Introduction Kubernetes NetworkPolicies are API resources that define allowed ingress and egress traffic for pods. By default, Kubernetes networking is permissive: any pod can reach any other pod and many external endpoints. NetworkPolicies give you the specification for segmentation, but enforcement depends entirely on the CNI.
