Overview of this book

Docker is the de facto standard for containerizing apps, and with an increasing number of software projects migrating to containers, it is crucial for engineers and DevOps teams to understand how to build, deploy, and secure Docker environments effectively. Docker for Developers will help you understand Docker containers from scratch while taking you through best practices and showing you how to address security concerns. Starting with an introduction to Docker, you’ll learn how to use containers and VirtualBox for development. You’ll explore how containers work and develop projects within them after you’ve explored different ways to deploy and run containers. The book will also show you how to use Docker containers in production in both single-host set-ups and in clusters and deploy them using Jenkins, Kubernetes, and Spinnaker. As you advance, you’ll get to grips with monitoring, securing, and scaling Docker using tools such as Prometheus and Grafana. Later, you’ll be able to deploy Docker containers to a variety of environments, including the cloud-native Amazon Elastic Kubernetes Service (Amazon EKS), before finally delving into Docker security concepts and best practices. By the end of the Docker book, you’ll be able to not only work in a container-driven environment confidently but also use Docker for both new and existing projects.

Chapter 13: Docker Security Fundamentals and Best Practices

As we wish to ensure that our containers are hardened for both development and production environments, there are many techniques and best practices we can implement to achieve this task. In many cases, it is simply a case of modifying existing commands or behaviors you've learned throughout this book to add an extra layer of security to your practices.

Within this chapter, we will be building upon the foundational knowledge we have of Docker and container security. This will involve hands-on exercises in building and modifying containers. Covering subjects as varied as image security through the usage of Docker commands and signed images, upon completing the following exercises, you should feel comfortable in applying these skills in a real-world development and DevOps environment.

In this chapter, we're going to cover the following main topics:

  • Docker image security: Here, we will learn about image...
