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.

Technical requirements

To complete the exercises in this chapter, you'll need Git and Docker on your local workstation. For Mac and Windows users, please install Docker Desktop (https://www.docker.com/products/docker-desktop) as this is how most people using Docker use it on their local workstations. You need to learn more about the options before you choose a production deployment tool.

Depending on what avenues you explore, you may also want to establish accounts with Amazon Web Services, Google Cloud, Microsoft Azure, or Digital Ocean. Most of these services have fairly generous free tiers that may allow you to experiment without spending much money, especially if you only use the services for a short duration. When considering what sort of environment might be suitable for your application, it helps to have multiple options. If you do create resources in the cloud, don't forget to terminate resources that you are done with or are not planning to keep, or you could...
