Consistently Tagging CVM, Cloud Disk, Public IP, and Elastic NIC in Tencent Cloud

This article from the Tencent Cloud Developer Community explains how to assign the same tag to a CVM instance, its attached cloud disk, the public IP (non‑EIP) and the elastic network interface (ENI) when creating the CVM.

Requirement: Create a CVM and bind identical tags to the CVM, its cloud disk, public IP, and elastic NIC.

Step 1 – Tag CVM and Cloud Disk: Use the RunInstances API and specify the TagSpecification field for the resource types instance (CVM) and cloudDisk . The API Explorer URL is https://console.cloud.tencent.com/api/explorer?Product=cvm&Version=2017-03-12&Action=RunInstances.

Limitation: The RunInstances API does not support tagging the public IP and ENI directly; it only accepts the instance prefix for tags, so attempts to use eip or eni result in errors.

Step 2 – Retrieve IDs of Public IP and ENI: Call the DescribeAddresses API with a Filters block that includes instance-id and address-type . This returns the IDs of the public IP and the associated ENI. API Explorer URL: http://console.cloud.tencent.com/api/explorer?Product=vpc&Version=2017-03-12&Action=DescribeAddresses.

Step 3 – Tag Public IP and ENI: Use the TagResources (or AttachResourcesTag ) API to bind the same tag to the retrieved public IP and ENI IDs. API Explorer URL: http://console.cloud.tencent.com/api/explorer?Product=tag&Version=2018-08-13&Action=AttachResourcesTag. Detailed usage is documented at http://cloud.tencent.com/document/product/651/46294.

The article includes screenshots of the API Explorer calls, the DryRun results, and the final tagging verification.

By following these steps, developers can ensure that all resources created together share a consistent tag, which simplifies resource management and cost allocation in Tencent Cloud.
