flwang1hmm... maybe strigazi is busy for something else17:19
flwang1let's cancel it?17:19
imdigitaljimyeah that would probably seem appropriate17:21
imdigitaljimunless we want to discuss a few things :P17:21
imdigitaljimive been watching your https://review.openstack.org/#/c/579043/ and https://review.openstack.org/#/c/578531/17:22
flwang1for https://review.openstack.org/#/c/579043/ , we need a patch in heat17:22
flwang1https://review.openstack.org/57948517:23
flwang1the good thing is that one has been merged17:23
imdigitaljimalso do we need to do any heat template version upgrades soon?17:23
*** serlex has joined #openstack-containers17:23
flwang1now i'm trying to cherrypick it to queens17:23
imdigitaljimoh good17:23
flwang1if you guys need it in pike, then do it17:23
imdigitaljimwe're using a version of latest17:24
imdigitaljimbut with our patches in it that havent been merged17:24
flwang1imdigitaljim: seems no template version upgrade needed17:24
imdigitaljimi just mean for other things17:24
flwang1just the server and agent communication issue17:24
imdigitaljimid like to have this one get merged soon17:24
imdigitaljimhttps://review.openstack.org/#/c/577570/17:24
imdigitaljimas well as this one17:24
imdigitaljimhttps://review.openstack.org/#/dashboard/self17:24
imdigitaljimalso i noticed in our kubernetes configuration we dont seem to create a proper kubeconfig file17:25
imdigitaljimor am i missing it?17:25
imdigitaljimfor remote cluster access17:25
flwang1https://review.openstack.org/#/c/577570/ is on my list, but i haven't done it, i was in very sick in last 4 days :(17:25
imdigitaljimoh im sorry! i hope you feel better :|17:25
flwang1just cold and  high fever17:26
flwang1now i feel better otherwise i can't join ;)17:26
imdigitaljimugh thats makes quality of life go down for sure17:26
flwang1thanks17:26
imdigitaljimbut do you know about that previous comment?17:27
imdigitaljimkubeconfig? do we generate it somewhere that im unaware of/17:27
flwang1i think it's under /etc/kubernetes17:27
imdigitaljimyeah theres nothing there that would properly do it17:28
imdigitaljimi didnt suspect it was, just wondering otherwise. i'll probably also have a PR for that17:28
imdigitaljimhttps://github.com/kelseyhightower/kubernetes-the-hard-way/blob/master/docs/10-configuring-kubectl.md17:28
imdigitaljimits like this for example17:29
imdigitaljimalso on the note of https://review.openstack.org/#/c/578945/: ill probably submit this broken down into smaller sequential patches17:30
imdigitaljimfor easier PR digestion17:30
flwang1sorry, i'm a little bit confused, maybe my brain  is still burning, if you want to access the cluster with a kube-config, can't you just call eval $(openstack coe config xxxx)?17:30
flwang1is that you're talking about?17:30
imdigitaljimlet me see if that works, i havent used that approach yet17:30
imdigitaljimsounds right though17:31
imdigitaljimas far as what im looking for17:31
flwang1depends on the user you're talking about17:31
flwang1if you're the user of the cluster17:31
flwang1then you should be able to get a kube-config like that17:31
imdigitaljimperfect17:32
imdigitaljimi believe thats the part im looking for! :) ill report back shortly17:32
imdigitaljimother than those few mentions, that's all i was going to talk about in the meeting as well17:32
imdigitaljimpush a couple PRs, some upcoming PRs, and some questions =)17:33
*** lpetrut_ has joined #openstack-containers17:33
flwang1https://review.openstack.org/#/c/578945/ that's a big change, better to split it into small patches17:33
imdigitaljimyeah definitely will be17:33
flwang1because we don't have good e2e testing now17:33
flwang1good good17:34
imdigitaljimprobably just linting-type stuff at first17:34
flwang1questions are always good17:34
flwang1imdigitaljim: btw https://review.openstack.org/58031417:34
imdigitaljimi saw that17:34
flwang1it's reverted though i don't think it's correct17:34
