We are glad to present this week's priorities and subteam report for Ironic. As usual, this is pulled directly from the Ironic whiteboard[0] and formatted.

High Priorities

Neutron event processing (vdrok, vsaienk0, sambetts)
- status as of 27 Sep 2017:
    - spec at https://review.openstack.org/343684, ready for reviews, replies from authors
    - WIP code at https://review.openstack.org/440778

Routed network support (sambetts, vsaienk0, bfournie, hjensas)
- status as of 29 Jan 2018:
    - The first couple of patches merged ... we need some more landing before we have something of use. (e.g this one to actually use the agent_db data https://review.openstack.org/#/c/521838/ )
    - Need reviews ... https://review.openstack.org/#/q/topic:bug/1658964+(status:open+OR+status:merged)
    - With neutron fixed; patch below; the dsvm job seems stable.
    - Fix for neutron issue https://review.openstack.org/#/c/534449/ (Merged).
    - hjensas taken over as main contributor from sambetts
    - There is challenges with integration to Placement due to the way the integration was done in neutron.
    Neutron will create a resource provider for network segments in Placement, then it creates an os-aggregate
    in Nova for the segment, adds nova compute hosts to this aggregate. Ironic nodes cannot be added to host-aggregates.
    I (hjensas) had a short discussion with neutron devs (mlavalle) on the issue:
    There are patches in Nova to add support for ironic nodes in host-aggregates:
        - https://review.openstack.org/#/c/526753/ allow compute nodes to be associated with host agg
        - https://review.openstack.org/#/c/529135/ (Spec)
    - Patches:
        - https://review.openstack.org/456235 Add baremetal neutron agent (Merged)
        - https://review.openstack.org/#/c/533707/ start_flag = True, only first time, or conf change (Merged)
        - https://review.openstack.org/521838 Switch from MechanismDriver to SimpleAgentMechanismDriverBase
        - https://review.openstack.org/#/c/536040/ Flat networks use node.uuid when binding ports.
        - https://review.openstack.org/#/c/537353 Add documentation for baremetal mech
        - https://review.openstack.org/#/c/532349/7 Add support to bind type vlan networks
        - https://review.openstack.org/524709 Make the agent distributed using hashring and notifications
    - CI Patches:
        - https://review.openstack.org/#/c/531275/ Devstack - use neutron segments (routed provider networks)
        - https://review.openstack.org/#/c/531637/ Wait for ironic-neutron-agent to report state
        - https://review.openstack.org/#/c/530117/ Devstack - Add ironic-neutron-agent
        - https://review.openstack.org/#/c/530409/ Add dsvm job
        - https://review.openstack.org/#/c/392959/ Rework Ironic devstack baremetal network simulation

Rescue mode (rloo, stendulker, aparnav)
- Status as on 29 Jan 2018
    - spec: http://specs.openstack.org/openstack/ironic-specs/specs/approved/implement-rescue-mode.html
    - code: https://review.openstack.org/#/q/topic:bug/1526449+status:open
    - ironic side:
        - All patches are up-to-date, being actively reviewed and updated
        - Tempest tests based on standalone ironic is WIP.
        - Tempest tests with nova is also WIP: https://review.openstack.org/#/c/528699/
        - Add documentation for rescue interface https://review.openstack.org/419606
        - Follow-up for agent rescue implementation https://review.openstack.org/538252
    - nova side:
        - https://blueprints.launchpad.net/nova/+spec/ironic-rescue-mode: approved for Queens; waiting for ironic part to be done first. Queens feature freeze is week of Jan 22. (TheJulia) Nova has indicated that this is deferred until Rocky.
        - To get the nova patch merged, we need:
            - release new python-ironicclient
            - update ironicclient version in upper-constraints (this patch will be posted automatically)
            - update ironicclient version in global-requirement (this patch needs to be posted manually)
        - code patch: https://review.openstack.org/#/c/416487/
        - There is a FFE for this. However, the client has been released without the rescue code, so this won't all land. (Can't land anything that needs the client code).
        - CI is needed for nova part to land
            - tiendc is working for CI

Clean up deploy interfaces (vdrok)
- status as of 9 Jan 2017:
    - patch https://review.openstack.org/524433 ready for reviews

