|---|---|---|---|---|---|
| asg_names | list | null | No | ASG Names | One or many ASG names as a JSON encoded list |
| tags | list | null | No | ASG Tags | List of AWS tags for to identify ASG by tags instead of by names |

One of:
- asg_names: a list of one or more asg names
- tags: a list of key/value pair to identify asg(s) by
One of:
- instance_count: integer value of number of instances to detach
- instance_percent: 1-100, percent of instances to detach
