Demo App for CICD Experimentation

This is a sample application used as part of the CICD Learning Lab. This lab walks the user through setting up a full CICD pipeline that will monitor a GitHub repo for changes and build a container based on the changes, publish it to Docker Hub, update a Production app deployment and leverage Cisco Spark to update on status.

The application itself is a very basic "Hello World" application written in Python and leveraging Flask as an interface.
