Automotive SIG repositories

Automotive SIG members have several repositories where they can find or contribute to automotive-specific code and RPM packages. For more information about contributing to these repositories, see Contributing packages.

Automotive SIG repositories

The Automotive SIG git repository offers additional or divergent packages that are tailored for automotive use cases and compatible with AutoSD and CentOS Stream. It has the same structure as the CentOS Stream rpms and src namespaces.

All SIG members can request packages to be distributed through these repositories, provided they meet CentOS requirements for SIG. The Automotive SIG recommends using different branches with clear names for your work in the Automotive SIG repository.

Automotive SIG community members can use and contribute to projects within Automotive SIG repositories to develop and test public proofs of concept for CentOS automotive variants, like AutoSD, automotive software infrastructure, and automotive hardware reference platforms.

Not all innovation attempts succeed. These Automotive SIG packages might be works in progress that eventually land in AutoSD, or they might be experimental work that remains outside of AutoSD, such as research and development concepts or integration ideas.

AutoSD repositories

Because AutoSD is the public, in-development version of the Red Hat Automotive product, direct access to the AutoSD repositories is restricted to Red Hat employees. However, anyone in the community can propose changes the AutoSD repositories. Change proposals for AutoSD can take many forms, you can submit a change request using one or more of the following methods:

AutoSD nightly RPM package composes

The AutoSD nightly repo stores all AutoSD RPM packages composed by Red Hat Automotive SIG members.

Red Hat Automotive SIG members use configurations of the distribution compose tool Pungi, stored in the AutoSD repository of PipeX, to compose Automotive SIG source code and RPM packages into the AutoSD builds using the Koji build system. PipeX is a Red Hat Edge continuous improvement / continuous development (CI/CD) workflow system built upon repositories for tooling and package-level pipelines-as-code using GitLab CI.

For more information about the CentOS Build System (CBS) tags you need to contribute packages to AutoSD, see AutoSD CBS tags.

Downloading AutoSD nightly RPM package composes

The latest version of AutoSD is available at https://autosd.sig.centos.org. You do not need to download the entire AutoSD repository unless you intend to build offline using customized manifests. All sample image manifests require a remote connection to the main CentOS repositories.

Prerequisites

  • wget
  • At least 52 GB of available disk space, which changes frequently as the SIG enhances the aarch64, x86_64, and noarch package set

Procedure

  1. Optional: Install wget:

    sudo dnf wget

  2. Download a local copy of the repository using wget or your preferred download method:

    $ wget --recursive --no-parent -Rc "index.html*" \
'https://autosd.sig.centos.org/AutoSD-9/nightly/repos/AutoSD/compose/AutoSD/'

CentOS Stream git repositories

The CentOS Stream repository stores the CentOS Stream source code and RPM packages used for Automotive and AutoSD in the following namespaces:

rpms
The CentOS Stream dist-git is the dedicated git repository for each CentOS package. It contains the spec files and patches used to build CentOS Stream RPMs, and it has a sources file that points to a specific file that the build system retrieves from the lookaside-cache.
src
The CentOS Stream source-git is the source code git repository for CentOS Stream 9 and 10 where the packages files as well as the untarballed source code is stored. It has automation that automatically syncs from the source-git to the dist-git. However, it does not store every CentOS stream package, only those that have opted into this model.

You can browse Automotive and AutoSD packages available from CentOS Stream in the the CentOS Stream mirror. For more information, see the CentOS Stream Quick start guide for new contributors.

Fedora and EPEL repositories

The Fedora community works on a project called Extra Packages for Enterprise Linux (EPEL). RPM packages that are part of EPEL are compatible with CentOS Stream, AutoSD, RHEL, and Red Hat In-Vehicle OS.

You can browse available Fedora RPM packages at Fedora Package Sources, or browse Fedora-based builds from the Automotive SIG on the Fedora build system, copr.

For examples of how you might use EPEL packages in AutoSD, see AutoSD non-sample images.
