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 Hub


In this section, we will cover the locations you can store the images you will be creating. There are several different areas to store these, ranging from a location in the cloud that can be set to public, where anyone can access and use them, to private, again a place in the cloud that can only be accessed by those you give permission to. You can also host your own repository, where you can store your own images. You can also purchase a Docker subscription (Docker Hub Enterprise) that provides you with what you need to deploy to the cloud or locally, and also comes along with commercial support from Docker.

The Docker Hub location

The Docker Hub is a location on the cloud, where you can store and share images that you have created. You can also link your images to the GitHub or Bitbucket repositories that can be built automatically based on web hooks. We will be discussing web hooks in the next chapter and will go over all the pieces required for that setup. There are two types...
