Docker image for Python 3 and Flake8

This image is meant to be used to quickly check if code is alright. My use case is automated CI runs.

What's included

• Python 3.x (latest), as the image is based on python:3-alpine
• Flake8 with the following plugins (latest versions, as available on PyPI at image build time):
  • flake8-comprehensions
  • flake8-docstrings
  • flake8-import-order
  • flake8-mutable
  • flake8-pep3101
  • flake8-pyi
  • flake8-quotes
  • flake8-string-format
  • pep8-naming
• Image is configured to run as a non-privileged (non-root) user.
• Some default flake8 settings that I prefer, like double quotes and 120-column margins. YMMV, override those in your own .flake file.

Usage

Image is pre-configured to have flake8 as its entryppoint and starts in /project (empty, bind-mount your code in there).

So, assuming your code is world-readable, to lint your files, all you have to run is:

docker -it --rm -v $(pwd):/project drdaeman/flake8
