| Attribute | Type | Required | Description |
| --------- | ---- | -------- | ----------- |
| `id`      | integer/string | yes | The ID or [URL-encoded path of the project](README.md#namespaced-path-encoding) owned by the authenticated user. |
| `repository_id` | integer | yes | The ID of registry repository. |
| `name_regex` | string | yes | The regex of the name to delete. To delete all tags specify `.*`. |
| `keep_n` | integer | no | The amount of latest tags of given name to keep. |
| `older_than` | string | no | Tags to delete that are older than the given time, written in human readable form `1h`, `1d`, `1month`. |

This API call performs the following operations:

1. It orders all tags by creation date. The creation date is the time of the
   manifest creation, not the time of tag push.
1. It removes only the tags matching the given `name_regex`.
1. It never removes the tag named `latest`.
1. It keeps N latest matching tags (if `keep_n` is specified).
1. It only removes tags that are older than X amount of time (if `older_than` is specified).
1. It schedules the asynchronous job to be executed in the background.

These operations are executed asynchronously and it might
take time to get executed. You can run this at most
once an hour for a given container repository.

NOTE: **Note:**
Due to a [Docker Distribution deficiency](https://gitlab.com/gitlab-org/gitlab-ce/issues/21405),
it doesn't remove tags whose manifest is shared by multiple tags.

Examples:

1. Remove tag names that are matching the regex (Git SHA), keep always at least 5,
   and remove ones that are older than 2 days:

   ```bash
   curl --request DELETE --data 'name_regex=[0-9a-z]{40}' --data 'keep_n=5' --data 'older_than=2d' --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/5/registry/repositories/2/tags"
   ```

2. Remove all tags, but keep always the latest 5:

   ```bash
   curl --request DELETE --data 'name_regex=.*' --data 'keep_n=5' --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/5/registry/repositories/2/tags"
   ```

3. Remove all tags that are older than 1 month:

   ```bash
   curl --request DELETE --data 'name_regex=.*' --data 'older_than=1month' --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/5/registry/repositories/2/tags"
   ```
