License and set-up
How to set up your development environment? What does our license involve?
License of code contributions
The source code of OSRD is available under the LGPLv3 license. By contributing to the codebase, you consent to the distribution of your changes under the project’s license.
LGPLv3 forbids modifying source code without sharing the changes under the same license: use other people’s work, and share yours!
This constraint does not propagate through APIs: You can use OSRD as a library, framework or API server to interface with proprietary software. Please suggest changes if you need new interfaces.
Set things up
Most OSRD developers use Linux (incl. WSL). Windows and MacOS should work too, but you may run into some issues.
Get the source code
- Install
git.1 - Open a terminal2 in the folder where the source code of OSRD will be located
- Run
git clone https://github.com/OpenRailAssociation/osrd.git
Launch the application
Docker is a tool which greatly reduces the amount of setup required to work on OSRD:
- download the latest development build:
docker compose pull - start OSRD:
docker compose up - build and start OSRD:
docker compose up --build - review a PR using CI built images:
TAG=pr-XXXXX docker compose up --no-build --pull always
To get started:
- Install
docker - Follow OSRD’s README.
