      1. API Description

      Domain name for API request: cvm.tencentcloudapi.com.

      This API is used to create an instance launch template.

      An instance launch template contains the configuration information required to create an instance, including instance type, data/system disk type and size, and security group, etc.

      When a template is created, it defaults to Version 1. You can use CreateLaunchTemplateVersion to create new versions of this template, with the version number increasing. When you run RunInstances to create instances, you can specify the instance launch template version. If it’s not specified, the default template version is used.

      A maximum of 20 requests can be initiated per second for this API.

      We recommend you to use API Explorer
      Try it
      API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

      2. Input Parameters

      The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.
      This document describes the parameters for Signature V1. It's recommended to use the V3 signature, which provides higher security. Note that for Signature V3, the common parameters need to be placed in the HTTP Header. See details.

      Parameter Name Required Type Description
      Action Yes String Common parameter. The value used for this API: CreateLaunchTemplate.
      Version Yes String Common parameter. The value used for this API: 2017-03-12.
      Region Yes String Common parameter. For more information, please see the list of regions supported by the product.
      LaunchTemplateName Yes String Instance launch template name. It can include 2-128 characters.
      Placement Yes Placement Location of the instance. You can use this parameter to specify the attributes of the instance, such as its availability zone, project, and CDH (for dedicated CVMs)
      ImageId Yes String The image ID in the format of img-xxx. There are four types of images:
    • Public images
    • Custom images
    • Shared images
    • Marketplace images (for Chinese mainland only)

      • To check the image ID:
    • For public images, custom images, and shared images, go to the console. For marketplace images, go to Cloud Marketplace.
    • Call DescribeImages, pass in InstanceType to retrieve the list of images supported by the current model, and then find the ImageId in the response.
      		•
      LaunchTemplateVersionDescription No String Description of instance launch template versions. This parameter can contain 2-256 characters.
      InstanceType No String The instance model. Different resource specifications are specified for different instance models.

    • To view specific values for PREPAID or POSTPAID_BY_HOUR instances, you can call DescribeInstanceTypeConfigs or refer to Instance Types. If this parameter is not specified, the system will specify the default model according to the dynamic resource sales in the current region.
    • For CDHPAID instances, the value of this parameter is in the format of CDH_XCXG based on the number of CPU cores and memory capacity. For example, if you want to create a CDH instance with a single-core CPU and 1 GB memory, you need to specify this parameter as CDH_1C1G.

The specified number of instances to be purchased cannot exceed the remaining quota allowed for the user. For more information on quota, see CVM instance Purchase Limits.
      InstanceName No String Instance name to be displayed.
    • If this parameter is not specified, "Unnamed" will be displayed by default.
    • If you purchase multiple instances at the same time and specify a pattern string {R:x}, numbers [x, x+n-1] will be generated, where n represents the number of instances purchased. For example, you specify a pattern string, server_{R:3}. If you only purchase 1 instance, the instance will be named server_3; if you purchase 2, they will be named server_3 and server_4. You can specify multiple pattern strings in the format of {R:x}.
    • If you purchase multiple instances at the same time and do not specify a pattern string, the instance names will be suffixed by 1, 2...n, where n represents the number of instances purchased. For example, if you purchase 2 instances and the instance name body is server_, the instance names will be server_1 and server_2.
    • This parameter can contain up to 60 characters, including the pattern string.
      		•
