[requirements] Issues while trying to bump-up ovsdbapp requirement for stable/queens
by Maciej Jozefczyk 17 Sep '19

17 Sep '19

Hello, I'm trying to bump-up ovsdbapp requirement in networking-ovn [0] from 0.8.0 [1] to 0.10.4 [2]. Those two are in the same stable/queens release and we need that change to merge some serious performance improvements to stable/queens. Unfortunately the requirements-check jobs fails on this change [3] with: Requirement for package ovsdbapp : Requirement(package=u'ovsdbapp', location='', specifiers='>=0.10.4', markers=u'', comment=u'# Apache-2.0', extras=frozenset([])) does not match openstack/requirements value : set([Requirement(package='ovsdbapp', location='', specifiers='>=0.8.0', markers='', comment='# Apache-2.0', extras=frozenset([]))]) The only place where >=0.8.0 is set is global-requirements [4]. Do we need to bump up it also there, even the upper-requirements bot proposal [5] has been merged? It is string match? I proposed a change to bump it in global-requirements [6]. Thanks, Maciej [0] https://review.opendev.org/#/c/681562/ [1] https://github.com/openstack/ovsdbapp/releases/tag/0.8.0 [2] https://github.com/openstack/ovsdbapp/releases/tag/0.10.4 [3] https://bb8048f0749367929365-38c02a6f4c2535c3f3f9bfdb5440d261.ssl.cf1.rackc… [4] https://github.com/openstack/requirements/blob/stable/queens/global-require… [5] https://review.opendev.org/#/c/682323 [6] https://review.opendev.org/#/c/682588 -- Best regards, Maciej Józefczyk

[os-win][requirements] FFE requested for os-win
by Lucian Petrut 17 Sep '19

17 Sep '19

Hi, I’d like to request a FFE for os-win. One important bug fix has missed the train (4.3.1) release, for which reason we’d need to have a subsequent one. The bug in question prevents Nova from starting after host reboots when using the Hyper-V driver on recent Windows Server 2019 builds. Thanks, Lucian Petrut

[oslo] Stepping down from core reviewer
by ChangBo Guo 17 Sep '19

17 Sep '19

Hi folks, I no longer have the time to contribute to Oslo in a meaningful way in past few months, due to the company internal stuff, and would like to step down from core reviewer. It was an honor to be one of the great team since 4 years ago. I still work on OpenStack, just have no enough time to focus on Oslo. I hope have more time to contribute again in the future :-) All the best! -- ChangBo Guo(gcb)

[all] stable/ocata gate failure
by Ghanshyam Mann 17 Sep '19

17 Sep '19

Hello Everyone, If you have noticed that stable/ocata gate is blocked where 'legacy-tempest-dsvm-neutron-full/-*' job is failing due to the latest Tempest changes. Tempest started the JSON schema strict validation for Volume APIs which caught the failure or you can say Tempest master cannot be used in Ocata testing. More details- https://bugs.launchpad.net/tempest/+bug/1843762 As per the Tempest stable branch testing policy[1], Tempst does not support the stable/ocata (which is EM )in the current development cycle. Current supported stable branches by Tempest are Queens, Rocky, Stein and Train-on-going. We can keep using Tempest master on EM stable/branches as long as it run successfully and if it start failing which is current case of stable/ocata then use Tempest tag to test that EM stable branch. To unblock the stable/ocata gate, I am trying to install the Tempest 20.0.0(compatible version for Ocata) in ocata gate - https://review.opendev.org/#/c/681950/ Fix is not working as of now (it still install Tempest master). I will debug that later (my current priority is for Train feature freeze). [1] https://docs.openstack.org/tempest/latest/stable_branch_support_policy.html -gmann

[all] Please do not bump openstackdocstheme minimum version if possible
by Thomas Goirand 17 Sep '19

17 Sep '19

Hi, The openstackdocstheme package in Debian is highly modified, because otherwise, building docs just fail. Namely, we have reverted commit d87aaca30f64502b3dd13cc1ddf46beec90fc015 because otherwise, the docs wouldn't build. Rebasing it is *very* annoying. So, it'd be nice if packages didn't depend on the very latest version of openstackdocstheme so we could keep version 1.20.0. I don't think it's that important to depend on the very latest version (please let me know if I'm wrong, and let me know why). Cheers, Thomas Goirand (zigo)

[kolla] Support Octavia for ubuntu binary on stable/rocky?
by Eddie Yen 17 Sep '19

17 Sep '19

Hi, I'm trying to install Octavia in Rocky release with Ubuntu binary distro. And found that there're no docker images for Ubuntu binary. Then I checked the Kolla dockerfile and found that it will not build the image since it's not support yet. But I found that the Ubuntu Cloud Archive Team has already putted Octavia packages into cloud repository [1]. Since some images built using from this PPA, I think it can support ubuntu binary in Rocky release. I tried put package code into Docker files and build, but it gave me an error message like below: ERROR:kolla.common.utils:octavia-api Failed with status: matched ERROR:kolla.common.utils:octavia-health-manager Failed with status: matched ERROR:kolla.common.utils:octavia-housekeeping Failed with status: matched ERROR:kolla.common.utils:octavia-worker Failed with status: matched So I think there's limit somewhere. How can I release it? Thanks, Eddie. [1] https://launchpad.net/~ubuntu-cloud-archive/+archive/ubuntu/rocky-staging

[dev] [glance] proposal for S3 store driver re-support as galnce_store backend
by Naohiro Sameshima 16 Sep '19

16 Sep '19

Hi all, I know that glance_store had supported S3 backend until version OpenStack Mitaka, and it has already been removed due to lack of maintainers [1][2]. I started refactoring the S3 driver to work with version OpenStack Stein and recently completed it. (e.g. Add Multi Store Support, Using the latest AWS SDK) So, it would be great if glance_store could support the S3 driver again. However, I'm not familiar with the procedure for that. Would it be possible to discuss this? Thanks, Naohiro [1] https://docs.openstack.org/releasenotes/glance/newton.html [2] https://opendev.org/openstack/glance_store/src/branch/master/releasenotes/n…

[placement] update 19-35
by Chris Dent 16 Sep '19

16 Sep '19

HTML: https://anticdent.org/placement-update-19-36.html Here's placement update 19-36. There won't be one next week, I will be away. Because of my forthcoming "less time available for OpenStack" I will also be stopping these updates at some point in the next month or so so I can focus the limited time I will have on reviewing and coding. There will be at least one more. # Most Important The big news this week is that after returning from a trip (that meant he was away during the nomination period) Tetsuro has stepped up to be the PTL for placement in Ussuri. Thanks very much to him for taking this up, I'm sure he will be excellent. We need to work on useful documentation for the features developed this cycle. I've also made a [now worklist](https://storyboard.openstack.org/#!/worklist/754) in StoryBoard to draw attention to placement project stories that are relevant to the next few weeks, making it easier to ignore those that are not relevant now, but may be later. # Stories/Bugs (Numbers in () are the change since the last pupdate.) There are 23 (-1) stories in [the placement group](https://storyboard.openstack.org/#!/project_group/placement). 0 (0) are [untagged](https://storyboard.openstack.org/#!/worklist/580). 5 (0) are [bugs](https://storyboard.openstack.org/#!/worklist/574). 4 (0) are [cleanups](https://storyboard.openstack.org/#!/worklist/575). 10 (-1) are [rfes](https://storyboard.openstack.org/#!/worklist/594). 5 (1) are [docs](https://storyboard.openstack.org/#!/worklist/637). If you're interested in helping out with placement, those stories are good places to look. * Placement related nova [bugs not yet in progress](https://goo.gl/TgiPXb) on launchpad: 17 (0). * Placement related nova [in progress bugs](https://goo.gl/vzGGDQ) on launchpad: 6 (0). # osc-placement * <https://review.opendev.org/666542> Add support for multiple member_of. There's been some useful discussion about how to achieve this, and a consensus has emerged on how to get the best results. # Main Themes ## Consumer Types Adding a type to consumers will allow them to be grouped for various purposes, including quota accounting. * <https://review.opendev.org/#/q/topic:bp/support-consumer-types> This has some good comments on it from melwitt. I'm going to be away next week, so if someone else would like to address them that would be great. If it is deemed fit to merge, we should, despite feature freeze passing, since we haven't had much churn lately. If it doesn't make it in Train, that's fine too. The goal is to have it ready for Nova in Ussuri as early as possible. ## Cleanup Cleanup is an overarching theme related to improving documentation, performance and the maintainability of the code. The changes we are making this cycle are fairly complex to use and are fairly complex to write, so it is good that we're going to have plenty of time to clean and clarify all these things. Performance related explorations continue: * <https://review.opendev.org/#/c/679385/> Refactor initialization of research context. This puts the code that might cause an exit earlier in the process so we can avoid useless work. One outcome of the performance work needs to be something like a _Deployment Considerations_ document to help people choose how to tweak their placement deployment to match their needs. The simple answer is use more web servers and more database servers, but that's often very wasteful. * <https://review.opendev.org/#/q/owner:"Chris+Dent+%253Ccdent%2540anticdent.org%253E"+topic:build-pdf-docs> These are the patches for meeting the build pdf docs goal for the various placement projects. # Other Placement Miscellaneous changes can be found in [the usual place](https://review.opendev.org/#/q/project:openstack/placement+status:op…. There are three [os-traits changes](https://review.opendev.org/#/q/project:openstack/os-traits+status:… being discussed. And two [os-resource-classes changes](https://review.opendev.org/#/q/project:openstack/os-resource-class…. The latter are docs-related. # Other Service Users New reviews are added to the end of the list. Reviews that haven't had attention in a long time (boo!) or have merged or approved (yay!) are removed. * <https://review.opendev.org/662229> helm: add placement chart * <https://review.opendev.org/670112> Nova: WIP: Add a placement audit command * <https://review.opendev.org/670696> tempest: Add placement API methods for testing routed provider nets * <https://review.opendev.org/#/q/topic:bp/cross-cell-resize> Nova: cross cell resize * <https://review.opendev.org/674524> Nova: Scheduler translate properties to traits * <https://review.opendev.org/623558> Nova: single pass instance info fetch in host manager * <https://review.opendev.org/#/q/topic:bp/provider-config-file> Nova: using provider config file for custom resource providers * <https://review.opendev.org/681955> Nova: clean up some lingering placement stuff * <https://review.opendev.org/664867> OSA: Add nova placement to placement migration * <https://review.opendev.org/681343> Charms: Disable nova placement API in Train * <https://review.opendev.org/#/q/topic:bug/1841481> Nova: stop using @safe_connect in report client # End 🐈 -- Chris Dent ٩◔̯◔۶ https://anticdent.org/ freenode: cdent

