Red Hat Enterprise Linux (RHEL)

Go up to Terms and Definitions

Discussion

Red Hat Enterprise Linux (RHEL) is an enterprise Linux operating-system distribution produced and supported by Red Hat.

RHEL provides an operating-system foundation for physical machines, virtual machines, cloud instances, containers, development environments, and production platforms. Organizations commonly use RHEL in enterprise, regulated, and high-assurance environments that require controlled releases, security updates, lifecycle support, and vendor support.

A number following RHEL identifies the applicable major version family. For example, RHEL 9 identifies the Red Hat Enterprise Linux major version 9 family. A further number may identify a minor release within that family.

Within Crucible, RHEL may provide the operating system for a Base Image, Guest Image, Hardened Image, or Capability Image.

Generalized from Red Hat product terminology and specialized for the Crucible architecture and operational model.

Note

The acronym RHEL identifies Red Hat Enterprise Linux. A number following the acronym identifies the major version family.

For example:

RHEL 9 identifies major version 9RHEL 9.4 identifies minor release 9.4 within the RHEL 9 familyA reference to RHEL 9 does not necessarily identify a specific minor release. A reproducible build should identify and record the exact release and associated installation media or package sources used.

Example

A Crucible Image Baseline identifies RHEL 9 as the operating-system family and pins the specific installation medium, package repositories, and source revisions used to produce the Machine Image.
