Kubernetes networking enables containerized workloads to communicate through a flat network model where each pod gets a unique IP address without NAT. The tutorial covers core concepts including CNI plugins (Flannel, Calico, Cilium), kube-proxy for service load balancing, CoreDNS for service discovery, and network policies for security. It explains pod-to-pod, pod-to-service, and external-to-service communication patterns, along with practical troubleshooting techniques for common networking issues like unreachable pods and services.
