UpdateAutoScalingGroupType

public struct UpdateAutoScalingGroupType : AWSShape

Undocumented

  • Declaration

    Swift

    public static var _members: [AWSShapeMember]

  • The name of the Auto Scaling group.

    Declaration

    Swift

    public let autoScalingGroupName: String

  • One or more Availability Zones for the group.

    Declaration

    Swift

    public let availabilityZones: [String]?

  • 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.

    Declaration

    Swift

    public let defaultCooldown: 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.

    Declaration

    Swift

    public let desiredCapacity: 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. Required if you are adding an ELB health check.

    Declaration

    Swift

    public let healthCheckGracePeriod: Int?

  • 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.

    Declaration

    Swift

    public let healthCheckType: String?

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

    Declaration

    Swift

    public let launchConfigurationName: String?

  • 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. For more information, see LaunchTemplateSpecification in the Amazon EC2 Auto Scaling API Reference.

    Declaration

    Swift

    public let launchTemplate: LaunchTemplateSpecification?

  • The maximum amount of time, in seconds, that an instance can be in service. The default is null. This parameter is optional, but if you specify a value for it, you must specify a value of at least 604,800 seconds (7 days). 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. Valid Range: Minimum value of 0.

    Declaration

    Swift

    public let maxInstanceLifetime: 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).

    Declaration

    Swift

    public let maxSize: Int?

  • The minimum size of the Auto Scaling group.

    Declaration

    Swift

    public let minSize: Int?

  • An embedded object that specifies a mixed instances policy. In your call to UpdateAutoScalingGroup, you can make changes to the policy that is specified. All optional parameters are left unchanged if not specified. For more information, see MixedInstancesPolicy in the Amazon EC2 Auto Scaling API Reference and Auto Scaling Groups with Multiple Instance Types and Purchase Options in the Amazon EC2 Auto Scaling User Guide.

    Declaration

    Swift

    public let mixedInstancesPolicy: MixedInstancesPolicy?

  • 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 Protection in the Amazon EC2 Auto Scaling User Guide.

    Declaration

    Swift

    public let newInstancesProtectedFromScaleIn: Bool?

  • The name of the 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.

    Declaration

    Swift

    public let placementGroup: String?

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

    Declaration

    Swift

    public let serviceLinkedRoleARN: String?

  • A standalone termination policy or a list of termination policies used to select the instance to terminate. The policies are executed in the order that they are listed. For more information, see Controlling Which Instances Auto Scaling Terminates During Scale In in the Amazon EC2 Auto Scaling User Guide.

    Declaration

    Swift

    public let terminationPolicies: [String]?

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

    Declaration

    Swift

    public let vPCZoneIdentifier: String?

  • Undocumented

    Declaration

    Swift

    public init(autoScalingGroupName: String, availabilityZones: [String]? = nil, defaultCooldown: Int? = nil, desiredCapacity: Int? = nil, healthCheckGracePeriod: Int? = nil, healthCheckType: String? = nil, launchConfigurationName: String? = nil, launchTemplate: LaunchTemplateSpecification? = nil, maxInstanceLifetime: Int? = nil, maxSize: Int? = nil, minSize: Int? = nil, mixedInstancesPolicy: MixedInstancesPolicy? = nil, newInstancesProtectedFromScaleIn: Bool? = nil, placementGroup: String? = nil, serviceLinkedRoleARN: String? = nil, terminationPolicies: [String]? = nil, vPCZoneIdentifier: String? = nil)
