Chapter 6. Creating a Simple Web App

In this chapter, we’ll turn our “Hello World!” program into a simple web app that generates a unique image for users when they enter some text. These images are sometimes known as identicons and can be used to identify users by providing a unique image generated from their username or IP address. At the end of this chapter, you’ll have a basic working application that we will extend and play with in the following chapters. By creating this application, we’ll see how to compose Docker containers to build a fully functioning system and how this naturally leads to a microservice approach.
