Summary
In summary, we have learned how to work with Docker in this chapter, and while this is only a brief overview, I suggest you head over to the documentation and read more in depth on the concepts of Dockerfiles, Composefiles, the Docker Engine, and Docker Compose. Docker is an invaluable tool for development, testing, and production and as we progress through the following chapters, we will use these concepts extensively. In the next chapter, we are going to look at testing, which builds on all of the things you have learned so far.
