docker-janus
docker-janus is a Debian 8 based docker image for Meetecho's Janus Gateway
Description
All the janus docker builds I have seen in hub.docker.com 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 hub.docker.com
You can use this image directly from hub.docker.com 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!

build criteria

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

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 .
