The following enhancements have been made to docker/docker-compose * Fixed bug when building the image. * docker-compose up starts the server * Scaffolding inside the container respect the ownership of the files outside it * Volumes are tagged as 'delegated' in order to improve performance for mac/windoze users. * bundler stores packages in a volume. This whay new packages can be added without rebuilding the image: ```bash docker-compose run app bundle install ```
