AWSAutoScalingUpdateAutoScalingGroupType

Objective-C

@interface AWSAutoScalingUpdateAutoScalingGroupType

Swift

class AWSAutoScalingUpdateAutoScalingGroupType
  • The name of the Auto Scaling group.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable autoScalingGroupName;

    Swift

    var autoScalingGroupName: String? { get set }
  • One or more Availability Zones for the group.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSArray<NSString *> *_Nullable availabilityZones;

    Swift

    var availabilityZones: [String]? { get set }
  • 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

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable defaultCooldown;

    Swift

    var defaultCooldown: NSNumber? { get set }
  • 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

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable desiredCapacity;

    Swift

    var desiredCapacity: NSNumber? { get set }
  • 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

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable healthCheckGracePeriod;

    Swift

    var healthCheckGracePeriod: NSNumber? { get set }
  • 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

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable healthCheckType;

    Swift

    var healthCheckType: String? { get set }
  • The name of the launch configuration. If you specify LaunchConfigurationName in your update request, you can’t specify LaunchTemplate or MixedInstancesPolicy.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable launchConfigurationName;

    Swift

    var launchConfigurationName: String? { get set }
  • 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

    Objective-C

    @property (nonatomic, strong) AWSAutoScalingLaunchTemplateSpecification *_Nullable launchTemplate;

    Swift

    var launchTemplate: AWSAutoScalingLaunchTemplateSpecification? { get set }
  • 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

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable maxInstanceLifetime;

    Swift

    var maxInstanceLifetime: NSNumber? { get set }
  • 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

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable maxSize;

    Swift

    var maxSize: NSNumber? { get set }
  • The minimum size of the Auto Scaling group.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable minSize;

    Swift

    var minSize: NSNumber? { get set }
  • 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

    Objective-C

    @property (nonatomic, strong) AWSAutoScalingMixedInstancesPolicy *_Nullable mixedInstancesPolicy;

    Swift

    var mixedInstancesPolicy: AWSAutoScalingMixedInstancesPolicy? { get set }
  • 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

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable latestInstancesProtectedFromScaleIn;

    Swift

    var latestInstancesProtectedFromScaleIn: NSNumber? { get set }
  • 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

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable placementGroup;

    Swift

    var placementGroup: String? { get set }
  • 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

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable serviceLinkedRoleARN;

    Swift

    var serviceLinkedRoleARN: String? { get set }
  • 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

    Objective-C

    @property (nonatomic, strong) NSArray<NSString *> *_Nullable terminationPolicies;

    Swift

    var terminationPolicies: [String]? { get set }
  • 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

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable VPCZoneIdentifier;

    Swift

    var vpcZoneIdentifier: String? { get set }
