Rancher + AWS EC2 -- Node Autoscaling

We are currently in the process of migrating from Kops to Rancher and have run into a bit of a snag. Kops handles autoscaling of nodegroups naively and there does not seem to be a comparable feature in Rancher. The cluster-autoscaler helm seems to be the solution but it requires that launch configurations and autoscaling groups already exist, whereas kops creates them automagically.

There doesn’t seem to be any documentation on how to create launch configurations/autoscaling groups for the Rancher-deployed node pools. Does anyone have any insight here? I’m hoping that there’s just some documentation that I can’t find…
