Learn OPA-REGO with Real Code Examples

OPA runs as a sidecar, daemon, or service

Policies written in Rego are loaded into OPA

Applications query OPA via REST API or SDK

OPA evaluates policies using input JSON data

Decision logs capture outcomes for audit and compliance

Application -> JSON input -> OPA -> Policy evaluation -> Decision
