When executing aks-cluster-autoscaler.yml, I am seeing below exception.

unable to recognize "D:\dockerbuild\aks-cluster-autoscaler.yml": no matches for kind "Deployment" in version "extensions/v1"

any changes required for apiVersion?

This is about AKS cluster node auto scaling.

[jakaruna-MSFT]

@bob999c Please let us know the version of your AKS cluster

[bob999c]

AKS 1.11.2.

[lukenny]

try this apiVersion: extensions/v1beta1

[lukenny]

or apiVersion: apps/v1

[jakaruna-MSFT]

@bob999c Like @lukenny suggested we can use apiVersion: extensions/v1beta1.
Try with that and let us know. Meanwhile I will also deploy to my cluster and let you know the status.

[jakaruna-MSFT]

@sakthivetrivel I deployed a cluster-autoscaler with the yaml file from the document. Like @bob999c mentioned i got an error. I changed the API version for deployments from v1 to v1beta1. After that I was able to deploy the cluster-autoscaler. API version app/v1 also works.
I also see that recently all the v1beta1 versions are changed to v1.
Please investigate further and make changes in the document as appropriate.

[lukenny]

API app/v1 and v1/beta1 work for me but Im getting CrashLoopBackOff error

I even tried v1.3.3 no dice

[bob999c]

v1/beta1 worked fine. Thank you.

when status move to ready status?

[jakaruna-MSFT]

@bob999c Status should move to ready within minutes.
If its not, we need to look at the pods logs created by that deployment.
@bob999c @lukenny Please look at the pods logs.
I have deployed my autoscaler in kube-system namespace.

[jakaruna-MSFT]

@jpconnock The author of this page is no longer available for assignment.
We need to change the API version in the Yaml file. Please suggest.
