POST /#Action=CreateLaunchTemplateVersion

Creates a new version of a launch template. You can specify an existing version of launch template from which to base the new version.

Launch template versions are numbered in the order in which they are created. You cannot specify, change, or replace the numbering of launch template versions.

Launch templates are immutable; after you create a launch template, you can't modify it. Instead, you can create a new version of the launch template that includes any changes you require.

For more information, see Modify a launch template (manage launch template versions) in the Amazon Elastic Compute Cloud User Guide.

Name	Type	Required	Description
`ResolveAlias`	Boolean	No	If `true`, and if a Systems Manager parameter is specified for `ImageId`, the AMI ID is displayed in the response for `imageID`. For more information, see Use a Systems Manager parameter instead of an AMI ID in the Amazon Elastic Compute Cloud User Guide. Default: `false`
