我正在尝试使用kubeadm安装Kubernetes后创建一个水平pod自动缩放.

主要症状是kubectl get hpa将列中的CPU指标返回TARGETS为"undefined":

$ kubectl get hpa
NAME        REFERENCE              TARGETS           MINPODS   MAXPODS   REPLICAS   AGE
fibonacci   Deployment/fibonacci   <unknown> / 50%   1         3         1          1h

在进一步调查中,似乎hpa正在尝试从Heapster接收CPU指标 - 但在我的配置中,cpu指标由cAdvisor提供.

我根据以下输出做出这个假设kubectl describe hpa fibonacci:
