ifat_afek#topic Status and Updates08:05
*** openstack changes topic to "Status and Updates (Meeting topic: vitrage)"08:05
ifat_afekNew releases were created for vitrage, based on stable/pike:08:05
ifat_afekvitrage 1.8.208:05
ifat_afekpython-vitrage client 1.4.008:05
ifat_afekThe Sydney summit is next weeks. There will be two sessions about Vitrage:08:06
ifat_afek#link https://www.openstack.org/summit/sydney-2017/summit-schedule/events/19508/advanced-fault-management-with-vitrage-and-mistral08:06
ifat_afek#link https://www.openstack.org/summit/sydney-2017/summit-schedule/events/19473/vitrage-project-updates08:06
ifat_afekI’m almost done preparing the Vitrage-Mistral demo. Now working on the presentations.08:06
ifat_afekAs part of preparing the demo, I found a few bugs:08:06
ifat_afek1.UI (already fixed by Alon): in the entity graph when selecting a specific Heat stack, the alarm icons were changed to heat stack icons08:07
ifat_afek2. UI (already fixed by Alon): in the entity graph properties area, the name was missing, and the user could see the internal is_real_vitrage_id flag08:07
ifat_afek3. The UI shows placeholder entities. Not sure why. It seems like a new bug.08:07
ifat_afekThis bug has two parts actually – one is to change the API query, and the other is to identify why we have placeholder vertices (this is supposed to be a temporary situation).08:07
ifat_afekIt is related to neutron.port datasource. The transformer assumes that the port neighbor is always an instance, but apparently this is not the case.08:08
ifat_afek1.Then, placeholder/dummy instances are created and stay in the graph.08:08
ifat_afekThe last “1” was a mistake08:08
ifat_afekA more significant issue that I realized is that the integration with Mistral is lacking.08:08
ifat_afekCurrently, in the template file you can ask to execute a workflow with specific pre-defined parameters. But you can not pass a dynamic parameter, like the current instance.08:08
ifat_afekI’ll create a blueprint for that, probably after I’m back from Sydney08:09
ifat_afekThat’s it for me08:09
annarezI'll update08:10
annarezI'm working on adjusting Vitrage to networkx 2.0 with backward compatibility to 1.1<networkx<2.008:10
annarezApparently the networkx teem published very good documentation for the new version08:10
annarezwe have open bug on this https://bugs.launchpad.net/openstack-requirements/+bug/171857608:11
openstackLaunchpad bug 1718576 in Solar "Handle networkx 2.0 update" [Undecided,In progress] - Assigned to Rajat Sharma (tajar29)08:11
annarezthat's it :)08:11
idan_hefetzmy update08:12
idan_hefetzParallel template evaluation is merged, default number of workers is currently 1, but we may wish to change this later on.08:12
idan_hefetzTo configure this, under [evaluator] add workers=x08:12
idan_hefetzbtw, thanks for the reviews :)08:13
ifat_afekThanks for the change ;-)08:13
idan_hefetzI still have two issue to solve, and to add documentation08:13
idan_hefetzthat it08:14
idan_hefetzthat's it08:14
ifat_afekThanks. Anyone else?08:15
*** pcaruana has joined #openstack-meeting-408:17
ifat_afekBTW, I suggest that in the next meeting we go over the roadmap and tasks that we decided on in the PTG, and check the current status08:18

duonghqfirst one is quite simple16:07
duonghqI get this bug many time: https://bugs.launchpad.net/kolla-ansible/+bug/172924616:07

Jeffrey4lduonghq, mariadb changed some thing recently.16:08
*** caboucha has joined #openstack-meeting-416:08

duonghqthank Jeffrey4l16:09
Jeffrey4lcuriosity upgrade is failed.16:10
Jeffrey4lanyway, i will check this.16:10
