Hi! I am unable to auto-scale Kubernetes clusters. As I understand, it create a "cluster-autoscaler" deployment that decides whether to scale or not. However, it does not seem to work, since it logs multiple errors and warnings in the pod, even though it is a completely clean cluster. Normal scaling seems to work just fine. # Setup A "default" CloudStack setup running KVMs. ## Settings (relevant) - Cloud kubernetes service enabled **true** - Cloud kubernetes cluster experimental features enabled **true** - Cloud kubernetes cluster max size **50** The nodes uses the following service offering: - 2 CPU x 2.05 Ghz - 2048 MB memory - 8 GB root disk # Replicate 1. Create a new cluster using Kubernets 1.24 ISO found here: http://download.cloudstack.org/cks/ 2. Enable forced auto-scaling Since the cluster starts with only one worker node, auto-scaling with 3-5 nodes should trigger an upscale (I assume)  4. Check the logs for cluster-autoscaler in the Kubernetes cluster Some notable entries: ``` E0807 14:41:30.317148 1 reflector.go:138] k8s.io/client-go/informers/factory.go:134: Failed to watch *v1.CSIDriver: failed to list *v1.CSIDriver: csidrivers.storage.k8s.io is forbidden: User "system:serviceaccount:kube-system:cluster-autoscaler" cannot list resource "csidrivers" in API group "storage.k8s.io" at the cluster scope E0807 14:41:32.388828 1 reflector.go:138] k8s.io/client-go/informers/factory.go:134: Failed to watch *v1beta1.CSIStorageCapacity: failed to list *v1beta1.CSIStorageCapacity: csistoragecapacities.storage.k8s.io is forbidden: User "system:serviceaccount:kube-system:cluster-autoscaler" cannot list resource "csistoragecapacities" in API group "storage.k8s.io" at the cluster scope ``` Even though I have not edited anything myself, it is a clean CKS cluster ``` W0807 14:41:43.251280 1 clusterstate.go:590] Failed to get nodegroup for 6a4c91a3-9694-4596-9ddd-dc86e60136ff: Unable to find node 6a4c91a3-9694-4596-9ddd-dc86e60136ff in cluster W0807 14:41:43.251361 1 clusterstate.go:590] Failed to get nodegroup for bd0b855f-6dc6-4678-9bea-b52329333024: Unable to find node bd0b855f-6dc6-4678-9bea-b52329333024 in cluster I0807 14:57:06.667061 1 static_autoscaler.go:341] 2 unregistered nodes present ``` The entire log: [logs-from-cluster-autoscaler-in-cluster-autoscaler-5bf887ddd8-hxg2g.log](https://github.com/apache/cloudstack-kubernetes-provider/files/12281530/logs-from-cluster-autoscaler-in-cluster-autoscaler-5bf887ddd8-hxg2g.log) Please tell me if you need more logs to look at, or if I should try some other configuration.
