Build-Pipelines for Operating System Artifacts

OSBuild is a pipeline-based build system for operating system artifacts. It defines a universal pipeline description and a build system to execute them, producing artifacts like operating system images, working towards an image build pipeline that is more comprehensible, reproducible, and extendable.

See the osbuild(1) man-page for details on how to run osbuild, the definition of the pipeline description, and more.



Please refer to the developer guide to learn about our workflow, code style and more.


The requirements for this project are:

  • bubblewrap >= 0.4.0
  • python >= 3.6

Additionally, the built-in stages require:

  • bash >= 5.0
  • coreutils >= 8.31
  • curl >= 7.68
  • qemu-img >= 4.2.0
  • rpm >= 4.15
  • tar >= 1.32
  • util-linux >= 235
  • skopeo

At build-time, the following software is required:

  • python-docutils >= 0.13
  • pkg-config >= 0.29

Testing requires additional software:

  • pytest


Installing osbuild requires to not only install the osbuild module, but also additional artifacts such as tools (i.e: osbuild-mpp) sources, stages, schemas and SELinux policies.

For this reason, doing an installation from source is not trivial and the easier way to install it is to create the set of RPMs that contain all these components.

This can be done with the rpm make target, i.e:

make rpm

A set of RPMs will be created in the ./rpmbuild/RPMS/noarch/ directory and can be installed in the system using the distribution package manager, i.e:

sudo dnf install ./rpmbuild/RPMS/noarch/*.rpm
