Introduction to Cilium - CNI Implementation for Kubernetes with eBPF

Dive into a comprehensive live tutorial on Cilium, an open-source CNI implementation for Kubernetes integrated with eBPF. Join host Rawkode and guest Ilya Dmitrichenko as they explore Cilium's installation, configuration, and troubleshooting. Learn about Container Networking Interface (CNI), Cilium's advantages, and practical demonstrations including the Star Wars demo and Hubble integration. Navigate through common challenges such as IPAM range issues and DNS configuration, while gaining insights into Cilium endpoints, CLI usage, and deployment strategies using both Quickstart and Helm methods. Experience real-time problem-solving and understand the intricacies of securing network connectivity in Linux container management platforms like Docker and Kubernetes using BPF technology.
