This article explains Kubernetes service discovery by first covering essential network concepts, then detailing how Services, DNS, Endpoints, and kube-proxy work together to provide stable, load‑balanced communication between dynamic Pods in a cluster.
This article explains the Kubernetes pod network concept, describing how each pod receives a unique IP, how intra‑node and inter‑node pod communication works, and the role of the infra container and network bridges in enabling seamless IP addressing across the cluster.
This article walks through the complete path of an HTTP request in a GKE Kubernetes cluster, explaining the role of the cloud load balancer, Service and ReplicaSet resources, kube-proxy operation modes, iptables rules, pod networking, and security considerations.
This article explains how Kubernetes provides stable service discovery by using a flat pod network, Service objects with immutable front‑ends and dynamic back‑ends, DNS registration, Endpoints, and kube‑proxy iptables/IPVS rules to route traffic from virtual ClusterIP addresses to healthy pods.
