  .. py:method:: attach_instances(**kwargs)

    

    Attaches one or more EC2 instances to the specified Auto Scaling group.

     

    When you attach instances, Auto Scaling increases the desired capacity of the group by the number of instances being attached. If the number of instances being attached plus the desired capacity of the group exceeds the maximum size of the group, the operation fails.

     

    If there is a Classic Load Balancer attached to your Auto Scaling group, the instances are also registered with the load balancer. If there are target groups attached to your Auto Scaling group, the instances are also registered with the target groups.

     

    For more information, see `Attach EC2 Instances to Your Auto Scaling Group <http://docs.aws.amazon.com/autoscaling/latest/userguide/attach-instance-asg.html>`_ in the *Auto Scaling User Guide* .

  .. py:method:: can_paginate(operation_name)

        
    Check if an operation can be paginated.
    
    :type operation_name: string
    :param operation_name: The operation name.  This is the same name
        as the method name on the client.  For example, if the
        method name is ``create_foo``, and you'd normally invoke the
        operation as ``client.create_foo(**kwargs)``, if the
        ``create_foo`` operation can be paginated, you can use the
        call ``client.get_paginator("create_foo")``.
    
    :return: ``True`` if the operation can be paginated,
        ``False`` otherwise.


  .. py:method:: complete_lifecycle_action(**kwargs)

    

    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 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 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 `Auto Scaling Lifecycle <http://docs.aws.amazon.com/autoscaling/latest/userguide/AutoScalingGroupLifecycle.html>`_ in the *Auto Scaling User Guide* .

      The service to use for the health checks. The valid values are ``EC2`` and ``ELB`` .

       

      By default, health checks use Amazon EC2 instance status checks to determine the health of an instance. For more information, see `Health Checks <http://docs.aws.amazon.com/autoscaling/latest/userguide/healthcheck.html>`_ in the *Auto Scaling User Guide* .

      

    
    :type HealthCheckGracePeriod: integer
    :param HealthCheckGracePeriod: 

      The amount of time, in seconds, that Auto Scaling waits before checking the health status of an EC2 instance that has come into service. During this time, any health check failures for the instance are ignored. The default is 0.

       

      This parameter is required if you are adding an ``ELB`` health check.

For more information, see `Launching Auto Scaling Instances in a VPC <http://docs.aws.amazon.com/autoscaling/latest/userguide/asg-in-vpc.html>`_ in the *Auto Scaling User Guide* .

       

      If you specify this parameter, be sure to specify at least one subnet when you create your group.

       

      Default: If the instance is launched into a default subnet, the default is ``true`` . If the instance is launched into a nondefault subnet, the default is ``false`` . For more information, see `Supported Platforms <http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-supported-platforms.html>`_ in the *Amazon Elastic Compute Cloud User Guide* .

      

    
    :type PlacementTenancy: string
    :param PlacementTenancy: 

      The tenancy of the instance. An instance with a tenancy of ``dedicated`` runs on single-tenant hardware and can only be launched into a VPC.

       

      You must set the value of this parameter to ``dedicated`` if want to launch Dedicated Instances into a shared tenancy VPC (VPC with instance placement tenancy attribute set to ``default`` ).

       

      If you specify this parameter, be sure to specify at least one subnet when you create your group.

    If the group has policies, deleting the group deletes the policies, the underlying alarm actions, and any alarm that no longer has an associated action.

     

    To remove instances from the Auto Scaling group before deleting it, call  DetachInstances with the list of instances and the option to decrement the desired capacity so that Auto Scaling does not launch replacement instances.

     

    To terminate all instances before deleting the Auto Scaling group, call  UpdateAutoScalingGroup and set the minimum size and desired capacity of the Auto Scaling group to zero.

