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

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

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.
