Bottle Base Docker Image
The Dockerfile included in the repository creates an image based on the ubuntu 16.04 (latest) or alpine linux (alpine_ image with pip and python dev libraries installed. It also installs the bottle microframework and the gunicorn WSGI server.
The image created will have a user names "apprunner" and group named "apprunner" which are appropriate for running without root privileges. This base image does not switch to that user, as the time and place for that is appropriate for the derived image to determine.
