Bazel Python Package Example
This repository is an example Buildkite pipeline that builds, tests, and packages a Python library using Bazel.
See the full Getting Started Guide for step-by-step instructions on how to get this running.
he Python package is built, tested, and uploaded as a Buildkite artifact using Bazel
How it works
This example uses Bazel to build and test a Python package and then use that package in another Python program configured with a third-party dependency. The repo is also configured with a Buildkite pipeline that uploads the Bazel-built Python package as a Buildkite build artifact.
