      1. API Description

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

      The API is used to modify the attributes of an instance. Only the name and the associated security groups can be modified for now.

      • An attribute must be specified in the request.
      • "Instance name" is a custom name for easier management. Tencent Cloud does not use the name for online support or instance management.
      • Batch operations are supported. Each request can modify up to 100 instances.
      • When you modify the security groups associated with an instance is modified, the original security groups are disassociated.
      • You can use the API DescribeInstances to query the instance operation result. If the 'LatestOperationState' in the response is SUCCESS, the operation is successful.

      A maximum of 10 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.

      Action Yes String Common Params. The value used for this API: ModifyInstancesAttribute.
      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.
      InstanceIds.N Yes Array of String Instance ID(s). To obtain the instance IDs, you can call DescribeInstances and look for InstanceId in the response. The maximum number of instances in each request is 100.
      InstanceName No String The instance name, which can not exceed 60 characters

      Either InstanceName or SecurityGroups must be specified, but they can not be both specified.
      UserData No String User data provided to an instance, which needs to be encoded in Base64 format with a maximum size of 16 KB. For details on obtaining this parameter, refer to the startup commands for Windows and Linux.
      SecurityGroups.N No Array of String IDs of security groups associated with the specified instance. You can associate with a security group by adding its ID, or cancel the association with a security group by removing its ID.

      Either InstanceName or SecurityGroups must be specified, but they cannot be both set.
      CamRoleName No String The role bound with the instance. If it is not specified, it indicates to unbind the current role of the CVM.
      HostName No String Modified hostname of an instance.
    • Period (.) and hyphen (-) should not be used as the first or last character of the hostname, and should not be used consecutively.
    • Windows instances: The hostname should contain 2 to 15 characters, including letters (case insensitive), digits, and hyphens (-), does not support periods (.), and should not be all digits.
    • Instances of other types (such as Linux instances): The hostname should contain 2 to 60 characters, including multiple periods (.), with each segment between periods considered as one section. Each section can contain letters (case insensitive), digits, and hyphens (-).
      • Note: After the hostname is modified, the instance will restart immediately, and the new hostname will take effect after the restart.
      DisableApiTermination No Boolean Instance termination protection flag, indicating whether an instance is allowed to be deleted through an API. Valid values:
    • true: Instance protection is enabled, and the instance is not allowed to be deleted through the API.
    • false: Instance protection is disabled, and the instance is allowed to be deleted through the API.
      • Default value: false.
      CamRoleType No String The role type, which is used in conjunction with CamRoleName. The value is obtained in RoleType field, returning by CAM DescribeRoleList and GetRole APIs. Valid value: user, system and service_linked.
      For example, when LinkedRoleIn is contained in CamRoleName (such as TKE_QCSLinkedRoleInPrometheusService), the returned RoleType of DescribeRoleList and GetRoleis is service_linked, and the CamRoleType service_linked.
      When the value obtained in RoleType is user (default) or system, CamRoleType can be left empty.
      AutoReboot No Boolean Whether to automatically restart an instance when modifying a hostname. If not specified, the instance will automatically restart by default.
      - true: Modify the hostname and automatically restart the instance.
      - false: Modify the hostname without automatically restarting the instance. A manual restart is required for the new hostname to take effect.
      Note: This parameter is valid only when a hostname is modified.
