What are the projects involved or related?

The bootc tooling and project are the nexus of a lot of the functionality that enable containers to be used to deploy Linux systems:

• bootc documentation
• bootc on Github

Obviously all the usual container tooling should be used to build images, such as Podman, Docker, Quay, Docker Hub, and so on. The Image Builder project can be used to convert bootable container images to disk images when necessary:

• bootc-image-builder on Github

The composefs, overlayfs, fs-verity and UKI provide the basic technology to pursue the trust chain work.

• composefs on Github
• overlayfs documentation
• fs-verity documentation
• UKI specification

Podman Desktop can be used to get started with bootable container images:

• Podman Desktop bootc extension

Linux distributions like Bluefin and more broadly the Universal Blue project are pursuing this today.

• Project Bluefin
• Universal Blue

There are proposals in Fedora to implement bootable container images as an image mode for the operating system.
