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 1: Introduction to Docker

Docker is a technology that allows entire applications and their environments to be encapsulated within individual containers. When multiple versions of these containers are run on a single machine, they are sandboxed from one another as if running on their own dedicated machines.

Docker is open source, which fits well with running Linux in containers, as well as numerous available open source components that help build complex systems. It is the logical progression of technologies used for hosting and backend development over the past decade or longer. This progression has moved from a physical kind of hosting to a logical one and has been driven by several requirements. These requirements include reliability, reachability, scalability, and security.

This book is divided into three sections. The first is an introduction to Docker, focusing on local development. The second describes the methodology for testing, deploying, and scaling applications. The third goes into detail about security when using a container-based design.

In this chapter, we will review the history of hosting and backend solutions with a focus on how Docker came to be a widely used technology.

The following topics will be covered in this chapter:

  • Origins of hosting services
  • Types of hosting services – co-location
  • Types of hosting services – self-hosting
  • The benefits of data centers
  • How virtualization works
  • The power requirements at data centers
  • How virtualization is a solution for data centers and the invention of the cloud
  • How containers are a bigger win for data centers and hosting
