Image Promotion

Go up to Terms and Definitions

Image Promotion is the controlled transition of a Machine Image from one lifecycle status, usage scope, or operating context to another.

The transition may authorize the image for broader testing, staging, production deployment, a different organizational domain, or another approved environment.

Image Promotion evaluates the applicable build records, test results, compliance findings, integrity information, provenance, approvals, and target-context requirements before changing the image status.

The process changes the image's permitted use or governance status. It does not necessarily modify the image content.

Generalized from release management, artefact management, software delivery, configuration management, and machine-image governance usage and specialized for the Crucible architecture and operational model.

Image Promotion differs from copying or uploading an image. A transfer changes location or availability, while Image Promotion changes the image’s authorized status or permitted use.

A promoted image should retain the identity, integrity, information, evidence, and provenance associated with the evaluated image.

After a Red Hat Enterprise Linux (RHEL) p Hardened Image passes integration testing, compliance assessment, signature verification, and governance review, the organization promotes it from the test catalog to the production-approved catalog.