Dear Neutrinos, Many of you might have heard the Russel Boden's employer is changing his focus. As a consequence, Boden won't be able to continue leading our neutron-lib efforts. We want to thank you for the great job he has done over many cycles in advancing this sub-project. We are also looking for a volunteer to lead neutron-lib. Boden put together an etherpad with what needs to be done in the near future: https://etherpad.openstack.org/p/neutron-lib-volunteers-and-punch-list Regards Miguel

[cloudkitty] 13/09 meeting summary
by Luka Peschke 16 Sep '19

16 Sep '19

Hi everyone, This is the recap of the cloudkitty team IRC meeting that happened on 13/09. The logs can be found at [1]. All features patches we wanted to integrate have been merged for the feature freeze dealine. An experimental v2 storage driver for Elasticsearch has also been merged. Concerning the community goals: python3-first has been implemented early, however we're late for PDF docs generation, as we've got several issues when trying to generate PDF documentation, especially with tabs. A patch for cloudkitty has been proposed today [2]. Patches for the client and specs repos are to be done. They're our current top priority. From now on, the IRC meeting will be held twice every month, on the first and third monday at 14h UTC. This means that the next meeting will happen on october 7th. We plan to send a recap to this mailing list for each meeting. For the U cycle, we'd like to use storyboard a lot more. For now, it's been used for features and major bugs only, but we'll use it for every non-trivial patch from now on. Our temporary roadmap for U is the following: * Design and implement a new rating module. * Support time-based grouping in the /v2/summary endpoint. This would allow to easily create charts with cloudkitty's API. * [To be discussed] Stop differenciating "groupby" and "metadata" attributes, as these seem to be confusing for admins. * Port as many v1 API endpoints as possible to v2. Best regards, Luka Peschke (peschk_l) [1] http://eavesdrop.openstack.org/meetings/cloudkitty/2019/cloudkitty.2019-09-… [2] https://review.opendev.org/#/c/682364/

[keystone] Keystone Team Update - Week of 9 September 2019
by Colleen Murphy 14 Sep '19

14 Sep '19

# Keystone Team Update - Week of 9 September 2019 ## News ### Feature Freeze Status We have a number of policy changes and one spec implementation still crawling through the gate[1]. Since these have all been reviewed and approved we'll continue to babysit them until they have made it. Federated user attributes[2] and expiring group membership[3] are being deferred until next cycle due to insufficient reviews/incomplete implementation.

Execute a script on every object upload event (Swift+aodh)
by Anmar Salih 13 Sep '19

13 Sep '19

Hey all, Need help to configure swift and aodh. The idea is to trigger aodh alarm on very object upload event on swift. Once the alarm triggered, a small script should be executed. So the sequence of operations should be like this: 1- Object just uploaded to swift container 2- Alarm triggered by aodh 3- Once alarm triggered , execute python script. I am using Devstack Stein release installed on virtual box. Best regards. Anmar Salih

[all][PTL] Call for Cycle Highlights for Train
by Kendall Nelson 13 Sep '19

13 Sep '19

Hello Everyone! As you may or may not have read last week in the release update from Sean, its time to call out 'cycle-highlights' in your deliverables! As PTLs, you probably get many pings towards the end of every release cycle by various parties (marketing, management, journalists, etc) asking for highlights of what is new and what significant changes are coming in the new release. By putting them all in the same place it makes them easy to reference because they get compiled into a pretty website like this from Rocky[1] or this one for Stein[2]. We don't need a fully fledged marketing message, just a few highlights (3-4 ideally), from each project team. *The deadline for cycle highlights is the end of the R-5 week [3] on Sept 13th.* How To Reminder: ------------------------- Simply add them to the deliverables/train/$PROJECT.yaml in the openstack/releases repo similar to this: cycle-highlights: - Introduced new service to use unused host to mine bitcoin. The formatting options for this tag are the same as what you are probably used to with Reno release notes. Also, you can check on the formatting of the output by either running locally: tox -e docs And then checking the resulting doc/build/html/train/highlights.html file or the output of the build-openstack-sphinx-docs job under html/train/ highlights.html. Thanks :) -Kendall Nelson (diablo_rojo) [1] https://releases.openstack.org/rocky/highlights.html [2] https://releases.openstack.org/stein/highlights.html [3] https://releases.openstack.org/train/schedule.html <https://releases.openstack.org/train/schedule.html#t-cycle-highlights>

[release][freezer][karbor][kuryr][magnum][manila][monasca][neutron][senlin][tacker][winstackers] Missing releases for some deliverables
by Thierry Carrez 13 Sep '19

13 Sep '19

Hi everyone, Quick reminder that we'll need a release very soon for a number of deliverables following a cycle-with-intermediary release model but which have not done *any* release yet in the Train cycle: - freezer and freezer-web-ui - karbor and karbor-dashboard - kuryr-kubernetes - magnum-ui - manila-ui - monasca-agent, monasca-api, monasca-ceilometer, monasca-events-api, monasca-log-api, monasca-notification, monasca-persister and monasca-transform - networking-hyperv - neutron-fwaas-dashboard and neutron-vpnaas-dashboard - senlin-dashboard - tacker-horizon Those should be released ASAP, and in all cases before September 26th, so that we have a release to include in the final Train release. Thanks in advance, -- Thierry Carrez (ttx)

[release] Release countdown for week R-4, September 16-20
by Sean McGinnis 13 Sep '19

13 Sep '19

Development Focus ----------------- We just passed feature freeze! Until release branches are cut, you should stop accepting featureful changes to deliverables following the cycle-with-rc release model, or to libraries. Exceptions should be discussed on separate threads on the mailing-list, and approved by the team's PTL. Focus should be on finding and fixing release-critical bugs, so that release candidates and final versions of the Train deliverables can be proposed, well ahead of the final Train release date. General Information ------------------- We are still finishing up processing a few release requests, but the Train release requirements are now frozen. If new library releases are needed to fix release-critical bugs in Train, you must request a Feature Freeze Exception (FFE) from the requirements team before we can do a new release to avoid having something released in Train that is not actually usable. This is done by posting to the openstack-discuss mailing list with a subject line similar to: [$PROJECT][requirements] FFE requested for $PROJECT_LIB Include justification/reasoning for why a FFE is needed for this lib. If/when the requirements team OKs the post-freeze update, we can then process a new release. A soft String freeze is now in effect, in order to let the I18N team do the translation work in good conditions. In Horizon and the various dashboard plugins, you should stop accepting changes that modify user-visible strings. Exceptions should be discussed on the mailing-list. By September 26 this will become a hard string freeze, with no changes in user-visible strings allowed. Actions --------- stable/train branches should be created soon for all not-already-branched libraries. You should expect 2-3 changes to be proposed for each: a .gitreview update, a reno update (skipped for projects not using reno), and a tox.ini constraints URL update. Please review those in priority so that the branch can be functional ASAP. The Prelude section of reno release notes is rendered as the top level overview for the release. Any important overall messaging for Train changes should be added there to make sure the consumers of your release notes see them. Finally, if you haven't proposed Train cycle-highlights yet, you are already late to the party. Please see http://lists.openstack.org/pipermail/openstack-discuss/2019-September/00913… for details. Upcoming Deadlines & Dates -------------------------- RC1 deadline: September 26 (R-3 week) Final RC deadline: October 10 (R-1 week) Final Train release: October 16 Forum+PTG at Shanghai summit: November 4

[goal][python3] Train unit tests weekly update (goal-0)
by Corey Bryant 13 Sep '19

13 Sep '19

This is the goal-0 weekly update for the "Update Python 3 test runtimes for Train" goal [1]. Today is the final day for completion of Train community goals [2]. == How can you help? == If your project has failing tests please take a look and help fix. Python 3.7 unit tests will be self-testing in Zuul. Failing patches: https://review.openstack.org/#/q/topic:python3-train +status:open+(+label:Verified-1+OR+label:Verified-2+) If your project has patches with successful tests please help get them merged. Open patches needing reviews: https://review.openstack.org/#/q/topic:python3 -train+is:open Patch automation scripts needing review: https://review.opendev.org/#/c/666934 == Ongoing Work == We're down to 3 projects with failing tests, and 2 projects with successful tests. Barbican and PowerVM are actively working on getting patches landed. I've not been successful in making contact with the Freezer PTL. Thank you to all who have contributed their time and fixes to enable patches to land! == Completed Work == All patches have been submitted to all applicable projects for this goal. Merged patches: https://review.openstack.org/#/q/topic:python3-train +is:merged == What's the Goal? == To ensure (in the Train cycle) that all official OpenStack repositories with Python 3 unit tests are exclusively using the 'openstack-python3-train-jobs' Zuul template or one of its variants (e.g. 'openstack-python3-train-jobs-neutron') to run unit tests, and that tests are passing. This will ensure that all official projects are running py36 and py37 unit tests in Train. For complete details please see [1]. == Reference Material == [1] Goal description: https://governance.openstack.org/tc/goals/train/ python3-updates.html [2] Train release schedule: https://releases.openstack.org/train /schedule.html (see R-5 for "Train Community Goals Completed") Storyboard: https://storyboard.openstack.org/#!/story/2005924 Porting to Python 3.7: https://docs.python.org/3/whatsnew/3.7.html#porting-to-python-3-7 Python Update Process: https://opendev.org/openstack/governance/src/branch/master/resolutions/2018… Train runtimes: https://opendev.org/openstack/governance/src/branch/master/reference/runtim… train.rst Thanks, Corey

