Learn about Red Hat Enterprise Linux and Insights image builders
Creating “golden images” of an operating system (OS) is a popular and recommended practice for deploying new systems to any environment; from your data center to the public cloud. They ensure rapid deployments that are maintainable and conform to your unique Standard Operating Environment (SOE) requirements. Red Hat Enterprise Linux (RHEL) provides two options to help you easily build customized RHEL OS images: RHEL image builder and Insights image builder.
What is RHEL image builder?
RHEL image builder is a feature that enables you to assemble customized operating system images for consistent provisioning and deployment across all environments, including physical systems, virtual machines, clouds, and more. This feature is a part of RHEL and can be installed on-premises. It includes both a Command Line Interface (CLI) as well as a graphical user interface within the RHEL web console. Additional instructions and documentation can be found in Composing a customized RHEL system image.
What is Insights image builder?
Red Hat Insights image builder is a hosted service implementation of the RHEL image builder located under Inventory->Images in Insights for RHEL of the Hybrid Cloud Console. Note that you can also enable Preview mode at the top to test new, pre-release functionality.
Insights image builder shares most of the same code base and functionality as the RHEL image builder. It provides a ready to use experience with no need to install your own dedicated build node. Additional instructions and documentation can be found in Deploying and managing RHEL systems in hybrid clouds.
Optimize RHEL for the open-hybrid enterprise
Included in your RHEL subscription, both RHEL and Insights image builders make it easy to consistently and repeatedly assemble RHEL optimized for the target platform. By default, it creates an equivalent of a “Minimal Install”, and includes any necessary packages as appropriate for the image type. You can also specify additional packages that you’d like to include in the image. More details of what is installed by default for each image type can be found in Chapter 4.9. Packages installed by RHEL image builder. You can also easily apply complex configurations such as industry standard security compliance profiles or include your own scripts to be run at initial startup.
