Black Docker image#
Official Black Docker images are available on Docker Hub.
Black images with the following tags are available:
release numbers, e.g.
21.5b2,21.6b0,21.7b0etc.
ℹ Recommended for users who want to use a particular version of Black.latest_release- tag created when a new version of Black is released.
ℹ Recommended for users who want to use released versions of Black. It maps to the latest release of Black.latest- tag used for the newest image of Black.
ℹ Recommended for users who always want to use the latest version of Black, even before it is released.
There is one more tag used for Black Docker images - latest_non_release. It is
created for all unreleased
commits on the main branch. This tag is
not meant to be used by external users.
Usage#
A permanent container doesn’t have to be created to use Black as a Docker image. It’s
enough to run Black commands for the chosen image denoted as :tag. In the below
examples, the latest_release tag is used. If :tag is omitted, the latest tag will
be used.
More about Black usage can be found in Usage and Configuration: The basics.
Check Black version#
$ docker run --rm pyfound/black:latest_release black --version
Check code#
$ docker run --rm --volume $(pwd):/src --workdir /src pyfound/black:latest_release black --check .
Remark: besides regular Black exit codes returned by --check
option, Docker exit codes
should also be considered.