          - *(dict) --* 

            Describes a lifecycle hook, which tells Auto Scaling that you want to perform an action when an instance launches or terminates. When you have a lifecycle hook in place, the Auto Scaling group will either:

             

             
            * Pause the instance after it launches, but before it is put into service 
             
            * Pause the instance as it terminates, but before it is fully terminated 
             

             

            For more information, see `Auto Scaling Lifecycle <http://docs.aws.amazon.com/autoscaling/latest/userguide/AutoScalingGroupLifecycle.html>`_ in the *Auto Scaling User Guide* .

            - **NotificationTargetARN** *(string) --* 

              The ARN of the notification target that Auto Scaling uses to notify you when an instance is in the transition state for the lifecycle hook. This ARN target can be either an SQS queue or an SNS topic. The notification message sent to the target includes the following:

               

               
              * Lifecycle action token 
               
              * User account ID 
               
              * Name of the Auto Scaling group

              * Notification metadata 
               

              
            

            - **RoleARN** *(string) --* 

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

              
            

            - **NotificationMetadata** *(string) --* 

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

              
            

            - **HeartbeatTimeout** *(integer) --* 

              The maximum time, in seconds, that can elapse before the lifecycle hook times out. The default is 3600 seconds (1 hour). When the lifecycle hook times out, Auto Scaling performs the default action. You can prevent the lifecycle hook from timing out by calling  RecordLifecycleActionHeartbeat .

              
            

            - **GlobalTimeout** *(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.

              
            

            - **DefaultResult** *(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 ``CONTINUE`` .

              A set of adjustments that enable you to scale based on the size of the alarm breach.

              
              

              - *(dict) --* 

                Describes an adjustment based on the difference between the value of the aggregated CloudWatch metric and the breach threshold that you've defined for the alarm.

                 

                For the following examples, suppose that you have an alarm with a breach threshold of 50:

                 

                 
                * If you want the adjustment to be triggered when the metric is greater than or equal to 50 and less than 60, specify a lower bound of 0 and an upper bound of 10. 
                 
                * If you want the adjustment to be triggered when the metric is greater than 40 and less than or equal to 50, specify a lower bound of -10 and an upper bound of 0. 
                 

                 

                There are a few rules for the step adjustments for your step policy:

                 

                 
                * The ranges of your step adjustments can't overlap or have a gap. 
                 
                * At most one step adjustment can have a null lower bound. If one step adjustment has a negative lower bound, then there must be a step adjustment with a null lower bound. 
                 
                * At most one step adjustment can have a null upper bound. If one step adjustment has a positive upper bound, then there must be a step adjustment with a null upper bound. 
                 
                * The upper and lower bound can't be null in the same step adjustment. 
                 

                
                

                - **MetricIntervalLowerBound** *(float) --* 

                  The lower bound for the difference between the alarm threshold and the CloudWatch metric. If the metric value is above the breach threshold, the lower bound is inclusive (the metric must be greater than or equal to the threshold plus the lower bound). Otherwise, it is exclusive (the metric must be greater than the threshold plus the lower bound). A null value indicates negative infinity.

                  
                

                - **MetricIntervalUpperBound** *(float) --* 

                  The upper bound for the difference between the alarm threshold and the CloudWatch metric. If the metric value is above the breach threshold, the upper bound is exclusive (the metric must be less than the threshold plus the upper bound). Otherwise, it is inclusive (the metric must be less than or equal to the threshold plus the upper bound). A null value indicates positive infinity.

                   

                  The upper bound must be greater than the lower bound.

                  
                

                - **ScalingAdjustment** *(integer) --* 

                  The amount by which to scale, based on the specified adjustment type. A positive value adds to the current capacity while a negative number removes from the current capacity.

  .. py:method:: describe_tags(**kwargs)

    

    Describes the specified tags.

     

    You can use filters to limit the results. For example, you can query for the tags for a specific Auto Scaling group. You can specify multiple values for a filter. A tag must match at least one of the specified values for it to be included in the results.

     

    You can also specify multiple filters. The result includes information for a particular tag only if it matches all the filters. If there's no match, no special message is returned.

