 +===== Discussion =====
 +
 +An Image is an identifiable [[public:99_annexes:annex-b-terms-and-definitions:a:artifact|Artifact]] that packages software, configuration, files, metadata, and other content used to instantiate a computing subject.
 +
 +An Image may be used to instantiate:
 +
 +  * A virtual machine
 +  * A containerized workload
 +  * A computing device
 +  * A platform component
 +  * A runtime environment
 +  * Another deployable computing subject
 +
 +An Image may contain:
 +
 +  * Executable software
 +  * Operating-system content
 +  * Runtime libraries
 +  * Application files
 +  * Configuration files
 +  * Startup instructions
 +  * Security controls
 +  * Dependency information
 +  * Identifying metadata
 +  * One or more [[public:99_annexes:annex-b-terms-and-definitions:i:image_layer|Image Layers]]
 +
 +An Image may participate in:
 +
 +  * Image building
 +  * Image composition
 +  * Image signing
 +  * Image verification
 +  * Compliance assessment
 +  * Image promotion
 +  * Repository publication
 +  * [[public:99_annexes:annex-b-terms-and-definitions:o:offline_transfer|Offline Transfer]]
 +  * Deployment
 +  * Replacement
 +  * [[public:99_annexes:annex-b-terms-and-definitions:r:retirement|Retirement]]
 +
 +An Image differs from an instance:
 +
 +  * An Image is the Artifact used to instantiate a computing subject
 +  * An instance is a realized computing subject created from an Image
 +
 +Multiple instances may originate from the same Image while maintaining separate runtime state.
 +
 +An Image differs from an [[public:99_annexes:annex-b-terms-and-definitions:i:image_layer|Image Layer]]:
 +
 +  * An Image is the complete Artifact used to instantiate a computing subject
 +  * An Image Layer is an identifiable unit of content incorporated into an Image
 +
 +Specializations of Image include:
 +
 +  * [[public:99_annexes:annex-b-terms-and-definitions:m:machine_image|Machine Image]]
 +  * [[public:99_annexes:annex-b-terms-and-definitions:c:container_image|Container Image]]

 +
 +===== Source =====

 +Dido Solutions, Inc. and Jackrabbit Consulting, Inc.
 +
 +===== Note =====
 +
 +In Crucible documentation, **Image** refers to a deployable computing Artifact rather than a photograph, diagram, graphical representation, or filesystem backup unless the surrounding text explicitly establishes another meaning.
 +
 +An Image may be identified by:
 +
 +  * A name
 +  * A tag
 +  * A content digest
 +  * A [[public:99_annexes:annex-b-terms-and-definitions:r:revision|Revision]] identifier
 +  * A release identifier
 +  * A combination of identifiers
 +
 +An Image does not by itself establish that the Image is:
 +
 +  * Approved
 +  * Signed
 +  * Verified
 +  * Free from vulnerabilities
 +  * Compliant with an applicable [[public:99_annexes:annex-b-terms-and-definitions:b:baseline|Baseline]]
 +  * Authorized for deployment
 +  * Compatible with a target platform
 +  * Suitable for a specified purpose
 +
 +Separate requirements govern those determinations.
 +
 +The term does not prescribe a particular image format, build tool, repository, runtime, virtualization platform, container platform, operating system, or [[public:99_annexes:annex-b-terms-and-definitions:p:provider_implementation|Provider Implementation]].
 +
 +===== Example =====
 +
 +[[public:99_annexes:annex-b-terms-and-definitions:c:crucible|Crucible]] builds an Image containing controlled software, configuration, runtime files, security controls, and identifying metadata. A deployment process later uses the Image to instantiate a virtual machine or containerized workload.
