Hi,

I have an autoscaling group which normally has a desired capacity of 0.  It is used only for database restorals.  When we want to do a restore, we set the "DesiredCapacity" to 1. This causes a larger, more powerful, image to start. Once the restore completes, we set the DesiredCapacity back to 0 and the image is taken down. Setting this via the aws cli works fine and has for some time.

So far, I can't get the desired capacity to change the ansible "ec2_scaling_policy" module. Here is one definition I tried 

- name: Prep for autoscaling
  hosts: localhost
  sudo: no
  tasks:
    - name: Set autoscaling policy
      register: adjust
      ec2_scaling_policy:
        region: us-east-1
        asg_name: "{{rethinkdb_restoral_group}}"
        name: "upscale"
        state: present
        adjustment_type: "DesiredCapacity"
        scaling_adjustment: 1
        min_adjustment_step: 1

    - name: Show status
      debug: var=adjust

Output of debug statement above:

TASK [Show status] *************************************************************

ok: [localhost] => {

    "adjust": {

        "adjustment_type": "ChangeInCapacity",

        "arn": "<yadda-yadda>",

        "changed": false,

        "cooldown": null,

        "min_adjustment_step": 1,

        "name": "upscale",

        "scaling_adjustment": 1

    }

}

 The capacity did not change, and the new image did not come up. What am I missing? 

Thanks,
