tomevault-io 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) ordryrun(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.