Jeffrey4lthank you for pointing this out.16:10
duonghq:)16:11
Jeffrey4lbtw, there is another old bug report that possible data loss during mariadb recovery.16:11
Jeffrey4lhttps://bugs.launchpad.net/kolla-ansible/+bug/168215316:11
openstackLaunchpad bug 1682153 in kolla-ansible "mariadb_recovery is prone to data loss" [Critical,Confirmed]16:11
duonghqsure, I saw that, seem that Sam proposed a fix for the bug16:12
rfxnthat bug has bitten me before, that articulate bug report helped narrow down and recover cluster16:12
Jeffrey4lno patch right now16:12
Jeffrey4lbut he propose a possible solution way in the description.16:12
duonghqwe should implements his proposal16:13
Jeffrey4lyes.16:13
duonghqthan let it roll for awhile16:13
Jeffrey4lokay. please move on16:14
duonghqsure,16:14
duonghqso, my 2nd topic is about Kolla-ansible HA layer16:14
duonghqdo anybody know why we use haproxy/keepalived for HA layer?16:15
duonghqbut not pacemaker/corosync stack16:15
Jeffrey4lduonghq, pacemaker/corosync is more complicated.16:15
rfxnfar more complicated16:15
*** chyka has joined #openstack-meeting-416:16
Jeffrey4land iirc, pacemaker can not be containerized before ( now it should work )16:16
duonghqbut it provides some mechanism for react with the failure, like data plane evacuation16:16
duonghqit is invaluable feature (IMO)16:17
*** salv-orlando has joined #openstack-meeting-416:17
Jeffrey4lduonghq, yes. pacemaker is powerful than keepalived. but what kind of issue we are facing by using keepalived.16:17
duonghqit just for add some functionality to our stack,16:18
duonghqI'm thinking in implement pacemaker into Kolla and let user choose which HA stack they want to use16:18
Jeffrey4lthat will be cool. pacemaker can handle more than keepalived.16:19
*** gema has left #openstack-meeting-416:19
duonghqJeffrey4l, so, I'll create a blueprint for this, is it ok?16:20
duonghqand try to containerized pacemaker (again)16:20
Jeffrey4lbut i just afraid what it will take to Kolla. more better health check? or fail over?16:20
*** Sukhdev has quit IRC16:20
Jeffrey4lsure. a blueprint is necessary for others to evaluate the possibility.16:21
duonghqabout healthcheck, I'm not sure only it can make Kolla better16:21
rfxnpacemaker in kolla feels like a solution to a problem that doesn't yet exist; granted from a maturity standpoint eventually moving to pacemaker from keepalived is probably what needs to happen16:21
duonghqbut I'm certainly about failover16:21
*** salv-orlando has quit IRC16:21
Jeffrey4lplease write what you think and the benefit.16:22
duonghqsure16:22
Jeffrey4lrfxn, tbh, i will current keepalived is enough. ;)16:23
Jeffrey4li think*16:24
Jeffrey4lbut who know what duonghq will take16:24
rfxncurrent, ya i think keepalived is more than enough -- time could be better spent on other areas of HA and Disaster Recovery instead of pacemaker atm16:24
*** chyka_ has joined #openstack-meeting-416:24
duonghqI think we can let user choose which stack they like,16:24
*** Rockyg has joined #openstack-meeting-416:25
duonghqrfxn, can you suggest some area?16:25
rfxnMariaDB is treated emphemeral right now, we put it behind a galera cluster and smile16:25
rfxnin reality, if you loose mysql data, your done16:25
rfxnwe need a reliable, backup strategy for mariadb16:25
rfxnclustering = HA, backup = DR16:26
*** eN_Guruprasad_Rn has quit IRC16:26
*** diablo_rojo_phon has joined #openstack-meeting-416:26
Jeffrey4lrfxn, are u meaning use pacemaker as DR solution?16:27
duonghqI'm thinking it is slightly out of scope of Kolla16:27
