The document outlines the features and architecture of 'Fuel', a control plane for managing data centers, detailing its components, user interfaces, and additional functionalities. It highlights processes such as hardware discovery, configuration management, and OpenStack deployment. The roadmap includes resources for obtaining and building 'Fuel', as well as development processes and support channels.

● Resources & Development processes
Agenda

3. Fuel targets a position to become a control plane of
your Data Center
● Hardware Discovery
● Switches configuration [to be implemented]
● Network Verification
● OS provisioning on bare metal
● Deployment of OpenStack and beyond
● Post-deployment checks of OpenStack
What is Fuel?

4. Manual steps to setup an environment:
● Hardware planning
● Network configuration
How it works now (high level)

5. Manual steps to setup an environment:
● Hardware planning
● Network configuration
● [Live demo] Installation of Fuel Master node
● [Automated] Hardware discovery process

7. User Experience: UI (Live Demo)

8. User Experience: CLI (Live Demo)
● Covers everything we can do via UI
● Allows even more

9. Components: Nailgun

10. ● Written on Python
● Exposes internal data via REST API
● Concentrates up to 90% of deployment logic
● Transforms user input (UI, CLI) into deployment
data (JSON)
● Keeps tasks status and all information in DB
● Uses SQLAlchemy, Alembic for DB access and
migrations
Components: Nailgun

11. Components: Naily & Astute

12. ● Naily consumes messages sent by Nailgun
● Naily & Astute are both written in Ruby
● Astute uses MCollective RPC
● Has bindings to provisioning
● Tracks progress of deployment, provisioning
● Supports operations (adding/removing nodes)
● Small in comparison with Nailgun
Components: Naily & Astute

13. Components: OSTF (Health Check)

14. Architecture: bigger picture

15. ● Health Check
● Network Checker
○ DHCP
○ VLANs
● Diagnostic Snapshot
● Logs collection & calculation of operations
progress
● [In development] Master node upgrade
capabilities
Additional Functions

16. ● Core OpenStack components in HA fashion
○ nova-network & Neutron
○ Ceilometer
● Savanna (Hadoop on top of OpenStack)
● Murano (Windows DCs on top of OpenStack)
● Ceph
What Fuel already deploys?

17. ● Fuel Master node upgrades
● Patching & Upgrade of OpenStack
● Replacement of Cobbler by Ironic
