How To

With Docker Hub

docker pull epflsti/octave-x11-novnc-docker
docker run -p 8083:8083 -ti epflsti/octave-x11-novnc-docker:latest
firefox http://localhost:8083
octave is launched, just run some script e.g. my_sombrero.m

Adding the parameter -e SCREEN_RESOLUTION=<width>x<height> the screen size displayed is adjusted to the one in the environment variable. By default it is 1024x768.

If your source files are in your host then just add the -v parameter for example

docker run -p 8083:8083 -ti -v $(pwd):/source epflsti/octave-x11-novnc-docker:latest

Manual Build

docker build -t epflsti/octave-x11-novnc-docker:latest .
