srwilkers#startmeeting openstack-helm15:00
openstackMeeting started Tue Jul 18 15:00:30 2017 UTC and is due to finish in 60 minutes.  The chair is srwilkers. Information about MeetBot at http://wiki.debian.org/MeetBot.15:00
openstackUseful Commands: #action #agreed #help #info #idea #link #topic #startvote.15:00
*** openstack changes topic to " (Meeting topic: openstack-helm)"15:00
openstackThe meeting name has been set to 'openstack_helm'15:00
srwilkersgood morning o/15:00
duleko/15:01
lrensingo/15:01
portdirectoh hai \o15:01
xekhi o/15:01
srwilkersheres the link for today's agenda -- it's fairly light, probably in part to me not getting it out in a timely manner15:01
srwilkershttps://etherpad.openstack.org/p/openstack-helm-meeting-2017-07-1815:01
srwilkersthat'll be different for next week15:02
*** raymaika has joined #openstack-meeting-515:02
srwilkerslets take a few minutes and see if we can add some more points to it15:02
v1k0d3no/15:02
srwilkershey v1k0d3n o/15:02
raymaikahey guys o/15:02
v1k0d3non phone though so very limited. Still transitioning...moving this week.15:03
alraddarlao/15:03
srwilkersalright, we can get started and just open for discussion and see what else comes up after what's in the agenda15:05
srwilkers#topic LMA spec15:05
*** openstack changes topic to "LMA spec (Meeting topic: openstack-helm)"15:05
srwilkersi drafted a spec for an LMA approach for openstack-helm, and can be found here: https://review.openstack.org/#/c/482687/15:05
srwilkersid really like some additional operations-focused feedback on what's there so far15:06
dulekWhile I cannot provide much ops feedback on that, I sign up for reviews and testing of the implementation.15:07
srwilkersawesome dulek. :)15:07
srwilkersonce we get some more feedback on the spec and can identify some solid operational requirements for configuration, it'll make tying up some of the services that are in flight much easier15:09
srwilkersand also welcome those interested in helping get them to the finish line if anyones interested in contributing on that front15:10
alraddarla\o/15:10
srwilkersthats all ive got for this topic, unless there are other points someone would like to raise :)15:11
srwilkers#topic Memcached resiliency15:12
*** openstack changes topic to "Memcached resiliency (Meeting topic: openstack-helm)"15:12
*** mattmceuen has joined #openstack-meeting-515:12
srwilkersfloors yours xek15:12
xekalanmeadows pointed me to an issue with memcached which I would like to work on15:13
xekthe issue is that memcached is not clustered in any way right now15:13
xekI wanted to bring the blueprint to your attontion so that there is a consensus in the right solution15:13
xekin short, I want to introduce mcrouter into the mix and change the defaults so that all services point to mcrouter15:14
xekit can then be configured to talk to more then one memcached instance in any way which is desired by the operator15:14
xekto meet distribution and ha requirements15:14
portdirectsounds sane15:15
portdirectreading bp now15:15
dulekI can see that "official" chart uses just a service for load balancing: https://github.com/kubernetes/charts/tree/master/stable/memcached15:15
dulekxek: Is what you're proposing a better idea?15:15
v1k0d3ntoo bad we're not just using upstream for some things like this.15:16
portdirectI would have thought so - a service really has limitations here15:16
v1k0d3nbut control can be an issue too. i see both sides.15:16
portdirectand does not really do what we need15:16
dulekOkay, I see no replication in this upstream chart, so it's rather poor15:17
xekdulek, with default round-robin balancing you can wind up in a situation where you only use one memcached server or save in one instance and try to read from another15:17
portdirectit replicates but relys on a 'headless service'15:17
portdirectwhich doesnt allow reconfig/scaling etc after a pod that consumes it has started15:18
dulekAlso a funny thing is that Kolla has single replica hardcoded: https://github.com/openstack/kolla-kubernetes/blob/master/helm/microservice/memcached-deployment/templates/memcached-deployment.yaml#L3315:18
xekmemcached itself doesn't replicate key-values15:19
portdirectxek: I'd be happy to approve this, but obviously would want consensus15:19
srwilkers+115:20
srwilkersyeah, this blueprint is great.  id also approve moving forward with this approach15:22
lrensingi'm good with you taking it on xek15:23
portdirectso we have consensus?15:23
lrensingi look forward to seeing memcached move forward :)15:23
lrensingyes from me15:23
portdirectnice one xek :) memcached has been a thorn in my oslo side too long :D15:24
srwilkersany other comments or concerns here?15:25
srwilkers#topic PTG planning15:26
*** openstack changes topic to "PTG planning (Meeting topic: openstack-helm)"15:26
srwilkersso the PTG is less than two months away, and i think it'd be a good idea to start drafting up the items we'd like to target for those who will be present that week15:27
srwilkerssince we're a hosted project, we won't be allocated reserved space and we won't be included on the schedule15:27
srwilkersbut i've been told we're free to use the common spaces to meet, and we're responsible for advertising where we'll be hanging out while we're there15:28
*** krtaylor has joined #openstack-meeting-515:28
* portdirect votes for by the pool15:28
srwilkershere's an etherpad we can use to add ideas/topics to between now and then:  https://etherpad.openstack.org/p/openstack-helm-denver-ptg-topics15:29
*** nkp349 has joined #openstack-meeting-515:29
srwilkersand i'll make sure to bring it up each weekly meeting as a friendly reminder15:29
lrensingthat'll be good srwilkers15:30
srwilkersreally looking forward to seeing some of you there :)15:30
srwilkersbut that's all i have wrt the PTG15:32
srwilkerssince we're out of topics, we've got ~30 minutes for any open discussion items15:32
srwilkers#topic open discussion15:32
*** openstack changes topic to "open discussion (Meeting topic: openstack-helm)"15:32
lrensingi'll kick this one off since it's been a topic in irc this morning-15:32
lrensingthe ceph chart has been going through a few changes this week and some community members have had some issues getting it redeployed15:33
raymaikao/15:33
lrensingi believe current master is stable again, but if anyone finds any issues with it, bring it up in IRC so we can discuss, and if not much comes from that discussion please file a bug in launchpad so we can address it there15:34
portdirectI've got 2 labs running from master (deployed in last 18 hours)15:35
portdirectboth seem stable - though I would not be surprised if there a few gremlins in there - dependant on network config15:35
lrensing++15:36
portdirectits worth noting that we use ceph for all gate jobs - so it is tested for both pvc, and glance over 140 times a day :D15:36
lrensingalso, configuring ceph to use disks instead of directories is coming soon15:36
portdirectbut thats on the same hw config....15:36
lrensingbut anyways - thats all i had on that15:37
raymaikayeah, I'm trying to find the root cause of my problem. I'll let you know if I manage to fix it or find something that points to a more specific problem than the logs I posted this morning.15:40
dulekAs the discussion died a bit - I've rebased Keystone fernet tokens patch again if anyone is interested: https://review.openstack.org/#/c/463730/15:42
srwilkersawesome dulek.  we'll have a look at that today for sure15:44
portdirectdulek: I 'm gonna enable cronjobs in the k8s api, and update docs accordingly today15:45
dulekportdirect: That would be awesome.15:45
portdirectat that point I'd really like to make this the default and merge15:45
portdirectthanks for all your work on this dude :D15:45
srwilkersagreed.  looking forward to getting it to the finish line15:46
dulek:)15:46
srwilkersany other topics?15:47
lrensingnone from me - given the long pause i think we can wrap this one up a little early15:48
srwilkersalright.  ill go ahead and end the meeting.  thanks everyone :)15:49
