In this chapter, you will learn the general procedures for building Docker images. Later chapters will focus on the processes of building specific Docker images.

Basic questions about the Ruby on Racetracks Docker build procedures are in the FAQ. Topics addressed include how to build Docker images on your local machine, how GitLab CI tools are used to generate and push Docker images, why GitLab's Docker repository is better than Docker Cloud, and why GitLab CI is better than Docker Cloud's automated build feature.
