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>

Keeping your containers in check


What are some of the tools that we can use to keep our containers the way we have set them up? How do we ensure that they stay the way we want them to? How do we ensure that if they do drift off or things change on them, we are able to put them back in place to where we want them to be? Let's see how we can achieve that.

Kubernetes

Kubernetes is an open source project that was developed by Google to help with the automating deployment of your containers as well as scaling and the operations of your containers, not only on one host, but across multiple hosts. Kubernetes has been set to work on almost every environment that can be imagined, from locally in a Vagrant or VMware environment to cloud solutions such as AWS or Microsoft Azure. There will be some terminology that will need to be learned beyond the Docker terms, but if you understand how Docker operates, learning the Kubernetes terminology will come naturally. For example, instead of hosts, Kubernetes...
