Scaling
Provides a ESS scaling group resource which is a collection of ECS instances with the same application scenarios. It defines the maximum and minimum numbers of ECS instances in the group, and their associated Server Load Balancer instances, RDS instances, and other attributes.
NOTE: You can launch an ESS scaling group for a VPC network via specifying parameter
vswitch_ids. For information about ess scaling rule, see CreateScalingGroup. NOTE: Available since v1.39.0.

}Module Support
You can use to the existing autoscaling module to create a scaling group, configuration and lifecycle hook one-click.
Import
ESS scaling group can be imported using the id, e.g.
$ pulumi import alicloud:ess/scalingGroup:ScalingGroup example asg-abc123456Properties
Instance launch template ID, scaling group obtains launch configuration from instance launch template, see Launch Template. Creating scaling group from launch template enable group automatically.
