From Kubernetes Objects to Network Packet Pipelines - Deep Dive into OpenShift Networking

Explore a deep dive into OpenShift networking implementation in this conference talk from DevConf.CZ 2024. Delve into the intricacies of ovn-kubernetes (OVN-K8s), the default certified Container Network Interface (CNI) for OpenShift since version 4.12. Discover how OVN-K8s leverages the open-source Open Virtual Networking (OVN) and Open vSwitch (OVS) projects to provide a robust Kubernetes networking solution. Focus on the packet processing within the kernel OVS datapath and learn how to map these processing steps to higher layers, including OVS OpenFlow rules, OVN logical flows, OVN logical network constructs, and Kubernetes objects. Gain valuable insights from speakers Ales Musil and Dumitru Ceara as they unravel the complexities of OpenShift networking in this 33-minute presentation.
