In the following section, we will cover how to specify a tag pruning policy and set a tag limit on repositories that you manage. It will not include modifying or deleting a tag pruning policy.
## Specify a tag pruning policy
As a repository administrator, you can now add tag pruning policies on each repository that you manage. To get started, navigate to `https://<dtr-url>` and log in with your credentials.

Specify one or more image attributes to add to your pruning criteria, then choose **Prune future tags** to apply your selection to future tags or **Prune all tags** to evaluate existing tags on your repository.

All tag pruning policies on your account are evaluated every 15 minutes. Any qualifying tags are then deleted from the metadata store. If a tag pruning policy is modified or created, then the tag pruning policy for the *affected* repository will be evaluated.
This does not cover modifying or deleting a tag pruning policy.
## Set a tag limit
In addition to pruning policies, you can also set tag limits on repositories that you manage to restrict the number of tags on a given repository. Repository tag limits are processed in a first in first out (FIFO) manner. For example, if you set a tag limit of 2, adding a third tag would push out the first.
