autoscaler for cluster xxxxxx might already exists.

Hello i am having this issue to create a hcp cluster with autoscale enable

The resource on TF is already prepared. However, the autoscaler functionality is not yet available publicly for HCP
We plan to fully open the functionality, when the time comes TF will also be able to leverage the usage

Is this cluster_autoscaler feature the same that we see in the OCM UI when creating ROSA HCP?

[gdbranco]

@davivcgarcia No, this is a cluster autoscaler. That one currently in the UI is the autoscaling parameters for the initial instance pool for customer workload that you get when installing the cluster. The cluster autoscaler has many more options in comparison to min and max nodes

The configuration for instance pools is available through the machine pool resource

[davivcgarcia]

@gdbranco Do you have an example of how to setup the default worker machine pool autoscaling parameters at cluster creation? And what is the difference between the cluster autoscaler and the autoscaling parameters from the machine pools?
