yamllint-github-action

Yamllint GitHub Actions allow you to execute yamllint command within GitHub Actions.

The output of the actions can be viewed from the Actions tab in the main repository view. If the actions are executed on a pull request event, a comment may be posted on the pull request.

Yamllint GitHub Actions is a single GitHub Action that can be executed on different directories depending on the content of the GitHub Actions YAML file.

Success Criteria

An exit code of 0 is considered a successful execution.

Usage

The most common usage is to run yamllint on a file/directory. A comment will be posted to the pull request depending on the output of the Yamllint command being executed. This workflow can be configured by adding the following content to the GitHub Actions workflow YAML file.

name: 'Yamllint GitHub Actions'
on:
  - pull_request
jobs:
  yamllint:
    name: 'Yamllint'
    runs-on: ubuntu-latest
    steps:
      - name: 'Checkout'
        uses: actions/checkout@master
      - name: 'Yamllint'
        uses: karancode/yamllint-github-action@master
        with:
          yamllint_file_or_dir: '<yaml_file_or_dir>'
          yamllint_strict: false
          yamllint_comment: true
        env:
          GITHUB_ACCESS_TOKEN: ${{ secrets.GITHUB_TOKEN }}

This was a simplified example showing the basic features of this Yamllint GitHub Actions.
