Deletes versions of a launch template. When you call this operation, you can specify parameters, such as LaunchTemplateId and DeleteVersion, in the request.

Operation description

Take note of the following items:

You cannot delete the default version of a launch template by calling this operation. To delete the default version of a launch template, you must delete the launch template.
If the version of a launch template that you want to delete is the default version, call the ModifyLaunchTemplateDefaultVersion operation or go to the Launch Templates page in the Elastic Compute Service (ECS) console to change the default version to a different version, and then delete the original default version.
After you delete a version of a launch template, the ECS instances that were created based on the version are not affected.
