Overview of this book

Docker has been a game-changer when it comes to how modern applications are deployed and created. It has now grown into a key driver of innovation beyond system administration, with an impact on the world of web development. But how can you make sure you're keeping up with the innovations it's driving, or be sure you're using it to its full potential? Mastering Docker shows you how; this book not only demonstrates how to use Docker more effectively, but also helps you rethink and reimagine what's possible with it. You will cover concepts such as building, managing, and storing images, along with best practices to make you confident, before delving more into Docker security. You'll find everything related to extending and integrating Docker in new and innovative ways. Docker Compose, Docker Swarm, and Kubernetes will help you take control of your containers in an efficient manner. By the end of the book, you will have a broad, yet detailed, sense of what's possible with Docker, and how seamlessly it fits in with a range of other platforms and tools.

Summary

In this chapter, we covered some basic information that you should already know (or now know) for the chapters ahead. We went over the basics of what Docker is, and how it fares compared to other host types. We went over the installers, how they operate on different operating systems, and how to control them through the command line. Be sure to remember to look at the requirements for the installers to ensure you use the correct one for your operating system.

Then, we took a small dive into using Docker and issued a few basic commands to get you started. We will be looking at all of the management commands in future chapters, to get a more in-depth understanding of what they are, as well as how and when to use them. Finally, we discussed the Docker ecosystem and the responsibilities of each of the different tools.

In the next chapters, we will be taking a look at how to build base containers, and we will also look in depth at Dockerfiles and places to store your images, as well as using environmental variables and Docker volumes.
