How to publish a Python package¶
This page assumes that you are working with an existing Python package which has been configured for auto-publishing via our common pipeline. See how to add the common pipeline to a Python package if this has not been done.
If you want to learn more about how we structure Python packages, follow our Python package tutorial.
Python packages which make use of our common pipeline are set up to auto-publish packages when a new git tag is pushed.
Increment the version number¶
When making a new release, the version number defined in
setup.py needs to be incremented. This may have already been done by Merge
Requests adding new features.
If you need to increment the version number, follow the semantic versioning guidelines.
Update the changelog¶
Packages should have a
CHANGELOG.md file in the root of the repository
providing a summary of changes over time. If you have increased the version,
make sure that the changelog is up to date.
Tag the release¶
master branch commit with your version number. For example,
if you are releasing version 1.2.3:
git tag 1.2.3
Tag names must match the version number set in the
Push tags to the repository:
git push origin --tags
Check the release progress¶
A CI pipeline will be created to build and publish the package. The pipeline
checks that the version number in your
matches the tag name.
An example pipeline from the FastAPI pagination library is show below. This pipeline publishes to PyPI and the GitLab package registry. Before a package is published to the public PyPI registry, it is pushed to the test registry.
In this how-to you learned how to tag and publish a new release of a Python project.
