## What it is
A collection of copy-paste-ready YAML recipes and tutorials for Kubernetes Network Policies, covering common traffic restriction scenarios. It serves as both documentation and a learning resource for securing pod-to-pod networking.

## Use cases
- deny all traffic to an application in kubernetes
- restrict pod traffic between namespaces
- learn kubernetes network policies with examples
- find sample networkpolicy yaml to copy
- secure kubernetes cluster networking
- allow only specific pods to reach a service

## When to choose
- you need ready-made NetworkPolicy YAML for common scenarios
- you are learning how Kubernetes NetworkPolicies work
- you want practical recipes for isolating namespaces or pods

## When to avoid
- you need a tool that generates or enforces policies automatically
- your cluster's CNI plugin does not support NetworkPolicies
- you need layer 7 (HTTP-level) traffic control

## Facets
- artifact type: learning-resource
- maturity: active
- function: security, networking, documentation
- domain: networking, security, developer-tools
- platform: cloud, self-hosted
- tags: network-policy, yaml-examples, copy-paste-recipes, k8s-security, kubernetes
