Podman for DevOps

By: Alessandro Arrichiello, Gianni Salinetti

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 3: Running the First Container

In the previous chapters, we discussed the history of containers, their adoption, and the various technologies that contribute to their spread, while also looking at the main differences between Docker and Podman.

Now, it’s time to start working with real examples: in this chapter, we will learn about how to get Podman up and running on your preferred Linux operating system so that we can start our first container. We will discover the various installation methods, all the prerequisites, and then start a container.

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

  • Choosing an operating system and installation method
  • Preparing your environment
  • Running your first container
