eBPF for networking in a Kubernetes cluster brings some advantages such as performance, lower resource utilization, shorter routing path, etc. However, due to the compiler nature of an eBPF program, it is not a trivial task to troubleshoot an issue. In this session, we will discuss the open-source tools that are embedded in Project Calico that you can use to gain insight into the inner working of the kernel and associated eBPF programs for networking and security.