[tc][uc][meta-sig] How to help SIGs to have a better life? (Needs feedback for SIGs guideline)
by Rico Lin 13 Sep '19

13 Sep '19

Hi all, The question I would like to ask is, what else we can do here to help SIGs to have a better life? What can we do from here? And is there any feedback regarding on experience of participate a SIG or chairing one? For some work in progress (or completed) actions: I'm working on a guideline for SIGs ( https://etherpad.openstack.org/p/SIGs-guideline ) because I believe it might provide some value for SIGs, especially new-formed SIGs. Please kindly provide your feedback on it. Will send a patch to update current document under governance-sigs once we got good enough confident on it. On the other hand, the reason I start this work is because we're thinking `How to help SIGs to have a better life?` There're some actions I can think of and the most easier answers are to get SIGs status, update guidelines and explain why we need SIG in general. So actions: I'm working on SIG guideline ( https://etherpad.openstack.org/p/SIGs-guideline ) and document `Comparison of Official Group Structures` ( https://review.opendev.org/#/c/668093/ ). Also, reach out to SIGs earlier this year to collect help most needed information for SIGs and WGs ( https://etherpad.openstack.org/p/DEN-help-most-needed-for-sigs-and-wgs ) Also, I know Belmiro Moreira (UC member) has reached out to SIGs too, so there are some up to date information. I will try to put all the above information together for share. And now, back to the question, what can we do from here? Or is there any other feedback? Before I start to disturb everyone with crazy ideas in my mind, would like to hear feedback from all of you. Finally, feedback on SIG guideline is desired. Thanks! -- May The Force of OpenStack Be With You, *Rico Lin*irc: ricolin

Re: [nova] Deprecating the XenAPI driver
by James Benson 12 Sep '19

Matt, I am currently working on trying to deploy Xen OpenStack. Currently I have been trying to get it working on Rocky with Xen6.0 and will code fix for Stein/Train as well if possible. Trying to get a working solution with Rocky then will patch up the line. I have reached out to the last person who submitted a bug fix in Xen (with no response), but I am actively trying to get this working. Unfortunately it is a one-man job, so it is taking a lot of time. Currently facing issues with Nova and Neutron. James

Re: [Openstack-stable-maint] Stable check of openstack/swift for ref refs/heads/stable/pike failed
by Tim Burke 12 Sep '19

12 Sep '19

Wrote up https://bugs.launchpad.net/swift/+bug/1843816 to describe the issue; tl;dr is that python's http.client/httplib got more picky about sending only RFC-compliant HTTP requests, but Swift's proxy was happy to accept non-compliant query strings and try to forward them on to backend servers. Fix for master is up at https://review.opendev.org/#/c/681875/, and a backport for pike is up at https://review.opendev.org/#/c/681879/.

Hi, As discussed in the release meeting today, I'm requesting an FFE for oslo.policy, oslo.privsep, and oslo.service. The latter two are only release notes for things that landed late in the cycle, and oslo.policy is a small bugfix in sample policy generation. These should all be backportable if necessary, but for convenience we'd like to get them out now. Thanks. -Ben

[openstack-ansible] office hours update
by Mohammed Naser 12 Sep '19

12 Sep '19

Hi everyone, Here’s the update of what happened in this week’s OpenStack Ansible Office Hours. We finished installing the Python3 for ansible-runtime virtual environment. We discussed how Centos 7.7 wasn’t out yet but we want to move to Python 3 so we’ll start using the CR repository. The placement extract and upgrade jobs are in progress. We clarified the whole definition around freezing a milestone and features and what it implies. The roles for Train milestones were frozen. We’ll wait for Python3, placement and bind-to-mgmt before proposing the milestone. Galera is still having issues and we’re having trouble understanding and fixing them but it has something to do with listening to localhost. We tested Ansible 2.9 and are trying to figure out if we want to use it for Train. We’re having issues with bumping up os-vif for Stein because they seem to be only for testing according to OpenStack Requirements. We talked about maybe using the in-repository local constraints or creating a tag, but we don’t think they can be bumped. It seems later that it was clarified that we can do that, and os-vif made a new release today so we can check it out. Finally, we discussed a journal logging error on Stein. There’s a case of python-systemd missing for logging. Thanks!

How to boot 2 VMs in openstack on same subnet?
by Paul Belanger 11 Sep '19

11 Sep '19

Greetings, We use a few openstack public clouds for testing in the ansible project, specifically using nodepool. We have a use case, where we need to boot 2 VMs on the same public subnet for testing reasons. However, the majority of the clouds we are using, do not have a single subnet for their entire public IP range. Up until now, we boot the 2 VMs, then hope they land on the same subnet, but this isn't really efficient. Basically looking to see if there is a better way to handle this either via openstacksdk or some other configuration we need cloud side. Also note, we'd like to do this with public provider network (which we don't have control over) and avoid using private network for now. Paul

Re: [Horizon] Paging and Angular...

Unfortunately the people who originally > introduced Angular in Horizon and designed how it is used are no longer interested in contributing, > and there don't seem to be any new people able to handle this. I've been working with Horizon's Angular for quite some time and don't mind keeping at it, but it's useless unless I can get my code merged, hence my original message. As far as attracting new developers goes, I think that removing some barriers to entry couldn't hurt - seeing commits simply lost to time being one of them. I can see it as being fairly demoralizing. > Personally, I think that a better long-time strategy would be to remove all > Angular-based views from Horizon, and focus on maintaining one language and one set of tools. Removing AngularJS wouldn't remove JavaScript from horizon. We'd still be left with a home-brewish framework (which is buggy as is). I don't think removing js completely is realistic either: we'd lose functionality and worsen user experience. I think that keeping Angular is the better alternative: 1) A lot of work has already been put into Angularization, solving many problems 2) Unlike legacy js, Angular code is covered by automated tests 3) Arguably, improvments are, on average, easier to add to Angular than pure js implementations Whatever reservations there may be about the current implementation can be identified and addressed, but all in all, I think removing it at this point would be counterproductive.

RE: [winstackers][powervmstackers][tc] removing winstackers and PowerVMStackers from TC governance
by Lucian Petrut 11 Sep '19

11 Sep '19

Hi, I had a chat with my team and we think it would be best if we could keep Winstackers as a separate team. This is mostly because of the associated projects, which are essential for the Windows – Openstack integration effort. Other teams may not be interested in adopting those projects, which would be required if we chose the SIG route. Despite missing this election, I can assure you that we’re quite active in this endeavor. I’m willing to take the PTL role, offloading this task from Claudiu, whose time was quite limited recently.

[all] [tc] [ptls] PDF Goal Update
by Alexandra Settle 11 Sep '19

11 Sep '19

Hi all, According to the Train schedule, this week is the week of "Train Community Goals completed" [1]. In the last few weeks, we've been working hard on the goal to enable PDF support in the project docs. We have successfully completed... 1. Creating a workable solution [2] 2. Communicating this solution via ML [3] As far as the success of the goal is, that has to be measured by the individual teams. But it looks like we're all going really well at implementing the new changes [4]. Thanks to everyone who has jumped in from across the board to make this a success! I wanted to touch base with the teams and gather a status update from the PTLs or project liaisons on where they are at, what questions they may have, and how we (the docs team and TC) can help. Over the next week I will reach out to each team and gather a status update of sorts.

[nova][glance][entropy][database] update glance metadata for nova instance
by Jordan Ansell 11 Sep '19

11 Sep '19

Hi Openstack Discuss, I have an issue with nova not synchronizing changes between a glance image and it's local image meta information in nova. I have updated a glance image with the property "hw_rng_model=virtio", and that successfully passes that to new instances created using the updated image. However existing instances do not receive this new property. I have located the image metadata within the nova database, in the **instance_system_metadata** table, and can see it's not updated for the existing instances, and only adding the relevant rows for instances that are created when that property is present. The key being "image_hw_rng_model" and "virtio" being the value. Is there a way to tell nova to update the table for existing instances, and synchronizing the two databases? Or is this the kind of thing that would need to be done *shudder* manually...? If so, are there any experts out there who can point me to some documentation on doing this correctly before I go butcher a couple of dummy nova database? Regards, Jordan

[tc] monthly meeting summary
by Mohammed Naser 10 Sep '19

10 Sep '19

Hi everyone, The TC held it’s monthly meeting on the 5th of September 2019 and this email provides a summary of that meeting. We contacted Alan to mention that TC will have some presence at the Shanghai leadership meeting alongside other OSF projects on November 3rd, so the day before the summit. Rico is currently working on an etherpad to update SIG guidelines to simplify the process for new SIGs. Once the draft version is done, they will ask SIG chairs to join in the editing part. We still have to contact interested parties for a new ‘large scale’ SIG so we will follow up again on that action item in the next meeting. Graham is currently in the process of testing the code in order to make the proposal bot for propose project-template patches for specific releases. We’re working on adding some forum sessions ideas for the TC and we’ve got volunteers in the forum selection committee. Thierry finished making goal selection a two-step process and it's been merged. There are a few projects that lacked a PTL elected, we’ve discussed the following points for each: - Cyborg: Sundar self-nominated but only on the mailing list, therefore we will appoint them. - Designate: The developers who have expressed interest didn’t have commits, so Graham will sync with both of them to see how if can make it work. - OpenstackSDK: Monty might have missed the notice since they were traveling so Thierry will reach out to him to see if they want to take it again or has suggestions. - I18n: Ian Y. Choi expressed interest but couldn’t run because they were an election official. - {PowerVM,Win}stackers: The code and review activity was quiet and they missed election twice in a row so we proposed to remove them from project teams list and if they want to continue they can as a SIG. - Placement: we are trying to find someone to volunteer by reaching out to Placement and Nova team. We started discussing a change in the process for release names and the rest of that discussion carried over into office hours. I hope that I covered most of what we discussed, for the full meeting logs, you can find them here: http://eavesdrop.openstack.org/meetings/tc/2019/tc.2019-09-05-14.00.log.html Thanks!

