Image Catalog

Go up to Terms and Definitions

An Image Catalog is a controlled collection of Image Records used to identify, locate, compare, select, and govern available Machine Images.

The catalog may record image identities, versions, operating systems, processor architectures, capabilities, compliance postures, source revisions, provider identifiers, integrity information, lifecycle status, and associated evidence.

An Image Catalog supports image selection by allowing deployment and composition processes to compare image requirements with the characteristics of available images.

Within Crucible, the Image Catalog may connect a built image with its provider-specific realizations, controlled inputs, compliance results, and Provenance.

Generalized from artifact catalog, image registry, configuration management, cloud-image management, and software inventory usage and specialized for the Crucible architecture and operational model.

An Image Catalog records information about Machine Images. It does not necessarily store the image content itself.

An Image Catalog differs from a container registry or package repository because its primary purpose is to describe and govern Machine Images and their realizations.

An Image Catalog records a hardened Red Hat Enterprise Linux (RHEL) 9 Kubernetes image, its processor architecture, source revisions, compliance results, cryptographic digest, OCI image identifier, and approved lifecycle status.
