Overview of this book

<p><span id="description" class="sugar_field">Docker has been a game-changer when it comes to virtualization – it has now grown to become a key driver of innovation beyond system administration, having an impact on the world of web development and more. But how can you make sure you’re keeping up with the innovations that it’s driving? How can you be sure you’re using it to its full potential? Mastering Docker shows you how – it not only demonstrates how to use Docker more effectively, it also helps you rethink and reimagine what’s possible with Docker.</span></p> <p><span class="sugar_field"><span id="description" class="sugar_field"> Covering best practices to make sure you’re confident with and the basics, such as building, managing and storing containers, before diving deeper into Docker security, you’ll find everything you need to help you extend and integrate Docker in new and innovative ways. You’ll learn how to take greater control over your containers using some of Docker’s most sophisticated and useful tools, such as Docker compose and Docker swarm, before bringing together everything you already know and have learned to put your containers into production and monitor them for safety and performance.</span></span></p> <p><span class="sugar_field"><span class="sugar_field"><span id="description" class="sugar_field"> Beyond this, you’ll also explore even more advanced strategies, as you learn how to extend and integrate Docker with cloud platforms such as Heroku and OpenStack, and how tools such as Kubernetes can improve the way you manage large-scale container orchestration. With further guidance on how you can use configuration management tools such as Puppet, Chef and PowerShell, by the end of the book you’ll have a broad and detailed sense of exactly what’s possible with Docker – and how seamlessly it fits with a range of other platforms and tools.</span></span></span></p>

Summary


In this chapter, you looked at the Docker commands that can be used to manage your containers, viewing their status and looking inside them to see what they are doing.

To perform tasks, we looked at how we can execute commands against our running containers. This will lay the groundwork, so you understand what is going on behind the scenes if you use a GUI application to manage containers.

We also took a look at utilizing your existing management suite and using it to cover more ground, including your Docker containers. We took a look at four major management suites that you can use to manage your Docker containers.

We lastly took a look at Docker Swarm that hopefully got you excited for the later chapter on Docker Swarm. With Docker Swarm, we can cluster our containers, view where all our containers are running across multiple Docker hosts, and use it for discovery services to help scale our environments.

In the next chapter, we will be looking at Docker security—the topic that is always...