[Horizon] Help making custom theme
by Amy Marrich 10 Sep '19

10 Sep '19

For the Grace Hopper Conference's Open Source Day we're doing a Horizon based workshop for OpenStack (running Devstack Pike). The end goal is to have the attendee teams create their own OpenStack theme supporting a humanitarian effort of their choice in a few hours. I've tried modifying the material theme thinking it would be the easiest route to go but that might not be the best way to go about this.:) I've been getting some assistance from e0ne in the Horizon channel and my logo now shows up on the login page, and I had already gotten the SITE_BRAND attributes and the theme itself to show up after changing the local_settings.py. If anyone has some tips or a tutorial somewhere it would be greatly appreciated and I will gladly put together a tutorial for the repo when done. Thanks! Amy (spotz)

[release][cyborg] os-acc status
by Thierry Carrez 10 Sep '19

10 Sep '19

Hi Cyborgs, One of your deliverables is the os-acc library. It has seen no change over this development cycle and therefore was not released at all in train. We have several options for this library now: 1- It's still very much alive and desired and just has exceptionally not seen much activity during this cycle. We should just cut a stable/train branch from the last release available (0.2.0) and continue in ussuri. 2- It's a valuable library, it just changes extremely rarely. We should make it independent from the release cycle and have it release at its own rhythm. 3- Development has stopped on this, and the library is not useful right now. We should retire this deliverable so that we do not build wrong expectations for our users. Please let us know which option fits the current status of os-acc. -- Thierry Carrez (ttx)

OSA upgrading Xenial Queens to Bionic Rocky
by Grant Morley 10 Sep '19

10 Sep '19

Hi all, I was wondering if there was a guide for upgrading OpenStack Ansible from Ubuntu 16.04 Queens to Ubuntu 18.04 Rocky? I remember a long time ago there was an etherpad set up for upgrading from 14.04 -> 16.04 but I can't seem to find anything similar for going to 18.04. Annoyingly as we don't have lots of hardware, we are going to have to upgrade in place. If there are any guides that would be much appreciated. Many thanks. -- Grant Morley Cloud Lead, Civo Ltd www.civo.com <https://www.civo.com/>| Signup for an account! <https://www.civo.com/signup>

All the documentation that I found explain how do it with distributed switches or port groups but currently in my setup, vmware is using Standard Network. Openstack Stein was deployed using OSA , neutron was configured using ovs and i configured the integrated_bridge to br-int. I tried first to deployed using linux-bridge but when I tried to deployed an instance, neutron returned that only ovs or dvs method is supported. Now when ovs when I'm deploying an instance with network, nova returns an error message: 2019-09-10 10:15:19.010 22443 ERROR nova.compute.manager [instance: d8d1cbb8-5c1c-4b98-9739-bea0668cfaa5] VimFaultException: An error occurred during host configuration. 2019-09-10 10:15:19.010 22443 ERROR nova.compute.manager [instance: d8d1cbb8-5c1c-4b98-9739-bea0668cfaa5] Faults: ['PlatformConfigFault'] How do you guys integrate neutron with vmware vsphere with standard network?

Thank you Stackers for five amazing years!
by Chris Hoge 10 Sep '19

10 Sep '19

Hi everyone, After more than nine years working in cloud computing and on OpenStack, I've decided that it is time for a change and will be moving on from the OpenStack Foundation. For the last five years I've had the honor of helping to support this vibrant community, and I'm going to deeply miss being a part of it. OpenStack has been a central part of my life for so long that it's hard to imagine a work life without it. I'm proud to have helped in some small way to create a lasting project and community that has, and will continue to, transform how infrastructure is managed. September 12 will officially be my last day with the OpenStack Foundation. As I make the move away from my responsibilities, I'll be working with community members to help ensure continuity of my efforts. Thank you to everyone for building such an incredible community filled with talented, smart, funny, and kind people. You've built something special here, and we're all better for it. I'll still be involved with open source. If you ever want to get in touch, be it with questions about work I've been involved with or to talk about some exciting new tech or to just catch up over a tasty meal, I'm just a message away in all the usual places. Sincerely, Chris chris(a)hogepodge.com Twitter/IRC/everywhere else: @hogepodge

[keystone] cannot use 'openstack trust list' without admin role
by Francois Scheurer 10 Sep '19

10 Sep '19

Dear Keystone Experts, I have an issue with the openstack client in stage (using Rocky), using a user 'fsc' without 'admin' role and with password auth. 'openstack trust create/show' works. 'openstack trust list' is denied. But keystone policy.json says: "identity:create_trust": "user_id:%(trust.trustor_user_id)s", "identity:list_trusts": "", "identity:list_roles_for_trust": "", "identity:get_role_for_trust": "", "identity:delete_trust": "", "identity:get_trust": "", So "openstack list trusts" is always allowed. In keystone log (I replaced the uid's by names in the ouput below) I see that 'identity:list_trusts()' was actually granted but just after that a_*admin_required()*_ is getting checked and fails... I wonder why... There is also a flag*is_admin_project=True* in the rbac creds for some reason... Any clue? Many thanks in advance!

[ironic] Ironic tempest jobs hitting retry_limit failures
by Clark Boylan 09 Sep '19

09 Sep '19

Hello Ironic, We've noticed that your tempest jobs have been hitting retry_limit failure recently. What this means is we attempted to run the job 3 times but each time the job failed due to "network" problems and Zuul eventually gave up. On further investigation I found that this is happening because the ironic tempest jobs are filling the root disk on rackspace nodes (which have a smaller root / + ephemeral drive mounted at /opt) with libvirt qcow2 images. This seems to cause ansible to fail to operate because it needs to write to /tmp and it thinks there is a "network" error. I've thrown my investigation into a bug for you [0]. It would be great if you could take a look at this as we are effectively spinning our wheels for about 9 hours every time this happens. I did hold the node I used to investigate. If you'd like to dig in yourselves just ask the infra team for access to nodepool node ubuntu-bionic-rax-ord-0011007873. Finally, to help debug these issues in the future I've started adding a cleanup-run playbook [1] which should give us network and disk info (can be expanded if necessary too) for every job when it is done running. Even if the disk is full. [0] https://storyboard.openstack.org/#!/story/2006520 [1] https://review.opendev.org/#/c/681100/ Clark

[devstack][qa][python3] "also install the Python 2 dev library" - still needed?
by Peter Penchev 09 Sep '19

09 Sep '19

Hi, When devstack's `setup_dev_lib` function is invoked and USE_PYTHON3 has been specified, this function tries to also install the development library for Python 2.x, I guess just in case some package has not declared proper Python 3 support or something. It then proceeds to install the Python 3 version of the library and all its dependencies. Unfortunately there is a problem with that, and specifically with script files installed in the system's executable files directory, e.g. /usr/local/bin. The problem appears when some Python library has already been installed for Python 3 (and has installed its script files), but is now installed for Python 2 (overwriting the script files) and is then not forcefully reinstalled for Python 3, since it is already present. Thus, the script files are last modified by the Python 2 library installation and they have a hashbang line saying `python2.x` - so if something then tries to execute them, they will run and use modules and libraries for Python 2 only. We experienced this problem when running the cinderlib tests from Cinder's `playbooks/cinderlib-run.yaml` file - it finds a unit2 executable (installed by the unittest2 library) and runs it, hoping that unit2 will be able to discover and collect the cinderlib tests and load the cinderlib modules. However, since unittest2 has last been installed as a Python 2 library, unit2 runs with Python 2 and fails to locate the cinderlib modules. (Yes, we know that there are other ways to run the cinderlib tests; this message is about the problem exposed by this way of running them) The obvious solution would be to instruct the Python 2 pip to not install script (or other shared) files at all; unfortunately, https://github.com/pypa/pip/issues/3980 ("Option to exclude scripts on install"), detailing a very similar use case ("need it installed for Python 2, but want to use it with Python 3") has been open for almost exactly three years now with no progress. I wonder if I could try to help, but even if this issue is resolved, there will be some time before OpenStack can actually depend on a recent enough version of pip. A horrible workaround would be to find the binary directory before installing the Python 2 library (using something like `pip3.7 show somepackage` and then running some heuristics on the "Location" field), tar'ing it up and then restoring it... but I don't know if I even want to think about this. Another possible way forward would be to consider whether we still want the Python 2 libraries installed - is OpenStack's Python 3 transition reached a far enough stage to assume that any projects that still require Python 2 *and* fail to declare their Python 2 dependencies properly are buggy? To be honest, this seems the most reasonable path for me - drop the "also install the Python 2 libs" code and see what happens. I could try to make this change in a couple of test runs in our third-party Cinder CI system and see if something breaks. Here is a breakdown of what happens, with links to the log of the StorPool third-party CI system for Cinder: https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `stack.sh` invokes `pip_install` for `os-testr` https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `pip_install` sees that we want a Python 3 installation and invokes `pip3.7` to install os-testr. https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `pip3.7` wants to install `unittest2` https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `pip3.7` has installed `unittest2` - now `/usr/local/bin/unit2` has a hashbang line saying `python3.7` Now this is where it gets, uhm, interesting: https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `setup_dev_lib` is invoked for `os-brick` https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `setup_dev_lib`, seeing that we really want a Python 3 installation, decides to install `os-brick` for Python 2 just in case. https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `pip2.7` is invoked to install `os-brick` and its dependencies. https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `pip2.7` decides it wants to install `unittest2`, too. https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `pip2.7` has installed `unittest2`, and now `/usr/local/bin/unit2` has a hasbang line saying `python2.7` https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `setup_dev_lib` turns the Python 3 flag back on. https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `pip3.7` is invoked to install `os-brick` https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `pip3.7` decides (correctly) that it has already installed `unittest2`, so (only partially correctly) it does not need to install it again. Thus `/usr/local/bin/unit2` is left with a hashbang line saying `python2.7`. Thanks for reading this far, I guess :) G'luck, Peter