  .. py:method:: detach_instances(**kwargs)

    

    Removes one or more instances from the specified Auto Scaling group.

     

    After the instances are detached, you can manage them independently from the rest of the Auto Scaling group.

     

    If you do not specify the option to decrement the desired capacity, Auto Scaling launches instances to replace the ones that are detached.

     

    If there is a Classic Load Balancer attached to the Auto Scaling group, the instances are deregistered from the load balancer. If there are target groups attached to the Auto Scaling group, the instances are deregistered from the target groups.

  .. py:method:: detach_load_balancers(**kwargs)

    

    Detaches one or more Classic Load Balancers from the specified Auto Scaling group.

     

    Note that this operation detaches only Classic Load Balancers. If you have Application Load Balancers, use  DetachLoadBalancerTargetGroups instead.

     

    When you detach a load balancer, it enters the ``Removing`` state while deregistering the instances in the group. When all instances are deregistered, then you can no longer describe the load balancer using  DescribeLoadBalancers . Note that the instances remain running.

  .. py:method:: get_waiter(waiter_name)

        


  .. py:method:: put_lifecycle_hook(**kwargs)

    

    Creates or updates a lifecycle hook for the specified Auto Scaling Group.

     

    A lifecycle hook tells Auto Scaling that you want to perform an action on an instance that is not actively in service; for example, either when the instance launches or before the instance terminates.

     

    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 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 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 `Auto Scaling Lifecycle Hooks <http://docs.aws.amazon.com/autoscaling/latest/userguide/lifecycle-hooks.html>`_ in the *Auto Scaling User Guide* .

     

    If you exceed your maximum limit of lifecycle hooks, which by default is 50 per Auto Scaling group, the call fails. For information about updating this limit, see `AWS Service Limits <http://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html>`_ in the *Amazon Web Services General Reference* .

    :param LifecycleHookName: **[REQUIRED]** 

      The name of the lifecycle hook.

      

    
    :type AutoScalingGroupName: string
    :param AutoScalingGroupName: **[REQUIRED]** 

      The name of the Auto Scaling group to which you want to assign the lifecycle hook.

      

    
    :type LifecycleTransition: string
    :param LifecycleTransition: 

      The instance state to which you want to attach the lifecycle hook. For a list of lifecycle hook types, see  DescribeLifecycleHookTypes .

       

      This parameter is required for new lifecycle hooks, but optional when updating existing hooks.

      

    
    :type RoleARN: string
    :param RoleARN: 

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

       

      This parameter is required for new lifecycle hooks, but optional when updating existing hooks.

      

    
    :type NotificationTargetARN: string
    :param NotificationTargetARN: 

      The ARN of the notification target that Auto Scaling will use to notify you when an instance is in the transition state for the lifecycle hook. This target can be either an SQS queue or an SNS topic. If you specify an empty string, this overrides the current ARN.

       

      This operation uses the JSON format when sending notifications to an Amazon SQS queue, and an email key/value pair format when sending notifications to an Amazon SNS topic.

       

      When you specify a notification target, Auto Scaling sends it a test message. Test messages contains the following additional key/value pair: ``"Event": "autoscaling:TEST_NOTIFICATION"`` .

      

    
    :type NotificationMetadata: string
    :param NotificationMetadata: 

      Contains additional information that you want to include any time Auto Scaling sends a message to the notification target.

      

    
    :type HeartbeatTimeout: integer
    :param HeartbeatTimeout: 

      The amount of time, in seconds, that can elapse before the lifecycle hook times out. When the lifecycle hook times out, Auto Scaling performs the default action. You can prevent the lifecycle hook from timing out by calling  RecordLifecycleActionHeartbeat . The default is 3600 seconds (1 hour).

      

    
    :type DefaultResult: string
    :param DefaultResult: 

      Defines the action the Auto Scaling group should take when the lifecycle hook timeout elapses or if an unexpected failure occurs. This parameter can be either ``CONTINUE`` or ``ABANDON`` . The default value is ``ABANDON`` .

