Cluster tags

Usage notes

• A tag is a key-value pair that consists of a tag key and a tag value.

• Tag keys must be unique for each cluster.

• You can bind a maximum of 20 tags to each cluster.

• When you unbind a tag from a cluster, the tag is automatically deleted if it is not bound to any other cluster.

Bind tags

1. Log on to the PolarDB console. In the left-side navigation pane, click Clusters, select the region of the target cluster.

2. Hover over the icon in the Tag column of the target cluster and click Bind.

3. In the Modify Tags dialog box, enter a tag key and tag value, and then click OK.

   Note

   After you create a tag, you can bind it to other clusters.

Filter clusters by tag

1. Log on to the PolarDB console. In the left-side navigation pane, click cluster list and select a region.

2. To Filter by Tag, click the Filter by Tag drop-down button in the upper-right corner of the cluster list page. In the displayed panel, use the Search by Tag Key and Search by Tag Value fields to find a tag. Select a tag key and value, such as the key tagKey1 and the value tagValue, to filter the clusters.
