- 4. What is PTG? PTG = Project Team Gathering
- 5. What is PTG?
- 6. What is PTG?
- 9. Highlight topic Skip-release topic → Fast forward upgrade topic. Ø Purpose of this topic: to help operators upgrade Openstack system as fast as possible. Ø Plan for future: § Modify “support-upgrade” tag and “supports-accessible-upgrades” tag. § Create a outline docs about FFU. § Continue to discuss this topic in Sydney summit.
- 11. Highlight topic Special Interest Group (SIG) Ø How to expand our outreach to various groups § Working Group (WG) -> Special Interest Group (SIG) § API developer-focused -> SDK developers and users
- 13. Things done in Pike Neutron: Ø “Support for zero-downtime upgrades from Ocata (a.k.a. rolling upgrades) Ø haproxy is now used instead of the neutron namespace proxy agent for reduced memory usage on the server running the metadata proxy Ø Improvements to stability/performance, QoS, DVR Ø Support for quota usage amounts in quota API Ø Support for individual DNS domains set per Neutron port Ø Support for per-network MTU overrides Ø Support for user-defined tags on all standard Neutron resources”
- 14. Things done in Pike Cinder: Ø Having a “revert to snapshot” feature Ø Supporting extending a volume that is in-use. Ø Added volume group replication support
- 15. Things done in Pike Nova: Ø Moved on to Cell v2 § Timeline: nova-network deprecated in Newton. Cellsv1 only runs under nova-network in Ocata. Cellsv2 required in Ocata. Multi-cell cellsv2 available in Pike. Ø Introduced Placement § In Pike, didn’t properly handle migrations § Got some fixes in Pike, should do better solution in Queens
- 16. Things done in Pike Ironic: Ø Boot from Cinder volumes Ø Rolling upgrade between releases Ø Driver composition reform (dynamic driver model) Ø Redfish hardware type § Features implemented in a vendor-agnostic fashion
- 17. Things done in Pike Kolla: Ø Docker images for about 50 OpenStack services Ø Ansible roles for about 50 OpenStack services Ø Kolla-kubernetes nearly has compute kit
- 19. Things continue in Queens Nova: Ø Cell v2 § Drop nova-network and Cell v1 § Efficiently listing instances in a multi-cell deployment § Efficiently cross-cell queries Ø Placement § Traits: qualitative part of resources (besides the quantitative part) § Nested resource providers • PCI devices can have Physical Functions (PFs), each of which can supply a number of Virtual Functions (VFs) • May not be complete in Queens § Generic Device Management § Separate Placement out into its own service
- 20. Things continue Queens Neutron: Ø Improve Neutron documentation for simpler deployments Ø Can delete neutron CLI at the end of R cycle Ø Security group logging
- 21. Things continue in Queens Cinder: Ø Show resource's total count info in list APIs [1] Ø Report backend state in service list Ø Apply encryption and qos per volume [1] https://review.openstack.org/#/c/505101/ [2] https://blueprints.launchpad.net/cinder/+spec/generic-backup-implementation
- 22. Things continue in Queens Ironic: Ø Reference architecture guide Ø Deploy steps Ø Networking features § Routed network support (close to completion) § Neutron event processing Ø Ironic-inspector HA Ø Some others: node tags, ipa api versioning, rescue mode, e-tags, ... Ø Openstack goals § Python3 § Switching to uWSGI § Splitting away the tempest plugin
- 23. Things continue in Queens Glance: Ø Deprecated Registry API v1, Image API v1 Ø Multihash support for image https://etherpad.openstack.org/p/glance-queens-ptg-roadmap
- 24. Things continue in Queens Kolla: Ø General § Documentation rework § Ceph bumped to L Ø Kolla-ansible § devmode § Improve CI gating Ø Kolla-kubernetes Ø Kolla with TripleO joined forces § Healthcheck § CI jobs § Docker images
