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, we took a dive into Docker Swarm. We took a look at how to install Docker Swarm and the Docker Swarm components; these are what make up Docker Swarm. We took a look at how to use Docker Swarm; joining, listing, and managing Swarm nodes. We reviewed the Swarm commands and how to use them. We also covered some advanced Docker Swarm topics such as advanced scheduling for your jobs, discovery services to discover new containers to add to Docker Swarm, and the Docker Swarm API that you can use to tie your own code to perform the Swarm commands.

In the next chapter, we will take a look at running Docker in production. We will take everything you have learned in all of the previous chapters and put them into production. We will look at how to monitor your containers and the safeguards you can put into place to help with container recovery. We will also look at how you can extend into external platforms such as Heroku.