flwang1we should fix it instead of reverting it IMHO17:35
imdigitaljimyeah17:35
imdigitaljim100% agree17:35
flwang1otherwise, we have to take more effort to get it in17:35
imdigitaljimit looked like a trivial change too17:35
imdigitaljimas far as the fix17:35
imdigitaljimwell put that PR up again and i'll +1 it again17:36
imdigitaljimim still not clear from his first comment what was missing17:36
flwang1yep, i have to, i'm sorry i missed that line17:37
flwang1line 515 and line 521 https://review.openstack.org/#/c/562454/3/magnum/drivers/k8s_fedora_atomic_v1/templates/kubemaster.yaml17:39
imdigitaljimoh17:39
imdigitaljimwrite_flannel_config17:39
flwang1anyway, bad thing is seeing you patch being reverted :D17:39
flwang1yes17:39
imdigitaljimyeah17:40
imdigitaljimi believe that it should move forward in this scenario with a simple bug fix17:40
imdigitaljimanyways /shrug17:40
flwang1true, i will ask a beer from strigazi to make me happier17:40
flwang1or another CERN helm17:41
*** lpetrut_ has quit IRC17:41
flwang1strigazi: ^17:41
imdigitaljimoh snap!17:41
imdigitaljimgiving out CERN helms?!!17:41
imdigitaljimrevert a couple of mine then =]17:41
flwang1imdigitaljim: haha17:41
flwang1the background is he has said he will give me a cern helm if i join berlin summit17:42
flwang1but im not sure yet due to the budget17:42
imdigitaljimsure i bet thats a pricey trip from NZ17:43
flwang1it's a very long trip17:43
flwang1last time to paris, take me about 40 hours17:44
*** jmlowe has joined #openstack-containers17:44
flwang1to barcelona took me about 37-40 hours17:44
flwang1so i'm not very keen to berlin TBH17:44
imdigitaljimoh geez17:44
imdigitaljimyeah and i bet you're super jet lagged17:45
flwang1exactly17:45
flwang1so i really enjoy the summit at Sydney :D17:45
flwang1btw, just curious, except magnum, and senlin, do you use any other openstack upper layer services?17:47
flwang1like trove, zaqar, manilia?17:47
imdigitaljimzaqar17:48
canori01I use manila17:49
*** lpetrut_ has joined #openstack-containers17:52
flwang1you're using zaqar??17:54
flwang1how do you use it? by senlin for notifying?17:54
flwang1i was the zaqar ptl for several cycles, we're always seeking some real user cases17:56
*** serlex has quit IRC17:59
imdigitaljimim not working on that component but yeah i believe just with senlin18:01
imdigitaljimits not in heavy use or anything iirc18:01

imdigitaljimso i have a solution that could be used19:02
imdigitaljimbut its an odd solution19:02
imdigitaljimflwang1: did you have something in mind already?19:02
imdigitaljimor was this change ready to go?19:03
imdigitaljimit looks appropriate afaik19:04
*** kbyrne has joined #openstack-containers19:05
flwang1i think it's ready to go19:18
flwang1and after using it, i never see the etcd timeout19:19
flwang1but will see19:19
flwang1technically, i think if k8s thinks etcd is ok, then we just need to trust k8s19:19

markguzHi. trying to debug why my magnum installation is failing to create a cluster.  currently running ocata and using fedora-atomic-ocata image.22:41
*** armaan has quit IRC22:41
markguzetcd always fails to start on the kubemaster with the error open /srv/kubernetes/server.crt: no such file or directory22:41
markguznetwork is working can reach the floating ip and ssh into the kubemaster.  Where is /srv/kubernetes/server.crt: created? can't seem to find that point of failure22:42
markguznvm I finally figured it out. found the failing part.22:48
*** hongbin has quit IRC22:50
*** dardelean has joined #openstack-containers22:57
*** rcernin has quit IRC22:58
flwangmarkguz: any reason why you have to use ocata magnum?23:01
*** rcernin has joined #openstack-containers23:01
*** ianychoi_ has joined #openstack-containers23:01
flwangwe know a lot of bug fixes not backport to ocata23:01
flwangmarkguz: i would high recommend using stable/queens for both magnum and heat23:01

