The guestbook example shows how to build a simple multi-tier web application using Kubernetes and Docker. The application consists of a web front end, Redis master for storage, and replicated set of Redis slaves, all for which we will create Kubernetes deployments, pods, and services.

There are two versions of this application. Version 1 (in the v1 directory) is the the basic guestbook application in go with deployment files for you to exampine at your convenience. Version 2 (in the v2 directory) extends the guestbook example with additional functionality to call the IBM Watson Tone Analyzer service.

The v2 directory contains the application version that will be the focus for the digital developer conference hands-on lab.
