@!attribute [rw] auto_scaling_group_name
The name of the Auto Scaling group. @return [String]
@!attribute [rw] launch_configuration_name
The name of the launch configuration. If you specify `LaunchConfigurationName` in your update request, you can't specify `LaunchTemplate` or `MixedInstancesPolicy`. @return [String]
@!attribute [rw] launch_template
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`. @return [Types::LaunchTemplateSpecification]
@!attribute [rw] mixed_instances_policy
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][1] in the *Amazon EC2 Auto Scaling User Guide*. [1]: https://docs.aws.amazon.com/autoscaling/ec2/userguide/asg-purchase-options.html @return [Types::MixedInstancesPolicy]
@!attribute [rw] min_size
The minimum size of the Auto Scaling group. @return [Integer]
@!attribute [rw] max_size
The maximum size of the Auto Scaling group. <note markdown="1"> 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). </note> @return [Integer]
@!attribute [rw] desired_capacity
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. @return [Integer]
@!attribute [rw] default_cooldown
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][1] in the *Amazon EC2 Auto Scaling User Guide*. [1]: https://docs.aws.amazon.com/autoscaling/ec2/userguide/Cooldown.html @return [Integer]
@!attribute [rw] availability_zones
One or more Availability Zones for the group. @return [Array<String>]
@!attribute [rw] health_check_type
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. @return [String]
@!attribute [rw] health_check_grace_period
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][1] in the *Amazon EC2 Auto Scaling User Guide*. Conditional: Required if you are adding an `ELB` health check. [1]: https://docs.aws.amazon.com/autoscaling/ec2/userguide/healthcheck.html#health-check-grace-period @return [Integer]
@!attribute [rw] placement_group
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][1] in the *Amazon EC2 User Guide for Linux Instances*. [1]: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.html @return [String]
@!attribute [rw] vpc_zone_identifier
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. @return [String]
@!attribute [rw] termination_policies
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][1] in the *Amazon EC2 Auto Scaling User Guide*. [1]: https://docs.aws.amazon.com/autoscaling/ec2/userguide/as-instance-termination.html @return [Array<String>]
@!attribute [rw] new_instances_protected_from_scale_in
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][1] in the *Amazon EC2 Auto Scaling User Guide*. [1]: https://docs.aws.amazon.com/autoscaling/ec2/userguide/as-instance-termination.html#instance-protection @return [Boolean]
@!attribute [rw] service_linked_role_arn
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][1] in the *Amazon EC2 Auto Scaling User Guide*. [1]: https://docs.aws.amazon.com/autoscaling/ec2/userguide/autoscaling-service-linked-role.html @return [String]
@!attribute [rw] max_instance_lifetime
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][1] in the *Amazon EC2 Auto Scaling User Guide*. [1]: https://docs.aws.amazon.com/autoscaling/ec2/userguide/asg-max-instance-lifetime.html @return [Integer]
@!attribute [rw] capacity_rebalance
Enables or disables Capacity Rebalancing. For more information, see [Amazon EC2 Auto Scaling Capacity Rebalancing][1] in the *Amazon EC2 Auto Scaling User Guide*. [1]: https://docs.aws.amazon.com/autoscaling/ec2/userguide/capacity-rebalance.html @return [Boolean]
@!attribute [rw] context
Reserved. @return [String]
