Building a custom AutoSD image

The AutoSD image-building process centers on three main components:

• Custom manifests
• Automotive Image Builder
• OSTree

A custom manifest is a YAML file that defines an AutoSD image. This file specifies everything to be included in the built OS image, from core OS components to user-specific applications, drivers, and security settings.

Automotive Image Builder (AIB) builds an OS image with the options specified in the manifest. AIB handles all required steps, from resolving dependencies to packaging the final image in various formats.

AutoSD images for immutable systems are built using OSTree, a Git-like system for managing and deploying OS images. This approach provides significant advantages for automotive systems, which demand reliability and security.

AutoSD is the public preview of the Red Hat In-Vehicle OS product and contains all of the technology and tools necessary to run a mixed-criticality workload on that safety certified product. The documentation on this page presents the technology underlying and available in the product, but all safety requirements and documents are not covered here and are available only to Red Hat In-Vehicle OS customers. These safety documents impose some limitations and additional activities necessary for safety workloads.
