Managing Tags¶
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 select a predefined tag and set Tag value for the tag. You can click View Predefined Tag to switch to the TMS management console and view existing tags.
You can also create new tags by specifying Tag key and Tag value.
You can add a maximum of 10 tags for a CSS cluster. If the entered tag is incorrect, you can click Delete on the right of the tag to delete the tag.
