Create a value of UpdateAutoScalingGroup with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

UpdateAutoScalingGroup, updateAutoScalingGroup_availabilityZones - One or more Availability Zones for the group.

UpdateAutoScalingGroup, updateAutoScalingGroup_capacityRebalance - Enables or disables Capacity Rebalancing. For more information, see Use Capacity Rebalancing to handle Amazon EC2 Spot Interruptions in the Amazon EC2 Auto Scaling User Guide.

UpdateAutoScalingGroup, updateAutoScalingGroup_context - Reserved.

UpdateAutoScalingGroup, updateAutoScalingGroup_defaultCooldown - Only needed if you use simple scaling policies.

The amount of time, in seconds, between one scaling activity ending and another one starting due to simple scaling policies. For more information, see Scaling cooldowns for Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide.

UpdateAutoScalingGroup, updateAutoScalingGroup_defaultInstanceWarmup - The amount of time, in seconds, until a newly launched instance can contribute to the Amazon CloudWatch metrics. This delay lets an instance finish initializing before Amazon EC2 Auto Scaling aggregates instance metrics, resulting in more reliable usage data. Set this value equal to the amount of time that it takes for resource consumption to become stable after an instance reaches the InService state. For more information, see Set the default instance warmup for an Auto Scaling group in the Amazon EC2 Auto Scaling User Guide.

To manage your warm-up settings at the group level, we recommend that you set the default instance warmup, /even if its value is set to 0 seconds/. This also optimizes the performance of scaling policies that scale continuously, such as target tracking and step scaling policies.

If you need to remove a value that you previously set, include the property but specify -1 for the value. However, we strongly recommend keeping the default instance warmup enabled by specifying a minimum value of 0.

UpdateAutoScalingGroup, updateAutoScalingGroup_desiredCapacity - 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.

UpdateAutoScalingGroup, updateAutoScalingGroup_desiredCapacityType - The unit of measurement for the value specified for desired capacity. Amazon EC2 Auto Scaling supports DesiredCapacityType for attribute-based instance type selection only. For more information, see Creating an Auto Scaling group using attribute-based instance type selection in the Amazon EC2 Auto Scaling User Guide.

By default, Amazon EC2 Auto Scaling specifies units, which translates into number of instances.

Valid values: units | vcpu | memory-mib

UpdateAutoScalingGroup, updateAutoScalingGroup_healthCheckGracePeriod - 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 and marking it unhealthy due to a failed health check. This is useful if your instances do not immediately pass their health checks after they enter the InService state. For more information, see Set the health check grace period for an Auto Scaling group in the Amazon EC2 Auto Scaling User Guide.

UpdateAutoScalingGroup, updateAutoScalingGroup_healthCheckType - Determines whether any additional health checks are performed on the instances in this group. Amazon EC2 health checks are always on.

The valid values are EC2 (default), ELB, and VPC_LATTICE. The VPC_LATTICE health check type is reserved for use with VPC Lattice, which is in preview release and is subject to change.

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

UpdateAutoScalingGroup, updateAutoScalingGroup_launchTemplate - 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.

UpdateAutoScalingGroup, updateAutoScalingGroup_maxInstanceLifetime - 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.

UpdateAutoScalingGroup, updateAutoScalingGroup_maxSize - 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).

UpdateAutoScalingGroup, updateAutoScalingGroup_minSize - The minimum size of the Auto Scaling group.

UpdateAutoScalingGroup, updateAutoScalingGroup_mixedInstancesPolicy - The mixed instances policy. For more information, see Auto Scaling groups with multiple instance types and purchase options in the Amazon EC2 Auto Scaling User Guide.

UpdateAutoScalingGroup, updateAutoScalingGroup_newInstancesProtectedFromScaleIn - 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 Using instance scale-in protection in the Amazon EC2 Auto Scaling User Guide.

UpdateAutoScalingGroup, updateAutoScalingGroup_placementGroup - The name of an existing placement group into which to launch your instances. For more information, see Placement groups in the Amazon EC2 User Guide for Linux Instances.

A cluster placement group is a logical grouping of instances within a single Availability Zone. You cannot specify multiple Availability Zones and a cluster placement group.

UpdateAutoScalingGroup, updateAutoScalingGroup_serviceLinkedRoleARN - 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.

UpdateAutoScalingGroup, updateAutoScalingGroup_terminationPolicies - 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 Work with Amazon EC2 Auto Scaling termination policies in the Amazon EC2 Auto Scaling User Guide.

Valid values: Default | AllocationStrategy | ClosestToNextInstanceHour | NewestInstance | OldestInstance | OldestLaunchConfiguration | OldestLaunchTemplate | arn:aws:lambda:region:account-id:function:my-function:my-alias

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

UpdateAutoScalingGroup, updateAutoScalingGroup_autoScalingGroupName - The name of the Auto Scaling group.

One or more Availability Zones for the group.

Enables or disables Capacity Rebalancing. For more information, see Use Capacity Rebalancing to handle Amazon EC2 Spot Interruptions in the Amazon EC2 Auto Scaling User Guide.
