Type: Array of [LaunchTemplateBlockDeviceMappingRequest](API_LaunchTemplateBlockDeviceMappingRequest.md) objects Required: No ** CapacityReservationSpecification ** The Capacity Reservation targeting option. If you do not specify this parameter, the instance's Capacity Reservation preference defaults to `open`, which enables it to run in any open Capacity Reservation that has matching attributes (instance type, platform, Availability Zone). Type: [LaunchTemplateCapacityReservationSpecificationRequest](API_LaunchTemplateCapacityReservationSpecificationRequest.md) object Required: No ** CpuOptions ** The CPU options for the instance. For more information, see [CPU options for Amazon EC2 instances](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-optimize-cpu.html) in the *Amazon EC2 User Guide*. Type: [LaunchTemplateCpuOptionsRequest](API_LaunchTemplateCpuOptionsRequest.md) object Required: No ** CreditSpecification ** The credit option for CPU usage of the instance. Valid only for T instances. Type: [CreditSpecificationRequest](API_CreditSpecificationRequest.md) object Required: No ** DisableApiStop ** Indicates whether to enable the instance for stop protection. For more information, see [Enable stop protection for your EC2 instances](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-stop-protection.html) in the *Amazon EC2 User Guide*. Type: Boolean Required: No ** DisableApiTermination ** Indicates whether termination protection is enabled for the instance. The default is `false`, which means that you can terminate the instance using the Amazon EC2 console, command line tools, or API. You can enable termination protection when you launch an instance, while the instance is running, or while the instance is stopped. Type: Boolean Required: No ** EbsOptimized ** Indicates whether the instance is optimized for Amazon EBS I/O. This optimization provides dedicated throughput to Amazon EBS and an optimized configuration stack to provide optimal Amazon EBS I/O performance. This optimization isn't available with all instance types. Additional usage charges apply when using an EBS-optimized instance. Type: Boolean Required: No ** ElasticGpuSpecification.N ** Deprecated. Amazon Elastic Graphics reached end of life on January 8, 2024. Type: Array of [ElasticGpuSpecification](API_ElasticGpuSpecification.md) objects Required: No ** ElasticInferenceAccelerator.N ** *This member has been deprecated.* Amazon Elastic Inference is no longer available. 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. Type: Array of [LaunchTemplateElasticInferenceAccelerator](API_LaunchTemplateElasticInferenceAccelerator.md) objects Required: No ** EnclaveOptions ** Indicates whether the instance is enabled for AWS Nitro Enclaves. For more information, see [What is Nitro Enclaves?](https://docs.aws.amazon.com/enclaves/latest/user/nitro-enclave.html) in the * AWS Nitro Enclaves User Guide*. You can't enable AWS Nitro Enclaves and hibernation on the same instance. Type: [LaunchTemplateEnclaveOptionsRequest](API_LaunchTemplateEnclaveOptionsRequest.md) object Required: No ** HibernationOptions ** Indicates whether an instance is enabled for hibernation. This parameter is valid only if the instance meets the [hibernation prerequisites](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/hibernating-prerequisites.html). For more information, see [Hibernate your Amazon EC2 instance](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Hibernate.html) in the *Amazon EC2 User Guide*. Type: [LaunchTemplateHibernationOptionsRequest](API_LaunchTemplateHibernationOptionsRequest.md) object Required: No ** IamInstanceProfile ** The name or Amazon Resource Name (ARN) of an IAM instance profile. Type: [LaunchTemplateIamInstanceProfileSpecificationRequest](API_LaunchTemplateIamInstanceProfileSpecificationRequest.md) object Required: No ** ImageId ** The ID of the AMI in the format `ami-0ac394d6a3example`. Alternatively, you can specify a Systems Manager parameter, using one of the following formats. The Systems Manager parameter will resolve to an AMI ID on launch. To reference a public parameter: + `resolve:ssm:public-parameter ` To reference a parameter stored in the same account: + `resolve:ssm:parameter-name ` + `resolve:ssm:parameter-name:version-number ` + `resolve:ssm:parameter-name:label ` To reference a parameter shared from another AWS account: + `resolve:ssm:parameter-ARN ` + `resolve:ssm:parameter-ARN:version-number ` + `resolve:ssm:parameter-ARN:label ` For more information, see [Use a Systems Manager parameter instead of an AMI ID](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/create-launch-template.html#use-an-ssm-parameter-instead-of-an-ami-id) in the *Amazon EC2 User Guide*. If the launch template will be used for an EC2 Fleet or Spot Fleet, note the following: + Only EC2 Fleets of type `instant` support specifying a Systems Manager parameter. + For EC2 Fleets of type `maintain` or `request`, or for Spot Fleets, you must specify the AMI ID. Type: String Required: No ** InstanceInitiatedShutdownBehavior ** Indicates whether an instance stops or terminates when you initiate shutdown from the instance (using the operating system command for system shutdown). Default: `stop` Type: String Valid Values: `stop | terminate` Required: No ** InstanceMarketOptions ** The market (purchasing) option for the instances. Type: [LaunchTemplateInstanceMarketOptionsRequest](API_LaunchTemplateInstanceMarketOptionsRequest.md) object Required: No ** 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](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-launch-instance-wizard.html), or with the [RunInstances](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_RunInstances.html) API or [AWS::EC2::Instance](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-instance.html) AWS CloudFormation resource, you can't specify `InstanceRequirements`. For more information, see [Specify attributes for instance type selection for EC2 Fleet or Spot Fleet](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-fleet-attribute-based-instance-type-selection.html) and [Spot placement score](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-placement-score.html) in the *Amazon EC2 User Guide*. Type: [InstanceRequirementsRequest](API_InstanceRequirementsRequest.md) object Required: No ** InstanceType ** The instance type. For more information, see [Amazon EC2 instance types](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html) in the *Amazon EC2 User Guide*. If you specify `InstanceType`, you can't specify `InstanceRequirements`.
