I was attempting to follow your blog post, however, when running docker-compose build there does not exist a Dockerfile in the docker/development/nginx/ directory so it fails. I added a simple Dockerfile like the following:
FROM fntlnz/nginx:1.8.0
However it has a problem accessing redis after being able to build.
