For cost reasons, our ASG's in the QA environment run with desired/min/max capacity set to "1". That's not the case for Production but since we use the same code for QA and Prod deployment (minus a few variables of course) this is causing problems with the QA automation jobs.

On the first run, the "ec2_asg" module creates the group properly, with the correct desired/min/max settings.
But when we run the job a second time to update the same ASG, it changes desired/min/max to "2" in AWS. We don't want that. We just want it to rotate out that one instance in the group. Is there a way to achieve that?
