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.

Parameter Name Required Type Description
Action Yes String Common Params. The value used for this API: CreateLaunchTemplateVersion.
Version Yes String Common Params. The value used for this API: 2017-03-12.
Region Yes String Common Params. For more information, please see the list of regions supported by the product.
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)
LaunchTemplateId Yes String Instance launch template ID. This parameter is used as a basis for creating new template versions.
LaunchTemplateVersion No Integer This parameter, when specified, is used to create instance launch templates. If this parameter is not specified, the default version will be used.
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.
  • ImageId No 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.
  • SystemDisk No SystemDisk System disk configuration of the instance. If this parameter is not specified, the default value will be used.
    DataDisks.N No Array of DataDisk The configuration information of instance data disks. If this parameter is not specified, no data disk will be purchased by default. When purchasing, you can specify 21 data disks, which can contain at most 1 LOCAL_BASIC or LOCAL_SSD data disk, and at most 20 CLOUD_BASIC, CLOUD_PREMIUM, or CLOUD_SSD data disks.
    VirtualPrivateCloud No VirtualPrivateCloud Configuration information of VPC. This parameter is used to specify VPC ID and subnet ID, etc. If this parameter is not specified, the classic network is used by default. If a VPC IP is specified in this parameter, it indicates the primary ENI IP of each instance. The value of parameter InstanceCount must be same as the number of VPC IPs, which cannot be greater than 20.
    InternetAccessible No InternetAccessible Configuration of public network bandwidth. If this parameter is not specified, 0 Mbps will be used by default.
    InstanceCount No Integer Number of instances to be purchased. Value range for monthly-subscribed instances: [1, 300]. Value range for pay-as-you-go instances: [1, 100]. Default value: 1. 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.
  • LoginSettings No LoginSettings Login settings of the instance. You can use this parameter to set the login method, password, and key of the instance or keep the login settings of the original image. By default, a random password will be generated and sent to you via the Message Center.
    SecurityGroupIds.N No Array of String Security groups to which the instance belongs. To obtain the security group IDs, you can call DescribeSecurityGroups and look for the sgld fields in the response. If this parameter is not specified, the instance will be associated with default security groups.
    EnhancedService No EnhancedService Enhanced service. You can use this parameter to specify whether to enable services such as Anti-DDoS and Cloud Monitor. If this parameter is not specified, Cloud Monitor and Anti-DDoS are enabled for public images by default. However, for custom images and images from the marketplace, Anti-DDoS and Cloud Monitor are not enabled by default. The original services in the image will be retained.

    DryRun No Boolean Whether the request is a dry run only.
    true: dry run only. The request will not create instance(s). A dry run can check whether all the required parameters are specified, whether the request format is right, whether the request exceeds service limits, and whether the specified CVMs are available.
    If the dry run fails, the corresponding error code will be returned.
    If the dry run succeeds, the RequestId will be returned.
