Building images

Both AutoSD and its downstream RHIVOS are sets of RPM binaries. You customize and build your own image, including your own applications as RPMs or container images.

OSBuild is the tool to build those images on CentOS Stream, Fedora, or RHEL hosts, with the option to build immutable images using OSTree.

Prerequisites

Before you build images, be aware of the following constraints:

• No cross-compilation: To build AArch64 or x86_64 images, you must run OSBuild on the respective systems. Some options for AArch64 hosting include Raspberry Pi 4 or QEMU on Linux or macOS. For more information, see Getting started on Linux or macOS.

• A subscribed RHEL system: To build RHEL images, you must have access to a subscribed RHEL system to access to the entitlements. RHEL images can only be built on subscribed RHEL systems.
