Question

我在kubernetes上安装了heapster，我正在尝试自动缩放吊舱。.但我一直看到以下内容：

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)

heapster服务本身

我想使用kubernetes进行自动缩放，任何人有任何想法吗？

我知道不推荐使用heapster，但是到目前为止，我无法更改或升级到指标服务器..所以可以提供一些帮助

我曾经见过类似的错误。问题是RBAC问题，但错误日志具有误导性。确保您已经为get资源提供了pods.metrics.k8s.io权限。

请检查以下类似问题：Kubernetes Custom CRD: “Failed to list …: the server could not find the requested resource”

注意：从Kubernetes 1.11开始，从Heapster获取度量标准为deprecated。参考：Horizontal Pod Autoscaler
