Understanding Kubernetes Networking Part 3: Calico Kubernetes CNI Provider in depth.

In this video, I will comprehensively cover Calico CNI for Kubernetes. I will start with an overview of the Container Network Interface (CNI) architecture before proceeding to cover Calico in depth. I will also cover some fundamental technologies such as Border Gateway Protocol (BGP) and IP-in-IP encapsulation protocol which Calico uses behind the scenes. And last but not least, I will also discuss various Calico network options such as non-overlay (TOR and single L2), and cross-subnet options.

In the video, I made a reference to another course of mine for creating a new cluster on CentOS, however after that video was published, Red Hat announced CentOS 8 will be the last supported version so I don't recommend using CentOS.

Keywords: CNI, Flannel, BGP, IPIP, IP in IP

Great video! These series have helped demystified Kubernetes POD networking. The breakdown of how Calico works was really brilliant with animation and network capture. Well done!

[geetikabatra]

This is great! For so many years every book and folks used to refer switch as a layer 2 device, nobody explained it in terms of subnets. Now I am actually able to distinguish between Data layer anf Network layer.

This series is insanely good! Love the detail in the slides and the live demos.

wow..wow.... how did i miss this video for all these days ..amazing explanation.. way better than all the paid courses combined ...please do more videos

[bommuu]

This is one of the best networking in Kubernetes explanation. Really learned and enjoyed. Thanks for the videos.

[guents]

Great job again! You are one of the few people on youtube who does k8s videos and actually knows what they're talking about :D

[alexs]

I finally understand how BGP works, thanks for explaining!

[robertscott]

Outstanding presentation! Thank you for using the KISS method!

[rakra]

You deserve kudos for this simple but in-depth video. Spectacular job.

[khemrajdhondge]

What great efforts taken to explain this details!!! Great breakdown with all steps

[ramprasad_v]

Good explanation & I learnt a lot. Thanks

[Banjour]

Best 1 hour I ever spent studying something on Youtube. Thanks for explaining Calico so wonderfully - especially the parts about felix, bird, and IPIP mode. Could you do a small one for VXLAN mode and its benefits? Thanks!

[fgngejw]

watching 10th video of yours - superb details and simplicity in explaining complex topics. thanks

[seyyidahmedlahmer]

The best networking lectures ever! I really appreciate what you are doing! thanks a lot

[mikhailgorbov]

There are few such deep videos. Thanks for your hard work.

[rougearlequin]

I love the detailed information of the traffic captures. Great tutorial!

[mailsirshendu]

Exceptional content... Loved the details you have put in... Kudos!!!

[javierpena]

Excellent video has helped improve my understanding of this topic a lot. Thank you for your work!

[tothetech]

Wonderful tutorial, thanks a lot for valuable information
