Execution

Grepmarx is provided with a configuration to be executed in Docker and Gunicorn.

Docker execution


Make sure you have docker-composer installed on the system, and the docker daemon is running. The application can then be easily executed in a docker container. The steps:

Get the code

$ git clone https://github.com/Orange-Cyberdefense/grepmarx.git
$ cd grepmarx

Start the app in Docker

$ sudo docker-compose pull && sudo docker-compose build && sudo docker-compose up -d

Visit http://localhost:5000 in your browser. The app should be up & running.

Note: a default user account is created on first launch (user=admin / password=admin). Change the default password immediately.

Gunicorn


Gunicorn 'Green Unicorn' is a Python WSGI HTTP Server for UNIX. A supervisor configuration file is provided to start it along with the required Celery worker (used for security scans queuing).

Install using pip

$ pip install gunicorn supervisor

Start the app using gunicorn binary

$ supervisord -c supervisord.conf

Visit http://localhost:8001 in your browser. The app should be up & running.

Note: a default user account is created on first launch (user=admin / password=admin). Change the default password immediately.

Build from sources

Get the code

$ git clone https://github.com/Orange-Cyberdefense/grepmarx.git
$ cd grepmarx

Install virtualenv modules

$ virtualenv env
$ source env/bin/activate

Install Python modules

PostgreSQL connector (Production) $ # pip install -r requirements-pgsql.txt" dir="auto">
$ # SQLite Database (Development)
$ pip3 install -r requirements.txt
$ # OR with PostgreSQL connector (Production)
$ # pip install -r requirements-pgsql.txt

Install additionnal requirements

# Dependency scan (cdxgen / depscan) requirements
$ sudo apt install npm openjdk-17-jdk maven gradle golang composer
$ sudo npm install -g @cyclonedx/cdxgen
$ pip install appthreat-depscan

A Redis server is required to queue security scans. Install the redis package with your favorite distro package manager, then:

$ redis-server

Set the FLASK_APP environment variable

$ export FLASK_APP=run.py
$ # Set up the DEBUG environment
$ # export FLASK_ENV=development

Start the celery worker process

$ celery -A app.celery_worker.celery worker --pool=prefork --loglevel=info --detach

Start the application (development mode)

$ # --host=0.0.0.0 - expose the app on all network interfaces (default 127.0.0.1)
$ # --port=5000 - specify the app port (default 5000)
$ flask run --host=0.0.0.0 --port=5000

Access grepmarx in browser: http://127.0.0.1:5000/

Note: a default user account is created on first launch (user=admin / password=admin). Change the default password immediately.
