Overview

Note:

When making an API call, you may pass LifecycleHookSpecification data as a hash:

{
  lifecycle_hook_name: "AsciiStringMaxLen255", # required
  lifecycle_transition: "LifecycleTransition", # required
  notification_metadata: "XmlStringMaxLen1023",
  heartbeat_timeout: 1,
  default_result: "LifecycleActionResult",
  notification_target_arn: "NotificationTargetResourceName",
  role_arn: "ResourceName",
}

Describes a lifecycle hook, which tells Amazon EC2 Auto Scaling that you want to perform an action whenever it launches instances or whenever it terminates instances.

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

• #lifecycle_hook_name ⇒ String

  The name of the lifecycle hook.

• #lifecycle_transition ⇒ String

  The state of the EC2 instance to which you want to attach the lifecycle hook.

• #notification_metadata ⇒ String

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

• #notification_target_arn ⇒ String

  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.

• #role_arn ⇒ String

Instance Attribute Details

#default_result ⇒ String

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`.

Returns:

• (String)

# File 'lib/aws-sdk-autoscaling/types.rb', line 3087

class LifecycleHookSpecification < Struct.new(
  :lifecycle_hook_name,
  :lifecycle_transition,
  :notification_metadata,
  :heartbeat_timeout,
  :default_result,
  :notification_target_arn,
  :role_arn)
  include Aws::Structure
end

#heartbeat_timeout ⇒ Integer

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 default action. You can prevent the lifecycle hook from timing out by calling RecordLifecycleActionHeartbeat.

Returns:

• (Integer)

  :default_result,
  :notification_target_arn,
  :role_arn)
  include Aws::Structure
end

#lifecycle_hook_name ⇒ String

The name of the lifecycle hook.

Returns:

• (String)

# File 'lib/aws-sdk-autoscaling/types.rb', line 3087

class LifecycleHookSpecification < Struct.new(
  :lifecycle_hook_name,

  :default_result,
  :notification_target_arn,
  :role_arn)
  include Aws::Structure
end

#lifecycle_transition ⇒ String

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

• autoscaling:EC2_INSTANCE_LAUNCHING

• autoscaling:EC2_INSTANCE_TERMINATING

Returns:

• (String)

# File 'lib/aws-sdk-autoscaling/types.rb', line 3087

class LifecycleHookSpecification < Struct.new(
  :lifecycle_hook_name,
  :lifecycle_transition,
  :notification_metadata,

  include Aws::Structure
end

#notification_metadata ⇒ String

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

Returns:

• (String)

  :role_arn)
  include Aws::Structure
end

#notification_target_arn ⇒ String

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:

• (String)

# File 'lib/aws-sdk-autoscaling/types.rb', line 3087
