AgitatedDove14 since this is a powerful feature, I think this should be documented. I'm at a point where I want to use the AWS autoscaler and i'm not sure how.

I see in the docs that I need to supply the access+secret keys, which are associated with an IAM, but nowhere does it say what permissions does this IAM need in order to execute.

Also using the name "AWS Autoscaler" immediately suggests that behind the scene, trains uses the https://docs.aws.amazon.com/autoscaling/ec2/userguide/what-is-amazon-ec2-auto-scaling.html service hence I should grant this service's permissiosn to it, but your message suggest ohterwise, where I would need to assign EC2 specific permissions to it. Since security is always a big issue, I think the documentation should be explicit about which permissions does the IAM need in order to use this feature - and nothing easier than supplying the actual policy's JSON
