Policy-as-Code Template Library

When to Use This Skill

48 production-ready policies for Kubernetes security and governance. Reduce the Rego learning curve. Copy, customize, deploy.

Template Library Overview

This library contains 28 Kyverno policies and 20 OPA/Gatekeeper constraint templates covering pod security, image validation, RBAC, resource governance, network security, mutation, and generation. Each template includes complete YAML/Rego, customization variables, validation commands, and real-world use cases.

Implementation

Deploy in Audit Mode First

Always start with audit (Kyverno) or dryrun (OPA) mode. Monitor violations for 48 hours before switching to enforcement. Existing workloads may violate policies.

Kyverno Quick Start (5 minutes)

See examples.md for detailed code examples.

OPA/Gatekeeper Quick Start (10 minutes)

See examples.md for detailed code examples.

Comparison

Choose the right policy engine for your team:

Feature	Kyverno	OPA/Gatekeeper
Policies	28 (validation, mutation, generation)	20 (validation only)
Language	YAML + JMESPath	Rego (Go-like DSL)
Learning Curve	< 1 hour	4-8 hours
Best For	Kubernetes-native teams, fast adoption	Multi-platform policies, complex logic
Mutation	✅ Native support	❌ Validation only
Generation	✅ Auto-create resources	❌ Validation only

See Decision Guide → for detailed comparison and recommended starter paths.
