kubernetes autoscale与heapster有问题

Question

我已经在kubernetes上安装了heapster，我正在尝试自动缩放我的pod..但我一直看到以下几点：

unable to get metrics for resource cpu: unable to fetch metrics from resource metrics API: the server could not find the requested resource (get pods.metrics.k8s.io)

堆服务本身

我想让自动缩放与kubernetes一起工作，有人有什么想法吗？

我知道heapster已被弃用，但到目前为止，我无法更改或升级到metrics server。所以需要一些帮助

我曾经看到过类似的错误。问题是RBAC问题，但错误日志具有误导性。请确保您提供了对pods.metrics.k8s.io资源的get权限。

检查这个类似的问题：Kubernetes Custom CRD: “Failed to list …: the server could not find the requested resource”

注意:从Heapster获取指标是从Kubernetes1.11开始的deprecated。参考：Horizontal Pod Autoscaler
