Setting Tags for an OpenSearch Cluster

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

Tags can be added during or after cluster creation. If you want to use the same tag to identify multiple cloud resources for better resource grouping, we recommend that you predefine tags in Tag Management Service (TMS). For details, see Predefined Tags Overview.

Constraints

  • Each cluster can have a maximum of 20 tags.
  • If your organization has configured tag policies for CSS, add tags to clusters based on these policies. If a tag does not comply with existing tag policies, cluster creation may fail. Contact the administrator to learn more about these policies.

Managing Tags

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

  1. Log in to the CSS management console.
  2. In the navigation pane on the left, choose Clusters > OpenSearch.
  3. In the cluster list, click the name of the target cluster. The cluster information page is displayed.
  4. Select the Tags tab, where you can add, modify, or delete tags.
    • View

      On the Tags page, you can view details about tags of the cluster, including the number of tags and the key and value of each tag.

    • Add

      Click Edit Tag in the upper left corner. In the displayed dialog box, click Add Tag, enter the tag key and value, and click OK.

    • Modify

      Click Edit Tag in the upper left corner. In the displayed dialog box, modify the key and value of a tag, and click OK.

    • Delete

      Click Edit Tag in the upper left corner. In the displayed dialog box, click Delete in the row that contains a tag, and click OK.

Searching for Clusters by Tag

  1. Log in to the CSS management console.
  2. In the navigation pane on the left, choose Clusters > OpenSearch.
  3. In the cluster list, click the search box, and select a tag key and value to search for the target cluster.

    You can select a tag key and value from the drop-down list. The system returns a list of clusters that exactly match the tag key and value. If you select multiple tags, only clusters including all of the selected tags will be returned.

    The filter can include a maximum of 10 tags.
