elemental-toolkit

elemental-toolkit is a toolkit to build, ship and maintain cloud-init driven Linux derivatives based on container images with a common featureset - allows container images to be bootable in VMs, baremetals, embedded devices, and much more.

It is designed to reduce the maintenance surface, with a flexible approach to provide upgrades from container registries. It is cloud-init driven and also designed to be adaptive-first, allowing easily to build changes on top.

Documentation is available at https://rancher.github.io/elemental-toolkit/docs

Design goals

• A Manifest for container-based OS. It contains just the common bits to make a container image bootable and to be upgraded from, with little customization on top
• Immutable-first, but with a flexible layout
• Cloud-init driven
• Based on systemd
• Built and upgraded from containers - It is a single image OS!
• OTA updates
• Easy to customize
• Cryptographically verified
