ManageIQ for OpenStack by Tzu-Mainn Chen, Marek Aufart and Petr Blaho at ManageIQ Design Summit 2016

1. ManageIQ and OpenStack

2. Agenda
Introduction
Quick OpenStack TripleO Overview
OpenStack Cloud Provider
OpenStack Infrastructure Provider
Putting the OpenStack Providers Together
Future Work

3. Introduction - Our Team and Goals
Red Hat Team of seven engineers
Mix of ManageIQ and upstream Openstack backgrounds
ManageIQ Goals
Keep up with the latest OpenStack technologies
Close the gap with Horizon, the upstream GUI for OpenStack
Close gaps between OpenStack providers and other ManageIQ providers

4. OpenStack TripleO - OpenStack-on-OpenStack
Use OpenStack to deploy OpenStack
Undercloud
(Deployment Cloud)
Nova
Ironic
Heat
Glance
Overcloud (Workload Cloud)
Controller Node
Keystone

Nova API
Compute Node 1

Swift Proxy
RabbitMQ

5. OpenStack Cloud Provider - Object Store
Uses OpenStack Swift API to list object stores (OpenStack Swift containers)
View contents of each object store

6. OpenStack Cloud Provider - Volume Management
Uses Cinder v2 API
Provides volume list and detail views
Actions
Add/Delete/Attach/De-attach
Add volume during provisioning

7. OpenStack Cloud Provider - ManageIQ Reports
Uses data sourced from Ironic and Ceilometer to integrate with established
ManageIQ reports
Right-size Recommendation
Capacity Planning Report

8. OpenStack Cloud Provider - Ceilometer Events
Alternative to monitoring AMQP message bus
Uses public OpenStack APIs instead of depending on AMQP ports being open
Required changes in both upstream OpenStack and ManageIQ

9. OpenStack Cloud Provider - Other
SSH Key Management
Instance Re-Configure

10. OpenStack Infra Provider - Inventory
Node (Ironic - Bare Metal Provisioning)
Roles (Heat - Orchestration)
Running Services (Host Fleecing)

11. OpenStack Infra Provider - Management
Scale up number of compute nodes
Scale down number of compute nodes
… but duplicates TripleO logic (we’ll get back to this)

12. OpenStack Infra Provider - Metrics
Sourced from Ceilometer

13. OpenStack Infra Provider - Auto-Scaling
Side project done a year ago for fun
Remarkably easy

14. OpenStack Cloud + Infra Provider - Configuration
Cloud provider specifies infrastructure provider

15. OpenStack Cloud + Infra Provider - Migration
VM Live Migration
Host Evacuate

16. Future Work
General
Dashboard views
Topology views
Cloud
Segregation (Host Aggregates, Regions, Availability Zones)
Close Horizon gaps
Cinder volume backup/restore
Additional provisioning workflows
Tenant management
Host Aggregate management

17. Future Work - TripleO and Mistral
Mistral workflows to encapsulate TripleO business logic
Can access upstream TripleO logic with single API call
Scaling, deployment, updates, upgrades become extremely easy to expose in
