Tags are cluster identifiers. Adding tags to clusters can help you identify and manage your cluster resources.

You can add tags to a cluster when creating the cluster or add them on the details page of the created cluster.

You can create a maximum of 20 tags for a CSS cluster.

In CSS, you can add, delete, modify, and query cluster tags.
