In the DDS, you can delete tags created by yourself in the DDS.
Log in to the DDS console.
Click System Management -> Tag Management on the left to go to the Tag Management page.
Locate the tag you want to delete, and search for the specified tag in the tag key or tag value search box.
In the corresponding tag row, you can see the Delete button in the Operation column, and click Delete.
Click Confirm in the pop-up window to delete the tag.
Note:
To delete a tag in Tag Management, unbind it from the bound instance first. Otherwise, a message is displayed indicating that the tag cannot be deleted.
The Tag Management page is not supported by all resource pools. The support for this page may differ depending on resource pools.
