short_description: Create or delete AWS Autoscaling Launch Configurations

|
|
description:
|
|
- Can create or delete AWS Autoscaling Configurations
|
|
- Works with the ec2_asg module to manage Autoscaling Groups
|
|
|
|
notes:
|
|
- Amazon ASG Autoscaling Launch Configurations are immutable once created, so modifying the configuration after it is changed will not modify the
|
|
launch configuration on AWS. You must create a new config and assign it to the ASG instead.
|
|
- encrypted volumes are supported on versions >= 2.4
