Continuous Lifecycle: Enhance Your Compliance and Governance With Policy-Based CI/CD
0 likes•169 views
This document discusses using Open Policy Agent (OPA) to enhance compliance and governance in CI/CD pipelines. It introduces OPA as a general-purpose policy engine that uses a declarative policy language to decouple application logic from policy decisions. The document explains how OPA works, including its Rego policy language and built-in functions. It provides examples of using OPA for tasks like validating Kubernetes manifests and Terraform configuration changes.
