Instructions for Haze:

1. • Open the command prompt and type in the following:
     docker pull fungover/haze(This downloads the Docker image)

2. • Start a new container with the image, mapping the port 6379 on the host to port 6379 on the container: docker run -p 6379:6379 fungover/haze

   • You can change the behaviour of the server by putting in environment variables when starting the container. For example, you can set the server port to 6440. To do this: docker run -p 6440:6440 -e HAZE_PORT=6440 fungover/haze.
