srwilkers_alright, lets go ahead and start tackling these then15:04
srwilkers_#topic Health Checks15:04
*** openstack changes topic to "Health Checks (Meeting topic: openstack-helm)"15:04
srwilkers_portdirect, i think you raised this topic last week or this one -- cant recall15:04
srwilkers_youve got the floor15:04
*** renmak_ has joined #openstack-meeting-515:05
portdirectyeah - I ve got a few queries about these - as I'm not sure we want to be killing/restarting pods when comms with infra is broken - seems like a way to create a runaway train. but was wondering if dulek had thought of somthing id missed?15:06
* dulek is here to answer any questions about the patches.15:06
portdirect:)15:06
dulekRight, that's something I was wondering about too.15:06
*** gomarivera has quit IRC15:06
dulekMy intention with the patches is also to have some indication for the admin that pod is unhealthy.15:07
dulekAlso I can imagine a pod being rescheduled to another kubelet, which resolves the problem if it was caused by physical network failure.15:07
portdirectyeah - though i can also see a transient problem causing the entire cluster to go down?15:08
*** f13o has quit IRC15:08
dulekPlease note that in case of Neutron and Nova, healthchecks are based on nova service-list/neutron agent-list commands. I was hoping to do the same with the rest of the charts but it isn't always possible.15:08
dulekportdirect: Pod restart when a transient failure occurred isn't really that bad thing IMO.15:09
portdirectit is if they all restart simultaneously - thats gonna potentially put a huge load on your underlying services15:10
dulekportdirect: Well, I cannot disagree with that.15:11
portdirectbut i get your point - would the visibility your aiming for not be better achived through a mechanism like centralised logging?15:11
dulekportdirect: Though if your infra is suffering from transient failures, you should probably tweak liveness probe period.15:12
*** korzen has joined #openstack-meeting-515:12
portdirect the best thing about failure is it s like the Spanish Inquisition: https://www.youtube.com/watch?v=sAn7baRbhx415:13
dulekportdirect: RabbitMQ or DB disconnections could be addressed through that, I'm not sure about monitoring "nova service-list" though.15:13
portdirectsrwilkers_: will the work your doing be able to monitor those things?15:14
srwilkers_portdirect, yeah. it should be able to.15:14
srwilkers_and once we actually get it into addons, we can start looking at specific exporters for prometheus and adjusting the rules as necessary15:14
portdirectwould you be able to work with dulek to get a list of the tings we'd need to monitor in a spec?15:15
srwilkers_sure, i can get that started today15:15
srwilkers_#action srwilkers: document appropriate monitoring targets with dulek15:16
portdirectdulek: would that work for you? I suspect it would need a combination of your work and srwilkers_ to get all we need15:16
dulekI'll be ending my office day just after the meeting, but I can definitely provide a list of alarms in logs/commands that we should look for.15:16
portdirectawesome - cheers dude15:17
dulekportdirect: Sure, I'll take a look at srwilkers_ work and see how we can use it.15:17
srwilkers_okay cool. think we can move on then?15:18
srwilkers_#topic Gating for Addons/Infra15:18
*** openstack changes topic to "Gating for Addons/Infra (Meeting topic: openstack-helm)"15:18
srwilkers_so we've got openstack-helm-addons and openstack-helm-infra now, in addition to the primary repo15:18
srwilkers_portdirect, lamt and StaceyF have been tossing around ideas for gating the three repos in a way that makes sense in how the repositories are expected to be used15:19
srwilkers_the current idea is to explore zuul-cloner to see how we can run checks on the three repos without introducing any race conditions or overhead15:20
lamtsrwilkers_ -infra was created overnight, I will work to set up the linter gate there, also to clean up -addons15:20
*** f13o has joined #openstack-meeting-515:20
srwilkers_lamt, awesome. i can help as well if you need. think that should be higher priority so we can start getting stuff out of the queue in addons15:21
srwilkers_theres already a bit backed up there15:21
lrensingjust for clarity, can we define where we draw the line for each of the repos?15:21
srwilkers_lamt, any other thoughts?15:21
lamtlamt for now, either tarball, or gitclone, will need to play around with it15:22
srwilkers_lrensing, sure. the expectation is that infra is anything required to run the openstack services on top of.  addons is anything ancillary that can be used in conjunction with them15:22
