[openstack-dev][tripleo] TripleO CI Summary: Sprint 22
by Rafael Folco 30 Nov '18

30 Nov '18

Greetings, The TripleO CI team has just completed Sprint 22 (Nov 08 thru Nov 28). The following is a summary of completed work during this sprint cycle: - Converted multinode scenarios(1-4) to standalone job. This effort will allow us to replace multinode scenario jobs that are consuming most of upstream resources. Replacement of multinode scenario jobs is starting immediately and should be complete by Jan 2019. - Improved python and ansible support on Fedora 28 job, which is successfully deploying TripleO, but still requires further work on Tempest packaging before becoming a voting job. This is the first step in using upstream CI to validate python3 and RHEL8 work. - Investigated alternative solutions for the reproducer to approximate with the zuulv3 workflow. A PoC has been developed to run Zuul in a container as the reproducer script for TripleO CI. - Tested a new CI environment for OVB jobs on RDO cloud. Experiments for refectoring ovb deployment to be incorporated into CI code without te-broker bits. - https://tree.taiga.io/project/tripleo-ci-board/epic/298 - Initial testing of CentOS 7.6 looks good - https://tree.taiga.io/project/tripleo-ci-board/issue/309?kanban-status=2027… The sprint task board for CI team is tracked on Taiga [1] and the Ruck and Rover notes for this sprint has been tracked in the etherpad [2]. The planned work for the next sprint focuses in completing the upstream standalone job for Fedora 28 by eliminating all related issues. It also includes moving the multinode scenarios to the standalone jobs that has started in the previous sprint. The team continues to work on the reproducer and preparing a CI environment for OVB. The only new item for the sprint is to start building the production pipeline promotion jobs for Fedora 28. The Ruck and Rover for this sprint are Marios Andreou (marios) and Sorin Sbarnea (ssbarnea). Please direct questions or queries to them regarding CI status or issues in #tripleo, ideally to whomever has the ‘|ruck’ suffix on their nick. Thanks, Folco [1] https://tree.taiga.io/project/tripleo-ci-board/taskboard/sprint-23unified-s… [2] https://review.rdoproject.org/etherpad/p/ruckrover-sprint22 -- Rafael Folco Senior Software Engineer

[placement] update 18-48
by Chris Dent 30 Nov '18

30 Nov '18

HTML: https://anticdent.org/placement-update-18-48.html Here's a placement update. It's been a rather busy week in placement-land: Gibi and I, with the help of others, have been getting the functional tests in nova working with an external placement. It is working now, which is great, but much work was done, more details within. # Most Important Progress continues on the work in ansible, puppet/tripleo, kolla, loci to package placement up and establish upgrade processes. All of these things need review (see below). Work on GPU reshaping in virt drivers is getting close. # What's Changed * Devstack installs placement from openstack/placement, not nova. * Placement now runs tempest and grenade (in py3) in CI. This is great because real integration tests and sad because our once really fast CI runs are gone. * The placement service can now start without a conf file. This is basically fixing a bug: we required a single config file in a specific location, rather than the defaults (which includes no file). We require an explicit database connection. # Bugs * Placement related [bugs not yet in progress](https://goo.gl/TgiPXb): 19. +2. * [In progress placement bugs](https://goo.gl/vzGGDQ) 14. +1 # Specs Spec freeze is milestone 2, the week of January 7th.

Horizon Logging Question
by sam.bouwari＠verizon.com 30 Nov '18

30 Nov '18

Hello Horizon Proj Developers. In previous (older) Openstack/Horizon versions (version 7 or 8), the /var/log/horizon.log file used to reveal "remote address" information when a user attempts to login to Horizon GUI with wrong password, or if someone is trying to guess a password, then a log entry similar to this would be logged: 2018-11-01 19:39:35,728 3711 WARNING openstack_auth.forms Login failed for user "admin", remote address 192.168.1.12. In newer OSP/Horizon versions, the "remote address" field seems to have been truncated from the log and all we see now is a login entry in /var/log/horizon.log similar to this: 2018-11-30 14:23:10,912 473292 WARNING openstack_auth.forms Login failed for user "admin". Is there any valid reason as to why this feature was removed from newer version of Horizon? Logging the "remote address" information is very useful from security/IR and log monitoring standpoint where an analyst can identify if someone is trying to guess passwords, or trying to brute force the Horizon GUI, and other useful scenarios. Is there a configuration parameter in Horizon that can be turned on to log the "remote address" infromation again? Or is this feature just not available anymore in the product? Your help is greatly appreciated! Thanks Sam Bouwari

# Keystone Team Update - Week of 26 November 2018 ## News ### Forum Recap Two weeks ago some of us attended the OpenStack Summit in Berlin, where we had a couple of keystone-specific sessions and had some discussions with Edge computing operators and public cloud operators about keystone use cases. Lance wrote up a recap[1]. [1] https://www.lbragstad.com/blog/openstack-summit-berlin-recap ### Refreshable application credentials We had a short discussion on how refreshable application credentials will be implemented[2]. The summary is that new fields should be added to the existing model, renewed_at and renewable_roles. We had discussed adding a new expiration field or reusing the existing expiration field, but decided that for the refresh use case, application credentials shouldn't be using expiration but instead a static comparison of the last refresh time and a configurable TTL tied to the IdP. The existing expiration field will remain user-configurable.

