Mutual Authentication with Cilium

Introduced in Cilium 1.14 is support for a much-requested feature: mutual authentication. From its inception, we looked at delivering an optimal effortless user experience to achieve mutual authentication. The result is simple: add 2 lines of YAML to your Cilium Network Policy, and that’s it – your workload communication is now secured with a mutual TLS handshake. Try it in this new Star Wars-inspired lab!

Isovalent Enterprise for Cilium: Connectivity Visibility with Hubble

This lab provides an introduction to Isovalent Enterprise for Cilium capabilities related to connectivity observability. This track primarily focuses on Hubble Flow events that provide label-aware, DNS-aware, and API-aware visibility for network connectivity within a Kubernetes environment using Hubble CLI, Hubble UI and Hubble Timescape, which provides historical data for troubleshooting.

Isovalent Enterprise for Cilium: Security Visibility

In this scenario, we are going to simulate the exploitation of a nodejs application, with the attacker spawning a reverse shell inside of a container and moving laterally within the Kubernetes environment.   We will demonstrate how the combined Process and Network Event Data: identify the suspicious Late Process Execution tie the suspicious processes to a randomly generated External Domain Name trace the Lateral Movement and Data Exfiltration of the attacker post-exploit

Cilium Transparent Encryption with IPSec and WireGuard

Encryption is required for many compliance frameworks. Kubernetes doesn’t natively offer pod-to-pod encryption. To offer encryption capabilities, it’s often required to implement it directly into your applications or deploy a Service Mesh. Both options add complexity and operational headaches. Cilium actually provides two options to encrypt traffic between Cilium-managed endpoints: IPsec and WireGuard. In this lab, you will be installing and testing both features and will get to experience how easy it is to encrypt data in transit with Cilium.

Golden Signals with Hubble and Grafana

One of the most important thing when running applications in an environment like Kubernetes is to have good observability and deep insights. However, for many organizations it can be challenging to update existing applications to provide the observability you need. With Cilium, you can use the Hubble Layer 7 visibility functionality to get Prometheus metrics for your application without having to modify it at all. In this lab you will learn how Cilium can provide metrics for an existing application with and without tracing functionality, and how you can use Grafana dashboards provided by Cilium to gain insight into how your application is behaving.

Migrating from Flannel

Migrating to Cilium from another CNI is a very common task. But how do we minimize the impact during the migration? How do we ensure pods on the legacy CNI can still communicate to Cilium-managed during pods during the migration? How do we execute the migration safely, while avoiding a overly complex approach or using a separate tool such as Multus? With the use of the new Cilium CRD CiliumNodeConfig, running clusters can be migrated on a node-by-node basis, without disrupting existing traffic or requiring a complete cluster outage or rebuild. In this lab, you will migrate your cluster from an existing CNI to Cilium. While we use Flannel in this simple lab, you can leverage the same approach for other CNIs.

Cilium IPv6 Networking and Observability

Learn how simple IPv6 can be installed and operated with Cilium and Hubble. With Kubernetes’ IPv6 support improving in recent releases and Dual Stack Generally Available in Kubernetes 1.23, it’s time to learn about IPv6 on Kubernetes. You might be wondering “How on Earth am I going to be able to operate this?” Good news – you’re in the right place. This lab will walk you through how to deploy a IPv4/IPv6 Dual Stack Kubernetes cluster and install Cilium and Hubble to benefit from their networking and observability capabilities. In particular, visibility of IPv6 flows is absolutely essential. IPv6’s slow adoption is primarily caused by fears it would be hard to operate and manage. As you will see, a tool such as Hubble will help operators visualize and understand their IPv6 network better.
