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: "XmlStringMaxLen255",
}

Describes information used to specify a lifecycle hook for an Auto Scaling group.

For more information, see Amazon EC2 Auto Scaling lifecycle hooks in the Amazon EC2 Auto Scaling User Guide.

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

• #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

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

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. The default value is ABANDON.

Returns:

• (String)

# File 'gems/aws-sdk-autoscaling/lib/aws-sdk-autoscaling/types.rb', line 5221

class LifecycleHookSpecification < Struct.new(
  :lifecycle_hook_name,
  :lifecycle_transition,
  :notification_metadata,
  :heartbeat_timeout,
  :default_result,
  :notification_target_arn,
  :role_arn)
  SENSITIVE = []
  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 action that you specified in the DefaultResult parameter. You can prevent the lifecycle hook from timing out by calling RecordLifecycleActionHeartbeat.

Returns:

• (Integer)

#lifecycle_hook_name ⇒ String

The name of the lifecycle hook.

Returns:

  SENSITIVE = []
  include Aws::Structure
end

#lifecycle_transition ⇒ String

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:

• (String)

  :role_arn)
  SENSITIVE = []
  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 'gems/aws-sdk-autoscaling/lib/aws-sdk-autoscaling/types.rb', line 5221

class LifecycleHookSpecification < Struct.new(

  :role_arn)
  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.

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:

• (String)

# File 'gems/aws-sdk-autoscaling/lib/aws-sdk-autoscaling/types.rb', line 5221
