Kubernetes was built to run distributed systems over a cluster of machines. The very nature of distributed systems makes networking a central and necessary component of Kubernetes deployment, and understanding the Kubernetes networking model will allow you to correctly run, monitor and troubleshoot your applications running on Kubernetes. Networking is a vast space with a lot of mature technologies. For people unfamiliar with the landscape, this can be uncomfortable because most people have existing preconceived notions about networking, and there are a lot of both new and old concepts to understand and fit together into a coherent whole. A non-exhaustive list might include technologies like network namespaces, virtual interfaces, IP forwarding, and network address translation. This guide intends to demystify Kubernetes networking by discussing each of Kubernetes dependent technologies along with descriptions on how those technologies are used to enable the Kubernetes networking model.
