This action does not delete blobs. In order to delete them and recycle disk space,
[run the garbage collection](https://docs.gitlab.com/omnibus/maintenance/README.html#removing-unused-layers-not-referenced-by-manifests).

## Delete registry repository tags in bulk

Delete registry repository tags in bulk based on given criteria.

```plaintext
DELETE /projects/:id/registry/repositories/:repository_id/tags
```

| 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 | no | The [re2](https://github.com/google/re2/wiki/Syntax) regex of the name to delete. To delete all tags specify `.*`. **Note:** `name_regex` is deprecated in favor of `name_regex_delete`.|
| `name_regex_delete` | string | yes | The [re2](https://github.com/google/re2/wiki/Syntax) regex of the name to delete. To delete all tags specify `.*`.|
| `name_regex_keep` | string | no | The [re2](https://github.com/google/re2/wiki/Syntax) regex of the name to keep. This value will override any matches from `name_regex_delete`. Note: setting to `.*` will result in a no-op. |
| `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_delete` (or deprecated `name_regex`), keeping any that match `name_regex_keep`.
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.
This action does not delete blobs. In order to delete them and recycle disk space,
[run the garbage collection](https://docs.gitlab.com/omnibus/maintenance/README.html#removing-unused-layers-not-referenced-by-manifests).

NOTE: **Note:**
Since GitLab 12.4, individual tags are deleted.
For more details, see the [discussion](https://gitlab.com/gitlab-org/gitlab/issues/15737).

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:

   ```shell
   curl --request DELETE --data 'name_regex_delete=[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"
   ```

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

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

1. Remove all tags, but keep always tags beginning with `stable`:

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

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

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