Packages containerOS toolkit

containerOS (cOS) 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.

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 few 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
