complete-lifecycle-action¶

Description¶

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:

(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.
(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.
Create the lifecycle hook. Specify whether the hook is used when the instances launch or terminate.
If you need more time, record the lifecycle action heartbeat to keep the instance in a pending state.
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 .

Synopsis¶

  complete-lifecycle-action
--lifecycle-hook-name <value>
--auto-scaling-group-name <value>
[--lifecycle-action-token <value>]
--lifecycle-action-result <value>
[--instance-id <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options¶

--lifecycle-hook-name (string)

The name of the lifecycle hook.

--auto-scaling-group-name (string)

The name of the Auto Scaling group.

--lifecycle-action-token (string)

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.

--lifecycle-action-result (string)

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

--instance-id (string)

The ID of the instance.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To complete the lifecycle action

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

aws autoscaling complete-lifecycle-action --lifecycle-hook-name my-lifecycle-hook --auto-scaling-group-name my-auto-scaling-group --lifecycle-action-result CONTINUE --lifecycle-action-token bcd2f1b8-9a78-44d3-8a7a-4dd07d7cf635

Output¶
