fmariluis/black repository overview

https://github.com/fmariluis/docker-python-black⁠

(Repo forked from https://github.com/mccutchen/docker-python-black⁠ to provide multi arch images)

A minimal multiarch Docker image for running Python's black⁠ code formatter, useful in CI pipelines or other situations where avoiding local Python/virtualenv/etc installation is ideal.

⁠Usage

An example CI step that will exit non-zero if any source code under the current directory needs to be formatted:

docker run --rm -v $(pwd):/src fmariluis/black --check --diff /src

⁠Prior Art

There are at least a handful of existing, public docker images that serve the same purpose as this one, but I wanted an image that a) explicitly tracked black releases and b) published its Dockerfile.

Here are some other public images to consider:

• kiwicom/black⁠ (lots of downloads, tracks black releases, but no public dockerfile)
• cytopia/black⁠ (many downloads, public dockerfile, but does not track black releases)
• houzefaabba/python3-black⁠ (fewer downloads, public dockerfile, tracks black releases, but outdated)
