Part 5 Package and Deployment

We are almost finished with our python package series. In this post weโ€™ll discuss deployment.

  • Github repo
  • PyInstaller
  • Releases
  • PyPi

Github

There isnโ€™t much to do in terms of github or any other git server. Just push your changes and you are done. I would recommend using tags, for example for indicating a version, i.e. v2.0.1. And update your README file.

PyInstaller

Depending on how complex your package is, and if it can run as an exe or dmg, you can package your application with PyInstaller.

First install pyinstaller:

pip install pyinstaller
Enter fullscreen mode Exit fullscreen mode

Then run:

pyinstaller your_file.py
Enter fullscreen mode Exit fullscreen mode

This will generate the bundle in a subdirectory called dist.

One File:

pyinstaller your_file.py --onefile
Enter fullscreen mode Exit fullscreen mode

Debugging:

pyinstaller your_file.py --onefile --log-level LEVEL
Enter fullscreen mode Exit fullscreen mode

Amount of detail in build-time console messages. LEVEL may be one of TRACE, DEBUG, INFO, WARN, ERROR, CRITICAL (default: INFO).

For full usage visit the docs

Add it to Release

Once you have a dmg, or exe, you can add it to the releases on github, and this is nice for end users that donโ€™t know how to pip, or compile code. This is well documented.

PyPi

Docs

Build

Delete dist folder if you used pyinstaller.

Letโ€™s build the package first, ensuring you have all the tools installed.

python -m pip install --user --upgrade setuptools wheel
Enter fullscreen mode Exit fullscreen mode

Now run this command from the same directory where setup.py is located:

python3 setup.py sdist bdist_wheel
Enter fullscreen mode Exit fullscreen mode

This command should output a lot of text and once completed should generate two files in the dist directory:

dist/
  example_pkg_your_username-0.0.1-py3-none-any.whl
  example_pkg_your_username-0.0.1.tar.gz
Enter fullscreen mode Exit fullscreen mode

Twine upload to PyPi

python -m pip install --user --upgrade twine
Enter fullscreen mode Exit fullscreen mode

You can add a configuration file in your home directory, for easy uploads:

.pypirc

[distutils]
index-servers=pypi

[pypi]
repository = https://upload.pypi.org/legacy/
username = your_username
password = your_password
Enter fullscreen mode Exit fullscreen mode

With .pypirc in place you can upload with following command:

twine upload dist/*
Enter fullscreen mode Exit fullscreen mode

Lastly secure .pypirc file so only current user can read it:

chmod 600 ~/.pypirc
Enter fullscreen mode Exit fullscreen mode

A couple of things to note: I couldnโ€™t test with the test site for pypi. So I ended up just doing it to the real site. Ensure your version number in the setup.py is correct, and all the information there. Once you upload a version, you cannot reupload again unless you change the version number.

Installing your package

After a few seconds check your package in your PyPi account, if is there. Install it via pip on your local machine. And you have finally completed your first deployment.

Recap

Every release:

  • Update git repo
  • Upload git release (option)
  • Compile with setup tools
  • Upload with twine to PyPi

Congratulations for making it to the end! Any feedback is welcomed! Remember do not deploy on Fridays. :)
