The information to include in the launch template.

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

See: newRequestLaunchTemplateData smart constructor.

Create a value of RequestLaunchTemplateData with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:blockDeviceMappings:RequestLaunchTemplateData', requestLaunchTemplateData_blockDeviceMappings - The block device mapping.

$sel:capacityReservationSpecification:RequestLaunchTemplateData', requestLaunchTemplateData_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).

$sel:cpuOptions:RequestLaunchTemplateData', requestLaunchTemplateData_cpuOptions - The CPU options for the instance. For more information, see Optimizing CPU Options in the Amazon Elastic Compute Cloud User Guide.

$sel:creditSpecification:RequestLaunchTemplateData', requestLaunchTemplateData_creditSpecification - The credit option for CPU usage of the instance. Valid only for T instances.

$sel:disableApiStop:RequestLaunchTemplateData', requestLaunchTemplateData_disableApiStop - Indicates whether to enable the instance for stop protection. For more information, see Stop Protection.

$sel:disableApiTermination:RequestLaunchTemplateData', requestLaunchTemplateData_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.

$sel:ebsOptimized:RequestLaunchTemplateData', requestLaunchTemplateData_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.

$sel:elasticGpuSpecifications:RequestLaunchTemplateData', requestLaunchTemplateData_elasticGpuSpecifications - An elastic GPU to associate with the instance.

$sel:elasticInferenceAccelerators:RequestLaunchTemplateData', requestLaunchTemplateData_elasticInferenceAccelerators - The elastic inference accelerator for the instance.

You can't enable Amazon Web Services Nitro Enclaves and hibernation on the same instance.

$sel:hibernationOptions:RequestLaunchTemplateData', requestLaunchTemplateData_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 instance in the Amazon Elastic Compute Cloud User Guide.

$sel:instanceMarketOptions:RequestLaunchTemplateData', requestLaunchTemplateData_instanceMarketOptions - The market (purchasing) option for the instances.

$sel:instanceRequirements:RequestLaunchTemplateData', requestLaunchTemplateData_instanceRequirements - The attributes for the instance types. When you specify instance attributes, Amazon EC2 will identify instance types with these attributes.

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

$sel:instanceType:RequestLaunchTemplateData', requestLaunchTemplateData_instanceType - The instance type. For more information, see Instance types in the Amazon Elastic Compute Cloud User Guide.

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

$sel:kernelId:RequestLaunchTemplateData', requestLaunchTemplateData_kernelId - The ID of the kernel.

We recommend that you use PV-GRUB instead of kernels and RAM disks. For more information, see User provided kernels in the Amazon Elastic Compute Cloud User Guide.

$sel:keyName:RequestLaunchTemplateData', requestLaunchTemplateData_keyName - The name of the key pair. You can create a key pair using CreateKeyPair or ImportKeyPair.

If you do not specify a key pair, you can't connect to the instance unless you choose an AMI that is configured to allow users another way to log in.

$sel:monitoring:RequestLaunchTemplateData', requestLaunchTemplateData_monitoring - The monitoring for the instance.

$sel:networkInterfaces:RequestLaunchTemplateData', requestLaunchTemplateData_networkInterfaces - One or more network interfaces. If you specify a network interface, you must specify any security groups and subnets as part of the network interface.

$sel:placement:RequestLaunchTemplateData', requestLaunchTemplateData_placement - The placement for the instance.

$sel:privateDnsNameOptions:RequestLaunchTemplateData', requestLaunchTemplateData_privateDnsNameOptions - The options for the instance hostname. The default values are inherited from the subnet.

$sel:ramDiskId:RequestLaunchTemplateData', requestLaunchTemplateData_ramDiskId - The ID of the RAM disk.

We recommend that you use PV-GRUB instead of kernels and RAM disks. For more information, see User provided kernels in the Amazon Elastic Compute Cloud User Guide.

You can specify tags for the following resources only:

• Instances
• Volumes
• Elastic graphics
• Spot Instance requests
