Mastering Docker - Third Edition

Overview of this book

Docker has been a game-changer when it comes to how modern applications are deployed and created. It has now grown into a key driver of innovation beyond system administration, with an impact on the world of web development. But how can you make sure you're keeping up with the innovations it's driving, or be sure you're using it to its full potential? Mastering Docker shows you how; this book not only demonstrates how to use Docker more effectively, but also helps you rethink and reimagine what's possible with it. You will cover concepts such as building, managing, and storing images, along with best practices to make you confident, before delving more into Docker security. You'll find everything related to extending and integrating Docker in new and innovative ways. Docker Compose, Docker Swarm, and Kubernetes will help you take control of your containers in an efficient manner. By the end of the book, you will have a broad, yet detailed, sense of what's possible with Docker, and how seamlessly it fits in with a range of other platforms and tools.

The Docker Bench Security application

In this section, we will cover the Docker Benchmark Security application that you can install and run. The tool will inspect the following:

  • The host configuration
  • The Docker daemon configuration
  • The Docker daemon configuration files
  • Container images and build files
  • Container runtime
  • The Docker security operations
  • Docker Swarm configuration

Look familiar? It should, as these are the same items that we reviewed in the previous section, only built into an application that will do a lot of the heavy lifting for you. It will show you what warnings arise within your configurations, and will provide information on other configuration items, and even the items that have passed the test.

Now, we will look at how to run the tool, a live example, and what the output of the process means.
