What exactly happens when network traffic inside a Kubernetes cluster goes from one pod to another -- or, why doesn't it when you think it should? Which host interfaces will you see Kubernetes network addresses on, and what else on the host can you look at to help you troubleshoot network issues with your workloads?

Maybe most importantly, *how* can you figure out what's wrong with any of it? If you're new to Kubernetes, or just want a refresher and update on some of the networking basics, Joe Thompson will show you how OS-native tools and simple techniques (that you might already use) can help you bridge the gap between what you already know about networks and how Kubernetes does networking.
