This facilitates instant metrics retrieval and the implementation of network routing and security policies. Additionally, eBPF empowers us to reshape traffic at a low level with XDP, which delivers high-performance programmable packet processing seamlessly integrated with the kernel. This revolutionary impact extends to the Kubernetes networking landscape, as eBPF serves as the core technology behind projects like Cilium and its CNI plugin that provides high-performance network capabilities, but such powerful technologies remain enigmatic for many. The objective of this workshop is to dive into the inner workings of these technologies, participants will learn the basics of eBPF and CNI, and they will gain hands-on experience in creating a CNI plugin for Kubernetes utilizing eBPF, demystifying the underlying mechanics of eBPF-based projects.
