Summary

In this chapter, we covered everything from the basic Docker container to extending an existing container, all the way to creating our own service from scratch. Along the way, we covered the most important Docker and Dockerfile commands and how to use them and, even more importantly, where and why to use them. While this was not the most in-depth coverage of the topic, it is just the right amount of depth we need in order to start working on scaling containers in our next chapter.
