

Usage:
  kubectl top node [NAME | -l label] [options]

Use "kubectl options" for a list of global command-line options (applies to all commands).

注意：我使用的是1.10，可能在您的版本中，选项不同

因此，如果top命令以v1beta1.metrics.k8s.io的名称出现在apiservices列表中，我应该如何运行top命令使其链接到metrics服务器？
