Method: Aws::AutoScaling::Types::RefreshPreferences#auto_rollback

Defined in:

lib/aws-sdk-autoscaling/types.rb

#auto_rollback ⇒ Boolean

(Optional) Indicates whether to roll back the Auto Scaling group to its previous configuration if the instance refresh fails or a CloudWatch alarm threshold is met. The default is ‘false`.

A rollback is not supported in the following situations:

• There is no desired configuration specified for the instance refresh.

• The Auto Scaling group has a launch template that uses an Amazon Web Services Systems Manager parameter instead of an AMI ID for the ‘ImageId` property.

• The Auto Scaling group uses the launch template’s ‘$Latest` or `$Default` version.

For more information, see [Undo changes with a rollback] in the *Amazon EC2 Auto Scaling User Guide*.
