Publish generic files, like release binaries, in your project's Package Registry. Then, install the packages whenever you need to use them as a dependency.

## Authenticate to the Package Registry

To authenticate to the Package Registry, you need either a [personal access token](../../../api/index.md#personalprojectgroup-access-tokens),
[CI/CD job token](../../../ci/jobs/ci_job_token.md), or [deploy token](../../project/deploy_tokens/index.md).

In addition to the standard API authentication mechanisms, the generic package
API allows authentication with HTTP Basic authentication for use with tools that
do not support the other available mechanisms. The `user-id` is not checked and
may be any value, and the `password` must be either a [personal access token](../../../api/index.md#personalprojectgroup-access-tokens),
a [CI/CD job token](../../../ci/jobs/ci_job_token.md), or a [deploy token](../../project/deploy_tokens/index.md).

## Publish a package file

When you publish a package file, if the package does not exist, it is created.

Prerequisites:

- You must [authenticate with the API](../../../api/index.md#authentication).
  If authenticating with a deploy token, it must be configured with the `write_package_registry`
  scope. If authenticating with a personal access token or project access token, it must be
  configured with the `api` scope.

```plaintext
PUT /projects/:id/packages/generic/:package_name/:package_version/:file_name?status=:status
```

| Attribute          | Type            | Required | Description                                                                                                                      |
| -------------------| --------------- | ---------| -------------------------------------------------------------------------------------------------------------------------------- |
| `id`               | integer/string  | yes      | The ID or [URL-encoded path of the project](../../../api/index.md#namespaced-path-encoding).                                              |
| `package_name`     | string          | yes      | The package name. It can contain only lowercase letters (`a-z`), uppercase letter (`A-Z`), numbers (`0-9`), dots (`.`), hyphens (`-`), or underscores (`_`).
| `package_version`  | string          | yes      | The package version. The following regex validates this: `\A(\.?[\w\+-]+\.?)+\z`. You can test your version strings on [Rubular](https://rubular.com/r/aNCV0wG5K14uq8).
| `file_name`        | string          | yes      | The filename. It can contain only lowercase letters (`a-z`), uppercase letter (`A-Z`), numbers (`0-9`), dots (`.`), hyphens (`-`), or underscores (`_`).
| `status`           | string          | no       | The package status. It can be `default` (default) or `hidden`. Hidden packages do not appear in the UI or [package API list endpoints](../../../api/packages.md).
| `select`           | string          | no       | The response payload. By default, the response is empty. Valid values are: `package_file`. `package_file` returns details of the package file record created by this request.

Provide the file context in the request body.

Example request using a personal access token:

```shell
curl --header "PRIVATE-TOKEN: <your_access_token>" \
     --upload-file path/to/file.txt \
     "https://gitlab.example.com/api/v4/projects/24/packages/generic/my_package/0.0.1/file.txt?status=hidden"
```

Example response without attribute `select`:

```json
{
  "message":"201 Created"
}
```

Example response with attribute `select = package_file`:

```json
{
  "id": 1,
  "package_id": 1,
  "created_at": "2021-10-12T12:05:23.387Z",
  "updated_at": "2021-10-12T12:05:23.387Z",

```

### Publishing a package with the same name or version

When you publish a package with the same name and version as an existing package, the new package
files are added to the existing package. You can still use the UI or API to access and view the
existing package's older files. To delete these older package revisions, consider using the Packages
API or the UI.

#### Do not allow duplicate Generic packages

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/293755) in GitLab 13.12.

To prevent users from publishing duplicate generic packages, you can use the [GraphQl API](../../../api/graphql/reference/index.md#packagesettings)
or the UI.

In the UI:

1. For your group, go to **Settings > Packages & Registries**.
1. Expand the **Package Registry** section.
1. Turn on the **Reject duplicates** toggle.
1. Optional. To allow some duplicate packages, in the **Exceptions** box enter a regex pattern that
   matches the names and/or versions of packages to allow.

Your changes are automatically saved.

## Download package file

Download a package file.

If multiple packages have the same name, version, and filename, then the most recent one is retrieved.

Prerequisites:

- You need to [authenticate with the API](../../../api/index.md#authentication). If authenticating with a deploy token, it must be configured with the `read_package_registry` and/or `write_package_registry` scope.

```plaintext
GET /projects/:id/packages/generic/:package_name/:package_version/:file_name
```

| Attribute          | Type            | Required | Description                                                                         |
| -------------------| --------------- | ---------| ------------------------------------------------------------------------------------|
| `id`               | integer/string  | yes      | The ID or [URL-encoded path of the project](../../../api/index.md#namespaced-path-encoding). |
| `package_name`     | string          | yes      | The package name.                                                                   |
| `package_version`  | string          | yes      | The package version.                                                                |
| `file_name`        | string          | yes      | The filename.                                                                      |

The file context is served in the response body. The response content type is `application/octet-stream`.

Example request that uses a personal access token:

```shell
curl --header "PRIVATE-TOKEN: <your_access_token>" \
     "https://gitlab.example.com/api/v4/projects/24/packages/generic/my_package/0.0.1/file.txt"
```

Example request that uses HTTP Basic authentication:

```shell
curl --user "user:<your_access_token>" \
     "https://gitlab.example.com/api/v4/projects/24/packages/generic/my_package/0.0.1/file.txt"
```

## Publish a generic package by using CI/CD

To work with generic packages in [GitLab CI/CD](../../../ci/index.md), you can use
`CI_JOB_TOKEN` in place of the personal access token in your commands.

For example:

```yaml
image: curlimages/curl:latest

stages:
  - upload
  - download

upload:
  stage: upload
  script:
    - 'curl --header "JOB-TOKEN: $CI_JOB_TOKEN" --upload-file path/to/file.txt "${CI_API_V4_URL}/projects/${CI_PROJECT_ID}/packages/generic/my_package/0.0.1/file.txt"'

download:
  stage: download
  script:
    - 'wget --header="JOB-TOKEN: $CI_JOB_TOKEN" ${CI_API_V4_URL}/projects/${CI_PROJECT_ID}/packages/generic/my_package/0.0.1/file.txt'
```

When using a Windows runner with PowerShell, you must use `Invoke-WebRequest` or `Invoke-RestMethod`
instead of `curl` in the `upload` and `download` stages.

For example:

```yaml
upload:
  stage: upload
  script:
    - Invoke-RestMethod -Headers @{ "JOB-TOKEN"="$CI_JOB_TOKEN" } -InFile path/to/file.txt -uri "${CI_API_V4_URL}/projects/${CI_PROJECT_ID}/packages/generic/my_package/0.0.1/file.txt" -Method put
```

### Enable or disable generic packages in the Package Registry

Support for generic packages is under development but ready for production use.
It is deployed behind a feature flag that is **enabled by default**.
[GitLab administrators with access to the GitLab Rails console](../../../administration/feature_flags.md)
can opt to disable it.

To enable it:

```ruby
# For the instance
Feature.enable(:generic_packages)
# For a single project
Feature.enable(:generic_packages, Project.find(<project id>))
```

To disable it:

```ruby
# For the instance
Feature.disable(:generic_packages)
# For a single project
Feature.disable(:generic_packages, Project.find(<project id>))
```

### Generic package sample project

The [Write CI-CD Variables in Pipeline](https://gitlab.com/guided-explorations/cfg-data/write-ci-cd-variables-in-pipeline) project contains a working example you can use to create, upload, and download generic packages in GitLab CI/CD.

It also demonstrates how to manage a semantic version for the generic package: storing it in a CI/CD variable, retrieving it, incrementing it, and writing it back to the CI/CD variable when tests for the download work correctly.
