Duckling server on the Rasa getting started training course no longer exists

Hi all, I’m checking out the Rasa Certification Course.

The content is a little out of date. It mentions a Duckling server at which is no longer responding. Does anyone have any idea if there is an alternative. Any help much appreciated

EDIT I just fixed this myself by grabbing the Docker image (doh):

docker run rasa/duckling

running happilly at http://localhost:8000