*** chyka has quit IRC16:28
*** serlex has joined #openstack-meeting-416:28
rfxnJeffrey4l, no, im all for keepalive (now) and pacemaker (later, as a maturity point); duonghq asked some area to suggest, my thought is lack of backup solution for mariadb is the largest, most volatile gap, currently16:28
Jeffrey4lah, got.16:29
Jeffrey4ldb backup is really necessary.16:29
Jeffrey4lso please register a bp for this duonghq , and let us discuss base on the bp.16:30
Jeffrey4lthanks16:30
Jeffrey4lthen any other topics?16:31
duonghqJeffrey4l, sure16:31
rfxnhappy to help discuss and lay out options in that bp16:31
duonghqthank you rfxn16:31
Jeffrey4lguess no topic.16:32
rfxnhttps://blueprints.launchpad.net/kolla/+spec/database-backup-recovery <- related16:32
duonghqrfxn, ah, it should be in kolla-ansible16:32
duonghqhow do you think, Jeffrey4l16:32
Jeffrey4lsure.16:32
Jeffrey4land xtrabackup should be the best solution.16:32
Jeffrey4lthe backup should run periodic.16:32
rfxnagreed xtrabackup/innobackupx with a few output options = win16:33
rfxntwo smaller items; updating haproxy from 1.5 to 1.716:33
Jeffrey4land we can add this jobs into cron containers. and save the backups into a new docker volumes.16:33
rfxnand letsencrypt for automagick issuance of external_fqdn ssl certs16:34
Jeffrey4lrefer to backup, there are other ways to backup. like ceph pg map, crush rule.16:35
Jeffrey4lrfxn, what upgrade haproxy?16:35
Jeffrey4lwhat/why16:35
rfxn1.7 offers better ssl termination, http2, more advanced acl features, far more performant16:35
Jeffrey4lrfxn, letencrypt may be hard. because during sign new certs, it requires network connective and a public domain.16:36
Jeffrey4lrfxn, basically, package version in kolla based on the linux distro repo.16:37
*** slaweq has joined #openstack-meeting-416:37
rfxni dont think those are blockers, most production deployments are going to be on an external fqdn  w/ internet access16:37
rfxni have a poc with haproxy that routes letsencrypt CA challenge/response to a dedicated listener on network group systems16:37
rfxnso it never needs to touch the horizon container16:38
rfxnletsencrypt is a nice to have,  maybe not a need to have :)16:38
Jeffrey4lyep16:39
rfxnbut would minimize the barrier to entry on new deployments imo16:39
duonghqrfxn, can you elaborate your point? about new deployments16:40
Jeffrey4land we can implement this in "kolla-ansible certifications" command.16:40
*** slaweq has quit IRC16:42
rfxnSSL certificates, valid browser recognized CA certificates, are the norm on any production ready deployment. Right now, managing SSL certificates is a pain, prone to human error and nothing should ever be internet facing without a valid cert.16:42
rfxnletsencrypt allows us to automate the process entirely, in very trivial way16:42
Jeffrey4lletsencrypt is a gread service ;p16:43
duonghqrfxn, thank you for teach me this16:43
Jeffrey4lgreat*16:43
*** csun_ has joined #openstack-meeting-416:43
rfxnnot trying to preach, just speak aloud that imo automagick ssl certificates would set kolla apart and remove a human error prone component for the stack16:43
rfxne.g azure going down cause of forgetting to renew api connector certs :P16:43
Jeffrey4llol16:44
Jeffrey4lrfxn, will you add such feature into kolla?16:44
*** csun has quit IRC16:45
*** csun_ is now known as csun16:45
rfxni can bp it16:45
rfxnand we go from there16:46
Jeffrey4lcool. thanks.16:46
rfxnand happy to share out my ugly code as poc :)16:46
Jeffrey4lrfxn, thanks for sharing ;D16:46
Jeffrey4lany other topics?16:47
duonghqrfxn, poc is always has many idea16:47
Jeffrey4lguess no. let us end the meeting.16:48
