AWSAutoScalingCreateLaunchConfigurationType

Objective-C

@interface AWSAutoScalingCreateLaunchConfigurationType

Swift

class AWSAutoScalingCreateLaunchConfigurationType

  • Specifies whether to assign a public IPv4 address to the group’s instances. If the instance is launched into a default subnet, the default is to assign a public IPv4 address, unless you disabled the option to assign a public IPv4 address on the subnet. If the instance is launched into a nondefault subnet, the default is not to assign a public IPv4 address, unless you enabled the option to assign a public IPv4 address on the subnet.

    If you specify true, each instance in the Auto Scaling group receives a unique public IPv4 address. For more information, see Launching Auto Scaling instances in a VPC in the Amazon EC2 Auto Scaling User Guide.

    If you specify this property, you must specify at least one subnet for VPCZoneIdentifier when you create your group.

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

    Swift

    var associatePublicIpAddress: NSNumber? { get set }

  • The block device mapping entries that define the block devices to attach to the instances at launch. By default, the block devices specified in the block device mapping for the AMI are used. For more information, see Block device mappings in the Amazon EC2 User Guide for Linux Instances.

  • Specifies whether the launch configuration is optimized for EBS I/O (true) or not (false). The optimization provides dedicated throughput to Amazon EBS and an optimized configuration stack to provide optimal I/O performance. This optimization is not available with all instance types. Additional fees are incurred when you enable EBS optimization for an instance type that is not EBS-optimized by default. For more information, see Amazon EBS-optimized instances in the Amazon EC2 User Guide for Linux Instances.

    The default value is false.

    Swift

    var ebsOptimized: NSNumber? { get set }

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

    Swift

    var iamInstanceProfile: String? { get set }

  • The ID of the Amazon Machine Image (AMI) that was assigned during registration. For more information, see Finding a Linux AMI in the Amazon EC2 User Guide for Linux Instances.

    If you specify InstanceId, an ImageId is not required.

    Declaration

    Objective-C

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

    Swift

    var imageId: String? { get set }

  • The ID of the instance to use to create the launch configuration. The new launch configuration derives attributes from the instance, except for the block device mapping.

    To create a launch configuration with a block device mapping or override any other instance attributes, specify them as part of the same request.

    For more information, see Creating a launch configuration using an EC2 instance in the Amazon EC2 Auto Scaling User Guide.

    Declaration

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

    Swift

  • Controls whether instances in this group are launched with detailed (true) or basic (false) monitoring.

    The default value is true (enabled).

    When detailed monitoring is enabled, Amazon CloudWatch generates metrics every minute and your account is charged a fee. When you disable detailed monitoring, CloudWatch generates metrics every 5 minutes. For more information, see Configure Monitoring for Auto Scaling Instances in the Amazon EC2 Auto Scaling User Guide.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSAutoScalingInstanceMonitoring *_Nullable instanceMonitoring;

    Swift

    var instanceMonitoring: AWSAutoScalingInstanceMonitoring? { get set }

  • Specifies the instance type of the EC2 instance. For information about available instance types, see Available instance types in the Amazon EC2 User Guide for Linux Instances.

    If you specify InstanceId, an InstanceType is not required.

    Declaration

    Objective-C

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

    Swift

    var instanceType: String? { get set }

  • The ID of the kernel associated with the AMI.

    We recommend that you use PV-GRUB instead of kernels and RAM disks. For more information, see User provided kernels in the Amazon EC2 User Guide for Linux Instances.

    Declaration

    Objective-C

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

    Swift

    var kernelId: String? { get set }

  • The tenancy of the instance, either default or dedicated. An instance with dedicated tenancy runs on isolated, single-tenant hardware and can only be launched into a VPC. To launch dedicated instances into a shared tenancy VPC (a VPC with the instance placement tenancy attribute set to default), you must set the value of this property to dedicated. For more information, see Configuring instance tenancy with Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide.

    If you specify PlacementTenancy, you must specify at least one subnet for VPCZoneIdentifier when you create your group.
