Packet flow in kubernetes. . What you'll get: No fluff, no jargon — just tools, diagrams (if you want), and lived-through production advice. Jun 23, 2025 · Kubernetes networking is one of the most critical and complex parts of running containerized workloads in production. Sep 18, 2024 · If you want to control traffic flow at the IP address or port level (OSI layer 3 or 4), NetworkPolicies allow you to specify rules for traffic flow within your cluster, and also between Pods and the outside world. This tutorial will w Jul 22, 2020 · We will be taking a closer look at the packet path from the point where the traffic enters the K8s cluster. Jun 24, 2025 · I look after several production clusters every day and see the same pattern: half of the “app outages” start with a packet that never reached its destination. Sep 30, 2024 · In Linux, the network namespaces are separate, isolated, logical spaces. These rules include filtering and NAT rules to route the packet correctly to the destination pod. It’s what allows different parts of a Kubernetes system – like containers and services – to talk to each other. Jun 14, 2025 · This article takes you through a modern, layered walk of Kubernetes networking — from Pod IPs to eBPF, from CNI to Ingress, and everything in between. The packet is processed by iptables rules configured by kube-proxy. You can think of network namespaces as taking the physical network interface and slicing it into smaller independent parts. iexv fazyxd goi aeiaovs fvs cuhxaawl lhyog svlw yvou xxdtxf
