Bootable Containers - bootc

Redhat have introduced, as a preview, using image mode for RHEL to build, deploy, and manage operating systems. This "image mode" is based on bootable containers.

• https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html/using_image_mode_for_rhel_to_build_deploy_and_manage_operating_systems/managing-rhel-bootable-images_using-image-mode-for-rhel-to-build-deploy-and-manage-operating-systems#switching-the-container-image-reference_managing-rhel-bootable-images

This repo is my notes whilst experimenting with bootc for managing my Linux fleet with a cloud native workflow.

Ideas I am interested in:

• Can I use a Containerfile (Dockerfile) as the source of truth for all image types - containers, local VMs, bare metal, AWS ami's etc ?
• Does this mean no more Packer ?
• cloud native development workflow and tooling for managing a fleet of Linux machines (bare metal, VMs or containers)
• Air gapped updates
• Over the air updates
• easy Roll backs
• supply chain security for bare metal, VMs and containers

Docs

I am collecting a bunch of notes in the docs directory.
There is a collection of tasks being collected using Just.
Just is a task runner similar to make, but designed to run project-specific commands, it is not a build system.
Intro to Just if you need some more info.
