====== Image Requirement ====== [[dido:99_annexes:annex-b-terms-and-definitions:start|Go up to Terms and Definitions]] ===== Discussion ===== An Image Requirement is a machine-processable statement that identifies a characteristic a [[dido:99_annexes:annex-b-terms-and-definitions:m:machine_image|Machine Image]] must possess for a defined build, deployment, workload, or operating context. An Image Requirement may identify an operating-system family and version, processor architecture, capability, security posture, compliance profile, source revision, integrity value, provider compatibility, lifecycle status, or other selection criterion. Infrastructure can declare Image Requirements without identifying a specific Machine Image. An image-selection process compares those requirements with the characteristics recorded for available images. Within Crucible, Image Requirements support separation between an [[dido:99_annexes:annex-b-terms-and-definitions:i:infrastructure_baseline|Infrastructure Baseline]] and the Machine Images that may satisfy it. ===== Definition ===== //machine-processable statement that identifies a characteristic a [[dido:99_annexes:annex-b-terms-and-definitions:m:machine_image|machine image]] must possess for a defined build, deployment, workload, or operating context// ===== Source ===== Generalized from requirements engineering, machine-image management, infrastructure automation, and artifact-selection usage and specialized for the Crucible architecture and operational model. ===== Note ===== An Image Requirement identifies a required characteristic rather than a specific image unless the requirement explicitly identifies one. Several Machine Images may satisfy the same set of Image Requirements. A single Machine Image may satisfy the requirements of several deployments. ===== Example ===== An Infrastructure Baseline declares Image Requirements for a [[dido:99_annexes:annex-b-terms-and-definitions:r:rhel]] 9 AArch64 image with Kubernetes capability, an approved STIG compliance profile, and a verified integrity value. ---- © 2026 Dido Solutions, Inc. and Jackrabbit Consulting, Inc.
