Poetry is an open-source tool for managing and packaging dependencies for Python projects. It maintains a clean view of your dependency tree, streamlines the installation and management of dependencies, and simplifies packaging and distribution to PyPI. This guide installs Poetry with Pipx on Ubuntu 24.04, creates a virtual environment, and runs a Flask application using Poetry and Gunicorn. By the end, you'll have a Flask app managed entirely through Poetry, tested with Pytest, and served in production mode with Gunicorn.

Prerequisites

Have access to an Ubuntu 24.04 server.