[nova] Offline Installation of Openstack
by Premdeep S 09 Sep '19

09 Sep '19

Hi Team, Requesting your help on below. We have a requirement to setup Openstack in an isolated infra. We will not be provided with Internet. How can we set it up? 1. Can we have a local repository (Rocky, Universal, etc)created? If so how do we manage it? 2. We have noticed lot of package dependencies while setting up Openstack Infra, so will creating a local repository help in an implementation when we do not have an internet. What is the success rate? Thanks Prem

[manila][ops] Shanghai Forum - Manila Topic Planning
by Tom Barron 09 Sep '19

09 Sep '19

As mentioned several times in the Manila Community Meeting, we have posted an etherpad to brainstorm and gauge interest in topics for the Forum at the upcoming OpenInfra Summit in Shanghai. The point of the Forum sesssions is to get feedback from operators and users on things that need fixing, improvements and enhancements, and more generally about the strategic direction for Manila. So please take a look and update this etherpad with topic ideas and indicate your interest in topics already present if you have an interest in Manila. It doesn't matter whether you contribute to the project or not, or whether you will yourself be attending the Forum: https://etherpad.openstack.org/p/manila-shanghai-forum-brainstorming We will review this etherpad in our community meeting at 1500 UTC on 19 September in #openstack-meeting-alt on Freenode, one day before the Forum proposal deadline. Please feel free to join that meeting to discuss, and in any case please add to the brainstorming deadline before then. Cheers, -- Tom Barron

[keystone] Pre-feature-freeze update
by Colleen Murphy 09 Sep '19

09 Sep '19

I won't be writing a team report since I'm still figuring out which way is up after a week in the desert, but with feature freeze next week I wanted to give a status update on all the in-flight work that is due next week: * System Scope and Default Roles All documented scope[1] and role[2] migrations are in progress. Some are closer to done than others. Since enforce_scope cannot be set to true in keystone.conf until all of them are completed, and since leaving deprecation warnings in the logs for more than two cycles is a very undesirable operator experience, it's essential we complete these by next week. * Application Credential Access Rules This implementation[3] for keystone has been completed for months but the last few patches in the stack are lacking reviews. Client support has been proposed but with the final client release happening next week we will likely not land it until next cycle. * Resource Options and Immutable Resources Resource options[4] and immutable resources[5] are intertwined and the finishing touches are still being applied. Hope to have this completed early next week. * Federated Attributes for Users Support for federated attributes for users[6] is passing CI but needs reviews, it's unclear to me how much has changed since those patches were originally proposed two years ago so it's unfortunate that we're only left with a week to look at them. * Expiring Group Membership There is only a partial implementation proposed for expiring group membership[7] and neither patch is passing CI. This seems to have effectively missed the feature proposal freeze deadline which was a few weeks ago and will not likely make it in this cycle. * CI After skimming the meeting logs I saw the unit test timeout problem was discussed and a temporary workaround was proposed[8]. This sounded like a great idea but it seems that no one implemented it, so I did[9]. Unfortunately this will conflict with all the system-scope/default-roles patches in flight. With how many changes need to go in and how slow it will be with all of them needing to be rechecked and continually making the problem even worse, I propose we go ahead and merge the workaround ASAP and update all the in-flight changes to move the protection tests to the new location. It also appears that the non-voting federation CI broke recently, this will hopefully be fixed by updating the opensuse nodeset[10].

[nova][telemetry] does Telemetry still use the Nova server usage audit log API?
by melanie witt 09 Sep '19

09 Sep '19

Howdy all, TL;DR: I have a question, does the Telemetry service (or any other service) still make use of the server usage audit log API in Nova [1]? Recently I was investigating customer issues where the nova.task_log database table grows infinitely and is never cleaned up [2]. I asked about it today in #openstack-nova [3] and Matt Riedemann explained that the API is toggled via config option [4] and that the Telemetry service is/was the consumer of the API. I found through code inspection that there are no methods for deleting nova.task_log records and am trying to determine what is the best way forward for handling cleanup. Matt mentioned the possibility of deprecating the server usage audit log API altogether, which we might be able to do if no one is using it anymore. So, I was thinking: * If Telemetry is no longer using the server usage audit log API, we deprecate it in Nova and notify deployment tools to stop setting [DEFAULT]/instance_usage_audit = true to prevent further creation of nova.task_log records and recommend manual cleanup by users or * If Telemetry is still using the server usage audit log API, we create a new 'nova-manage db purge_task_log --before <date>' (or similar) command that will hard delete nova.task_log records before a specified date or all if --before is not specified Can anyone shed any light on whether Telemetry, or any other service, still uses the server usage audit log API in Nova? Would we be able to deprecate it? If we can't, what do you think of the nova-manage command idea? I would appreciate hearing your thoughts about it.

[nova][neutron][all][openstack-devs] studying and analysing Openstack developers
by Farida El Zanaty 09 Sep '19

09 Sep '19

Hi! I am Farida El-Zanaty from McGill University. Under the supervision of Prof. Shane McIntosh, my research aims to study design discussions that occur between developers during code reviews. Last year, we published a study about the frequency and types of such discussions that occur in OpenStack Nova and Neutron (http://rebels.ece.mcgill.ca/papers/esem2018_elzanaty.pdf). We are reaching out to OpenStack developers to better understand their perspectives on design discussions during code reviews. Those who are interested can start by participating in our 10-minute survey about their experiences as both the code reviewer and author. Survey participants will be entered into a raffle for a $50 Amazon gift card. Survey: https://forms.gle/Hhn191f6cxF5hVgG8 Thanks for your time, Farida El-Zanaty

And I would agree that from that standpoint it is open source, and the four opens are good both in letter and in spirit. I would also agree that the academic and other non-profit use of a OpenStack that Jeremy is very compelling and motivating. But the context of much of this thread has been about the experience of the developers making OpenStack. How they come to be in this situation, how they manage their work, who they work with, what drives decisions, etc. (What follows is a ramble. A apologize for not being able to write less. But you did ask so here it goes.) In the context of daily developer experience, things are less clear. They would be more clear and would feel more like open source if I was more frequently collaborating in the creation of code with people who were using OpenStack. But I don't. Most frequently I'm collaborating with people who instead of using OpenStack are helping to make something for other people (with whom they have infrequent collaborative contact) to use OpenStack. For some people this is not the case. For example, many of the people who have been deeply involved with OpenStack infra use OpenStack all the time and also work hard to improve the code of OpenStack. But on a daily basis that isn't my experience. Nor does it feel like the experience of most of the people I tend to collaborate with. Yes, sometimes I will collaborate with someone from CERN to create a feature, but this is rare. Usually I collaborate with people from Intel, VMware, Red Hat, and a variety of Telco vendors. Doing a thing to help an existing customer or hoped for notional customer, both of whom are abstractions at a distance, not humans. This isn't a bad thing. Organizations collaborating in any way is great. But it doesn't _feel_ like "open source" to me. And that feeling is an important factor (I think) in analyzing the motivations people experience when working on OpenStack and the choices they make with regard to how they act in the environment. As someone who has done what could be called open source since long before the term was invented, the common failure of corporate patrons to give maintainability and quality (of product and (critically) the experience of creating it) sufficient attention is a source of a great deal of resentment and internal conflict. I am far too conscious of the necessity to compensate for that failure if I want to feel a sense of well being with what I'm helping to create (both in terms of product and the environment it is being created in). That is: I care enough to try to do what I think is right. In this thread, and the one that started it, we've put forward the "maybe we should just chill" as a bit of an antidote to burnout and overcommitment. While I rationally think that's the right idea, emotionally it is very hard to do and the source of that difficulty is this: OpenStack has constituted itself over the years as the domain of contributing corporations. Many paid contributors for whom working on OpenStack is their job. At the same time we have also been very vocal about being not just open source, but a source of good wisdom (the four opens) on how to do open source well. The latter creates a community I want to believe in. A source of pride. The former creates a conflict of interest, a frequent inability to do the actually right thing for the long term health of the community. A source of shame. Continued pleas to get the corporates to do "open source" well -- that is with correct attention to: * developer experience * maintainability * architectural integrity * deeper/closer ties to user engagement and their satisfaction and thus some akin to "actually open source" -- have fallen on what, if actions speak louder than words, are deaf ears. This creates a conundrum. I've tried a variety of ways out of it. One I'm experimenting with now is realizing that OpenStack really isn't, now, proper open source. And if it is not, then I don't have to care because they don't. > Again I'd be very interested to learn more about your take on what we > can do better. There are two directions to go: Maintain the mode of corporate-contribution-driven development. If this is to be healthy then the corps doing that contribution need to invest far more heavily in general, but especially in the items I've listed above at "correct attention". This would grant the community sufficient resources to evolve out of its aging models for development and governance. You have to have some free space to have the head space to get to new spaces. Start breaking down the corporate-contribution-driven development. Encourage professional openstack devs (like me) to age out of the system and discourage new ones coming in. Encourage feature development from and via users. Feature velocity might drop drastically but they might be features individuals actually use within a few weeks of their release rather than a few years. Some of this latter is already happening. Especially in what some people call the non-core projects; things associated with deployment for example. But in projects like nova we're heavily driven by trying to create a feature base which is predicted to drive sales, either directly or indirectly. And, though opinions and experiences differ, my opinion and experience is that driving sales as a direct factor is anathema to "open source". Indirect? Sure, whatever, if that floats your boat. The proper direct factor is humans. There's a lot more to this than I've stated here, but I hope that gives at least something in answer to the question. -- Chris Dent ٩◔̯◔۶ https://anticdent.org/ freenode: cdent

[all][ptl][tc][docs] Develope a code-review practices document
by Trinh Nguyen 09 Sep '19

09 Sep '19

Hi all, I find it's hard sometimes to handle situations in code-review, something likes solving conflicts while not upsetting developers, or suggesting a change to a patchset while still encouraging the committer, etc. I know there are already documents that guide us on how to do a code-review [2] and even projects develope their own procedures but I find they're more about technical issues rather than human communication. Currently reading Google's code-review practices [1] give me some inspiration to develop more human-centric code-review guidelines for OpenStack projects. IMO, it could be a great way to help project teams develop stronger relationship as well as encouraging newcomers. When the document is finalized, I then encourage PTLs to refer to that document in the project's docs. Let me know what you think and I will put a patchset after one or two weeks. [1] https://google.github.io/eng-practices/review/ [2] https://docs.openstack.org/project-team-guide/review-the-openstack-way.html [3] https://docs.openstack.org/doc-contrib-guide/docs-review.html [4] https://docs.openstack.org/nova/rocky/contributor/code-review.html [5] https://docs.openstack.org/neutron/pike/contributor/policies/code-reviews.h… Bests, -- *Trinh Nguyen* *www.edlab.xyz <https://www.edlab.xyz>*

[winstackers][powervmstackers][tc] removing winstackers and PowerVMStackers from TC governance

Following the U cycle election there was no candidate for either the winstackers or powervmstackers team PTL role. This is the second cycle in a row where that problem has occurred for both teams, which indicates that the teams are not active in the community. During the TC meeting today [1] we discussed removing the teams from governance, so I have proposed the patches to do that [2][3].

