November is turning out to be the Month of BGP on my blog. Keeping in line with that theme, let’s watch Stuart Charlton explain the Calico plugin (which can use BGP to advertise the container networking prefixes to the outside world) in the Kubernetes Networking Deep Dive webinar.

Ready for more Kubernetes details? How about Container Networking Interface (CNI) described by Stuart Charlton as part of Kubernetes Networking Deep Dive webinar?

Notes:

• You REALLY SHOULD watch Kubernetes SDN architecture and Sample Kubernetes SDN Implementations videos first
• The video (and a large portion of Kubernetes Networking Deep Dive webinar) is available with Free ipSpace.net Subscription.

It’s time for another Kubernetes video. After Stuart Charlton explained the Kubernetes SDN architecture, he described architectural approaches of Kubernetes SDN implementations, using Flannel as a sample implementation.

Stuart Charlton started the Kubernetes Networking Deep Dive webinar with an overview of basic concepts including the networking model and services. After covering the fundamentals, it was time for The Real Stuff: Container Networking Interface, starting with an overview of Kubernetes SDN architecture.

While the pundits keeps telling me Docker is dead (looking at its documentation I would say they’re right) and Kubernetes it the way to go (yay!), some people still have to deal with Docker networking, and at least some of them found the Docker Networking Deep Dive webinar useful. Here’s a recent review:

You can scroll over internet pages as long as you can, you will rarely find this kind of specialized knowledge. This is the next level in term of knowledge about Docker.

If you belong to the “Kubernetes will rule the world” camp, we have you covered as well: Stuart Charlton created a phenomenal Kubernetes Networking Deep Dive webinar (approximately half of it is already accessible with free subscription).

After a brief introduction of Kubernetes service and an overview of services types, Stuart Charlton added the last missing bit: how do you expose Kubernetes services to external clients.

Kubernetes services are like networking standards: there are so many to choose from. In his brief introduction to Kubernetes service types, Stuart Charlton listed six of them, and I’m positive there are more. That’s what you get when you’re trying to reinvent every network load balancing method known to mankind ;)

After completing the discussion of basic Kubernetes networking with a typical inter-pod traffic scenario, Stuart Charlton tackled another confusing topic: an overview of what Kubernetes services are.

Stuart Charlton did his best to explain the concept of pods in the Kubernetes Networking Deep Dive webinar, but we were still a bit confused. Next step: let’s talk about typical inter-pod traffic scenario.

Pods are a basic building block of any Kubernetes-based deployment… but what exactly are they and how are they related to Kubernetes networking? Stuart Charlton unraveled that mystery in the Understanding Pods video (part of Kubernetes Networking Deep Dive webinar)

After describing the Kubernetes architecture in the introductory part of the excellent Kubernetes Networking Deep Dive webinar, Stuart Charlton focused on what matters most to networking engineers: Kubernetes networking model.

Yesterday I mentioned the giant glob of complexity called Kubernetes (see also more nuanced take on the topic). If you want to slowly unravel it, Kubernetes Architecture video from the excellent Kubernetes Networking Deep Dive webinar by Stuart Charlton is a pretty good starting point.

After answering the “why should I care about Kubernetes?” question, Stuart Charlton explained the Kubernetes principles you should keep in mind if you want to have a chance of understanding what’s going on.

Here’s what one of the engineers watching Stuart Charlton’s Kubernetes webinar wrote about it:

I was listening to an excellent container networking podcast and enjoyed it thoroughly until the guest said something along the lines of:

With Kubernetes networking policy, you no longer have to be a networking expert to do container network security.

That’s not even wrong. You didn’t have to be a networking expert to write traffic filtering rules for ages.
