Cluster-autoscaler for CAPI create status configmap in the workload cluster

[jonathanbeber]

Which component are you using?:
cluster-autoscaler for Cluster API.

What version of the component are you using?:

Component version: v1.27.2

What k8s version are you using (kubectl version)?:

v1.27.4

What environment is this in?:
AWS managed by CAPA.

What did you expect to happen?:

The status configmap should be created in the cluster using the client resulted from the --cloud-config parameter.

What happened instead?:

The status configmap is created in the workload cluster.

How to reproduce it (as minimally and precisely as possible):

Deploy cluster-autoscaler with a topology as Autoscaler running in management cluster using service account credentials, with separate workload cluster and check that the status configmap is created in the workload cluster.

Anything else we need to know?:

I would like to work in this task.

The client used to write the configmap seems to come from https://github.com/kubernetes/autoscaler/blob/master/cluster-autoscaler/main.go#L392, set in line https://github.com/kubernetes/autoscaler/blob/master/cluster-autoscaler/main.go#L457 for AutoscalerOptions. That being said, as --cloud-config is not kubernetes client for other cloud providers, I believe there's no way for these change be just in the ClusterAPI provider.

thanks for reporting this, it sounds like this might be really difficult to fix from the capi provider.

perhaps we should start with a docs update so that users know the configmap will be created in the cluster specified by the --kubeconfig parameter?
