jheskethcorvus: the main reason I placed my WIP driver webhook patch where I did as I was playing around with an alternative to your patch with the intention of possibly squashing them together01:46
jheskeththe approach in 568028 felt hacky and not quite correct tbh01:47
jheskethbut I know it's because you want to get the cherrypy stuff in so if that's urgent enough to warrant this as an interim solution then sure01:48
openstackgerritTristan Cacqueray proposed openstack-infra/nodepool master: Implement an OpenContainer driver  https://review.openstack.org/53555603:08
dmsimard|offcorvus: the mqtt reporter from tristanC has two +2s, does it need anything else ? I'd love to enable that to publish messages on firehose.03:34

SpamapSShrews: are you coming to YVR? I'd really like to find a quiet corner and show you how our nodepool gets locked up if you are.04:39
SpamapScorvus: or maybe you'd like to try your hand too? or really anybody04:39
SpamapSit just gets.. stuck.04:39
SpamapSand then unsticks itself04:39
tristanCSpamapS: perhaps your executor is too busy to complete node requests?04:53
tobiashSpamapS: I'll be there and happy to help05:12
*** snapiri has joined #zuul05:58
SpamapStristanC: no this is all nodepool06:33
SpamapSIt gets stuck with many requests and many nodes ready, and it does nothing06:33
SpamapSuntil it does.. many many minutes later06:33
tristanCbut are there jobs running when this happen?06:36
tristanCor even merge job keeping the executor busy06:37
SpamapStristanC: yes06:39
SpamapSa few running, and a few queued06:39
SpamapStristanC: my load is so tiny06:40
SpamapSI run on a single 16GB VM.06:40
SpamapSwith 8 vcpu's06:40
SpamapSThe queued ones are the ones that are frustrating06:40
tristanCSpamapS: iirc, nodepool may appear to be stuck when it may be the executor simply too busy to accept node requests06:42
tristanCin statsd, you can verify that the executors queues are empty06:42
SpamapSI don't have statsd.06:42
SpamapSBut it's a plausible theory06:43
tristanCespecially if executor are doing merger jobs too06:44
SpamapSIt's just not that busy06:47
SpamapSbut yeah maybe things are queueing up in there06:47
SpamapSBeen meaning to get a statsd going06:47
tristanCyeah, that would be useful :-)06:47

tobiashSpamapS: in order to check if tristanC is right you might also want to look for governor related messages in the zuul-executor as it throttles itself under high load or memory pressure07:26

dmsimard|offa question for ARA users - would you like it if the task tab defaulted to filtering out 'ok' and 'skipped' tasks ? So that only changed/failed/unreachable showed. This filter could be cleared -- it'd be just a default value for the search box, basically.13:03

mordredcorvus: with the WIP off, I'm assuming those are ready for review now yeah?14:38
corvusmordred: i thought so, but there's still a non-trivial test failure; it'll need at least one more revision14:42
mordredcorvus: kk. I left a note on the first patch for you14:45
corvusmordred: replied!14:48
corvuswe should probably call that thing the DriverRegistry instead of ConnectionRegistry14:49
mordredcorvus: nod. and yes- I thnk we should rename that -it's unsettling to read :14:51

Shrewshow interesting that someone implemented a kubernetes driver for nodepool and didn't bother to tell us  :)15:58
pabelangeroh? Where did you see that16:04
Shrewspabelanger: https://www.openstack.org/summit/vancouver-2018/summit-schedule/events/21177/devops-implementation-for-openstack-on-kubernetes16:07
SpamapStobiash: no governor firing.16:09
SpamapSAlso I don't think the executor would be the issue.. the nodes aren't even claimed.. they're ready/unlocked ... so how would the executor cause that?16:09
SpamapSAlso if i restart nodepool-launcher, the requests suddenly get satisfied.16:10
pabelangerShrews: look at that, hopefully they decide to work upstream on the open spec16:11
corvuswe can chat with them next week :)16:11
fungihuh... anybody (besides me) noticed yet that the release notes aren't in any sane order? https://zuul-ci.org/docs/zuul/releasenotes.html16:12
fungiwonder if that's some quirk of reno we're not aware of16:13
pabelangercorvus: ++16:13
corvusfungi: it's fixed in reno, lets see if it's released16:13
fungiaha, glad to know i'm not the first to trip over it16:14
corvusfungi: released yesterday; so next doc build should fix it16:14
fungiexcellent timing16:14
*** gtema has quit IRC16:19
tobiashSpamapS: that definitely sounds like nodepool is the problem16:20
tobiashMaybe the handlers are paused because of some reason16:21
SpamapSI do wonder if it's something weird like a deadlock that gets resolved by a timeout, quietly.16:21
corvusSpamapS: i'd add lots of debug statements, then upstream the ones used to solve the problem16:22
SpamapScorvus: yeah, that's what I hope to find some time to do.16:23
SpamapSUsually I just bounce nodepool launcher and move on with my day.16:23
SpamapSBut I dislike the icky feeling of windows admin sickness it brings. ;)16:23

corvusdmsimard: i expect it's ready to go; i'm personally not keen on landing big changes this week.  i'm swamped with summit prep.20:07
dmsimardcorvus: fair, thanks20:08
corvusfungi: dns changes lgtm!20:12
fungicorvus: thanks, didn't know if you would be okay with adding more domains in the zones tree within that repo20:15
corvusfungi: yeah, i think that makes sense in this case20:15
corvusfungi: (though, if infra starts hosting non-zuul related domains, i think they should get their own repo(s))20:16
openstackgerritMerged openstack-infra/zone-zuul-ci.org master: Add zuulci.org typo domain  https://review.openstack.org/56866120:16
fungiit seemed like a reasonable compromise since the only domain we really care about there is the one for which the repo is named, and the other one is just  a husk20:16
corvusfungi: i mean, apparently we thought ahead and named the directory "zones" :)20:18
fungii saw!20:18
