Super-Linter

This repository is for the GitHub Action to run a Super-Linter.
Developers on GitHub can call this Action to lint their code base with the following list of linters:

• Ruby (Rubocop)
• Shell (Shellcheck)
• Ansible (Ansible-lint)
• YAML (Yamllint)
• Python3 (Pylint)
• JSON (JsonLint)
• MarkDown (Markdownlint)
• Perl (Perl)
• XML (LibXML)
• Coffeescript (coffeelint)
• Javascript (eslint)(standard)
• Typescript (eslint)(standard)
• Golang (golangci-lint)
• Dockerfile (dockerfilelint)
• Terraform (tflint)

How to use

To use this GitHub Action you will need to complete the following:

• Add the GitHub Action: Super-Linter to your current GitHub Actions workflow
• Enjoy your more stable, and cleaner code base

Example connecting GitHub Action Workflow

In your repository you should have a .github/workflows folder with GitHub Action similar to below:

• .github/workflows/linter.yml

This file should have the following code:

Template rules files

You can use the GitHub Super-Linter with or without your own personal rules sets. This allows for greater flexibility for each individual code base. The Template rules all try to follow the standards we believe should be enabled at the basic level.

• Copy any or all template rules files from TEMPLATES/ into your repository in the location: .github/linters/ of your repository
  • If your repository does not have rules files, they will fall back to defaults in this repositories TEMPLATE folder

Docker Hub

The Docker container that is built from this repository is located at https://cloud.docker.com/u/admiralawkbar/repository/docker/admiralawkbar/super-linter

Running Super-Linter locally (troubleshooting/debugging/enhancements)

If you find that you need to run super-linter locally, you can follow the documentation at Running super-linter locally

CI/CT/CD

The Super-Linter has CI/CT/CD configured utilizing GitHub Actions.

• When a branch is created and code is pushed, a GitHub Action is triggered for building the new Docker container with the new codebase
• The Docker container is then ran against the test cases to validate all code sanity
  • .automation/test contains all test cases for each language that should be validated
• These GitHub Actions utilize the Checks API and Protected Branches to help follow the SDLC
• When the Pull Request is merged to master, the Super-Linter Docker container is then updated and deployed with the new codebase
  • Note: The branches Docker container is also removed from DockerHub to cleanup after itself
