Demystifying IPv6 Kubernetes

This talk delves into the intricacies of IPv6 within Kubernetes, addressing common myths and exploring the realities of its implementation. Antonio Jose Ojea Garcia (Kubernetes maintainer) and Fernando Gont (IPv6 protocol specification author) provide an exhaustive analysis of Kubernetes' IPv6 architecture. They cover the evolution of IPv6 support in Kubernetes, from single-stack to dual-stack clusters, and discuss how the project strives for backward compatibility. The presentation also touches on the fundamental concepts of Kubernetes networking, including Pod and Service networking, and explores potential future directions for leveraging IPv6's addressing capabilities, such as providing Global Unicast Addresses (GUAs) to services and pods.
