Introduction

Dockerfile for installation of a coturn server (tied to a matrix one).

Configuration

To configure run the image with "generate" as argument. You have to setup the server domain and a /data-directory. After this you have to edit the generated config files.

To get the things done, "generate" will create a own self-signed certificate.

This needs to be changed for production usage.

Example:

$ docker run -v /tmp/data:/data --rm -e SERVER_NAME=localhost -e REPORT_STATS=no silviof/docker-matrix generate

Start

Think to forward tcp,udp:3478,5349,49152:65535

For starting you need the port bindings and a mapping for the /data-directory.

$ docker run -d v /tmp/data:/data silviof/docker-matrix start

You may also have to set the external ip of the server in turnserver.conf which is located in the /data volume: external-ip=XX.XX.XX.XX

In case you don't want to expose the whole port range on udp you can change the portrange in turnserver.conf: min-port=XXXXX max-port=XXXXX

Version information

To get the installed synapse version you can run the image with version as argument or look at the container via cat.

$ docker run -ti --rm silviof/docker-matrix version
coturn:  master (88bd6268d8f4cdfdfaffe4f5029d489564270dd6)

# docker exec -it CONTAINERID cat /coturn.version
coturn:  master (88bd6268d8f4cdfdfaffe4f5029d489564270dd6)

build specific arguments

BV_TURN: coturn turnserver version, optional, defaults to master

For building of synapse version v0.11.0-rc2 and coturn with commit a9fc47e add --build-arg --build-arg BV_TURN=a9fc47efd77 to the docker build command.
