About
This course provides a detailed introduction to Cilium, a cutting-edge networking plugin for Kubernetes that leverages eBPF technology for scalability and security. Over 24 hours of instruction, participants will learn how to use Cilium to connect, observe, and secure cloud-native environments effectively.
Introduction to Cilium
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.
Prerequisite
- Linux concepts and command line – We recommend our “Linux System Administration” Course
- Kubernetes Knowledge – We recommend undergoing “Kubernetes for System Administrators” Course
- Knowledge of Git.
- For hands-on lab exercises, access to a public cloud provider, or VirtualBox on your machine is needed.
Target audiences
- This course is designed for application developers, systems operators, and security professionals with an interest in learning how to use Cilium to better connect, observe, and secure Kubernetes. Learners should be familiar with basic Kubernetes concepts, and Kubernetes operations.