[placement] "now" worklist
by Chris Dent 09 Sep '19

09 Sep '19

As we near the end of a cycle it can be a bit unclear what tasks are relevant or a priority for the placement project. I've made a worklist in storyboard https://storyboard.openstack.org/#!/worklist/754 called "placement now". It gathers stories from the placement group (placement, osc-placement, os-resource-classes, os-traits) that I've tagged with 'pnow' to mean "these are the things we should be concerned with in the near future". This helps to take off the radar anything from the following groups: * Features that will not be considered this cycle. * Anything related to osc-placement (which has already seen its likely last release for this cycle) This leaves placement (the service) bug fixes, and docs. Not yet there is an item for "documenting the new nested provider features", mostly because the story for that has not solidified. Anything that is currently on that list we should finish before the end of the cycle. I hope that having a focused list can help drive that. Thanks. -- Chris Dent ٩◔̯◔۶ https://anticdent.org/ freenode: cdent

[mistral] Publish field in workflow tasks
by Ali Abdelal 09 Sep '19

09 Sep '19

Hello, Currently, there are two "publish" fields, one in the task(regular "publish")-the scope is branch and not global, and another under "on-success", “on-error” or “on-complete”. In the current behavior, regular "publish" is ignored if there is "publish" under "on-success", “on-error” or “on-complete” [1]. For example:- (a) version: '2.0' wf1: tasks: t1: publish: res_x1: 1 on-success: publish: branch: res_x2: 2 (b) version: '2.0' wf2: tasks: t1: publish: res_x1: 1 "res_x1" won't be published in (a), but it will in (b). We can either:- 1) Invalidate such syntax. 2) Merge the two publishes together and if there are duplicate keys, there are two options:- a) What takes priority is what's in publish under "on-success" or “on-error” or “on-complete. b) Not allow having a duplicate. What is your opinion? And please tell us if you have other suggestions. [1] https://bugs.launchpad.net/mistral/+bug/1791449

[heat] Resource handling in Heat stacks
by Andreas Florath 08 Sep '19

08 Sep '19

Hello! Can please anybody tell me, if all resources which are created within a Heat stack belong to the stack in the way that all the resources are freed / deleted when the stack is deleted? IMHO all resources which are created during the initial creation or update of a stack, even if they are ephemeral or only internal created, must be deleted when the stack is deleted by OpenStack Heat itself. Correct? My question might see obvious, but I did not find an explicit hint in the documentation stating this. The reason for my question: I have a Heat template which uses two images to create a server (using block_device_mapping_v2). Every time I run an 'openstack stack create' and 'openstack stack delete' cycle one ephemeral volume is left over / gets not deleted. For me this sounds like a problem in OpenStack (Heat). (It looks that this is at least similar to https://review.opendev.org/#/c/341008/ which never made it into master.) Kind regards Andre

[tc][neutron] Supported Linux distributions and their kernel
by Adrian Chiris 08 Sep '19

08 Sep '19

Greetings, I was wondering what is the guideline in regards to which kernels are supported by OpenStack in the various Linux distributions. Looking at [1], Taking for example latest CentOS major (7): Every "minor" version is released with a different kernel version, the oldest being released in 2014 (CentOS 7.0, kernel 3.10.0-123) and the newest released in 2018 (CentOS 7.6, kernel 3.10.0-957) While I understand that OpenStack projects are expected to support all CentOS 7.x releases. Does the same applies for the kernels they originally came out with? The reason I'm asking, is because I was working on doing some cleanup in neutron [2] for a workaround introduced because of an old kernel bug, It is unclear to me if it is safe to introduce this change. [1] https://governance.openstack.org/tc/reference/project-testing-interface.htm… [2] https://review.opendev.org/#/c/677095/ Thanks, Adrian.

[Octavia]-Seeking some high points on using Octavia
by Singh, Prabhjit 07 Sep '19

07 Sep '19

Hi Michael, I have been trying to get Octavia LbaaS up and running and get performance tested. It has taken me some time to get quite a few things working. While I continue to invest time in using Octavia and stay excited on some of the upcoming features. I have been asked the following questions by my leadership to which I do not have any direct answers. 1. What is the adoption of Octavia, are major organizations looking to adopt and invest in it. Can you provide some numbers 2. Roadmap wise is the Open community committed to investing in Octavia and why 3. Per your suggestion I tried to look up who are the primary companies using Octavia and haven't found a clear indication, any insight would be great. 4. Would features from haproxy 2.0 be included in Octavia 5. There are some open solutions from haproxy, Envoy, consul. How would Octavia compare. 6. Lastly, do you have enough encouragement to keep the project going, I guess I am looking for some motivation for continuing to choose to use Octavia when there are several turnkey solutions ( though offered at a price ). Currently I have been working with Redhat to answer the following questions, these are not for the community, hopefully Redhat will be able to pursue with your team. 1. How to offload logs to an external log/metrics collector 2. How to turn off logs during performance testing, I honestly do not want to do this because the performance tester is really generating live traffic which mimics a real time scenario. 3. How to set cron for rotating logs, I would think that this should be automatic. Would I need to do this everytime? 4. Do you have any way to increase performance of the amphora, my take is haproxy can handle several thousands of concurrent connections but in our case seems like we hit a threshold at 3500 - 4500 connections and then it starts to either send resets or the connections stay open for a long time.

I do understand you mentioned that it's hard to performance test Octavia but some real time situations from your testing and how customers have adopted Octavia would help me level set some expectations. This is really cloud and application specific. I would recommend you fire up an Octavia install and use your preferred tool to measure it. Some good tools are tsung, weighttp, and iperf3. > 2. We are thinking of Octavia as one of the offerings, that offers a self-serve type model. Do you know of any customers who have been able to use Octavia as one of their primary load balancers and any encouraging feedback you have gotten on Octavia. There are examples of organizations using Octavia available if you google Octavia. > 3. You suggested increasing the Ram size, I could go about making a whole new Flavor. Yes, to increase the allocated RAM for a load balancer, you would create an additional nova flavor with the specifications you would like. You can then either set this as the default nova flavor for amphora (amp_flavor_id is the setting) or you can create an Octavia flavor that specifies the nova compute flavor to use (See https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdocs.open… for more information on Octavia flavors). > 4. I also noticed on the haproxy.conf the maxconns is set to 2000, should I increase this, does this affect the connection per server, which you said 64000 conns per server, so if I have 10 servers can I expect somewhere close to 640000 sessions? I think you are looking at the haproxy.conf file provided by your operating system package. Octavia does not use this file, it creates it's own HAProxy configuration files as needed under /var/lib/octavia inside the amphora. The default, if the user does not specify one at listener creation, is 1,000,000. > 5. Based on some of the limitations and the dev work in progress, I think the most important feature that would make Octavia a real solid offering would be the Active-Active and Autoscaling feature. I brought this up with you in our brief conversation at the summit, and you did mention that its not a top priority at this time and you are looking for some help. I have noticed a lot of documentation has been updated on this feature, do you think with the available document and progress I could spin up a distributor and manage sessions between Amphora or it's not complete yet. Active/Active is still on our roadmap, but unfortunately the people that were working on it had to stop for personal reasons. There may be some folks picking up this work again soon. At this point the Active/Active patches up for review are non-functional and still a work in progress. > 6. We have a Triple O setup, do you think I can make the above tweaks with the Triple O setup. I think you are able to make various adjustments to Octavia with Triple O, but I do not have specifics on that. > Thanks & Regards > > Prabhjit Singh > Systems Design and Strategy - Magentabox > | O: (973) 397-4819 | M: (973) 563-4445 > > > > -----Original Message----- > From: Michael Johnson <johnsomor(a)gmail.com> > Sent: Friday, July 19, 2019 6:00 PM > To: Singh, Prabhjit <Prabhjit.Singh22(a)T-Mobile.com> > Cc: openstack-discuss(a)lists.openstack.org > Subject: Re: [Octavia]-Seeking performance numbers on Octavia > > [External] > > > Hi Prabhjit, > > As you have mentioned, it is very challenging to get accurate performance results in cloud environments.

