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>

Stacks


There is also the Stacks section. Stacks are a collection of services similar to what you would think of when you are using Docker Compose.

Let's take a look at this section, because it can be very useful while using development environments or for testing.

After we click on Create your first stack, we are taken to a page that is similar to the following screenshot:

In this screenshot, we can see that we need pieces of information.

We need a name for our stack and we need the stackfile contents. In our case, we are going to use our trustworthy MySQL example and call our stack mysql.

For our stackfile, we are going to use one of the resources that Tutum encourages us to explore. In the bottom section under the Stackfile field, there is an option to get a Stackfile from the Stackfile registry, which is located at https://Stackfiles.io.

Upon entering stackfiles.io, we are presented with an easy search box.

Again, for our test, we want to find the mysql stackfile, so we enter mysql in the...
