Beyond printf and tcpdump - Debugging Kubernetes Networking with eBPF

Explore advanced Kubernetes networking debugging techniques using eBPF in this conference talk. Discover how to move beyond traditional tools like printf and tcpdump to efficiently troubleshoot complex networking issues in Kubernetes clusters. Learn about packet inspection across various network layers, regardless of the CNI used. Gain insights into how eBPF can be leveraged to debug Kubernetes networking problems effectively. Examine real-life examples of networking challenges and their solutions using eBPF-based approaches. No prior knowledge of kernel internals or deep networking understanding is required to benefit from this presentation, making it accessible to DevOps professionals operating Kubernetes clusters.
