Note

You must specify at least one parameter for the launch template data.

BlockDeviceMappings

The block device mapping.

Type: Array of LaunchTemplateBlockDeviceMappingRequest objects

Required: No

CapacityReservationSpecification

Type: LaunchTemplateCapacityReservationSpecificationRequest object

Required: No

CpuOptions

The CPU options for the instance. For more information, see Optimize CPU options in the Amazon EC2 User Guide.

Type: Boolean

Required: No

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.

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

ElasticGpuSpecifications

Deprecated.

Note

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.

Type: Array of ElasticGpuSpecification objects

Required: No

ElasticInferenceAccelerators

Note

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.

Note

Starting April 15, 2023, AWS 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.

Type: Array of LaunchTemplateElasticInferenceAccelerator objects

Required: No

EnclaveOptions

Indicates whether the instance is enabled for AWS Nitro Enclaves. For more information, see What is AWS Nitro Enclaves? in the AWS Nitro Enclaves User Guide.

You can't enable AWS Nitro Enclaves and hibernation on the same instance.

Type: LaunchTemplateEnclaveOptionsRequest object

Required: No

HibernationOptions

Indicates whether an instance is enabled for hibernation. This parameter is valid only if the instance meets the hibernation prerequisites. For more information, see Hibernate your Amazon EC2 instance in the Amazon EC2 User Guide.

Type: LaunchTemplateHibernationOptionsRequest object

Required: No

IamInstanceProfile

The name or Amazon Resource Name (ARN) of an IAM instance profile.

Type: LaunchTemplateIamInstanceProfileSpecificationRequest 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 in the Amazon EC2 User Guide.

Note

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 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.

Note

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 AWS CloudFormation resource, you can't specify InstanceRequirements.

For more information, see Specify attributes for instance type selection for EC2 Fleet or Spot Fleet and Spot placement score in the Amazon EC2 User Guide.