This means that the testing environment does not reflect how the software is used in real world deployments. > An example of this is simply booting a VM can take up to ten minutes on Qemu with TCG when it takes about twenty seconds on a real OpenStack deployment. > With this resource limitation, we cannot effectively run performance benchmarking test jobs on the OpenDev environment. > > Because of this, we don't publish performance numbers as they will not reflect what you can achieve in your environment. > > Let me try to speak to your bullet points: > 1. The Octavia team has never (to my knowledge) claimed the Amphora driver is "carrier grade". We do consider the Amphora driver to be "operator grade", which speaks to a cloud operator's perspective versus the previous offering that did not support high availability, have appropriate maintenance tooling, upgrade paths, performance, etc. > To me, "carrier grade" has an additional level of requirements including performance, latency, scale, and availability SLAs. This is not what the Octavia Amphora driver is currently ready for. That said, third party provider drivers for Octavia may be able to provide a "carrier grade" level of load balancing for OpenStack. > 2. As for performance tuning, much of this is either automatically handled by Octavia or are dependent on the application you are load balancing and your cloud deployment. For example we have many configuration settings to tune how many retries we attempt when interacting with other services. In performing and stable clouds, these can be tuned down, in others the defaults may be appropriate. If you would like faster failover, at the expense of slightly more network traffic, you can tune the health monitoring and keepalived_vrrp settings. We do not currently have a performance tuning guide for Octavia but would support someone authoring one. > 3. We do not currently have a guide for this. I will say with the version of HAproxy currently being shipped with the distributions, going beyond the 1vCPU per amphora does not gain you much. With the release of HAProxy 2.0 this has changed and we expect to be adding support for vertically scaling the Amphora in future releases. Disk space is only necessary if you are storing the flow logs locally, which I would not recommend for a performance load balancer (See the notes in the log offloading guide: > https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdocs.open…). > Finally, the RAM usage is a factor of the number of concurrent connections and if you are enabling TLS on the load balancer. For typical load balancing loads, the default is typically fine. However, if you have high connection counts and/or TLS offloading, you may want to experiment with increasing the available RAM. > 4. The source IP issue is a known issue > (https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fstoryboar…). We have not prioritized addressing this as we have not had anyone come forward that they needed this in their deployment. If this is an issue impacting your use case, please comment on the story to that effect and provide a use case. This will help the team prioritize this work. > Also, patches are welcome! If you are interested in working on this issue, I can help you with information about how this could be added. > It should also be noted that it is a limitation of 64,000 connections per-backend server, not per load balancer. > 5. The team uses the #openstack-lbaas IRC channel on freenode and is happy to answer questions, etc. > > To date, we have had limited resources (people and equipment) available to do performance evaluation and tuning. There are definitely kernel and HAProxy tuning settings we have evaluated and added to the Amphora driver, but I know there is more work that can be done.

[tc] Campaign Question: Treating the Problem, not just the symptoms- Burnout, No Polling, etc
by Kendall Nelson 07 Sep '19

07 Sep '19

Hello :) Wanted to split the question Chris Dent asked here[1] into its own thread so people down the road and those tracking it now can find more easily. To kind of rephrase for everyone (Chris, correct me if I am wrong or not getting all of it): What do you think we, as a community, can do about the lack of candidates for roles like TC or PTL? How can we adjust, as a community, to make our governance structures fit better? In what wasy can we address and prevent burnout? I think JP[2] and Jay[3] already started to enumerate good ideas on the other thread, so to summarize/ expand/ add to their lists: - Reducing the number of TC members to 9, and maybe someday down to 7. When we were having polls for every election (maybe not every project) it was at a time where the electorate (and theoretically the number of possible candidates) was also huge. Since we have move past the hype curve and stabilized as a project, the number of polls we've (I say we because I used to be and still plan to help with elections) had to make have decreased. It seems to be a matter of proportions. - Continuing to improve education and onboarding process. Agreed 100%, but this should be an ongoing focus for everyone too- every contributor TC, PTL, or otherwise. The best way to get more people involved faster is a lower barrier to entry, but we all know that. Yes some things like gerrit and IRC are hard for people to get past and likely won't be changing for our community any time soon, but there are things like that with every community (I don't know if you have ever tried to push patches to k8s but their tagging of PRs is something they are working on making less complicated and better documented). Breaking down the onboarding process we have at the moment into smaller modules and clearly documenting the progression through those modules for new comers to easily find and work through is important. Also, though, having that be the only place that we, as a community, point to (meaning no duplicate information in multiple places like we have today) when new contributors have issues. - Better documentation of tribal knowledge. I proposed as a community goal for the U release[4], to formalize project specific onboarding information (some teams have already done this) and project specific guides for PTLs (I know we already have the broad strokes for all PTLs documented fairly well, but there's always project specific stuff) so that when there is a turn over mid release, its easier for someone new to step up. - Utilize the user survey to gather info about how/why contribution is happening or why they aren't contributing if that's the case. There are already several questions there from the TC about this topic in the survey, but perhaps they can be re-framed if we aren't getting the info we want from them. As a reminder, here they are: -- To which projects does your organization contribute maintenance resources, such as patches for bug fixes and code reviews on master or stable branches? -- What prevents you or your organization from contributing more maintenance resources, or makes contributing difficult? -- How do members of your organization contribute to OpenStack? I think the real issue is getting larger vendors of OpenStack to get their users to take the user survey. We have a pretty solid reach as it is, but there are a lot of people using OpenStack that don't take the survey that we don't know about even because they are confidential (their results can still be confidential if they take the survey). - Longer release cycle. I know this has come up a dozen or more times (and I'm a little sorry for bringing it up again), but I think OpenStack has stabilized enough that 6 months is a little short and now may finally be the time to lengthen things a bit. 9 months might be a better fit. With longer release cycles comes more time to get work done as well which I've heard has been a complaint of more part time contributors when this discussion has come up in the past. - Co-PTL type position? I've noticed and talked to several PTLs on a variety of projects that need a little extra help with the role. They either don't feel like they have all the experience they need to be PTL yet and so they want the previous PTL to help out still or maybe they want to do it, but there are enough variables in their day to day work (or lack of overlap tz wise with most of the other contributors to that project), that having a backup person to help out and backfill when they need help. - Talking to each other. I really honestly think just talking to one another could help too. When you find yourself in a conversation with someone about how unmotivated they are because they have a ton of work to do. You might offer to take something off their plate. Or help them see maybe they need to not take on anything new till some other work gets wrapped up. We are a community that succeeds together, so if you see someone burning themselves out do what you can to help lighten their load (helping directly is great, but there are plenty of other people in our community that you could call on to help too). Hopefully goes without saying, but don't burn yourself out trying to help someone else either. Some of these things are more actionable, others are still high level and need to have concrete actions tied to them, but I think there are plenty of things we can do to make progress here. -Kendall (diablo_rojo) [1] http://lists.openstack.org/pipermail/openstack-discuss/2019-September/00908… [2] http://lists.openstack.org/pipermail/openstack-discuss/2019-September/00908… [3] http://lists.openstack.org/pipermail/openstack-discuss/2019-September/00910… [4] https://etherpad.openstack.org/p/PVG-u-series-goals

[all][research] Survey for Openstack developers =)
by Farida El Zanaty 06 Sep '19

06 Sep '19

Hi!I am Farida from McGill University. I am trying to learn more about code reviews in the Openstack community, as I have been studying Openstack projects for a while. Please help me understand your perspective on design discussions during code reviews by filling up this 10-minute survey: https://forms.gle/Hhn191f6cxF5hVgG8 Survey participants will also be entered into a raffle for a $50 Amazon gift card. A little bit of context: Under the supervision of Prof. Shane McIntosh, my research aims to study design discussions that occur between developers during code reviews. Last year, we published a study about the frequency and types of such discussions that occur in OpenStack Nova and Neutron (http://rebels.ece.mcgill.ca/papers/esem2018_elzanaty.pdf<https://slack-redir.net/link?url=http%3A%2F%2Frebels.ece.mcgill.ca%2Fpapers…>).We are reaching out to Openstack developers to better understand their perspectives on design discussions during code reviews.

[all][tc] PDF Community Goal Update
by Akihiro Motoki 06 Sep '19

06 Sep '19

Hi all, I would like to share the status of the PDF community goal. We made great progresses these two weeks. Highlights ---------- It is time for working on the PDF community goal in your project! - openstack-tox-docs job supports PDF build now. AJaeger and I worked on the job support of PDF doc build and publishing and have completed it. - We confirmed PDF build with the sphinx latex builder works for several major projects like nova, cinder and neutron. The approach with the latex builder should work for most projects. - First PDF doc is now published from the i18n project. How to get started ------------------ - "How to get started" section in the PDF goal etherpad [1] explains the minimum steps. You can find useful examples there too. - To build PDF docs locally, you need to install LaTex related packages. See "To test locally" in the etherpad [1]. - If you hit problems during PDF build, check the common problems etherpad [2]. We are collecting knowledges there. - If you have questions, feel free to ask #openstack-doc IRC channel. Also Please sign up your name to "Project volunteers" in [1]. Useful links ------------ [1] https://etherpad.openstack.org/p/train-pdf-support-goal [2] https://etherpad.openstack.org/p/pdf-goal-train-common-problems [3] Ongoing reviews: https://review.opendev.org/#/q/topic:build-pdf-docs+(status:open+OR+status:… Thanks, Akihiro Motoki (amotoki)

[release][heat][nova][openstackclient][openstacksdk][nova] Pending final library releases
by Sean McGinnis 06 Sep '19

06 Sep '19

Hey everyone, Yesterday was the deadline for any non-client library releases. In order to make sure we include any unreleased commits, and to make sure those commits are able to make it onto a stable/train branch, releases were proposed by the Release Management team for any libs that looked like they needed it. We've had most of them +1'd by the team's PTL or release liaison and have been able to process those requests. There are still a few with no responses from the teams though. https://review.opendev.org/#/q/topic:train-3+status:open If you are a PTL or release liaison for one of the teams tagged in the subject line, please take a look and either +1 if things are ready, or if there are any last minute critical fixes going in, update the patches with a more appropriate commit hash to tag from. For any release requests not ack'd by the teams, we will need to proceed with these by Monday morning to make sure updates make it out and any dependency issues are flushed out before the client lib and other upcoming freezes. I will also submit patches to create the stable/train branch for any of these libs that have not already done so. If there are any questions or concerns about any of this, please reach out here or in the #openstack-release channel and we'll do what we can to help out. Thanks! Sean

[nova] Deprecating the XenAPI driver
by Matt Riedemann 06 Sep '19

06 Sep '19

After discussing this at the Train PTG and logging a quality warning in the driver 3 months ago [1] with no response, the nova team is now formally deprecating the XenAPI driver [2]. There has been no working third party CI for the driver for at least a release and no clear maintainers of the driver in nova anymore. If you're using the driver in production, please speak up now otherwise technically the driver could be removed as early as the Ussuri release.

