Container for the parameters to the CompleteLifecycleAction operation. Completes the lifecycle action for the specified token or instance with the specified result.

This step is a part of the procedure for adding a lifecycle hook to an Auto Scaling group:

  1. (Optional) Create a Lambda function and a rule that allows CloudWatch Events to invoke your Lambda function when Amazon EC2 Auto Scaling launches or terminates instances.

  2. (Optional) Create a notification target and an IAM role. The target can be either an Amazon SQS queue or an Amazon SNS topic. The role allows Amazon EC2 Auto Scaling to publish lifecycle notifications to the target.

  3. Create the lifecycle hook. Specify whether the hook is used when the instances launch or terminate.

  4. If you need more time, record the lifecycle action heartbeat to keep the instance in a pending state.

  5. If you finish before the timeout period ends, complete the lifecycle action.

For more information, see Amazon EC2 Auto Scaling Lifecycle Hooks in the Amazon EC2 Auto Scaling User Guide.

public class CompleteLifecycleActionRequest : AmazonAutoScalingRequest

The CompleteLifecycleActionRequest type exposes the following members



Public Property AutoScalingGroupName System.String

Gets and sets the property AutoScalingGroupName.

The name of the Auto Scaling group.

Public Property InstanceId System.String

Gets and sets the property InstanceId.

The ID of the instance.

Public Property LifecycleActionResult System.String

Gets and sets the property LifecycleActionResult.

The action for the group to take. This parameter can be either CONTINUE or ABANDON.

Public Property LifecycleActionToken System.String

Gets and sets the property LifecycleActionToken.

A universally unique identifier (UUID) that identifies a specific lifecycle action associated with an instance. Amazon EC2 Auto Scaling sends this token to the notification target you specified when you created the lifecycle hook.

Public Property LifecycleHookName System.String

The name of the lifecycle hook.


This example notifies Auto Scaling that the specified lifecycle action is complete so that it can finish launching or terminating the instance.

To complete the lifecycle action

var response = client.CompleteLifecycleAction(new CompleteLifecycleActionRequest 
    AutoScalingGroupName = "my-auto-scaling-group",
    LifecycleActionResult = "CONTINUE",
    LifecycleActionToken = "bcd2f1b8-9a78-44d3-8a7a-4dd07d7cf635",
    LifecycleHookName = "my-lifecycle-hook"