srwilkers_thats my view at any rate15:22
portdirect^^ ++15:22
lrensingsounds good :)15:22
srwilkers_lamt, awesome15:22
srwilkers_#action lamt to explore tarballs or gitclone for multi repo checks/gates15:23
portdirectlamt: id like us to use git clone when not in infra - being able to run the gate scripts locally is pretty important :)15:23
lamtthe linter should work for -addons, please review it.  will refine the node3 gate late15:23
lamtportdirect sounds good15:23
portdirectperhaps we should explore having an 'armada' check as well?15:25
portdirectalanmeadows: ^?15:25
alanmeadowsit supports remote git urls and branch/tag targets15:25
alanmeadowsseems like the fit you're after15:25
alanmeadowsI have a working manifest for ~master at this point15:26
portdirectnice - if we got an addtional 3 node check would you be able to submit a ps for it?15:26
alanmeadowssure15:27
srwilkers_alanmeadows, portdirect: awesome :)15:28
portdirectsounds good - I'll try and get that up today15:28
srwilkers_#action portdirect will look into 3 node check for armada check15:29
srwilkers_anything else on gating?15:29
*** f13o has quit IRC15:30
portdirectI'll be working with lrensing to get ceph running iin the gate today and start the road to dropping nfs :D15:30
srwilkers_portdirect, thatd be really awesome :)15:30
portdirectwe'll also have vms running in the gate soon - i just need to tidy up my ps15:30
portdirecthttps://review.openstack.org/#/c/474960/15:31
srwilkers_that's great. let's get some visibility on those when they're ready for review.  would be nice to get those in for sure15:31
StaceyFI put the 3rd party gate as a separate topic but can bring it up now?15:32
srwilkers_oh nice15:32
srwilkers_of course StaceyF, floors yours15:32
srwilkers_#topic Third Party Gate15:32
*** openstack changes topic to "Third Party Gate (Meeting topic: openstack-helm)"15:32
StaceyFIt's currently just a skeleton job but we have Openstack Helm deployed on our CI lab and will be utilizing Jenkins plugins (openstack-cloud) to dynamically provision VMs to test OSH on PS / merge in Gerrit15:33
StaceyFI'd like to get the go ahead to make it a non-voting 3rd party instead of the skipping once we've stabilized the Jenkins jobs15:34
*** zenirc369 has quit IRC15:34
StaceyFWe will be putting the logs on an Apache server so they are accessible to see failures/success.15:35
srwilkers_StaceyF, hmm. im okay with it becoming a non-voting 3rd party gate, given the logs are publicly available15:35
StaceyFsrwilkers thanks15:37
srwilkers_portdirect, thoughts?15:37
portdirectnice - will we be able to run rally properly inside the ATT gate?15:37
StaceyFyes15:37
portdirectsrwilkers_: think this is pretty awesome :)15:37
srwilkers_alright cool.15:38
StaceyFthen I'll move forward and will provide status as it moves along15:39
srwilkers_StaceyF, great. keep us posted :)15:39
srwilkers_#topic Monasca-Helm (https://github.com/monasca/monasca-helm)15:40
*** openstack changes topic to "Monasca-Helm (https://github.com/monasca/monasca-helm) (Meeting topic: openstack-helm)"15:40
srwilkers_i added this topic for jayahn as it was mentioned yesterday15:40
srwilkers_and he brought up possibly touching base with the monasca folks to see what their intentions are for it15:40
srwilkers_but im not sure if jayahn is present currently, so might want to follow up with him when i see him in the openstack-helm channel again.  i know the time difference is pretty drastic15:41
portdirectyeah - they have some interesting things going on over there - looks like a full stack in a single chart?15:41
srwilkers_portdirect, thats what it seems like at a glance15:42
srwilkers_i havent had a chance to play with it yet, but they're using monasca to grab cluster-level metrics i think and scraping prometheus endpoints15:42
portdirectbe good to chat to them for sure - you know what irc chan they in?15:42
srwilkers_i can dig it up and ask about it today15:42
srwilkers_either way, i think im going to fiddle with it and profile it versus prometheus to see what the differences are just for the sake of comparison15:43
srwilkers_#action srwilkers_ follow up with jayahn about monasca-helm15:44
srwilkers_#topic open discussion15:45
*** openstack changes topic to "open discussion (Meeting topic: openstack-helm)"15:45
srwilkers_alright, that's all the topics we had in the etherpad for today15:45
srwilkers_id like to open the floor for any other concerns/topics that weren't on the agenda15:45
srwilkers_going once15:47
*** gomarivera has joined #openstack-meeting-515:47
srwilkers_going twice?15:48
srwilkers_alright, going to give you all 10 minutes back15:49
