Fuel is open source initiative which provides great automation and flexibility for: * CentOS and Ubuntu provisioning on bare metal servers * Disk partitioning, including software RAIDs. Support of hardware RAIDs is in the roadmap * Complex network configurations, including VLANs, GRE and bonding * Network verification (VLANs, DHCP) before deployment * Automated deployment of OpenStack components and Ceph * Health Check - a set of short-running tests to ensure functionality of deployed environment

● 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