[cinder][ops] Shanghai Forum - Cinder Topic Planning
by Brian Rosmaita 06 Sep '19

06 Sep '19

The Cinder Community would like to get in on some Forum action in Shanghai, but to do that we need to have some topics to propose. You don't have to actively be working on Cinder to propose a topic, and you don't have to be present to win. The point of the Forum sessions is to get feedback from operators and users about the current state of the software, get some ideas about what should be in the next release, and have some strategic discussion about The Future. So whether you can attend or not, if you have some ideas you'd like us to discuss, feel free to propose a topic: https://etherpad.openstack.org/p/cinder-shanghai-forum-proposals The deadline for proposals to the Foundation is 20 September, so if you could get your idea down on the etherpad before the Cinder weekly meeting on Wednesday 18 September 16:00 UTC, that will give the Cinder team time to look them over. thanks! brian

[tripleo] Proposing Damien Ciabrini as core on TripleO/HA
by Michele Baldessari 06 Sep '19

06 Sep '19

Hi all, Damien (dciabrin on IRC) has always been very active in all HA things in TripleO and I think it is overdue for him to have core rights on this topic. So I'd like to propose to give him core permissions on any HA-related code in TripleO. Please vote here and in a week or two we can then act on this. Thanks, -- Michele Baldessari <michele(a)acksyn.org> C2A5 9DA3 9961 4FFB E01B D0BC DDD4 DCCB 7515 5C6D

[goal][python3] Train unit tests weekly update (goal-1)
by Corey Bryant 06 Sep '19

06 Sep '19

This is the goal-1 weekly update for the "Update Python 3 test runtimes for Train" goal [1]. There is only 1 week remaining for completion of Train community goals [2]. == How can you help? == If your project has failing tests please take a look and help fix. Python 3.7 unit tests will be self-testing in Zuul. Failing patches: https://review.openstack.org/#/q/topic:python3-train +status:open+(+label:Verified-1+OR+label:Verified-2+) If your project has patches with successful tests please help get them merged. Open patches needing reviews: https://review.openstack.org/#/q/topic:python3 -train+is:open Patch automation scripts needing review: https://review.opendev.org/#/c/666934 == Ongoing Work == We're down to 8 projects with failing tests that need fixing, and 3 projects with successful tests that should be ready to merge. I've been working to contact PTLs for these projects to help finish them up. Thank you to all who have contributed their time and fixes to enable patches to land! == Completed Work == All patches have been submitted to all applicable projects for this goal. Merged patches: https://review.openstack.org/#/q/topic:python3-train +is:merged == What's the Goal? == To ensure (in the Train cycle) that all official OpenStack repositories with Python 3 unit tests are exclusively using the 'openstack-python3-train-jobs' Zuul template or one of its variants (e.g. 'openstack-python3-train-jobs-neutron') to run unit tests, and that tests are passing. This will ensure that all official projects are running py36 and py37 unit tests in Train. For complete details please see [1]. == Reference Material == [1] Goal description: https://governance.openstack.org/tc/goals/train/ python3-updates.html [2] Train release schedule: https://releases.openstack.org/train /schedule.html (see R-5 for "Train Community Goals Completed") Storyboard: https://storyboard.openstack.org/#!/story/2005924 Porting to Python 3.7: https://docs.python.org/3/whatsnew/3.7.html#porting-to-python-3-7 Python Update Process: https://opendev.org/openstack/governance/src/branch/master/resolutions/2018… Train runtimes: https://opendev.org/openstack/governance/src/branch/master/reference/runtim… train.rst Thanks, Corey

[monasca] Review Priority flag
by Witek Bedyk 06 Sep '19

06 Sep '19

Hello Team, now that we have the possibility to label our code changes with Review-Priority I would like to start the discussion about formalizing its usage. Right now every core reviewer can set its value, but we haven't defined any rules on how to use it. I suggest a process of proposing the changes which should be prioritized in weekly team meeting or in the mailing list. Any core reviewer, preferably from a different company, could confirm such proposed change by setting RV +1. I hope it's simple enough. What do you think? Another topic is exposing the prioritized code changes to the reviewers. We can list them using the filter [1]. We could add the link to this filter to Contributor Guide [2] and Priorities page [3]. We should also go through the list every week in the meeting. Any other ideas? Thanks Witek [1] https://review.opendev.org/#/q/(projects:openstack/monasca+OR+project:opens… [2] https://docs.openstack.org/monasca-api/latest/contributor/index.html [3] http://specs.openstack.org/openstack/monasca-specs/

[placement] update 19-35
by Chris Dent 06 Sep '19

06 Sep '19

HTML: https://anticdent.org/placement-update-19-35.html Let's have a placement update 19-35. Feature freeze is this week. We have a feature in progress (consumer types, see below) but it is not critical. # Most Important Three main things we should probably concern ourselves with in the immediate future: * We are currently without a PTL for Ussuri. There's some discussion about the options for dealing with this in an [email thread](http://lists.openstack.org/pipermail/openstack-discuss/2019-Septemb…. If you have ideas (or want to put yourself forward), please share. * We need to work on useful documentation for the features developed this cycle. * We need to create some [cycle highlights](http://lists.openstack.org/pipermail/openstack-discuss/2019-Sep…. To help with that I've started [an etherpad](https://etherpad.openstack.org/p/placement-train-cycle-highlights). If I've forgotten anything, please make additions. # What's Changed * osc-placement 1.7.0 has been [released](https://pypi.org/project/osc-placement/). This adds support for [managing allocation ratios](https://review.opendev.org/#/q/topic:allocation-ratios+(status:open… via aggregates, but adding a few different commands and args for inventory manipulation. * Work on consumer types exposed that placement needed to be first class in grenade to make sure database migrations are run. That [change has merged](https://review.opendev.org/679655). Until then placement was upgraded as part of nova. # Stories/Bugs (Numbers in () are the change since the last pupdate.) There are 24 (-1) stories in [the placement group](https://storyboard.openstack.org/#!/project_group/placement). 0 (0) are [untagged](https://storyboard.openstack.org/#!/worklist/580). 5 (0) are [bugs](https://storyboard.openstack.org/#!/worklist/574). 4 (0) are [cleanups](https://storyboard.openstack.org/#!/worklist/575). 11 (-1) are [rfes](https://storyboard.openstack.org/#!/worklist/594). 4 (0) are [docs](https://storyboard.openstack.org/#!/worklist/637). If you're interested in helping out with placement, those stories are good places to look. * Placement related nova [bugs not yet in progress](https://goo.gl/TgiPXb) on launchpad: 17 (0). * Placement related nova [in progress bugs](https://goo.gl/vzGGDQ) on launchpad: 6 (0). # osc-placement * <https://review.opendev.org/666542> Add support for multiple member_of. There's been some useful discussion about how to achieve this, and a consensus has emerged on how to get the best results. * `--amend` and `--aggregate` on resource provider inventory has merged and been release 1.7.0 (see above). # Main Themes ## Consumer Types Adding a type to consumers will allow them to be grouped for various purposes, including quota accounting. * <https://review.opendev.org/#/q/topic:bp/support-consumer-types> I took this through to microversion and api-ref docs, so it is ready for wider review. If this doesn't make it in for Train, that's okay. The goal is to have it ready for Nova to start working with it when Nova is able. ## Cleanup Cleanup is an overarching theme related to improving documentation, performance and the maintainability of the code. The changes we are making this cycle are fairly complex to use and are fairly complex to write, so it is good that we're going to have plenty of time to clean and clarify all these things. Performance related explorations continue: * <https://review.opendev.org/#/c/679385/> Refactor initialization of research context. This puts the code that might cause an exit earlier in the process so we can avoid useless work. One outcome of the performance work needs to be something like a _Deployment Considerations_ document to help people choose how to tweak their placement deployment to match their needs. The simple answer is use more web servers and more database servers, but that's often very wasteful. # Other Placement Miscellaneous changes can be found in [the usual place](https://review.opendev.org/#/q/project:openstack/placement+status:op…. * <https://review.opendev.org/676982> Merge request log and request id middlewares is worth attention. It makes sure that _all_ log message from a single request use a global and local request id. There are three [os-traits changes](https://review.opendev.org/#/q/project:openstack/os-traits+status:… being discussed. And zero [os-resource-classes changes](https://review.opendev.org/#/q/project:openstack/os-resource-class…. # Other Service Users This week (because of feature freeze) I will not be adding new finds to the list, just updating what was already on the list. * <https://review.opendev.org/662229> helm: add placement chart * <https://review.opendev.org/#/q/topic:bp/virtual-persistent-memory> libvirt: report pmem namespaces resources by provider tree * <https://review.opendev.org/660852> Nova: Remove PlacementAPIConnectFailure handling from AggregateAPI * <https://review.opendev.org/670112> Nova: WIP: Add a placement audit command * <https://review.opendev.org/671793> Nova: libvirt: Start reporting PCPU inventory to placement A part of <https://review.opendev.org/#/q/topic:bp/cpu-resources> * <https://review.opendev.org/#/q/topic:bp/support-move-ops-with-qos-ports> Nova: support move ops with qos ports * <https://review.opendev.org/667952> nova: Support filtering of hosts by forbidden aggregates * <https://review.opendev.org/670696> tempest: Add placement API methods for testing routed provider nets * <https://review.opendev.org/672678> openstack-helm: Build placement in OSH-images * <https://review.opendev.org/674129> Correct global_request_id sent to Placement * <https://review.opendev.org/#/q/topic:bp/cross-cell-resize> Nova: cross cell resize * <https://review.opendev.org/674524> Nova: Scheduler translate properties to traits * <https://review.opendev.org/623558> Nova: single pass instance info fetch in host manager * <https://review.opendev.org/#/q/topic:bp/provider-config-file> Nova: using provider config file for custom resource providers # End 🐎 -- Chris Dent ٩◔̯◔۶ https://anticdent.org/ freenode: cdent
