PyPI packages in the Package Registry

Introduced in GitLab Premium 12.10.

Moved to GitLab Core in 13.3.

Publish PyPI packages in your project’s Package Registry. Then install the packages whenever you need to use them as a dependency.

The Package Registry works with:

pip
twine

Build a PyPI package

This section explains how to create a PyPI package.

If you already use PyPI and know how to build your own packages, go to the next section.

Install pip and twine

Install a recent version of pip and twine.

Create a project

Create a test project.

Open your terminal.
Create a directory called MyPyPiPackage, and then go to that directory:
```
mkdir MyPyPiPackage && cd MyPyPiPackage
```
Create another directory and go to it:
```
mkdir mypypipackage && cd mypypipackage
```
Create the required files in this directory:
```
touch __init__.py
touch greet.py
```

Open the greet.py file, and then add:

def SayHello():
    print("Hello from MyPyPiPackage")
    return

Open the __init__.py file, and then add:
```
from .greet import SayHello
```
To test the code, in your MyPyPiPackage directory, start the Python prompt.
```
python
```

Run this command:

>>> from mypypipackage import SayHello
>>> SayHello()

A message indicates that the project was set up successfully:

Python 3.8.2 (v3.8.2:7b3ab5921f, Feb 24 2020, 17:52:18)
[Clang 6.0 (clang-600.0.57)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from mypypipackage import SayHello
>>> SayHello()
Hello from MyPyPiPackage

Create a package

After you create a project, you can create a package.

In your terminal, go to the MyPyPiPackage directory.
Create a setup.py file:
```
touch setup.py
```
This file contains all the information about the package. For more information about this file, see creating setup.py. Because GitLab identifies packages based on Python normalized names (PEP-503), ensure your package name meets these requirements. See the installation section for details.

Open the setup.py file, and then add basic information:

import setuptools

setuptools.setup(
    name="mypypipackage",
    version="0.0.1",
    author="Example Author",
    author_email="author@example.com",
    description="A small example package",
    packages=setuptools.find_packages(),
    classifiers=[
        "Programming Language :: Python :: 3",
        "License :: OSI Approved :: MIT License",
        "Operating System :: OS Independent",
    ],
    python_requires='>=3.6',
)

Save the file.
Execute the setup:
```
python3 setup.py sdist bdist_wheel
```

The output should be visible in a newly-created dist folder:

ls dist

The output should appear similar to the following:

mypypipackage-0.0.1-py3-none-any.whl mypypipackage-0.0.1.tar.gz

The package is now ready to be published to the Package Registry.

Authenticate with the Package Registry

Before you can publish to the Package Registry, you must authenticate.

To do this, you can use:

A personal access token with the scope set to api.
A deploy token with the scope set to read_package_registry, write_package_registry, or both.
A CI job token.

Authenticate with a personal access token

To authenticate with a personal access token, edit the ~/.pypirc file and add:

[distutils]
index-servers =
    gitlab

[gitlab]
repository = https://gitlab.example.com/api/v4/projects/<project_id>/packages/pypi
username = __token__
password = <your personal access token>

username must be __token__ exactly.
Your project ID is on your project's home page.

Authenticate with a deploy token

To authenticate with a deploy token, edit your ~/.pypirc file and add:

[distutils]
index-servers =
    gitlab

[gitlab]
repository = https://gitlab.example.com/api/v4/projects/<project_id>/packages/pypi
username = <deploy token username>
password = <deploy token>

Your project ID is on your project's home page.

Authenticate with a CI job token

Introduced in GitLab 13.4.

To work with PyPI commands within GitLab CI/CD, you can use CI_JOB_TOKEN instead of a personal access token or deploy token.

For example:

image: python:latest

run:
  script:
    - pip install twine
    - python setup.py sdist bdist_wheel
    - TWINE_PASSWORD=${CI_JOB_TOKEN} TWINE_USERNAME=gitlab-ci-token python -m twine upload --repository-url https://gitlab.example.com/api/v4/projects/${CI_PROJECT_ID}/packages/pypi dist/*

You can also use CI_JOB_TOKEN in a ~/.pypirc file that you check in to GitLab:

[distutils]
index-servers =
    gitlab

[gitlab]
repository = https://gitlab.example.com/api/v4/projects/${env.CI_PROJECT_ID}/packages/pypi
username = gitlab-ci-token
password = ${env.CI_JOB_TOKEN}

Publish a PyPI package

When publishing packages, note that:

The maximum allowed size is 50 MB.
You can't upload the same version of a package multiple times. If you try, you receive the error Validation failed: File name has already been taken.

Ensure your version string is valid

If your version string (for example, 0.0.1) isn't valid, it gets rejected. GitLab uses the following regex to validate the version string.

\A(?:
    v?
    (?:([0-9]+)!)?                                                 (?# epoch)
    ([0-9]+(?:\.[0-9]+)*)                                          (?# release segment)
    ([-_\.]?((a|b|c|rc|alpha|beta|pre|preview))[-_\.]?([0-9]+)?)?  (?# pre-release)
    ((?:-([0-9]+))|(?:[-_\.]?(post|rev|r)[-_\.]?([0-9]+)?))?       (?# post release)
    ([-_\.]?(dev)[-_\.]?([0-9]+)?)?                                (?# dev release)
    (?:\+([a-z0-9]+(?:[-_\.][a-z0-9]+)*))?                         (?# local version)
)\z}xi

You can experiment with the regex and try your version strings by using this regular expression editor.

For more details about the regex, review this documentation.

Publish a PyPI package by using twine

To publish a PyPI package, run a command like:

python3 -m twine upload --repository gitlab dist/*

This message indicates that the package was published successfully:

Uploading distributions to https://gitlab.example.com/api/v4/projects/<your_project_id>/packages/pypi
Uploading mypypipackage-0.0.1-py3-none-any.whl

To view the published package, go to your project's Packages & Registries page.

If you didn't use a .pypirc file to define your repository source, you can publish to the repository with the authentication inline:

TWINE_PASSWORD=<personal_access_token or deploy_token> TWINE_USERNAME=<username or deploy_token_username> python3 -m twine upload --repository-url https://gitlab.example.com/api/v4/projects/<project_id>/packages/pypi dist/*

If you didn't follow the steps on this page, ensure your package was properly built, and that you created a PyPI package with setuptools.

You can then upload your package by using the following command:

python -m twine upload --repository <source_name> dist/<package_file>

<package_file> is your package filename, ending in .tar.gz or .whl.
<source_name> is the source name used during setup.

Install a PyPI package

To install the latest version of a package, use the following command:

pip install --extra-index-url https://__token__:<personal_access_token>@gitlab.example.com/api/v4/projects/<project_id>/packages/pypi/simple --no-deps <package_name>

<package_name> is the package name.
<personal_access_token> is a personal access token with the read_api scope.
<project_id> is the project ID.

If you were following the guide and want to install the MyPyPiPackage package, you can run:

pip install mypypipackage --no-deps --extra-index-url https://__token__:<personal_access_token>@gitlab.example.com/api/v4/projects/<your_project_id>/packages/pypi/simple

This message indicates that the package was installed successfully:

Package names

GitLab looks for packages that use Python normalized names (PEP-503). The characters -, _, and . are all treated the same, and repeated characters are removed.

A pip install request for my.package looks for packages that match any of the three characters, such as my-package, my_package, and my....package.
