ABOUT THIS COURSE

Skip About this course

When you deploy Kubernetes, you need to install a networking plug-in
implementing the Container Networking Interface (CNI) to provide connectivity
between workloads. Cilium is a popular and widely-deployed CNI solution that is
now the default across many Kubernetes distributions and cloud provider
offerings.

In this course, you will learn the basics of Cilium and how it can be used to
connect, observe, and secure Kubernetes clusters. We will start by reviewing
Kubernetes container networking and its challenges. We’ll move on to discussing
the architecture of Cilium and how it uses eBPF to address those challenges.
eBPF is a Linux technology that allows changing the kernel’s behavior through
dynamically loaded custom programs. We’ll provide an overview of what eBPF is
and how Cilium uses it to benefit cloud native networking.

We will provide a step-by-step guide for installing and setting up Cilium as
your CNI. Once installed, we will show how to configure basic network policies
to secure your network and how we can use Hubble to observe these network flows.
Finally, we will discuss some of the commonly used features of Cilium, such as
support for FQDN-based and L7 protocol-aware network policies, 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.

AT A GLANCE

 * Institution: LinuxFoundationX
 * Subject: Computer Science
 * Level: Introductory
 * Prerequisites:
   
   Learners should have some familiarity with Kubernetes operations and have
   basic experience using the kubectl tool. The course assumes that students are
   comfortable with basic Kubernetes concepts such as pods, nodes, services and
   clusters. To make the most of this course, we highly recommend the free
   Introduction to Kubernetes (LFS158x) course available on edX, which covers
   these prerequisites.
   
   It is sufficient to have used minikube or kind to deploy a demo microservice
   application in a development cluster environment.
   
   The hands-on exercises require a Kubernetes cluster pre-provisioned without a
   CNI plugin. The cluster hosts must be using a linux kernel with socket load
   balancing support (kernel versions v4.19.57, v5.1.16, v5.2.0 or more recent).
   The learners’ primary system should have the helm, kubectl and curl commands
   available.
   
   All exercises have been tested using local development clusters based on Kind
   (v0.17.0) and minikube (v1.26.1) as well as Azure’s AKS service. You can find
   instructions for setting up a kubernetes cluster that meets the requirements
   in the Cilium.io documentation.
