Kubernetes network policies allow you to control network access to and from Pods. Network policies are namespaced resources and allow you to specify ingress (allowed incoming traffic) and egress (allowed outgoing traffic) rules. You define rules that select what Pods, namespaces, or IP address ranges the policy applies to.
