TagResources - Auto Scaling - Alibaba Cloud Documentation Center

Creates and binds tags to a list of specified Auto Scaling resources.

Operation description

A maximum of 20 tags can be bound to a scaling group.

Note
Before binding tags, Alibaba Cloud verifies the number of existing tags on the resource. If the limit is exceeded, an error message is returned.
If the Tag.N.Propagate parameter is set to true, tags configured on the scaling group are propagated only to instances that are about to be created in the scaling group, not to instances that are already running in the scaling group.
If tags are configured in the scaling configuration and tags configured on the scaling group are set to propagate, instance tags on newly created instances are expected to be as follows:
- The instances contain all tags from both the scaling configuration and the scaling group.
- If a tag configured in the scaling configuration has the same tag key as a tag propagated from the scaling group, instance tag propagated from the scaling group is overwritten by instance tag configured in the scaling configuration.

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.
