Poetry Bazel Rule

This repository provides a rule for Poetry integration with Bazel's own rules_python. It does so by calling poetry export to generate a requirements file which can then be fed into the pip_install or pip_parse rules.

Installation

Prerequisites

• Poetry 1.2 or higher
• rules_python 0.5.0 or higher
• Bazel 3.0 or higher

Add rules_python_poetry to your WORKSPACE
