Kubernetes Contributor Summit North America 2024

This session is to provide an overview of the current state of multi networking within Kubernetes, highlighting the work done by the Multi-Network WG which sits at an intersection with numerous ongoing efforts and groups – the Device Management WG and structured parameters for DRA, container runtimes, CNI (and the future of CNI) and naturally – SIG-Network. There are a number of challenges surrounding a decision to work out of core, paths forward for integrated network functionality (like services), and legacy implementations.

We'll address some of the legacies of what previous technologies and paradigms folks have been using, such as NetworkAttachmentDefinitions, and Network Service Mesh – and talk about the trade-offs these projects had working out of core, and what we can do to reduce those trade offs – notably, with service-like functionality.

This includes discussing the ongoing development of the Multi-Network KEP Phase I, some of the POCs around combining technologies, and the move to using CRDs. Most importantly, the session aims to gather feedback and foster discussions on the next steps – and especially to get feedback from and alignment with other critical groups.
