Question

我已经在AKS上创建了Azure集群，并创建了一些部署。由于我的部署之一需要autoscaling，因此我已在其上启用了HPA，但它无法正常工作。它无法从指标服务器获取指标。低于错误。有人可以帮我吗？

首先，通过应用Metrics Server安装these YAML files。

验证安装是否成功：

kubectl get --raw=/apis/metrics.k8s.io/v1beta1

第二，确保部署中的所有容器都具有CPU资源请求：

apiVersion: apps/v1
kind: Deployment
<...>
    spec:
      containers:
      - image: foo
        name: foo
        resources:
          requests:
            cpu: 500m

第三，按照已经配置的方式配置Horizontal Pod Autoscaler并观察事件。

Kubernetes Autoscaler在Azure AKS上不起作用
