# Won't be installing `poetry` into the image to reduce image size, instead `requirements.txt` will be used.
# Update requirements.txt manually with:
#       poetry export -f requirements.txt --output requirements.txt --without dev --without-hashes
# Or setup a pre-commit hook:
#       https://python-poetry.org/docs/pre-commit-hooks/#poetry-export
