Hi, here are the instructions for building your docker image with the fuzzy-libmath:
$> git clone https://github.com/verificarlo/fuzzy.git
$> cd fuzzy
$> ./docker/resources/build_fuzzy_libmath_dockerfile.sh <DOCKER_IMAGE> <NEW_NAME>
$> docker run -it <NEW_NAME>
where DOCKER_IMAGE is the name of your docker image to wrap and NEW_NAME the name of the new fuzzy version created.
You can find here an example of fuzzy-libmath on the python image.
