Method Detail

lifecycleHookName

public final String lifecycleHookName()

The name of the lifecycle hook.

Returns:

The name of the lifecycle hook.

lifecycleTransition

public final String lifecycleTransition()

The state of the EC2 instance to which you want to attach the lifecycle hook. The valid values are:

• autoscaling:EC2_INSTANCE_LAUNCHING

• autoscaling:EC2_INSTANCE_TERMINATING

Returns:

The state of the EC2 instance to which you want to attach the lifecycle hook. The valid values are:

• autoscaling:EC2_INSTANCE_LAUNCHING

• autoscaling:EC2_INSTANCE_TERMINATING

notificationMetadata

public final String notificationMetadata()

Additional information that you want to include any time Amazon EC2 Auto Scaling sends a message to the notification target.

Returns:

Additional information that you want to include any time Amazon EC2 Auto Scaling sends a message to the notification target.

heartbeatTimeout

public final Integer heartbeatTimeout()

The maximum time, in seconds, that can elapse before the lifecycle hook times out.

If the lifecycle hook times out, Amazon EC2 Auto Scaling performs the action that you specified in the DefaultResult parameter. You can prevent the lifecycle hook from timing out by calling RecordLifecycleActionHeartbeat.

Returns:

The maximum time, in seconds, that can elapse before the lifecycle hook times out.

If the lifecycle hook times out, Amazon EC2 Auto Scaling performs the action that you specified in the DefaultResult parameter. You can prevent the lifecycle hook from timing out by calling RecordLifecycleActionHeartbeat.

defaultResult

public final String defaultResult()

Defines the action the Auto Scaling group should take when the lifecycle hook timeout elapses or if an unexpected failure occurs. The valid values are CONTINUE and ABANDON. The default value is ABANDON.

Returns:

Defines the action the Auto Scaling group should take when the lifecycle hook timeout elapses or if an unexpected failure occurs. The valid values are CONTINUE and ABANDON. The default value is ABANDON.

notificationTargetARN

public final String notificationTargetARN()

The ARN of the target that Amazon EC2 Auto Scaling sends notifications to when an instance is in the transition state for the lifecycle hook. The notification target can be either an SQS queue or an SNS topic.

Returns:

The ARN of the target that Amazon EC2 Auto Scaling sends notifications to when an instance is in the transition state for the lifecycle hook. The notification target can be either an SQS queue or an SNS topic.

roleARN

public final String roleARN()

The ARN of the IAM role that allows the Auto Scaling group to publish to the specified notification target.

Valid only if the notification target is an Amazon SNS topic or an Amazon SQS queue. Required for new lifecycle hooks, but optional when updating existing hooks.

Returns:

The ARN of the IAM role that allows the Auto Scaling group to publish to the specified notification target.

Valid only if the notification target is an Amazon SNS topic or an Amazon SQS queue. Required for new lifecycle hooks, but optional when updating existing hooks.
