Loading...Introduction to eBPF and Cilium
Last quarter, our team discovered the power of eBPF and Cilium in securing and managing our Kubernetes network policies. We were struggling with the default Kubernetes networking model, which was causing performance issues and security concerns. After months of research and testing, we finally found a solution that worked for us - Cilium 1.13 with eBPF v2.
What is eBPF?
eBPF (extended Berkeley Packet Filter) is a technology that allows us to run sandboxed programs in the Linux kernel. It's a game-changer for network security and observability. With eBPF, we can write custom programs that can inspect and modify network traffic at the kernel level.
What is Cilium?
Cilium is an open-source project that provides a network policy framework for Kubernetes. It uses eBPF to provide a more secure and efficient way of managing network policies. Cilium allows us to define network policies based on labels, namespaces, and other criteria, and it enforces those policies at the kernel level.
