In this chapter, we had a look at how to install Docker, including acquiring it from https://www.docker.com/, setting up a machine learning Docker file, sharing data back with your host computer, and then finally, running a REST service to provide the environment we'll be using throughout this book.
In the next chapter, we're going to dive in and start looking at actual data. Then, we're going to start by understanding how to take image data and prepare it for use in machine learning models.
