Creating autoscaling group on spots (or on standart instances) and add autoscaling policy to group
- terraform-aws-modules/autoscaling/aws
- AS_policys
Automatically uses spot-instances if you set spot_price. Set param spot_price = "" to use standart instances Module uses terraform-aws-autoscaling from Terraform AWS modules, and adds aws_autoscaling_policy for scaling ASG.

| force_delete | Allows deleting the autoscaling group without waiting for all instances in the pool to terminate. You can force an autoscaling group to delete even if it's in the process of scaling a resource. Normally Terraform drains all the instances before deleting the group.
