Is this skill compatible with existing Kubernetes tools?

Yes, it follows standard Kubernetes CRD patterns and is compatible with Helm, kubectl, and GitOps workflows.

Can I test policies without breaking my cluster?

Yes, Gatekeeper supports a 'dryrun' enforcement action which allows you to see policy violations in logs and status fields without actually blocking any requests.

What is OPA Gatekeeper?

OPA Gatekeeper is a specialized admission controller for Kubernetes that uses the Open Policy Agent (OPA) to enforce fine-grained policies on cluster resources.

How do ConstraintTemplates and Constraints differ?

ConstraintTemplates define the logic of a policy using Rego, while Constraints are the specific instances of those templates that apply parameters to specific resources.

セキュリティとテスト

Enforces Kubernetes admission policies using OPA Gatekeeper and Rego to secure cluster resources and ensure compliance.

This skill enables automated policy-as-code enforcement across Kubernetes clusters by implementing Open Policy Agent (OPA) Gatekeeper. It provides a structured approach to creating ConstraintTemplates and Constraints for validating resource requests, blocking privileged containers, restricting image registries, and enforcing resource limits. By integrating these controls at the admission level, security teams can ensure that all workloads adhere to organizational standards and regulatory frameworks like NIST CSF 2.0 before they are even deployed.
