Containers without Docker: Managing Rootless Infrastructure with Podman Kindle Edition

"Containers without Docker: Managing Rootless Infrastructure with Podman" is a comprehensive guide for modern engineers and system administrators seeking a deep understanding of rootless containerization and the practical adoption of Podman. The book begins by exploring the fundamental principles of rootless containers, tracing their evolution from traditional, daemon-based Docker workflows to the more secure, composable, and user-centric approaches embodied by Podman. Through historical context and technical comparisons, it clearly defines Podman’s distinct role within the container ecosystem, highlighting its strict adherence to Open Container Initiative standards, its foundational reliance on Linux namespaces and capabilities, and its transformative impact on multi-user security in both development and production environments.Delving beneath the surface, the book unpacks the architecture and operational workflow of Podman, with in-depth discussions on its daemonless design philosophy and seamless integration with tools like Buildah for rootless image management. Readers will be guided through all aspects of managing images, orchestrating advanced multi-container deployments, and optimizing persistent storage strategies—without ever requiring elevated privileges. Special attention is paid to network configuration, service exposure best practices, and leveraging systemd for resilient, user-centric automation. The narrative is anchored in real-world use cases, from DevOps automation and CI/CD pipelines to personal workstations and multi-tenant platforms, ensuring its relevance across various operating environments.Security and observability receive particular emphasis throughout, with exhaustive coverage of Linux security modules (SELinux, AppArmor), granular privilege assignment, vulnerability scanning, and policy enforcement. The book also addresses the wider landscape of compliance, auditing, and monitoring, equipping readers with advanced debugging, tracing, and performance profiling techniques. By championing a rootless, standards-based approach to containers, "Containers without Docker" empowers practitioners to build robust, scalable, and secure containerized infrastructures—whether in the cloud, on-premises, or across hybrid environments. This is the definitive resource for those looking to modernize their workflow and confidently adopt Podman at scale. Read more
