Super Linter Reusable Workflow Examples

The GitHub Super-Linter project is a fantastic way to lint all your file types with a single GitHub Actions Workflow. A great way to implement it everywhere is to use GHA's Reusable Workflows (see below).

My video walkthrough of this repository

Features of this custom Super-Linter example

• All the features of Super-Linter in a Reusable Workflow
• Bonus: Optionally turn off non-DevOps linters (CSS, JS, HTML, etc.) when you want to ignore code (in my case it's to ignore sample code I stick in DevOps projects)
• Bonus: I added Job steps to correctly determine which branch to diff files with (in the case of having multiple release branches)
• Bonus: Lints only changed files on a PR, but lints all files on merge to main (or any release) branch

How to reuse this example as a Reusable Workflow

1. Fork this repository for you to customize your linters
2. Add a workflow to all your other repositories that calls your linter workflow using GitHub's "Reusable Workflow"
3. Add something similar to this to those workflows:

---
name: Lint Code Base

on:
  
  push:
    branches: [main]
  
  pull_request:

jobs:
  call-super-linter:

    name: Call Super-Linter

    # use Reusable Workflows to call my linter config remotely
    # https://docs.github.com/en/actions/learn-github-actions/reusing-workflows
    
    permissions:
      contents: read # clone the repo to lint
      statuses: write #read/write to repo custom statuses

    #FIXME: customize uri to point to your forked linter repository
    uses: bretfisher/super-linter-workflow/.github/workflows/super-linter.yaml@main
    
    # Optional settings examples
    
    # with:
    
      # devops-only: false
      
      # filter-regex-exclude: html/.*

How to run Super-Linter locally

Option 1: Use nektos/act to run an existing GitHub Action workflow on your local repository clone.

Option 2: Use Docker to run the Super-Linter image directly.
