# Run Super-Linter locally to test your branch of code

If you want to test locally against the **Super-Linter** to test your branch of code, you will need to complete the following:

- Clone your testing source code to your local environment
- Install Docker to your local environment
- Pull the container down
- Run the container
- Debug/Troubleshoot

## Install Docker to your local machine

You can follow the link below on how to install and configure **Docker** on your local machine

- [Docker Install Documentation](https://docs.docker.com/install/)

## Download the latest Super-Linter Docker container

- Pull the latest **Docker** container down from **DockerHub**
  - `docker pull github/super-linter:latest`
    Once the container has been downloaded to your local environment, you can then begin the process, or running the container against your codebase.

## Run the container Locally

- You can run the container locally with the following **Base** flags to run your code:
  - `docker run -e RUN_LOCAL=true -v /path/to/local/codebase:/tmp/lint github/super-linter`
    - To run against a single file you can use: `docker run -e RUN_LOCAL=true -v /path/to/local/codebase/file:/tmp/lint/file github/super-linter`
  - **NOTE:** You need to pass the `RUN_LOCAL` flag to bypass some of the GitHub Actions checks, as well as the mapping of your local codebase to `/tmp/lint` so that the linter can pick up the code
  - **NOTE:** If you want to override the `/tmp/lint` folder, you can set the `DEFAULT_WORKSPACE` environment variable to point to the folder you'd prefer to scan.
  - **NOTE:** The flag:`RUN_LOCAL` will set: `VALIDATE_ALL_CODEBASE` to true. This means it will scan **all** the files in the directory you have mapped. If you want to only validate a subset of your codebase, map a folder with only the files you wish to have linted

### Flags for running Locally

You can add as many **Additional** flags as needed, documented in [README.md](../README.md#Environment-variables)

## Troubleshooting

### Run container and gain access to the command line

If you need to run the container locally and gain access to its command line, you can run the following command:

- `docker run -it --entrypoint /bin/bash github/super-linter`
- This will drop you in the command line of the docker container for any testing or troubleshooting that may be needed.
