The Kubernetes Proxy NG a new design of kube-proxy aimed at

• allowing Kubernetes business logic to evolve with minimal to no impact on backend implementations,
• improving scalability,
• improving the ability of integrate 3rd party environments,
• being library-oriented to allow packaging logic at distributor's will,
• provide gRPC endpoints for lean integration, extensibility and observability.

The project will provide multiple components, with the core being the API watcher that will serve the global and node-specific sets of objects.

• More context can be found in the project's KEP.
• The meeting agenda and notes are here https://docs.google.com/document/d/1yW3AUp5rYDLYCAtZc6e4zeLbP5HPLXdvuEFeVESOTic/edit#
• See you friday at 8:30 PST / 11:30 EST !!!

The KPNG group is small but dedicated, because this is a hard project. Your first commit might take weeks or months, especially if you're new to the kube-proxy or to K8s networking. However, we will pair with people wanting to join and make an impact. We pair program every friday at our meetings, and also, informally at other times as well.

Our goal is to:

• make the kube proxy fun to work on and easy to understand
• make the kube proxy extensible from a command line and backend perspective
• learn as much as we can about k8s service networking, and build an upstream community around it

And that goes for people working on KPNG especially. So don't hesitate to join us, but just be ready for alot of work and low level troubleshooting.

There are many ways to get started, but here's a good set of guidelines.

In particular, you should be able to differentiate:

• CNI providers (i.e. calico, antrea, cillium, and so on)
• Service Proxies (i.e. kube-proxy, AntreaProxy, CilliumProxy, various service-mesh's, and so on)
• LoadBalancers (i.e. serviceType=LoadBalancer)

There are about 20 or 30 great youtube videos about Kubernetes networking and the Kube proxy that you can easily search for and study. There are also several books about Kubernetes networking and basic Kubernetes architecture.

The existing K8s codebase https://github.com/kubernetes/kubernetes/tree/master/pkg/proxy, has a complex, monolithic, battle-hardened proxy. Read through it and try to put the peices together, so you understand the overall problem space that KPNG solves.

Now that you've seen the basics, you're ready to join the KPNG group meetings and find a project to get involved with!
