Dockerfile

# Coturn TURN server in Docker
#
# This Dockerfile creates a container which runs a Coturn TURN server suitable
# for use with Spreed WebRTC.
#
# Install Docker and then run `docker build -t docker-webrtc-turnserver .` to
# build the image.
#
# Due to the nature of TURN, the container needs to use the hosts network. To
# configure the details, create the config file `data/config`. See the example
# in `data/config.example` for some ideas.
# ```
#
# Afterwards run the container like this:
#
#   ```
#   docker run --rm --net=host --name my-spreed-turnserver -i -v `pwd`/data:/srv -t spreed-turnserver
#   ```
#
# This runs the container with the settings as defined in the config file which is # made available to the container using the volume (-v) option. This volume is also
# used as storage for persistent data created by the TURN server.
