                    disableApiTermination

If you set this parameter to true, you can’t terminate the instance using the Amazon EC2 console, CLI, or API; otherwise, you can. To change this attribute after launch, use ModifyInstanceAttribute. Alternatively, if you set InstanceInitiatedShutdownBehavior to terminate, you can terminate the instance by running the shutdown command from the instance.

                    elasticGpuSpecifications

Deprecated.

Amazon Elastic Graphics reached end of life on January 8, 2024. For workloads that require graphics acceleration, we recommend that you use Amazon EC2 G4ad, G4dn, or G5 instances.

Swift

var elasticGpuSpecifications: [AWSEC2ElasticGpuSpecification]? { get set }


                    
                    
                    elasticInferenceAccelerators

An elastic inference accelerator to associate with the instance. Elastic inference accelerators are a resource you can attach to your Amazon EC2 instances to accelerate your Deep Learning (DL) inference workloads.

You cannot specify accelerators from different generations in the same request.

Starting April 15, 2023, Amazon Web Services will not onboard new customers to Amazon Elastic Inference (EI), and will help current customers migrate their workloads to options that offer better price and performance. After April 15, 2023, new customers will not be able to launch instances with Amazon EI accelerators in Amazon SageMaker, Amazon ECS, or Amazon EC2. However, customers who have used Amazon EI at least once during the past 30-day period are considered current customers and will be able to continue using the service.

Declaration

Objective-C

@property (nonatomic, strong) NSArray<AWSEC2LaunchTemplateElasticInferenceAccelerator *> *_Nullable elasticInferenceAccelerators;

Swift

var elasticInferenceAccelerators: [AWSEC2LaunchTemplateElasticInferenceAccelerator]? { get set }

                    imageId

The ID of the AMI. Alternatively, you can specify a Systems Manager parameter, which will resolve to an AMI ID on launch.

Valid formats:

ami-17characters00000
resolve:ssm:parameter-name
resolve:ssm:parameter-name:version-number
resolve:ssm:parameter-name:label
resolve:ssm:public-parameter

Currently, EC2 Fleet and Spot Fleet do not support specifying a Systems Manager parameter. If the launch template will be used by an EC2 Fleet or Spot Fleet, you must specify the AMI ID.

For more information, see Use a Systems Manager parameter instead of an AMI ID in the Amazon EC2 User Guide.

Declaration

Objective-C

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

                    instanceRequirements

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

You must specify VCpuCount and MemoryMiB. All other attributes are optional. Any unspecified optional attribute is set to its default.

When you specify multiple attributes, you get instance types that satisfy all of the specified attributes. If you specify multiple values for an attribute, you get instance types that satisfy any of the specified values.

To limit the list of instance types from which Amazon EC2 can identify matching instance types, you can use one of the following parameters, but not both in the same request:

AllowedInstanceTypes - The instance types to include in the list. All other instance types are ignored, even if they match your specified attributes.
ExcludedInstanceTypes - The instance types to exclude from the list, even if they match your specified attributes.

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

Attribute-based instance type selection is only supported when using Auto Scaling groups, EC2 Fleet, and Spot Fleet to launch instances. If you plan to use the launch template in the launch instance wizard, or with the RunInstances API or AWS::EC2::Instance Amazon Web Services CloudFormation resource, you can’t specify InstanceRequirements.

For more information, see Attribute-based instance type selection for EC2 Fleet, Attribute-based instance type selection for Spot Fleet, and Spot placement score in the Amazon EC2 User Guide.
