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>

Chapter 4. Managing Containers

In this chapter, you will learn how to manage your containers and the different ways you can go about doing so. This chapter will focus on the command line (as other chapters will cover other tools) to help lay the groundwork for understanding what the GUI-based apps are doing in the background. Sometimes, the command line is the best tool to help troubleshoot containers as well! Troubleshooting containers will be covered more in depth in Chapter 10, Shipyard. Apart from managing the containers, we will also cover topics on how to manage your images.

To be specific, the following topics will be covered:

  • Docker commands: We will cover the Docker commands you can use to manage your containers

  • Using existing suite: We will cover it using your existing management suites such as Chef or Puppet, plus some others to manage your containers

  • Docker Swarm: You will have a brief overview of Docker Swarm, which we will be covering more in depth in a later chapter
