Kernel Gossip: What Linux and K8s Are Saying Behind Your Backplane - Nic Vermande

This talk unveils the hidden dialogue between Kubernetes and Linux, leveraging the superpowers of eBPF. The speaker explains the complexities of how Kubernetes schedules pods and triggers critical operations within the Linux kernel, including cgroups and namespaces. By reversing the flow of information, the session demonstrates real-time capture of kernel signals, using a lightweight Rust and eBPF observer to enhance infrastructure responsiveness to kernel truths. Attendees will gain insights into making kernel interactions visible, troubleshooting Kubernetes operations, and developing practical eBPF skills that can be applied across observability, security, and networking domains. The speaker, Nic Vermande, is a seasoned technologist with over 20 years in Cloud-Native technologies and Open Source Software, known for his engaging presentations at tech conferences worldwide.
