sbezverkwhat is interesting management connectivity is working fine00:03
kfox1111thtas pretty weird.00:03
kfox1111kubeproxy only tweaks iptables as far as I can tell.00:03
kfox1111using canal for sdn in the vm's?00:03
sbezverkkfox1111: that is what I think breaks things00:04
*** yangyapeng has quit IRC00:04
sbezverkit is probably allows management traffic as is but other interfaces blocks all unknonw to it00:04
kfox1111it shuld only be enableing vxlan tunnels. not sure why an arp would fail after that.00:04
kfox1111are you using keepalived too?00:04
sbezverkonly on management side00:04
*** goldyfruit has quit IRC00:05
kfox1111iptables/selinux/filrewalld disabled everywhere?00:05
sbezverkselinux and firewalld yes00:06
sbezverkI did not explicitely disabled iptables00:06
*** rwallner has joined #openstack-kolla00:06
kfox1111should only need to if you installed package iptables-service00:07
sbezverkit does not seem there is iptables service00:07

kfox1111https://review.openstack.org/#/c/408725/200:15
kfox1111seriously.... its like no one tests this stuff with real systems. :/00:15
jascott1overheard last night-> stranger: "At Oracle we used to go out for shots at lunch" me: "Hey that explains a lot about my database!"00:18
kfox1111hehe00:18
sdakejascott1 OH "When we merged patches into nova, we brought donuts into the office." :)00:18
jascott1haha yeah i have heard that one00:18
sdakei was pretty stunned tbh :)00:19
kfox1111I think 9 times out of 10 the upgrade issues I've hit were in nova or neutron.00:19
sdakekfox1111 you haven't even begun to feel the pain when going to ocata :)00:19
kfox1111sdake: I've had clouds I've upgraded constantly from havana, including a centos 6->7 upgrade.00:20
kfox1111felt the pain. :)00:20
sdakekfox1111 just wait until ocata ;)00:20
kfox1111heh.00:20
kfox1111we'll see if openstack makes it that long...00:21
sdakeopenstack here to stay00:21
sdakehate to break it to you naysayers :)00:21
kfox1111thats not exactly what I said.00:21
sdakeperhaps i misinterpeted00:21
*** rwellum has quit IRC00:21
kfox1111the openstacks in question stick around long enough to put the effort of upgrading to ocata.00:22
*** salv-orlando has quit IRC00:22
kfox1111rather then just getting rid of. time will tell. :/00:22
kfox1111it may be easier to shift workload to k8s and drop openstack for some clouds.00:23

jmccarthyDoes this workflow work https://docs.openstack.org/developer/kolla-ansible/quickstart.html ? After pip installing kolla-ansible 4.0.0, the next steps don't seem to work (like Copy the configuration files globals.yml and passwords.yml to /etc directory. #CentOS cp -r /usr/share/kolla-ansible/etc_examples/kolla /etc/kolla/)14:00
jmccarthyIs there a newer doc for 4.0.0 ansible type deploy 'Install Kolla for deployment' style (that doesn't involve building images) ?14:01
egonzalezjmccarthy, copy those files should work, what error is giving you?14:02

egonzalezubuntu or centos? are in different paths14:02

egonzalezjmccarthy, when was installed, atm kolla-ansible is 4.0.1 version14:08
jmccarthyStrange - just 5 minutes ago14:08
jmccarthyOk I must have something screwy in this system then14:08
jmccarthyDam ok I'll try it again :)14:08
egonzalezhrm, have you ever installed kolla-ansible from git repo?14:08
egonzalezjmccarthy, can you paste full pip freeze output?14:09
jmccarthyNot in this VM, it's only about 30 mintues old - but possibly I have forgotten something one my scripts does ..14:09
jmccarthyOk I think I will start over with fresh VM, if you got it ok, then must be something I screwed up lol14:11

sdakejascott1 you have already run helm install on nova-api19:38

kfox1111sdake: this one https://kubernetes.io/docs/admin/service-accounts-admin/19:38
kfox1111I think sbezverk's right. you can add more. but if the default one's broken, adding another one will probably just create another broken one.19:38
kfox1111kolla-kubernetes should provide support for overriding which service account will be used per package at some point though.19:39