markguzflwang: because in the real world folks can't just be upgrading their entire stack every 6 months23:16
markguzflwang: it would be nice to do that, but ocata is barely a year old and folks tell me... that's so old we can't help you anymore23:17
markguzflwang: anyway i've narrowed down the problem to the magnum_domain_admin getting this error You are not authorized to perform the requested action: identity:create_user23:18
markguzthe user has the correct role assigned for the magnum domain23:18
flwangmarkguz: you don't have upgrade your entire stacks23:19
flwangand i'm in the real world too :)23:19
markguzflwang: nice for you. i have a limited set of resources and limited ability to play around with stuff. so i have ocata installed at the moment and am using ocata versions.23:20
markguzflwang: are you saying ocata is fundamentally broken and I am wasting my time?23:21
flwangI'm just kindly recommending and it's your call23:21
flwangi'm not saying it's foundamentally broken, because I never test it. but based on my experience on Pike, it's not good.23:21
flwanglet me show you something23:21
flwangare you try to deploy k8s or other coe?23:22
markguzflwang: you don't have to convince me of the benefits of always running the latest code. I just don't have the time and resource to keep up to date at the speed openstack dev cycle moves23:22
markguzi figured by getting onto ocata at least it would stop that, "your version is to old" bs23:23
markguzflwang: k8s23:23
markguzas far as i can tell the certificates are not being created because the magnum_domain_admin can't seem to create the cluster credentials23:24
flwangmarkguz: ok23:24
flwangi'm not trying to convince anybody23:24
markguzflwang: sorry. just tired of getting told to upgrade as a solution to every problem.  I know this is all free and i shouldn't complain but sometimes I just want to get something working.23:25
flwangmarkguz: i has been working on openstack for more than 6 years and i know your pain for sure23:26
markguzflwang: i;ve been using it , and trying to promote adoption here, since juno23:27
flwangthe community can give some help for old version issues, but sometimes it's just not in time. when I say show you something, i  just want to let you know if there is any critical issues you may run into later and then you can at least do a private cherry-picking23:28
flwanggood good23:28
flwangso we are one team but don't know each other23:28
flwangand except magnum, you may also need to keep an eye on heat23:30
flwangfor example, there is a multi region bug in heat now which i'm fixing23:30
flwangto continue on ocata, i would suggest setup a devstack env, comparing the conf of magnum and heat23:31
markguzflwang: the heat aspect is fine AFAICS. the stack is creating. what seems to be the problem is the trustee_admin isn't able to create the cluster admin id23:31
flwangthen if there is any issue, check the working flow and comparing the code23:31
flwangthen you need to check your heat.conf23:32
markguzflwang: the heat conf ? but it's the magnum_domain_admin that is failing to create the cluster users?23:32
markguzi tried running the test script in the troubleshooting section of the magnum docs23:33
flwangsorry, i mean check both, for heat see http://paste.openstack.org/show/725165/23:33
flwangfor magnum, check http://paste.openstack.org/show/725166/23:34
markguzflwang: yeah i have that much working. This is a fully working openstack deployment (except for magnum). been using heat for years in this stack23:34
flwangnice23:34
flwangi'm happy to help, just post your questions here23:35
flwangi'm in NZ, so probably online for the next 5 -6 hours23:35
markguzflwang: yeah i feel like it's a magnum config problem just trying to narrow it down. is "cluster_user_trust" an ocata config option for magnum?23:36
markguzi didn't see that in the docs23:36
flwangIt is23:37
flwangi'm going for lunch now, ttyl23:38
