Managing Tags

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

If your organization has enabled tag policies for CSS, you must comply with the tag policy rules when creating clusters, otherwise, clusters may fail to be created. Contact the organization administrator to learn more about tag policies.
