Kubernetes has become the standard for deploying containerized systems. But with great flexibility comes great risk, without proper policies, clusters can easily become mismanaged, insecure, and difficult to maintain over time. Today, we invited Khun Tarn, Platform Services Manager, to share how Policy-as-Code helps define and enforce policies as code: automated, auditable, and collaborative across Dev, Platform, and Security teams.
Here are some of the most popular Policy-as-Code tools you should have on your radar:
- OPA Gatekeeper- Rego-based, enforces complex policies, supports audit.
- Kyverno- YAML-friendly, easy for DevOps & Platform engineers, EKS-ready.
- Kubewarden- WASM-powered, secure, multi-tenant & multi-cluster capable.
- K-Rail- Lightweight, minimal dependencies, ideal for targeted controls.
- Cloud Custodian- Event-driven, cross-cloud & Kubernetes compliance automation.
Adopting Policy-as-Code can significantly improve how you manage Kubernetes:
- Systematic reviews with version-controlled, reusable policies
- Fewer misconfigurations and communication gaps
- Consistent, enforced standards across teams
- Stronger security from the very first deployment
- Easier upgrades & maintenance as Kubernetes evolves
Policy-as-Code isn’t just about enforcement, it’s a smarter way to manage your infrastructure: faster, safer, and more reliable for the long run.
