Introduction to Cilium (LFS146) Course Overview

The course teaches the basics of Cilium and how it is used to connect, observe, and secure Kubernetes clusters, starting with the container networking challenges motivating the creation of Cilium, followed by the Cilium architecture and how it uses eBPF to address those challenges. The course also provides a step-by-step guide for installing and setting up Cilium as your CNI is included, enabling you to learn how to configure network policies to secure a network and how to use Hubble to observe network flows. Finally, the course provides hands-on experience using some of Cilium’s most popular features, such as support for L7 protocol-aware network policies, transparent encryption, and cluster mesh networking. By the end of this course, you will understand how Cilium and Hubble work and how they can be used to connect, observe, and secure your cloud native environments.
