Do you really understand how Kubernetes Services work? I didn't. My knowledge stopped at "there are some magic rules doing some magic load balancing". But I finally took a leap and learned how iptables work and how Kubernetes uses them in ClusterIP services. I thought others might find it this useful, so I've put together a recap that dives deep into the inner workings of Kubernetes Services. This recap unravels the complexities step by step, from the Linux kernel's networking stack and the Netfilter framework to the role of kube-proxy and the intricacies of iptables chains, rules, targets, and actions. You'll gain insights into how traffic is intercepted, how destination IPs are rewritten using DNAT, and how packets seamlessly flow from nodes to pods, bypassing intermediate processes. This recap is based on Gulcan's article, which is way more detailed.
