FOSSology is a open source license compliance software system and toolkit. As a toolkit you can run license, copyright and export control scans from the command line. As a system, a database and web ui are provided to give you a compliance workflow. In one click you can generate an SPDX file, or a ReadMe with all the copyrights notices from your software. FOSSology deduplication means that you can scan an entire distro, rescan a new version, and only the changed files will get rescanned. This is a big time saver for large projects.
FOSSology does not give legal advice.
The PHP versions 5.5.9 to 5.6.x are supported to work for FOSSology. FOSSology requires Postgresql as database server and apache httpd 2.4 as web server. These and more dependencies are installed by
FOSSology should work with many Linux distributions.
See https://github.com/fossology/fossology/releases for source code download of the releases.
For installation instructions see Github Wiki
FOSSology comes with a Dockerfile allowing the containerized execution
both as single instance or in combination with an external PostgreSQL database.
Note: It is strongly recommended to use an external database for production
use, since the the standalone image does not take care of data persistency.
A pre-built Docker image is available from Docker Hub and can be run using following command:
docker run -p 8081:80 fossology/fossology
The docker image can then be used using http://IP_OF_DOCKER_HOST:8081/repo user fossy passwd fossy.
Execution with external database container can be done using Docker Compose.
The Docker Compose file is located under the
/install folder can can be run using following command:
cd install docker-compose up
The Docker image allows configuration of it's database connection over a set of environment variables.
- FOSSOLOGY_DB_HOST: Hostname of the PostgreSQL database server.
An integrated PostgreSQL instance is used if not defined or set to
- FOSSOLOGY_DB_NAME: Name of the PostgreSQL database. Defaults to
- FOSSOLOGY_DB_USER: User to be used for PostgreSQL connection. Defaults to
- FOSSOLOGY_DB_PASSWORD: Password to be used for PostgreSQL connection. Defaults to
FOSSology comes with a VagrantFile that can be used to create an isolated environment for FOSSology and its dependencies.
Pre-requisites: Vagrant >= 2.x and Virtualbox >= 5.2.x
git clone https://github.com/fossology/fossology cd fossology/ vagrant up
The server must be ready at http://localhost:8081/repo/ and user can login the credentials using
user: fossy pass: fossy
