Laravel-Based Community CTF Platform

BeeCTF

Laravel-Based Community CTF Platform.

Introduction

BeeCTF is a CTF platform intended for small and local community groups who want to host their own CTF competitions. A small size and light weight makes BeeCTF a good platform to be hosted even in a small computer such as Raspberry Pi effectively. Built on Laravel 8, BeeCTF is easy to install and run even if your hardware is more limited.

Requirements

BeeCTF requires PHP version 7.3.0 with composer and NodeJS.

Installation

Local

Installation of BeeCTF in traditional way is easy:

git clone https://github.com/Newman101/BeeCTF
composer install
composer update
php artisan key:generate
php artisan user:create-admin

In order to build NPM dependencies for development purposes, please run:

npm install
npm run dev

Please note: pngquant dependency requires libpng-dev library, so it must be installed first in order to get the npm to build successfully. Otherwise, the result will be ELIFECYCLE error.

As BeeCTF is built on Laravel, please make sure to set the correct parameters in the .env file. To run the system after installation, you can use your own web server (such as Nginx or Apache) or use built-in server by:

php artisan serve

Docker

With Docker (currently for development purposes only, the production image is work in progress):

git clone https://github.com/Newman101/BeeCTF
composer install
composer update
docker-compose build
docker-compose up -d
docker-compose exec app php artisan migrate
docker-compose exec app php artisan user:create-admin

After creating an administrative user and database connection, the system is ready to use.

In order to debug any potential issues regarding Docker build, you have a docker-compose shell access with:

docker-compose exec app sh
docker-compose exec mysql sh
docker-compose exec webserver sh

Alternatively, you can also check which services are up:

docker-compose ps

There is an internal API available. This API is used for various purposes, including listing challenges, categories, and getting scoreboard on the command line.
