Kubernetes Networking, Decoded

Kubernetes, the de facto standard for container orchestration, has revolutionized modern application deployment. However, its networking model remains a significant challenge for developers and operators alike. This book demystifies the complex Kubernetes networking landscape, tackling core concepts like CNI (Container Network Interface), pod networking, service discovery, and the crucial role of network policies. We decode the architecture that allows microservices to communicate seamlessly, whether they are on the same node or across a vast, distributed cluster. We also explore advanced topics like eBPF and service meshes which are at the forefront of the cloud-native ecosystem.

Authored by a team of seasoned cloud-native experts and Certified Kubernetes Administrators (CKA), this book is born from years of real-world experience. We have a proven track record of designing and troubleshooting production-grade microservices networks for large-scale enterprises. Our insights are battle-tested, providing you with a practical, no-nonsense guide that goes beyond theoretical knowledge. We address common pitfalls and offer solutions that we've successfully implemented to build resilient and secure Kubernetes networking infrastructure.
