Enforce Policy as Code

Implement declarative policy enforcement using OPA Gatekeeper or Kyverno for Kubernetes resource validation and mutation.

When to Use

• Enforce organizational standards for resource configuration (labels, annotations, limits)
• Prevent security misconfigurations (privileged containers, host namespaces, insecure images)
• Ensure compliance requirements are met before resources deployed
• Standardize resource naming conventions and metadata
• Implement automated remediation through mutation policies
• Audit existing cluster resources against policies without blocking
• Integrate policy validation into CI/CD pipelines for shift-left approach

Inputs

• Required: Kubernetes cluster with admin access
• Required: Choice of policy engine (OPA Gatekeeper or Kyverno)
• Required: List of policies to enforce (security, compliance, operational)
