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>

Where to start?


When we start thinking about putting Docker into our production environment, we first need to know where to start. This sometimes can be the hardest part of any project. We first need to start by setting up our Docker hosts and then start running containers on them. So, let's start here!

Setting up hosts

Remember, as it was mentioned in the earlier chapter, that setting up hosts will require us to tap into our Docker Machine knowledge. We can deploy these hosts to different environments, including cloud hosting. To take a walk down memory lane, let's look at how we go about doing this:

$ docker-machine create --driver <driver_name> <host_name>

Now, there are two values that we can manipulate: <driver_name> and <host_name>. The host name can be whatever you want it to be. But I recommend that it should be something that would help you understand its purpose. The driver name on the other hand has to be the location where you want to create the host. If...
