Project Mu uses containers to build on Linux. These containers come with all of the tools expected for CI and virtual platform pipelines and local development. Containers can be pulled. For more details see the mu_devops packages page.
The Mu Ubuntu container provides the following layers. Ubuntu-24 is the recommended container image because it best aligns with existing development flows and provides tools needed to cross compile both kernel and user mode components needed in Mu.
Ubuntu-22 is the previous Ubuntu container image used in Mu CI from May 2023 until February 2025. It is still available for use, but is not recommended for new projects and other CI dependencies and worfklows may not be supported with it.
It will be deprecated soon. Users should migrate to Ubuntu-24 as soon as possible.
