Managing Tags

Scenarios

Tag Management Service (TMS) enables you to use tags on the management console to manage resources. TMS works with other cloud services to manage tags. TMS manages tags globally and other cloud services manage their own tags.

Adding tags to GaussDB NoSQL instances helps you better identify and manage them. An instance can be tagged during or after it is created.

After an instance is tagged, you can search for the tag key or value to quickly query the instance details.

Precautions

  • You are advised to set predefined tags on the TMS console.

  • A tag consists of a key and value. You can add only one value for each key. For details about the naming rules of tag keys and tag values, see Table 1.

  • Up to 20 tags can be added for each instance.
