This is a preconfigured Docker image with commitlint. It has the following settings

• Extend @commitlint/config-conventional
• Disable the scope-case rule to allow any case
• Custom imperative-tense rule to check subjects for imperative mood

This image can be used in three ways.

1. As a standalone commitlint CLI
2. As a pre-commit hook
3. As a GitHub action

$ docker pull extenda/commitlint
$ echo "feat: add feature" | docker run --rm -i extenda/commitlint
$ docker run --rm -i extenda/commitlint --from HEAD~1

The image can be used to build a pre-commit hook. Extenda provides a commitlint pre-commit hook that can be configured like this:

- repo: [email protected]:extenda/pre-commit-hooks.git
  rev: v0.4
  hooks:
    - id: commitlint
      stages: [commit-msg]

To support GitHub actions, the docker image offers an alternative entrypoint under /usr/local/bin/action.

Usage: action [-c <sha>] [-m <message>]

Extenda Retail provides a GitHub action out-of-the-box available at https://github.com/extenda/actions/commitlint.
