Overview

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

  Defines the action the Auto Scaling group should take when the lifecycle hook timeout elapses or if an unexpected failure occurs.

• #global_timeout ⇒ Integer

  The maximum time, in seconds, that an instance can remain in a Pending:Wait or Terminating:Wait state.

• #heartbeat_timeout ⇒ Integer

  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

• #notification_metadata ⇒ String

  Additional information that is included 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

#auto_scaling_group_name ⇒ String

The name of the Auto Scaling group for the lifecycle hook.

Returns:

• (String)

# File 'gems/aws-sdk-autoscaling/lib/aws-sdk-autoscaling/types.rb', line 3314

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

#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 possible values are CONTINUE and ABANDON.

Returns:

• (String)

# File 'gems/aws-sdk-autoscaling/lib/aws-sdk-autoscaling/types.rb', line 3314

class LifecycleHook < Struct.new(
  :lifecycle_hook_name,
  :auto_scaling_group_name,

  :notification_target_arn,
  :role_arn,
  :notification_metadata,
  :heartbeat_timeout,
  :global_timeout,
  :default_result)
  include Aws::Structure
end

#global_timeout ⇒ Integer

The maximum time, in seconds, that an instance can remain in a Pending:Wait or Terminating:Wait state. The maximum is 172800 seconds (48 hours) or 100 times HeartbeatTimeout, whichever is smaller.

Returns:

• (Integer)
