Virtual Private Cloud:TagResources

Last Updated:Oct 26, 2026

Creates and attaches tags to one or more specified VPC peering connections.

Operation description

Tags are labels that you assign to instances. Instance tag consists of a key-value pair. Take note of the following limits on tags:

  • The key of instance tag on an instance must be unique.

  • Tags must be attached to instances. Unattached tags are not supported.

  • Tag information is not shared across regions.

    For example, tags created in the China (Hangzhou) region are not visible in the China (Shanghai) region.

  • Within the same account and region, tag information is shared across different VPC peering connections.

     For example, if a tag is attached to a VPC peering connection within the same account and region, you can directly select and attach this tag to other VPC peering connections on the Edit Tags page without manually entering the key-value pair. You can modify the key and value of a tag, or delete the tag from an instance at any time. If an instance is deleted, all tags attached to the instance are also deleted.
    
  • You can attach up to 20 tags to a single instance. Before attaching tags, Alibaba Cloud verifies the number of existing tags on the resource. If the limit is exceeded, an error message is returned.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

  • Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.

  • API: The API that you can call to perform the action.

  • Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.

  • Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.

    • For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.

    • For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.

  • Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.

  • Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
