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>

Docker Registry


In this section, we will be looking at Docker Registry. Docker Registry is an open source application that you can run anywhere you please and store your Docker image in. We will look at the comparison between Docker Registry and Docker Hub and how to choose among the two. By the end of the section, you will learn how to run your own Docker Registry and see whether it's a true fit for you.

An overview of Docker Registry

Docker Registry, as stated earlier, is an open source application that you can utilize to store your Docker images on a platform of your choice. This allows you to keep them 100% private if you wish or share them as needed. The registry can be found at https://docs.docker.com/registry/.

This will run you through the setup and the steps to follow while pushing images to Docker Registry compared to Docker Hub. Docker Registry makes a lot of sense if you want to roll your own registry without having to pay for all the private features of Docker Hub. Next, let's...