      This parameter is required if the policy type is ``StepScaling`` and not supported otherwise.

      

    
      - *(dict) --* 

        Describes an adjustment based on the difference between the value of the aggregated CloudWatch metric and the breach threshold that you've defined for the alarm.

         

        For the following examples, suppose that you have an alarm with a breach threshold of 50:

         

         
        * If you want the adjustment to be triggered when the metric is greater than or equal to 50 and less than 60, specify a lower bound of 0 and an upper bound of 10. 
         
        * If you want the adjustment to be triggered when the metric is greater than 40 and less than or equal to 50, specify a lower bound of -10 and an upper bound of 0. 
         

         

        There are a few rules for the step adjustments for your step policy:

         

         
        * The ranges of your step adjustments can't overlap or have a gap. 
         
        * At most one step adjustment can have a null lower bound. If one step adjustment has a negative lower bound, then there must be a step adjustment with a null lower bound. 
         
        * At most one step adjustment can have a null upper bound. If one step adjustment has a positive upper bound, then there must be a step adjustment with a null upper bound. 
         
        * The upper and lower bound can't be null in the same step adjustment. 
         

        

      
        - **MetricIntervalLowerBound** *(float) --* 

          The lower bound for the difference between the alarm threshold and the CloudWatch metric. If the metric value is above the breach threshold, the lower bound is inclusive (the metric must be greater than or equal to the threshold plus the lower bound). Otherwise, it is exclusive (the metric must be greater than the threshold plus the lower bound). A null value indicates negative infinity.

          

        
        - **MetricIntervalUpperBound** *(float) --* 

          The upper bound for the difference between the alarm threshold and the CloudWatch metric. If the metric value is above the breach threshold, the upper bound is exclusive (the metric must be less than the threshold plus the upper bound). Otherwise, it is inclusive (the metric must be less than or equal to the threshold plus the upper bound). A null value indicates positive infinity.

           

          The upper bound must be greater than the lower bound.

          

        
        - **ScalingAdjustment** *(integer) --* **[REQUIRED]** 

          The amount by which to scale, based on the specified adjustment type. A positive value adds to the current capacity while a negative number removes from the current capacity.

          

        
      
  
    :type EstimatedInstanceWarmup: integer
    :param EstimatedInstanceWarmup: 

      The estimated time, in seconds, until a newly launched instance can contribute to the CloudWatch metrics. The default is to use the value specified for the default cooldown period for the group.

       

      This parameter is supported if the policy type is ``StepScaling`` or ``TargetTrackingScaling`` .

      

    
    :type TargetTrackingConfiguration: dict
    :param TargetTrackingConfiguration: 

      The configuration of a target tracking policy.

       

      This parameter is required if the policy type is ``TargetTrackingScaling`` and not supported otherwise.

      

    
      - **PredefinedMetricSpecification** *(dict) --* 

        A predefined metric. You can specify either a predefined metric or a customized metric.

        

      
        - **PredefinedMetricType** *(string) --* **[REQUIRED]** 

          The metric type.

          

        
        - **ResourceLabel** *(string) --* 

          Identifies the resource associated with the metric type. For predefined metric types ``ASGAverageCPUUtilization`` , ``ASGAverageNetworkIn`` and ``ASGAverageNetworkOut`` , the parameter must not be specified as the resource associated with the metric type is the Auto Scaling group. For predefined metric type ``ALBRequestCountPerTarget`` , the parameter must be specified in the format ``app/*load-balancer-name* /*load-balancer-id* /targetgroup/*target-group-name* /*target-group-id* `` , where ``app/*load-balancer-name* /*load-balancer-id* `` is the final portion of the load balancer ARN, and ``targetgroup/*target-group-name* /*target-group-id* `` is the final portion of the target group ARN. The target group must be attached to the Auto Scaling group.

          

        
      
      - **CustomizedMetricSpecification** *(dict) --* 

        A customized metric.

