1. API Description

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

This API (UpgradeLaunchConfiguration) is used to upgrade a launch configuration.

  • This API is used to upgrade a launch configuration in a "completely overriding" manner, i.e., it uniformly sets a new configuration according to the API parameters regardless of the original parameters. If optional fields are left empty, their default values will be used.
  • After the launch configuration is upgraded, the existing instances that have been created by it will not be changed, but new instances will be created according to the new configuration.

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

Note: This API supports Finance regions. If the common parameter Region is a Finance region, a domain name with the Finance region needs to be specified, for example: as.ap-shanghai-fsi.tencentcloudapi.com

  • Public images
  • Custom images
  • Shared images
  • Marketplace images

    • You can obtain the available image IDs in the following ways:
  • For public images, custom images, and shared images, log in to the console to query the image IDs; for marketplace images, query the image IDs through Cloud Marketplace.
  • This value can be obtained from the ImageId field in the return value of the DescribeImages API.

    InstanceMarketOptions No InstanceMarketOptionsRequest Market-related options of the instance, such as the parameters related to stop instances. If the billing method of instance is specified as bidding, this parameter must be passed in.
    InstanceTypesCheckPolicy No String Instance type verification policy. Value range: ALL, ANY. Default value: ANY.

  • ALL: The verification will success only if all instance types (InstanceType) are available; otherwise, an error will be reported.

  • ANY: The verification will success if any instance type (InstanceType) is available; otherwise, an error will be reported.

    Common reasons why an instance type is unavailable include stock-out of the instance type and the corresponding cloud disk.
