InstanceId Property
AmazonAmazon.AutoScaling.ModelCreateAutoScalingGroupRequestInstanceId Did this page help you?   Yes   No    Tell us about it...
The ID of the Amazon EC2 instance you want to use to create the Auto Scaling group. Use this attribute if you want to create an Auto Scaling group using an EC2 instance instead of a launch configuration. When you use an instance to create an Auto Scaling group, a new launch configuration is first created and then associated with the Auto Scaling group. The new launch configuration derives all its attributes from the instance that is used to create the Auto Scaling group, with the exception of BlockDeviceMapping. For more information, see Create an Auto Scaling Group Using EC2 Instance in the Auto Scaling Developer Guide.