Re: [Openstack] [Pike][Neutron] L3 metering with DVR doesn't work
by Alexandru Sorodoc 30 Nov '18

30 Nov '18

Hello Brian, Thanks for the info. I looked into the code for the metering agent and discovered the following: 1. The metering agent on compute nodes doesn't get notified about DVR routers running on the node. 2. For DVR routers it tries to meter the rfp- interface(for floating ips) on the snat- namespace. This is wrong. The rfp- interface lies on the qrouter- namespace on compute nodes. Also, there is a qg- interface on the snat- namespace on network nodes (for performing NAT) which should be metered too. 3. There is a race condition whereby the metering agent is notified about a router before its namespaces are created. The agent ends up not adding the metering rules for those namespaces and this leads to unrecorded traffic. I addressed those issues in a change: https://review.openstack.org/#/c/621165/. Any feedback is appreciated.

[oslo][nova][stable][requirements] Fixing a high CPU usage from oslo.service into stable/rocky branch
by Herve Beraud 30 Nov '18

30 Nov '18

Hey all! Here is a thread to coordinate all the teams (oslo, nova, stable, requirements) working on the update of the oslo.service constraint in the Rocky requirements. # Summary Usage of threading event with eventlet caused inefficient code (causing many useless system calls and high CPU usage). This issue was already fixed on oslo.service master and we also want to fix it in stable/rocky. Our main issue is how to fix the high CPU usage on stable/rocky without break the nova CI. Indeed, we already have backported the eventlet related fix to oslo.service but this fix requires also a nova update to avoid nova CI errors due to threading removal on oslo.service that introduce the nova CI errors. A fix was proposed and merged on oslo.service master to introduce a new feature (fixture) that avoid the nova CI errors, but backporting the master fix to Rocky introduces a new feature into a stable branch so this is also an issue. So we need to discuss with all the teams to find a proper solution. # History A few weeks ago this issue was opened on oslo.service ( https://bugs.launchpad.net/oslo.service/+bug/1798774) and it was fixed by this submited patch on the master branch ( https://review.openstack.org/#/c/611807/ ). This change use the proper event primitive to fix the performance issue. A new version of oslo.service was released (1.32.1) Since these changes was introduced into oslo.service master, nova facing some issues into the master CI process, due to the threading changes, and they was fixed by these patches ( https://review.openstack.org/#/c/615724/, https://review.openstack.org/#/c/617989/ ) into master. Few weeks ago I have backport to oslo.service some changes ( https://review.openstack.org/#/c/614489/ ) from master to stable/rocky to also fix the problem in the rocky release. When this backport was merged we have created a new release of oslo.service (1.31.6) ( https://review.openstack.org/#/c/616505/ ) (stable/rocky version). Then the openstack proposal bot submit a patch to requirements on stable rocky to update the oslo.service version with the latest version (1.31.6) but if we'll use it we'll then break the CI https://review.openstack.org/#/c/618834/ so this patch is currently blocked to avoid nova CI error. # Issue Since the oslo.services threading changes were backported to rocky we risk to faces the same issues inside the nova rocky CI if we update the requirements. In parallel in oslo.service we have started to backport a new patch who introduces fixture ( https://review.openstack.org/#/c/617989/ ) from master to rocky, and also we start to backport on nova rocky branch ( https://review.openstack.org/619019, https://review.openstack.org/619022 ) patches who use oslo.service.fixture and who solve the nova CI issue. The patch on oslo.service exposes a public oslo_service.fixture.SleepFixture for this purpose. It can be maintained opaquely as internals change without affecting its consumers. The main problem is that the patch bring a new functionality to a stable branch (oslo.service rocky) but this patch help to fix the nova issue. Also openstack proposal bot submit a patch to requirements on stable rocky to update the oslo.service version with the latest version (1.31.6) but if we'll use it we'll then break the CI https://review.openstack.org/#/c/618834/ since the oslo service 1.31.6 is incompatible with novas stable rocky unittest due to the threading changes. # Questions and proposed solutions This thread try to summarize the current situation. We need to find how to be able to proceed, so this thread aim to allow to discuss between team to find the best way to fix. 1. Do we need to continue to try to backport fixture on oslo.service to fix the CI problem (https://review.openstack.org/#/c/617989/) ? 2. Do we need to find an another approach like mocking oslo.service.loopingcall._Event.wait in nova instead of mocking oslo_service.loopingcall._ThreadingEvent.wait (example: https://review.openstack.org/#/c/616697/2/nova/tests/unit/compute/test_comp…) ? This is only a fix on the nova side and it allows us to update oslo.service requirements and allows us to fix the high CPU usage issue. I've submit this patch (https://review.openstack.org/619246) who implement the description above. Personaly I think we need to find an another approach like the mocking remplacement (c.f 2). We need to decide which way we use and to discuss about other solutions. -- Hervé Beraud Senior Software Engineer Red Hat - Openstack Oslo irc: hberaud -----BEGIN PGP SIGNATURE----- wsFcBAABCAAQBQJb4AwCCRAHwXRBNkGNegAALSkQAHrotwCiL3VMwDR0vcja10Q+ Kf31yCutl5bAlS7tOKpPQ9XN4oC0ZSThyNNFVrg8ail0SczHXsC4rOrsPblgGRN+ RQLoCm2eO1AkB0ubCYLaq0XqSaO+Uk81QxAPkyPCEGT6SRxXr2lhADK0T86kBnMP F8RvGolu3EFjlqCVgeOZaR51PqwUlEhZXZuuNKrWZXg/oRiY4811GmnvzmUhgK5G 5+f8mUg74hfjDbR2VhjTeaLKp0PhskjOIKY3vqHXofLuaqFDD+WrAy/NgDGvN22g glGfj472T3xyHnUzM8ILgAGSghfzZF5Skj2qEeci9cB6K3Hm3osj+PbvfsXE/7Kw m/xtm+FjnaywZEv54uCmVIzQsRIm1qJscu20Qw6Q0UiPpDFqD7O6tWSRKdX11UTZ hwVQTMh9AKQDBEh2W9nnFi9kzSSNu4OQ1dRMcYHWfd9BEkccezxHwUM4Xyov5Fe0 qnbfzTB1tYkjU78loMWFaLa00ftSxP/DtQ//iYVyfVNfcCwfDszXLOqlkvGmY1/Y F1ON0ONekDZkGJsDoS6QdiUSn8RZ2mHArGEWMV00EV5DCIbCXRvywXV43ckx8Z+3 B8qUJhBqJ8RS2F+vTs3DTaXqcktgJ4UkhYC2c1gImcPRyGrK9VY0sCT+1iA+wp/O v6rDpkeNksZ9fFSyoY2o =ECSj -----END PGP SIGNATURE-----

