Amazonka.AutoScaling.UpdateAutoScalingGroup

Description

__We strongly recommend that all Auto Scaling groups use launch templates to ensure full functionality for Amazon EC2 Auto Scaling and Amazon EC2.__

Updates the configuration for the specified Auto Scaling group.

To update an Auto Scaling group, specify the name of the group and the parameter that you want to change. Any parameters that you don't specify are not changed by this update request. The new settings take effect on any scaling activities after this call returns.

If you associate a new launch configuration or template with an Auto Scaling group, all new instances will get the updated configuration. Existing instances continue to run with the configuration that they were originally launched with. When you update a group to specify a mixed instances policy instead of a launch configuration or template, existing instances may be replaced to match the new purchasing options that you specified in the policy. For example, if the group currently has 100% On-Demand capacity and the policy specifies 50% Spot capacity, this means that half of your instances will be gradually terminated and relaunched as Spot Instances. When replacing instances, Amazon EC2 Auto Scaling launches new instances before terminating the old ones, so that updating your group does not compromise the performance or availability of your application.

Note the following about changing DesiredCapacity, MaxSize, or MinSize:

  • If a scale-in activity occurs as a result of a new DesiredCapacity value that is lower than the current size of the group, the Auto Scaling group uses its termination policy to determine which instances to terminate.
  • 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, this sets the group's DesiredCapacity to the new MinSize value.
  • 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, this sets the group's DesiredCapacity to the new MaxSize value.

To see which parameters have been set, call the DescribeAutoScalingGroups API. To view the scaling policies for an Auto Scaling group, call the DescribePolicies API. If the group has scaling policies, you can update them by calling the PutScalingPolicy API.

Constructors

UpdateAutoScalingGroup' 

Fields

  • context :: Maybe Text

    Reserved.

  • terminationPolicies :: Maybe [Text]

    A policy or a list of policies that are used to select the instances to terminate. The policies are executed in the order that you list them. For more information, see Controlling which Auto Scaling instances terminate during scale in in the Amazon EC2 Auto Scaling User Guide.

  • healthCheckGracePeriod :: Maybe Int

    The amount of time, in seconds, that Amazon EC2 Auto Scaling waits before checking the health status of an EC2 instance that has come into service. The default value is 0. For more information, see Health check grace period in the Amazon EC2 Auto Scaling User Guide.

    Conditional: Required if you are adding an ELB health check.

  • serviceLinkedRoleARN :: Maybe Text

    The Amazon Resource Name (ARN) of the service-linked role that the Auto Scaling group uses to call other Amazon Web Services on your behalf. For more information, see Service-linked roles in the Amazon EC2 Auto Scaling User Guide.

  • newInstancesProtectedFromScaleIn' :: Maybe Bool

    Indicates whether newly launched instances are protected from termination by Amazon EC2 Auto Scaling when scaling in. For more information about preventing instances from terminating on scale in, see Instance scale-in protection in the Amazon EC2 Auto Scaling User Guide.

  • vPCZoneIdentifier :: Maybe Text

    A comma-separated list of subnet IDs for a virtual private cloud (VPC). If you specify VPCZoneIdentifier with AvailabilityZones, the subnets that you specify for this parameter must reside in those Availability Zones.

  • maxInstanceLifetime :: Maybe Int

    The maximum amount of time, in seconds, that an instance can be in service. The default is null. If specified, the value must be either 0 or a number equal to or greater than 86,400 seconds (1 day). To clear a previously set value, specify a new value of 0. For more information, see Replacing Auto Scaling instances based on maximum instance lifetime in the Amazon EC2 Auto Scaling User Guide.

  • defaultCooldown :: Maybe Int

    The amount of time, in seconds, after a scaling activity completes before another scaling activity can start. The default value is 300. This setting applies when using simple scaling policies, but not when using other scaling policies or scheduled scaling. For more information, see Scaling cooldowns for Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide.

  • maxSize :: Maybe Int

    The maximum size of the Auto Scaling group.

    With a mixed instances policy that uses instance weighting, Amazon EC2 Auto Scaling may need to go above MaxSize to meet your capacity requirements. In this event, Amazon EC2 Auto Scaling will never go above MaxSize by more than your largest instance weight (weights that define how many units each instance contributes to the desired capacity of the group).

  • availabilityZones :: Maybe [Text]

    One or more Availability Zones for the group.

  • desiredCapacity :: Maybe Int

    The desired capacity is the initial capacity of the Auto Scaling group after this operation completes and the capacity it attempts to maintain. This number must be greater than or equal to the minimum size of the group and less than or equal to the maximum size of the group.

  • mixedInstancesPolicy :: Maybe MixedInstancesPolicy

    An embedded object that specifies a mixed instances policy. When you make changes to an existing policy, all optional properties are left unchanged if not specified. For more information, see Auto Scaling groups with multiple instance types and purchase options in the Amazon EC2 Auto Scaling User Guide.

  • minSize :: Maybe Int

    The minimum size of the Auto Scaling group.

  • launchConfigurationName :: Maybe Text

    The name of the launch configuration. If you specify LaunchConfigurationName in your update request, you can't specify LaunchTemplate or MixedInstancesPolicy.

  • healthCheckType :: Maybe Text

    The service to use for the health checks. The valid values are EC2 and ELB. If you configure an Auto Scaling group to use ELB health checks, it considers the instance unhealthy if it fails either the EC2 status checks or the load balancer health checks.

  • launchTemplate :: Maybe LaunchTemplateSpecification

    The launch template and version to use to specify the updates. If you specify LaunchTemplate in your update request, you can't specify LaunchConfigurationName or MixedInstancesPolicy.

  • capacityRebalance :: Maybe Bool

    Enables or disables Capacity Rebalancing. For more information, see Amazon EC2 Auto Scaling Capacity Rebalancing in the Amazon EC2 Auto Scaling User Guide.

  • placementGroup :: Maybe Text

    The name of an existing placement group into which to launch your instances, if any. A placement group is a logical grouping of instances within a single Availability Zone. You cannot specify multiple Availability Zones and a placement group. For more information, see Placement Groups in the Amazon EC2 User Guide for Linux Instances.

  • autoScalingGroupName :: Text

    The name of the Auto Scaling group.
