Compile the project:

$ docker image build -t chrisdone/duta-deploy docker -f docker/deploy.Dockerfile

You should now have an image chrisdone/duta-deploy on your machine with the deploy.

$ docker images chrisdone/duta-deploy
REPOSITORY              TAG                 IMAGE ID            CREATED             SIZE
