AWSEC2FleetLaunchTemplateOverridesRequest

Objective-C

@interface AWSEC2FleetLaunchTemplateOverridesRequest

Swift

class AWSEC2FleetLaunchTemplateOverridesRequest

Describes overrides for a launch template.

  • The Availability Zone in which to launch the instances.

    Declaration

    Objective-C

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

    Swift

    var availabilityZone: String? { get set }

  • The ID of the AMI. An AMI is required to launch an instance. The AMI ID must be specified here or in the launch template.

    Declaration

    Objective-C

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

    Swift

    var imageId: String? { get set }

  • The attributes for the instance types. When you specify instance attributes, Amazon EC2 will identify instance types with those attributes.

    If you specify InstanceRequirements, you can’t specify InstanceType.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSEC2InstanceRequirementsRequest *_Nullable instanceRequirements;

    Swift

    var instanceRequirements: AWSEC2InstanceRequirementsRequest? { get set }

  • The instance type.

    mac1.metal is not supported as a launch template override.

    If you specify InstanceType, you can’t specify InstanceRequirements.

    Declaration

    Objective-C

    @property (nonatomic) AWSEC2InstanceType instanceType;

    Swift

    var instanceType: AWSEC2InstanceType { get set }

  • The maximum price per unit hour that you are willing to pay for a Spot Instance. We do not recommend using this parameter because it can lead to increased interruptions. If you do not specify this parameter, you will pay the current Spot price.

    If you specify a maximum price, your instances will be interrupted more frequently than if you do not specify this parameter.

    Declaration

    Objective-C

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

    Swift

    var maxPrice: String? { get set }

  • The location where the instance launched, if applicable.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSEC2Placement *_Nullable placement;

    Swift

    var placement: AWSEC2Placement? { get set }

  • The priority for the launch template override. The highest priority is launched first.

    If the On-Demand AllocationStrategy is set to prioritized, EC2 Fleet uses priority to determine which launch template override to use first in fulfilling On-Demand capacity.

    If the Spot AllocationStrategy is set to capacity-optimized-prioritized, EC2 Fleet uses priority on a best-effort basis to determine which launch template override to use in fulfilling Spot capacity, but optimizes for capacity first.

    Valid values are whole numbers starting at 0. The lower the number, the higher the priority. If no number is set, the launch template override has the lowest priority. You can set the same priority for different launch template overrides.

    Declaration

    Objective-C

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

    Swift

    var priority: NSNumber? { get set }

  • The IDs of the subnets in which to launch the instances. Separate multiple subnet IDs using commas (for example, subnet-1234abcdeexample1, subnet-0987cdef6example2). A request of type instant can have only one subnet ID.

    Declaration

    Objective-C

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

    Swift

    var subnetId: String? { get set }

  • The number of units provided by the specified instance type.

    Declaration

    Objective-C

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

    Swift

    var weightedCapacity: NSNumber? { get set }
