Kubernetes集群自动缩放器不起作用

Question

我已经为aws kube集群部署了cluster-autoscaler，现在它失败并出现以下错误。

W0411 03:07:37.393124 1 clusterstate.go:514] Failed to get nodegroup for dev-k8s-node-asg-230-i-089e4d2f163533989: Wrong id: expected format aws:////, got

autoscaler-configuration命令：

./cluster-autoscaler \
  --v=6 \
  --stderrthreshold=info \
  --cloud-provider=aws \
  --skip-nodes-with-local-storage=false \
  --expander=least-waste \
  --node-group-auto-discovery=asg:tag=k8s.io/cluster-autoscaler/enabled,kubernetes.io/cluster/dev 

我在自动缩放组中添加了以下标签，有人可以帮助我了解此错误。

您可以尝试创建cloud-config.conf并在其中插入KubernetesClusterTag，KubernetesClusterID和Zone属性。 请确认

--cloud-provider=aws 

存在于每个节点和kubelet命令行中，如果

--cloud-config=

指向cloud_config.conf的正确路径。
