Capítulo 1. Image Builder description
1.1. Introduction to Image Builder
You can use Image Builder to create customized system images of Red Hat Enterprise Linux, including system images prepared for deployment on cloud platforms. Image Builder automatically handles details of setup for each output type and is thus easier to use and faster to work with than manual methods of image creation. You can access Image Builder functionality through a command-line interface in the
composer-cli tool, or a graphical user interface in the RHEL 8 web console.
As of Red Hat Enterprise Linux 8.3, the
osbuild-composer backend replaces
lorax-composer. The new service provides REST APIs for image building. As a result, users can benefit from a more reliable backend and more predictable output images.
Image Builder runs as a system service
osbuild-composer. You can interact with this service through two interfaces:
composer-clifor running commands in the terminal. This method is preferred.