Zuul v3 jobs in-tree (sambetts, derekh, jlvillal, rloo)
- etherpad tracking zuul v3 -> intree: https://etherpad.openstack.org/p/ironic-zuulv3-intree-tracking
- cleaning up/centralizing job descriptions (eg 'irrelevant-files'): DONE
- Next TODO is to convert jobs on master, to proper ansible. NOT a high priority though.
    - (pas-ha) DNM experimental patch with "devstack-tempest" as base job https://review.openstack.org/#/c/520167/

Graphical console interface (pas-ha, vdrok, rpioso)
- status as of 8 Jan 2017:
    - spec on review: https://review.openstack.org/#/c/306074/
    - there is nova part here, which has to be approved too
    - dtantsur is worried by absence of progress here
        - (TheJulia) I think for rocky, it might be worth making it a prime focus, or making it a background goal.

BIOS config framework (dtantsur, yolanda, rpioso)
- status as of 8 Jan 2017:
    - spec under active review: https://review.openstack.org/#/c/496481/

OpenStack Priorities

Python 3.5 compatibility (Nisha, Ankit)
- Topic: https://review.openstack.org/#/q/topic:goal-python35+NOT+project:openstack/governance+NOT+project:openstack/releases
    - this include all projects, not only ironic
    - please tag all reviews with topic "goal-python35"
- TODO submit the python3 job for IPA
- for ironic and ironic-inspector job enabled by disabling swift as swift is still lacking py3.5 support.
- anupn to update the python3 job to build tinyipa with python3
    - (anupn): Talked with swift folks and there is a bug upstream opened  https://review.openstack.org/#/c/401397 for py3 support in swift. But this is not on their priority
    - Right now patch pass all gate jobs except agent_- drivers.
- we need to make the ironic job voting eventually. but we need to check that nova, glance and neutron already have voting python 3 jobs, otherwise they may break us.
    - nova seems to have python 3 jobs voting, here are our patches:
        - ironic https://review.openstack.org/#/c/531398/
        - ironic-inspector https://review.openstack.org/#/c/531400/ MERGED

Deploying with Apache and WSGI in CI (pas-ha, vsaienk0)
- ironic is mostly finished
    - (pas-ha) needs to be rewritten for uWSGI, patches on review:
        - https://review.openstack.org/#/c/507011/ +A
        - https://review.openstack.org/#/c/507067 Needs revision
- inspector is TODO and depends on https://review.openstack.org/#/q/topic:bug/1525218
    - may be delayed to after Queens, as the HA work seems to take a different direction

Split away the tempest plugin (jlvillal)
- https://etherpad.openstack.org/p/ironic-tempest-plugin-migration
- Current (8-Jan-2018) (jlvillal): All projects now using tempest plugin code from openstack/ironic-tempest-plugin
    - Need to remove plugin code from master branch of openstack/ironic and openstack/ironic-inspector
        - Plugin code will NOT be removed from the stable branches of openstack/ironic and openstack/ironic-inspector
        - (jlvillal) 3rd Party CI has had over 3 weeks to prepare for removal. We should now move forward
    - README, setup.cfg and docs cleanup: https://review.openstack.org/#/c/529538/ MERGED
    - ironic-tempest-plugin 1.0.0 released


Inspector (dtantsur)
- trying to flip dsvm-discovery to use the new dnsmasq pxe filter and failing because of bash :Dhttps://review.openstack.org/#/c/525685/6/devstack/plugin.sh@202
- follow-ups being merged/reviewed; working on state consistency enhancements https://review.openstack.org/#/c/510928/ too (HA demo follow-up)

Bifrost (TheJulia)
- Also seems a recent authentication change in keystoneauth1 has broken processing of the clouds.yaml files, i.e. `openstack` command does not work.
    - TheJulia will try to look at this this week.


DRAC (rpioso, dtantsur)
- Dell Ironic CI is being rebuilt, its back and running now (10/17/2017)

OneView (ricardoas, nicodemos, gmonteiro)
- Re-submitting reverted patches for migration from python-oneviewclient to python-hpOneView + python-ilorest-library [MERGED]
    - Check weekly priorities for most import patch to review

Cisco UCS (sambetts)
- Currently rebuilding third party CI from the ground up after it bit the dust
- Patches for updating the UCS python SDKs are in the works and should be posted soon

Until next week,
