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>

Summary


In this chapter, we covered some aspects of Docker security. First, we took a look at containers versus typical virtual machines with regards to security. We looked at the good, the not so bad, and what to look out for.

We then took a look at what Docker commands we can use for security purposes. We first took a look at read-only containers, so we can minimize what we are exposing to other containers. We then viewed what is done to the images that you have running. It is important to know what is done on these containers, so you have a trail of activity.

Next, we took a look at the Center for Internet Security guidelines for Docker. This guide will assist you in setting up multiple aspects of your Docker environment. Lastly, we took a look at the Docker bench for security. We looked at how to get it up and running and ran through an example of what the output would look like once it has been run. We then took a look at the said output to see what all it meant. Remember the six items...