Re: [openstack-dev] [vitrage] I have some problems with Prometheus alarms in vitrage.
by Won 30 Nov '18

Hi, I attached four log files. I collected the logs from about 17:14 to 17:42. I created an instance of 'deltesting3' at 17:17. 7minutes later, at 17:24, the entity graph showed the dentesting3 and vitrage colletor and graph logs are appeared. When creating an instance in ubuntu server, it appears immediately in the entity graph and logs, but when creating an instance in computer1 (multi node), it appears about 5~10 minutes later. I deleted an instance of 'deltesting3' around 17:26. > After ~20minutes, there was only Apigateway. Does it make sense? did you > delete the instances on ubuntu, in addition to deltesting? > I only deleted 'deltesting'. After that, only the logs from 'apigateway' and 'kube-master' were collected. But other instances were working well. I don't know why only two instances are collected in the log. NOV 19 In this log, 'agigateway' and 'kube-master' were continuously collected in a short period of time, but other instances were sometimes collected in long periods. In any case, I would expect to see the instances deleted from the graph at > this stage, since they were not returned by get_all. > Can you please send me the log of vitrage-graph at the same time (Nov 15, > 16:35-17:10)? > Information 'deldtesting3' that has already been deleted continues to be collected in vitrage-graph.service.

[ironic] Finding a time to discuss cleaning/deployment steps visibility
by Julia Kreger 30 Nov '18

30 Nov '18

Greetings everyone, As discussed previously, I'd like to find a time when we can get on a higher bandwidth medium to discuss making clean and deployment steps visible. Generally we've struggled to gain consensus and I'd like for us to focus on trying to reach a minimally viable feature. I've created a doodle at: https://doodle.com/poll/yan4wyvztf7mpq46 Most recent specification: https://review.openstack.org/#/c/606199/ -Julia

[all] [infra] StoryBoard Migration: The Remaining Blockers Summary
by Kendall Nelson 30 Nov '18

30 Nov '18

Hello! As with all of my other summaries, if you are looking for the long etherpad version, you can find it here[1]. Somewhere along the way I used the wrong etherpad for notes and so we ended up doing the StoryBoard things in the etherpad originally meant for another session so pardon the name. Anywho. Overall the session went really well, there weren’t any huge glaring issues that anyone brought up. The majority of things were all smaller usability things. Just about all of which are definitely doable. The only slightly larger feature request (that we hadn't previously discussed) was a separate interface for filing stories- similar to the one LP provides. Something simple so the user doesn’t feel like they need to fill in all this information, but can just provide the minimum. I haven’t quite gotten around to making stories for all of the things discussed in the etherpad, but should have them up soon! You will be able to see them here[2], once they’ve been created. If you have opinions about any of what we discussed or have something you wanted to bring up but could not attend the session please drop into #storyboard and chat with us, or join us at our weekly meeting on Wednesday at 19:00 UTC. -Kendall (diablo_rojo) [1]https://etherpad.openstack.org/p/BER-Contrib-Portal-Feedback (yes, I know the name doesn’t seem right..)
