SaltyRTC Signalling Server

CircleCI codecov PyPI Gitter

This is a SaltyRTC server implementation for Python 3.5+ using asyncio.

Note

On machines where Python 3 is not the default Python runtime, you should use pip3 instead of pip.

Prerequisites

sudo apt-get install python3 python3-pip

We recommend using venv to create an isolated Python environment:

pyvenv venv

You can switch into the created virtual environment venv by running this command:

source venv/bin/activate

While the virtual environment is active, all packages installed using pip will be installed into this environment.

To deactivate the virtual environment, just run:

deactivate

If you want easier handling of your virtualenvs, you might also want to take a look at virtualenvwrapper.

Installation

If you are using a virtual environment, activate it first.

Install the module by running:

pip install saltyrtc.server

The dependency libnacl will be installed automatically. However, you may need to install libsodium for libnacl to work.

Command Line Usage

The script saltyrtc-server will be automatically installed and provides a command line interface for the server.

Run the following command to see detailed usage information:

saltyrtc-server --help

All command line options are also available as environment variables by prefixing them with SALTYRTC_SERVER_ and the upper case command name, followed by the option name in upper case. For example: SALTYRTC_SERVER_SERVE_PORT=8765.

Quick Start

Generate a new private permanent key:

saltyrtc-server generate /path/to/permanent-key

Run the following command to start the server on any address with port 8765:

saltyrtc-server serve \
    -p 8765 \
    -tc /path/to/x509-certificate \
    -tk /path/to/key \
    -k /path/to/permanent-key

Alternatively, provide the options via environment variables:

export SALTYRTC_SERVER_SERVE_PORT=8765 \
       SALTYRTC_SERVER_SERVE_TLSCERT=/path/to/x509-certificate \
       SALTYRTC_SERVER_SERVE_TLSKEY=/path/to/key \
       SALTYRTC_SERVER_SERVE_KEY=/path/to/permanent-key
saltyrtc-server serve

Docker

You can also use our official Docker images to run the server:

docker run \
    -v /path/to/cert-and-keys:/var/saltyrtc \
    -p 8765:8765
    -it saltyrtc/saltyrtc-server-python:<tag> serve \
    -p 8765 \
    -tc /var/saltyrtc/x509-certificate \
    -tk /var/saltyrtc/key \
    -k /var/saltyrtc/permanent-key

The above command maps port 8765 of the server within the container to port 8765 on the host machine.

Of course it is also possible to use environment variables to provide the options, as explained in the previous section.

Contributing

If you want to contribute to this project, you should install the optional dev requirements of the project in an editable environment:

cd saltyrtc-server-python
pip install -e .[dev]

Before creating a pull request, it is recommended to run the following commands to check for code style violations (flake8), optimise imports (isort), do a static type analysis and run the project's tests:

flake8 .
isort -rc .
