Instance Attribute Details

#default_result ⇒ String

The action the Auto Scaling group takes when the lifecycle hook timeout elapses or if an unexpected failure occurs. The default value is ‘ABANDON`.

Valid values: ‘CONTINUE` | `ABANDON`

Returns:

#lifecycle_transition ⇒ String

The lifecycle transition. For Auto Scaling groups, there are two major lifecycle transitions.

• To create a lifecycle hook for scale-out events, specify ‘autoscaling:EC2_INSTANCE_LAUNCHING`.

• To create a lifecycle hook for scale-in events, specify ‘autoscaling:EC2_INSTANCE_TERMINATING`.

Returns:

• (String)

#notification_target_arn ⇒ String

The Amazon Resource Name (ARN) of the notification target that Amazon EC2 Auto Scaling sends notifications to when an instance is in a wait state for the lifecycle hook. You can specify an Amazon SNS topic or an Amazon SQS queue.

Returns:

• (String)

  SENSITIVE = []
  include Aws::Structure
end

#role_arn ⇒ String

The ARN of the IAM role that allows the Auto Scaling group to publish to the specified notification target. For information about creating this role, see [Prepare to add a lifecycle hook to your Auto Scaling group] in the *Amazon EC2 Auto Scaling User Guide*.

Valid only if the notification target is an Amazon SNS topic or an Amazon SQS queue.
