GitLab PyPi Repository (PREMIUM)

Introduced in GitLab Premium 12.10.

With the GitLab PyPi Repository, every project can have its own space to store PyPi packages.

The GitLab PyPi Repository works with:

pip
twine

Setting up your development environment

You will need a recent version of pip and twine.

Enabling the PyPi Repository

NOTE: Note: This option is available only if your GitLab administrator has enabled support for the Package Registry. (PREMIUM ONLY)

After the PyPi Repository is enabled, it will be available for all new projects by default. To enable it for existing projects, or if you want to disable it:

Navigate to your project's Settings > General > Permissions.
Find the Packages feature and enable or disable it.
Click on Save changes for the changes to take effect.

You should then be able to see the Packages & Registries section on the left sidebar.

Getting started

This section will cover creating a new example PyPi package to upload. This is a quickstart to test out the GitLab PyPi Registry. If you already understand how to build and publish your own packages, move on to the next section.

Create a project

Understanding how to create a full Python project is outside the scope of this guide, but you can create a small package to test out the registry. Start by creating a new directory called MyPyPiPackage:

mkdir MyPyPiPackage && cd MyPyPiPackage

After creating this, create another directory inside:

mkdir mypypipackage && cd mypypipackage

Create two new files inside this directory to set up the basic project:

touch __init__.py
touch greet.py

Inside greet.py, add the following code:

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

Inside the __init__.py file, add the following:

from .greet import SayHello

Now that the basics of our project is completed, we can test that the code runs. Start the Python prompt inside your top MyPyPiPackage directory. Then run:

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

You should see an output similar to the following:

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

Once we've verified that the sample project is working as above, we can next work on creating a package.

Create a package

Inside your MyPyPiPackage directory, we need to create a setup.py file. Run the following:

touch setup.py

This file contains all the information about our package. For more information about this file, see creating setup.py. For this guide, we don't need to extensively fill out this file, simply add the below to your setup.py:

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, then execute the setup like so:

python3 setup.py sdist bdist_wheel

If successful, you should be able to see the output in a newly created dist folder. Run:

ls dist

And confirm your output matches the below:

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

Our package is now all set up and ready to be uploaded to the GitLab PyPi Package Registry. Before we do so, we next need to set up authentication.

Adding the GitLab PyPi Repository as a source

Authenticating with a personal access token

You will need the following:

A personal access token. You can generate a personal access token with the scope set to api for repository authentication.
A suitable name for your source.
Your project ID which can be found on the home page of your project.

Edit your ~/.pypirc file and add the following:

[distutils]
index-servers =
    gitlab

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

Authenticating with a deploy token

You will need the following:

A deploy token. You can generate a deploy token with the read_package_registry and/or write_package_registry scopes for repository authentication.
A suitable name for your source.
Your project ID which can be found on the home page of your project.

Edit your ~/.pypirc file and add the following:

[distutils]
index-servers =
    gitlab

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

Uploading packages

When uploading packages, note that:

The maximum allowed size is 50 Megabytes.
If you upload the same package with the same version multiple times, each consecutive upload is saved as a separate file. When installing a package, GitLab will serve the most recent file.

Upload packages with Twine

If you were following the guide above, then the MyPyPiPackage package should be ready to be uploaded. Run the following command:

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

If successful, you should see the following:

Uploading distributions to https://gitlab.com/api/v4/projects/<your_project_id>/packages/pypi
Uploading mypypipackage-0.0.1-py3-none-any.whl
100%|███████████████████████████████████████████████████████████████████████████████████████████| 4.58k/4.58k [00:00<00:00, 10.9kB/s]
Uploading mypypipackage-0.0.1.tar.gz
100%|███████████████████████████████████████████████████████████████████████████████████████████| 4.24k/4.24k [00:00<00:00, 11.0kB/s]

This indicates that the package was uploaded successfully. You can then navigate to your project's Packages & Registries page and see the uploaded packages.

If you did not follow the guide above, the you'll need to ensure your package has been properly built and you created a PyPi package with setuptools.

You can then upload your package using the following command:

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

Where:

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

Install packages

Install the latest version of a package using the following command:

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