Cilium Network Policies with eBPF: The Complete Guide for Developers and Engineers

"Cilium Network Policies with eBPF"

Harnessing the transformative power of eBPF and Cilium, "Cilium Network Policies with eBPF" offers a comprehensive guide to next-generation networking and security within cloud-native environments. The book begins with a rigorous introduction to eBPF’s core architecture, detailing the underlying program constructs, data structures, verification mechanisms, and advanced performance optimizations that make eBPF uniquely suited for high-performance packet processing. Through clear explanations and insightful examples, readers gain the essential grounding to understand how eBPF revolutionizes observability, security, and traffic control at the Linux kernel level.

Building on this technical foundation, the book explores the inner workings of Cilium—a modern networking solution that leverages eBPF to deliver dynamic, fine-grained network policies for Kubernetes and beyond. Delving into topics such as control and data plane separation, policy language design, identity-driven enforcement, and seamless integration with Kubernetes and service meshes, the text guides readers through the full lifecycle of network policy implementation. Emphasis is placed on real-world use cases, from multi-tenancy and zero trust architectures to automated policy generation and advanced troubleshooting with observability tools like Hubble.

The latter chapters address the critical aspects of security, scalability, and operational excellence in production environments. Readers are equipped with best practices for hardening Cilium deployments, ensuring policy integrity, achieving compliance, and responding to incidents in eBPF-rich landscapes. Coverage extends to rolling upgrades, hybrid cloud integrations, CI/CD-driven automation, and the evolving ecosystem of community-driven projects. Concluding with forward-looking perspectives on AI-augmented policy management and emerging use cases in edge and IoT, this book is an indispensable resource for engineers, architects, and security professionals seeking to master modern network policy with Cilium and eBPF.
