Auto Scaling:DeleteScalingGroup

Last Updated:Jun 06, 2024

Deletes a scaling group. If you want to enable policy-based automatic addition or removal of instances of a specific type to meet evolving business requirements, you can create scaling groups to manage your computing power with ease. The computing power refers to the instances that provide the computing capability. If you no longer require a scaling group, you can call the DeleteScalingGroup operation to delete it to free up the scaling group quota.

Operation description

Before you call the DeleteScalingGroup operation, take note of the following items:

  • If you delete a scaling group, the scaling configurations, scaling rules, scaling activities, and scaling requests related to the scaling group are also deleted.

  • If you delete a scaling group, the scheduled tasks and event-triggered tasks of the scaling group are not deleted. The Server Load Balancer (SLB) instances and ApsaraDB RDS instances that are attached to the scaling group are also not deleted.

  • If the scaling group that you want to delete contains ECS instances or elastic container instances that are in the In Service state, Auto Scaling stops the instances and then removes all manually added instances from the scaling group or releases all automatically created instances in the scaling group before the scaling group is deleted.

    **

    Note Before you delete a scaling group, make sure that the Deletion Protection feature is disabled. If you have enabled the Deletion Protection feature for a scaling group, disable the feature on the Modify Scaling Group page before you delete the scaling group.

  • If you do not disable the Deletion Protection feature for a scaling group, you cannot delete the scaling group by using the Auto Scaling console or calling this operation. The Deletion Protection feature is an effective measure to safeguard scaling groups against unintended deletion.

  • Prior to deleting a scaling group, make sure that your ECS instances within the scaling group are safeguarded against unintended release. Even if you have already enabled the Release Protection feature for the ECS instances, you must manually put these ECS instances into the Protected state. Doing so guarantees that the ECS instances will not be forcibly released during the deletion process of the scaling group, providing an extra layer of security.

    **

    Note Before you delete a scaling group, we recommend that you enable the Deletion Protection feature for ECS instances that you want to retain. This action guarantees that the ECS instances are not forcibly released after you delete the scaling group. For more information, see SetInstancesProtection .

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

  • Operation: the value that you can use in the Action element to specify the operation on a resource.
  • Access level: the access level of each operation. The levels are read, write, and list.
  • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
    • The required resource types are displayed in bold characters.
    • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
  • Condition Key: the condition key that is defined by the cloud service.
  • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Request parameters

ParameterTypeRequiredDescriptionExample
ScalingGroupIdstringYes

The ID of the scaling group.

asg-bp18p2yfxow2dloq****
ForceDeletebooleanNo

Specifies whether to enforce the deletion of the scaling group, including the removal of the current ECS instances or elastic container instances from the scaling group and their subsequent release, even if the scaling group is actively undergoing scaling activities. Valid values:

  • true: enforces the deletion of the scaling group. In this case, the scaling group first enters the Disabled state, ceasing acceptance of new scaling requests. Auto Scaling awaits the conclusion of all ongoing scaling activities in the scaling group before it automatically removes the current ECS instances or elastic container instances from the scaling group and enforces the deletion operation. Note that manually added instances are merely removed from the scaling group, whereas auto-provisioned instances are removed and deleted.

  • false: does not enforce the deletion of the scaling group. The scaling group will be disabled and then deleted once all the following requirements are satisfied:

    • The scaling group has no ongoing scaling activities.
    • The scaling group contains no ECS instances or elastic container instances (Total Capacity=0).

Default value: false.

false
RegionIdstringNo

The region ID of the scaling group.
