Building a Multi-node Environment with Cilium and K3s in Twenty Minutes or Less
In this guide, we will walk through the steps required to build a multi-node Kubernetes cluster on your local workstation or laptop using K3s and Cilium. Then we'll show how you can use Hubble to inspect traffic in the cluster and visualize data exposed by the superpowers of eBPF and Cilium. We will also show you how to restrict the flow of traffic between applications. Finally, we will see how Cilium and Hubble can provide detailed information to help you solve problems related to compliance and regulations.

Debugging and Monitoring DNS issues in Kubernetes
DNS is a common cause for outages and incidents in Kubernetes clusters. For real-world stories, swing by Kubernetes Failure Stories. How do you debug and troubleshoot DNS issues? How do you know a problem is related to DNS? This guide provides a step by step tutorial on how to systematically troubleshoot DNS issues in Kubernetes clusters. We will be using [Hubble] to identify and inspect DNS issues as well as set up monitoring so we can locate DNS issues early on to react even before incidents occur.
