Overview of this book

As containers have become the new de facto standard for packaging applications and their dependencies, understanding how to implement, build, and manage them is now an essential skill for developers, system administrators, and SRE/operations teams. Podman and its companion tools Buildah and Skopeo make a great toolset to boost the development, execution, and management of containerized applications. Starting with the basic concepts of containerization and its underlying technology, this book will help you get your first container up and running with Podman. You'll explore the complete toolkit and go over the development of new containers, their lifecycle management, troubleshooting, and security aspects. Together with Podman, the book illustrates Buildah and Skopeo to complete the tools ecosystem and cover the complete workflow for building, releasing, and managing optimized container images. Podman for DevOps provides a comprehensive view of the full-stack container technology and its relationship with the operating system foundations, along with crucial topics such as networking, monitoring, and integration with systemd, docker-compose, and Kubernetes. By the end of this DevOps book, you'll have developed the skills needed to build and package your applications inside containers as well as to deploy, manage, and integrate them with system services.

Chapter 1: Introduction to Container Technology

Container technology has old roots in operating system history. For example, do you know that part of container technology was born back in the 1970s? Despite their simple and intuitive approach, there are many concepts behind containers that deserve a deeper analysis to fully grasp and appreciate how they made their way in the IT industry.

We're going to explore this technology to better understand how it works under the hood, the theory behind it, and its basic concepts. Knowing the mechanics and the technology behind the tools will let you easily approach and learn the whole technology's key concepts.

Then, we will also explore container technology's purpose and why it has spread to every company today. Do you know that 50% of the world's organizations are running half of their application base as containers in production nowadays?

Let's dive into this great technology!

In this chapter, we're going to ask the following questions:

  • What are containers?
  • Why do I need a container?
  • Where do containers come from?
  • Where are containers used today?
