Hello Paul,

I have attached a patch to reduce the layerindex-web image size further. 
Docker image layers are like git objects and RUN commands can only hide 
files, not remove them once they have been committed. The pip upgrade 
caused the following 'pip install' to fail and was removed.

I recommend docker-compose because much of the information in 
docker/README can be captured in a compose yaml file. It handles the 
network setup and makes managing shared volumes much simpler.
