Kubernetes Network Policy Recipes

Kubernetes Network Policy Recipes is a practical, example-driven repository offering ready-to-use Kubernetes NetworkPolicy manifests and patterns for real application networking scenarios. Rather than just listing theoretical API specs, it groups recipes that implement common intent-based policies — such as isolating namespaces, restricting cross-pod traffic, enabling ingress from specific services, and locking down egress to only necessary endpoints — so users can pick and apply what they need. These recipes help secure Kubernetes clusters by ensuring that pods communicate only with allowed peers, reduce attack surfaces, and enforce least-privilege connectivity at the network layer. The recipes scale from simple “deny all traffic by default” policies to more advanced micro-segmentation patterns for multi-tier apps (frontend/backends) and platform-level isolation for CI/CD systems or service meshes.
