Selenoid supports showing video via VNC. What you need to do is just grab it from respective port. Here is one possible way to record video from VNC.

Requirements:

1. Selenoid must be running in as a binary (not as Docker container) otherwise the mapped ports are null.
2. Docker APIs should be exposed to the outside world. (http://www.virtuallyghetto.com/2014/07/quick-tip-how-to-enable-docker-remote-api.html)

How to do that. One possible solution is to use vnc2flv script.

1. Download the script: $ wget https://pypi.python.org/packages/1e/8e/40c71faa24e19dab555eeb25d6c07efbc503e98b0344f0b4c3131f59947f/vnc2flv-20100207.tar.gz\#md5\=8492e46496e187b49fe5569b5639804e

2. Unpack the archive: $ tar zxf vnc2flv-20100207.tar.gz

3. Install the script: $ python setup.py install --prefix=/usr/local

4. Record the video: get Docker container ID via Selenoid /status and then find with Docker commands which port is mapped to the container port 5900 (the VNC port). Then type: flvrec.py -P <filename_for_password_file> -o <output_video_filename> <hub_host> <the_vnc_port>, e.g. flvrec.py -P password.txt -o /tmp/selenoid_videos/gimme_love.flv 172.31.11.135 32774.

5. Saved video file can be found in /tmp/selenoid_videos/gimme_love.flv.
