Kyverno is a Kubernetes-native policy engine that uses standard YAML and CRDs to implement Policy-as-Code for cluster governance. It supports four core policy types: Validate, Mutate, Generate, and Cleanup. Practical examples show how to protect critical CRD resources from accidental deletion, auto-mutate Pod security contexts to enforce runAsNonRoot, and auto-generate NetworkPolicies on namespace creation. The post also covers integration with AI Agents via MCP/Skills to create an intelligent security governance loop, where AI enhances policy authoring and Kyverno enforces guardrails on AI workloads themselves. Kyverno's advantages over alternatives include no need to learn Rego, a rich community policy library, and built-in compliance reporting aligned with Kubernetes Policy Working Group specs.
