Creates a scaling group

Description

The example uses the following parameters:

• MinSize: the minimum number of Elastic Compute Service (ECS) instances in the scaling group. If the current count drops below this value, Auto Scaling adds ECS instances to reach the minimum.

• MaxSize: the maximum number of ECS instances in the scaling group. If the current count exceeds this value, Auto Scaling removes excess ECS instances to stay within the limit.

• LoadBalancerIds: the IDs of the Classic Load Balancer (CLB, formerly known as SLB) instances to associate with the scaling group. Accepts a JSON array of multiple CLB instance IDs, separated by commas (,).

• DBInstanceIds: the IDs of the ApsaraDB RDS instances to associate with the scaling group. Accepts a JSON array of multiple ApsaraDB RDS instance IDs, separated by commas (,).

For a full list of parameters, see CreateScalingGroup.
