docker-janus is a Debian 8 based docker image for Meetecho's Janus Gateway


All the janus docker builds I have seen in were all ubuntu based and/or of some redhat flavor. I successfully build janus in debian 7 and 8 before, so I thought it would be a good way to practice docker best practices and provide a debian based image at the same time.

For the automated build go to

You can use this image directly from by issuing the following docker commands:

docker pull mcroth/docker-janus:latest

UPDATE: Added a new branch with tklx/base as the build image which drastically reduces the docker image size. Both latest and tklx tags are available from the hub.

Many thanks for meetecho for providing us Janus Gateway!

I have tried to build the image with docker best practices at hand. Should there be anything of note you notices, please do not hesitate to leave a comment!

Visiting http://localhost:8088/janus/info in your browser should provide you with the build info of janus in JSON format.

A full set of default janus config files are in ./janus folder, which is referenced as a volume in the docker-compose.yml file for docker-compose to use.

build criteria

janus-gateway is built with the following configured options disabled, as I do not have the need for them to be enabled by default:

./configure --prefix=/opt/janus --enable-post-processing --disable-docs --disable-boringssl --disable-mqtt --disable-rabbitmq

default build

There is a Makefile, with some directives on building janus. Have a look at that file and check the options. Issuing a make will run the default build with the options set below.

DataChannels support:      yes
BoringSSL (no OpenSSL):    no
Recordings post-processor: yes
TURN REST API client:      yes
Doxygen documentation:     no
    REST (HTTP/HTTPS):     yes
    WebSockets:            yes (new API)
    RabbitMQ:              no
    MQTT:                  no
    Unix Sockets:          yes
    Echo Test:             yes
    Streaming:             yes
    Video Call:            yes
    SIP Gateway:           yes
    Audio Bridge:          yes
    Video Room:            yes
    Voice Mail:            yes
    Record&Play:           yes
    Text Room:             yes

docker build --build-arg

--build-arg provides away to override some build runtime arguments. Have a look at the Dockerfile for the ARG arguments to override.

Example build with rabbitmq, paho-mqtt, boringssl enabled, and data-channels disabled:

root@mcroth:~/sandbox/docker-janus# docker build --build-arg JANUS_WITH_BORINGSSL=1 --build-arg JANUS_WITH_PAHOMQTT=1 --build-arg JANUS_WITH_RABBITMQ=1 --build-arg JANUS_WITH_DATACHANNELS=0 -t mcroth/docker-janus:latest .
