Setting Tags for an OpenSearch Cluster

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.

Constraints

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

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