  • Shared images

  • You can obtain the image IDs in the CVM console.
  • You can also use the DescribeImages and look for ImageId in the response.
  • ProjectId No Integer Project ID of the launch configuration. The default project is used if it’s left blank.
    Note that this project ID is not the same as the project ID of the scaling group.
    InstanceType No String Instance model. Different instance models specify different resource specifications. The specific value can be obtained by calling the DescribeInstanceTypeConfigs API to get the latest specification table or referring to the descriptions in Instance Types.
    InstanceType and InstanceTypes are mutually exclusive, and one and only one of them must be entered.
    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 Information of the instance's data disk configuration. If this parameter is not specified, no data disk is purchased by default. Up to 11 data disks can be supported.
    InternetAccessible No InternetAccessible Configuration of public network bandwidth. If this parameter is not specified, 0 Mbps will be used by default.
    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 The security group to which the instance belongs. This parameter can be obtained by calling the SecurityGroupId field in the returned value of DescribeSecurityGroups. If this parameter is not specified, no security group will be bound by default.

    4. Example

    Example1 Creating a launch configuration with required parameters

    This example shows you how to create a launch configuration by only assigning values for the required parameters (launch configuration name, instance model, and image ID) and using system default values for other parameters. The specific configuration is as follows: launch configuration name: as_test; instance model: Standard II 1C1G (S2.SMALL1); image ID: img-8toqc6s3.

    Input Example

    POST / HTTP/1.1
    Host: as.tencentcloudapi.com
    Content-Type: application/json
    X-TC-Action: CreateLaunchConfiguration
    <Common request parameters>
