# Docker needs to run a TURN server to get webrtc traffic to and from it over forwarded ports from the host

# for example <TurnServerPort>3478</TurnServerPort><TurnServerMinPort>50000</TurnServerMinPort><TurnServerMaxPort>50010</TurnServerMaxPort>
# The main server port is overridden by creating a text file called port.txt in the root directory containing the port number, eg: 8090