  .. py:method:: record_lifecycle_action_heartbeat(**kwargs)

    

    Records a heartbeat for the lifecycle action associated with the specified token or instance. This extends the timeout by the length of time defined using  PutLifecycleHook .

     

    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 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 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.

  .. py:method:: update_auto_scaling_group(**kwargs)

    

    Updates the configuration for the specified Auto Scaling group.

     

    To update an Auto Scaling group with a launch configuration with ``InstanceMonitoring`` set to ``False`` , you must first disable the collection of group metrics. Otherwise, you will get an error. If you have previously enabled the collection of group metrics, you can disable it using  DisableMetricsCollection .

     

    The new settings are registered upon the completion of this call. Any launch configuration settings take effect on any triggers after this call returns. Scaling activities that are currently in progress aren't affected.

     

    Note the following:

     

     
    * If you specify a new value for ``MinSize`` without specifying a value for ``DesiredCapacity`` , and the new ``MinSize`` is larger than the current size of the group, we implicitly call  SetDesiredCapacity to set the size of the group to the new value of ``MinSize`` . 
     
    * If you specify a new value for ``MaxSize`` without specifying a value for ``DesiredCapacity`` , and the new ``MaxSize`` is smaller than the current size of the group, we implicitly call  SetDesiredCapacity to set the size of the group to the new value of ``MaxSize`` . 
     
    * All other optional parameters are left unchanged if not specified.

Otherwise, the error is ``ValidationError`` .

              
            

            - **ScalingAdjustment** *(integer) --* 

              The amount by which to scale, based on the specified adjustment type. A positive value adds to the current capacity while a negative number removes from the current capacity.

              
            

            - **Cooldown** *(integer) --* 

              The amount of time, in seconds, after a scaling activity completes before any further trigger-related scaling activities can start.

              
            

            - **StepAdjustments** *(list) --* 

              A set of adjustments that enable you to scale based on the size of the alarm breach.

              
              

              - *(dict) --* 

                Describes an adjustment based on the difference between the value of the aggregated CloudWatch metric and the breach threshold that you've defined for the alarm.

                 

                For the following examples, suppose that you have an alarm with a breach threshold of 50:

                 

                 
                * If you want the adjustment to be triggered when the metric is greater than or equal to 50 and less than 60, specify a lower bound of 0 and an upper bound of 10. 
                 
                * If you want the adjustment to be triggered when the metric is greater than 40 and less than or equal to 50, specify a lower bound of -10 and an upper bound of 0. 
                 

                 

                There are a few rules for the step adjustments for your step policy:

                 

                 
                * The ranges of your step adjustments can't overlap or have a gap. 
                 
                * At most one step adjustment can have a null lower bound. If one step adjustment has a negative lower bound, then there must be a step adjustment with a null lower bound. 
                 
                * At most one step adjustment can have a null upper bound. If one step adjustment has a positive upper bound, then there must be a step adjustment with a null upper bound. 
                 
                * The upper and lower bound can't be null in the same step adjustment. 
                 

                
                

                - **MetricIntervalLowerBound** *(float) --* 

                  The lower bound for the difference between the alarm threshold and the CloudWatch metric. If the metric value is above the breach threshold, the lower bound is inclusive (the metric must be greater than or equal to the threshold plus the lower bound). Otherwise, it is exclusive (the metric must be greater than the threshold plus the lower bound). A null value indicates negative infinity.

                  
                

                - **MetricIntervalUpperBound** *(float) --* 

                  The upper bound for the difference between the alarm threshold and the CloudWatch metric. If the metric value is above the breach threshold, the upper bound is exclusive (the metric must be less than the threshold plus the upper bound). Otherwise, it is inclusive (the metric must be less than or equal to the threshold plus the upper bound). A null value indicates positive infinity.

                   

                  The upper bound must be greater than the lower bound.

                  
                

                - **ScalingAdjustment** *(integer) --*
