bootc: Bootable Containers for the OS

by Shriira Press

A practical, in-depth guide to bootc (bootable containers), the project that lets you build, deploy, and transactionally update an operating system using standard OCI container images. Learn how bootc brings container practices to the OS: the OS update problem, the ostree/composefs architecture, building bootable container images, day-1 install and disk/cloud images, transactional updates and rollback (A/B deployments), the /usr-/etc-/var state split, immutability and supply-chain security, and operating image-based Linux fleets at scale.
