Hi
@dazzling-kitchen-36068 sorry for the delay. I really wanted to write some notes but ran out of time. You can use what is described here:
https://www.dbi-services.com/blog/rancher-autoscaler-enable-rke2-node-autoscaling/. Don't really care that is related to AWS.
One of the great things Rancher has is its own autoscaler provider, so that's what you configure. When a new node is needed, Rancher's autoscaler provider takes care of talking to the actual provider used in the cluster definition (VMWare, Azure, ...). That way, even if there's no official autoscaler provider for VMWare, you can still use it through Rancher's one.
I've personally tested all the steps described in the blog on my VMWare environment and it worked perfectly.
I'll keep the cluster I created for the tests up and running just in case you want to check anything. That way we can compare your environment and mine.
