Tutorial: Communication Is Key -- Understanding Kubernetes Networking - Jeff Poole, Vivint Smart Home
Networking in Kubernetes has several aspects, including DNS, iptables, routing, software bridges, IP assignment, network policies, etc. While the practices for understanding the network were fairly easy to translate from physical servers to virtual machines, the level of complexity increases greatly when moving to containers in Kubernetes. This tutorial will explain several of the networking concepts used in Kubernetes with accompanying lab exercises in a virtualized environment so that participants will become comfortable looking under the hood at how a Kubernetes cluster is working (or not working, as the case may be). The material will be designed for people comfortable with SSH, bash, kubectl, and basic networking concepts, and will fill in the more advanced networking knowledge as the tutorial progresses. Please have Vagrant + VirtualBox installed to run the labs locally.

This is still one of the best video regarding networking

[@user-zw8uq1rj9m]

The best tutorial EVER. He really knows what he is doing

[@kostia2271]

this is one of the best videos about k8s network internals I've ever seen

[@annablendermann]

It took me nearly half a day to get through this tutorial! Very complex -- I guess that proves that I'm a networking beginner haha. This cleared up a lot of questions for me as well.

[@eddymazembomavungu8949]

Thanks Jeff. Very informative. I have been looking for these detailed explanations for so long... Great work!!!

[@aleksandarkostic3312]

Great lecture, but not aimed at absolute beginners. It assumes you have quite a good understanding of networking in general.

[@robertjmccabe]

Very nice. I'd love to see more of these low-level demos.

[@MaciejKonigsman]

It was excellent introduction to K8s networking. Thanks for that and for sharing scripts to setup K3s on containers simulating nodes. Exactly what I was looking for some time.
