Twitch VPS Streamer

Docker image to run Chrome on a linux VPS and stream it on Twitch

Disclaimer

Code is partly based on https://github.com/stephen-fox/chrome-docker and other forks of it.

Features

Runs xvfb with the window manager fluxbox, vncso you can connect from remote and then chrome. It includes a separate script to start the stream on Twitch by launching ffmpeg. You can even include an external radio stream as audio source.

Build image

Just as every other image: docker build . -t twitch-streamer

Launch Container

docker run -p 127.0.0.1:5900:5900 --rm -v /etc/localtime:/etc/localtime:ro -v /dev/shm/:/dev/shm/ -e TZ=Europe/Berlin -e VNC_SERVER_PASSWORD=<password> -e SERVER_KEY=<your streaming key from twitch> --user chrome --name twitch-streamer --privileged twitch-streamer

Note: The MacOS VNC client will not be able to login unless you set a password for the VNC server.

Once the container is running, you can VNC into it at 127.0.0.1 (if you are running the container on a VPS, you might have to start a ssh tunnel first ssh -L 5900:localhost:5900 my_vps)

Launch Chrome from a terminal window by running.

google-chrome

You can also start Google Chrome by right-clicking the Desktop and selecting:

Applications > Network > Web Browsing > Google Chrome

Launch stream

Once everything is set up, you can launch the stream docker exec -ti twitch-streamer bash /twitch_streamer.sh

If you want to stop it, just press CTRL-C

Security concerns

This image starts a X11 VNC server which spawns a framebuffer. Google Chrome also requires that the image be run with the --privileged flag set. This flag disables security labeling for the resulting container. Be very careful if you run the container on a non-firewalled host.

Some applications (such as Google Chrome) will not run under the root user. A non-root user named chrome is included for such scenarios.
