This repository is for the GitHub Action to run a Super-Linter.
It is a simple combination on various linters, written in bash
, to help validate your source code.
The end goal of this tool:
- Prevent broken code from being uploaded to master branches
- Help establish coding best practices across multiple languages
- Build guidelines for code layout and format
- Automate the process to help streamline code reviews
The super-linter finds issues and reports them to the console output. Fixes are suggested in the console output but not automatically fixed, and a status check will show up as failed on the pull request.
Developers on GitHub can call the GitHub Action to lint their code base with the following list of linters:
Language | Linter |
---|---|
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 |
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
- Check out the Wiki for customization options
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:

env:
VALIDATE_ALL_CODEBASE: false
VALIDATE_ANSIBLE: false
...
The super-linter allows you to pass the following ENV
variables to be able to trigger different functionality.
Note: All the VALIDATE_[LANGAUGE]
variables behave in a specific way.
If none of them are passed, then they all default to true.
However if any one of the variables are set, we default to leaving any unset variable to false.
This means that if you run the linter "out of the box", all langauges will be checked.
But if you wish to select specific linters, we give you full control to choose which linters are run,
and won't run anything unexpected.
ENV VAR | Default Value | Notes |
---|---|---|
VALIDATE_ALL_CODEBASE | true |
Will parse the entire repository and find all files to validate across all types. NOTE: When set to false , only new or edited files will be parsed for validation. |

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
- If your repository does not have rules files, they will fall back to defaults in this repositories
If you need to disable certain rules and functionality, you can view Disable Rules
The Docker container that is built from this repository is located at https://cloud.docker.com/u/admiralawkbar/repository/docker/admiralawkbar/super-linter
If you find that you need to run super-linter locally, you can follow the documentation at Running super-linter locally
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
Below are a list of the known limitations for the Github Super-Linter:
- Due to being completely packaged at run time, you will not be able to update dependencies or change versions of the enclosed linters and binaries
- Reading additional details from
package.json
are not read by the Github Super-Linter - Downloading additional codebases as dependencies from private repositories will fail due to lack of permissions
