Kubernetes Networking 101 - Randy Abernethy, RX-M LLC

Kubernetes Networking 101 will introduce attendees to the world of network communications in a hands on Cloud Native setting. This talk delivers a high level but completely practical end to end look at service communications within and without a Kubernetes cluster. Attendees will see how the many facets of Kubernetes networking come together to enable powerful communications solutions first hand. The tutorial begins with the simplest types of service communications, using Kubernetes services, DNS (CoreDNS) and CNI plugins (Cilium) to facilitate interprocess communications and load balancing. The tutorial builds additional scenarios on this base, including ingress (Emissary/Envoy), NodePort / HostPort features, load balancing (Metal-lb) and finally a short look at service mesh functionality (Linkerd). Upon completion of this tutorial, attendees will have a clear understanding of the Kubernetes communications possibilities and pointers to next steps in the learning journey.

This was a fantastic comprehensive talk. Filled some the gaps in my understanding for sure.

Although Kubernetes is "unopinionated", it does need to provide some guidelines or best practices, otherwise it is just a bag of tools dependent on the user's skill sets. By 1.23+, Kubernetes is still too difficult for most users, and this is telling.

Actually how many subnet is required to form k8s cluster? Got nodeip, clusterip, serviceip, podip. I seen for min single subnet does work but actually for production deployment how many subnet network is required (regardless the prefix).

This is what I was looking for. I haven't gotten far into the video, but hope this has info about metallb.🤞

Kubernetes eats it's own dog food.

Or Kubernetes eat it own shit.
