Network Policy

A Kubernetes NetworkPolicy is a namespaced resource that controls how groups of Pods are allowed to communicate with each other and with other network endpoints. By defining ingress and/or egress rules that match Pods via label selectors, it provides fine-grained, declarative network segmentation inside the cluster, helping operators restrict unintended traffic and harden workloads. If no NetworkPolicy targets a Pod, that Pod is non-isolated and can both send and receive traffic to and from any source.

Pod​

A NetworkPolicy selects one or more Pods (in the same namespace) through podSelector rules; therefore, each referenced Pod can be linked to the NetworkPolicy that governs its allowed ingress and egress traffic.
