Hi people nice to meet you all, one quick question. I've deployed rancher on Hetzner following this guide https://ranchermanager.docs.rancher.com/getting-started/quick-start-guides/deploy-rancher-manager/hetzner-cloud It has one master and one worker node, my question now is how to add additional node? I'm confident with Terraform, but nowhere is the number of worker nodes that should be spin up defined?
