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.

To get the most out of this book

In this book, we will guide you through the installation and use of Podman 3 or later, and its companion tools, Buildah and Skopeo. The default Linux distribution used in the book is Fedora Linux 34 or later but any other Linux distribution can be used. All commands and code examples have been tested using Fedora 34 or 35 and Podman 3 or 4, but they should work also with future version releases.

If you are using the digital version of this book, we advise you to type the commands yourself or access the code from the book's GitHub repository (a link is available in the next section).

Doing so will help you avoid any potential errors related to the copying and pasting of code.
