Ratify is a CNCF Sandbox open-source verification framework for container images and other supply chain artifacts in Kubernetes environments. It enables policy-driven artifact ratification by coordinating any number of pluggable verifiers (signatures, SBOMs, scan results, attestations) against a given policy, integrating with Kubernetes admission webhooks via the Gatekeeper policy engine. Ratify is developed by the ratify-project GitHub organization (originally a Microsoft open-source project), written in Go, and distributed as a CLI tool, Go library, and Kubernetes admission webhook server. It supports OCI-compliant artifact stores including Azure Container Registry, Amazon ECR, and Docker Hub. Ratify exposes an internal HTTP verification API (v2alpha1) consumed by its webhook server but does not publish a public-facing REST API or OpenAPI specification.
