**NOTICE**: If your use of the super-linter action failed around April 26th, 2023, we changed the organization name from `github` to `super-linter` so you will need to update your references to this action from `github/super-linter` to `super-linter/super-linter`.
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.
The design of the **Super-Linter** is currently to allow linting to occur in **GitHub Actions** as a part of continuous integration occurring on pull requests as the commits get pushed. It works best when commits are being pushed early and often to a branch with an open or draft pull request. There is some desire to move this closer to local development for faster feedback on linting errors but this is not yet supported.
**NOTE:** If you pass the _Environment_ variable `GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}` in your workflow, then the **GitHub Super-Linter** will mark the status of each individual linter run in the Checks section of a pull request. Without this you will only see the overall status of the full run. There is no need to set the **GitHub** Secret as it is automatically set by GitHub, it only needs to be passed to the action.
| **ANSIBLE_DIRECTORY** | `/ansible` | Flag to set the root directory for Ansible file location(s), relative to `DEFAULT_WORKSPACE`. Set to `.` to use the top-level of the `DEFAULT_WORKSPACE`. |
| **BASH_SEVERITY** | `style` | Specify the minimum severity of errors to consider in shellcheck. Valid values in order of severity are error, warning, info and style. |
| **EDITORCONFIG_FILE_NAME** | `.ecrc` | Filename for [editorconfig-checker configuration](https://github.com/editorconfig-checker/editorconfig-checker) |
| **ERROR_ON_MISSING_EXEC_BIT** | `false` | If set to `false`, the `bash-exec` linter will report a warning if a shell script is not executable. If set to `true`, the `bash-exec` linter will report an error instead. |
| **FILTER_REGEX_EXCLUDE** | `none` | Regular expression defining which files will be excluded from linting (ex: `.*src/test.*`) |
| **FILTER_REGEX_INCLUDE** | `all` | Regular expression defining which files will be processed by linters (ex: `.*src/.*`) |
| **GITHUB_CUSTOM_API_URL** | `https://api.github.com` | Specify a custom GitHub API URL in case GitHub Enterprise is used: e.g. `https://github.myenterprise.com/api/v3` |
| **GITHUB_DOMAIN** | `github.com` | Specify a custom GitHub domain in case GitHub Enterprise is used: e.g. `github.myenterprise.com` |
| **IGNORE_GENERATED_FILES** | `false` | If set to `true`, super-linter will ignore all the files with `@generated` marker but without `@not-generated` marker. |
| **IGNORE_GITIGNORED_FILES** | `false` | If set to `true`, super-linter will ignore all the files that are ignored by Git. |
| **KUBERNETES_KUBECONFORM_OPTIONS** | `null` | Additional arguments to pass to the command-line when running **Kubernetes Kubeconform** (Example: --ignore-missing-schemas) |
| **LINTER_RULES_PATH** | `.github/linters` | Directory for all linter configuration rules. |
| **LOG_FILE** | `super-linter.log` | The filename for outputting logs. All output is sent to the log file regardless of `LOG_LEVEL`. |
| **LOG_LEVEL** | `VERBOSE` | How much output the script will generate to the console. One of `ERROR`, `WARN`, `NOTICE`, `VERBOSE`, `DEBUG` or `TRACE`. |
| **SSL_CERT_SECRET** | `none` | SSL cert to add to the **Super-Linter** trust store. This is needed for users on `self-hosted` runners or need to inject the cert for security standards (ex. ${{ secrets.SSL_CERT }}) |
| **SSH_KEY** | `none` | SSH key that has access to your private repositories |
| **SSH_SETUP_GITHUB** | `false` | If set to `true`, adds the `github.com` SSH key to `known_hosts`. This is ignored if `SSH_KEY` is provided - i.e. the `github.com` SSH key is always added if `SSH_KEY` is provided |
| **SSH_INSECURE_NO_VERIFY_GITHUB_KEY** | `false` | **INSECURE -** If set to `true`, does not verify the fingerprint of the github.com SSH key before adding this. This is not recommended! |
| **SUPPRESS_FILE_TYPE_WARN** | `false` | If set to `true`, will hide warning messages about files without their proper extensions. Default is `false` |
| **SUPPRESS_POSSUM** | `false` | If set to `true`, will hide the ASCII possum at top of log output. Default is `false` |
| **TYPESCRIPT_STANDARD_TSCONFIG_FILE** | `tsconfig.json` | Filename for [TypeScript configuration](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html) in [ts-standard](https://github.com/standard/ts-standard) (ex: `tsconfig.json`, `tsconfig.eslint.json`) |
| **USE_FIND_ALGORITHM** | `false` | By default, we use `git diff` to find all files in the workspace and what has been updated, this would enable the Linux `find` method instead to find all files to lint |
| **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 codebase. 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 the `.github/linters/` directory of your repository, and modify them to suit your needs.
- The rules files in [this repository's `TEMPLATE` folder](https://github.com/super-linter/super-linter/tree/main/TEMPLATES) will be used as defaults should any be omitted.
If your repository contains your own rules files that live outside of a `.github/linters/` directory, you will have to tell Super-Linter where your rules files are located in your repository, and what their filenames are. To learn more, see [Using your own rules files](docs/using-rules-files.md).
If you need to disable certain _rules_ and _functionality_, you can view [Disable Rules](https://github.com/super-linter/super-linter/blob/main/docs/disabling-linters.md)
If you need to lint only a folder or exclude some files from linting, you can use optional environment parameters `FILTER_REGEX_INCLUDE` and `FILTER_REGEX_EXCLUDE`
If you find that you need to run super-linter locally, you can follow the documentation at [Running super-linter locally](https://github.com/super-linter/super-linter/blob/main/docs/run-linter-locally.md)
Check out the [note](#how-it-works) in **How it Works** to understand more about the **Super-Linter** linting locally versus via continuous integration.
Check out this [snippet](https://gitlab.com/snippets/1988376) and this Guided Exploration: [GitLab CI CD Extension for Super-Linter](https://gitlab.com/guided-explorations/ci-cd-plugin-extensions/ci-cd-plugin-extension-github-action-super-linter)
You can checkout this repository using [GitHub Codespaces](https://github.com/features/codespaces/) and [Container Remote Development](https://code.visualstudio.com/docs/remote/containers), and debug the linter using the `Test Linter` task.
If you need to inject a SSL cert into the trust store, you will need to first copy the cert to **GitHub Secrets**
Once you have copied the plain text certificate into **GitHub Secrets**, you can use the variable `SSL_CERT_SECRET` to point the **Super-Linter** to the files contents.
Once found, it will load the certificate contents to a file, and to the trust store.
