Managing Tags

Tags facilitate Nacos engine identification and management.

If your organization has configured tag policies for Nacos engines, add tags to engines based on the policies. If a tag does not comply with the tag policies, engine creation may fail. Contact your administrator to learn more about tag policies.

You can add tags to a Nacos engine when creating the engine or add tags on the details page of the created engine. Up to 20 tags can be added to an engine. Tags can be modified and deleted.

A tag consists of a tag key and a tag value. Table 1 lists the tag key and value requirements.
