TripleO: OpenStack on OpenStack
summary
TripleO uses OpenStack to deploy and upgrade OpenStack by booting nova bare-metal driver machines from prebuilt images, orchestrating relationships with heat orchestration templates, and applying config with os-collect-config / os-refresh-config / os-apply-config. The workflow builds disk images with Disk Image Builder, tests them in CI/CD clouds (the infrastructure spins up whole clouds repeatedly), and does rolling upgrades so production stays available; a full bare-metal node can go from powered off to serving in about 6 minutes using image-based provisioning.