ReepicheepSo I have been playing with Kolla-ansible for a couple weeks now.  it seems evedent that a lot of current development efforts are with kolla-kubernetes20:30
ReepicheepI would like to move forward into production.. Should I take a serious look at kolla-kubernetes now?20:31
*** chas has quit IRC20:31
ReepicheepI know the answer is probably "it depends" but what is the general feelling for the future if this is a long term deployment?20:32
jascott1Reepicheep there is no production worthy release yet but we are working on it20:33
jascott1if you want to get familiar now and help out you will be an expert by the time it gets there ;)20:33
ReepicheepI would love to do that.. I just need to provide a place in the mean time for my co-workers to start getting their hands wet with OpenStack20:34
kfox1111Reepicheep: I'd say it depends on your tolerence for building from scratch. if you are already building openstack clusters from scratch, kolla-kubernetes should be about on par with that for production readyness. If you want something turn key, its definitely not that yet.20:35

ReepicheepI have built them from scatch for a while.. I also then tried fuel for a while but then found it to opinionated / restrictive20:37
kfox1111yeah.20:39
sdakeReepicheep note - if you want something to ramp up your team on how openstack works - kolla-ansible is a great solution for that20:39
kfox1111I've built all mine from scratch too.20:39
kfox1111I do weird stuff like run vxlans over ip over ib.20:39
Reepicheepmost of the "Turn Key" solutions seem to price them selfs out of my K-12 budget quickly.  :|20:39
kfox1111fuel didn't want to support that... :)20:39
sdakeReepicheep its mature and flexible20:40
kfox1111had to make due with whatever hardware I had available at the time.20:40
Reepicheepso it's seems I can choose to commit to using kolla-ansible today which is some what of a long term commitment considering the expectation of an environment to stick around20:46
inc0aaaand I'm done, broke my node networking without hope of restoration:P reprovisioning OS and starting fresh20:47
Reepicheepor I could go with kolla-kubernetes which may be much more work now but possibly a better longturm direction as the product matures20:47

inc0k8s is cool, but not for everyone20:50
*** jtriley_ has quit IRC20:50
jascott1hmm still cant grok the problem with mariadb-0 crash20:50
kfox1111only time will tell where contributors will put the work.20:50
inc0yup20:50
jascott1kubectl describe and logs, and /var/logs/containers, nothing showing an error20:50
kfox1111jascott1: does doing a regular pod and execing in show anything odd?20:51
ReepicheepI do like k8s,  I drank the docker coolaid quite a while ago .. and k8s definatly seems to be the orchistration tool of choice for many20:51
inc0yeah20:51
jascott1kfox1111 think its a volume problem20:52
kfox1111jascott1: what driver are you using?20:52
inc0k8s is cool, I just think not everyone will want additional orch layer under their openstack20:52
kfox1111volume issues usually show up in the describe pod output.20:52
jascott1nothing in maria logs but seeing storage errors when grepping thru all logs20:52
inc0if you're moving towards k8s big time, that's cool thing to do20:52
kfox1111inc0: I disagree. there is always that extra layer. ansible or k8s.20:53
kfox1111no "extra"20:53
inc0well ansible is glorified ssh20:53
kfox1111its an orchestration layer via ssh. and doesn't run all the time. but its as black magicy as k8s. :)20:53
inc0while k8s is full fledged cloud orch engine20:53
kfox1111though I find k8s's black magic easier to grok.20:53
*** shasha___ has joined #openstack-kolla20:53
inc0well ansible has little of magic, it's a shellscript over ssh written in yaml20:54
inc0things happen in order on hosts you want them to happen20:55
inc0nothing more nothing less20:55
kfox1111its a complicated programming langage written in yaml.20:55
Reepicheepwell I have been using puppet for years so even using kolla-ansible my initial thoughts where,, really descriptive instead of declaritive .. hmm.. I guess it time for me to try this ansible stuff ;)20:55
inc0yeah, ansible is not declarative as puppet or k8s really20:56
Reepicheepso the jump to a for k8s orchistration running the openstack would not be much more of a jump20:56
inc0maybe that's the core of our disagreement;) I never really used declarative stuff20:56
kfox1111inc0: yeah.20:56
Reepicheepinc0: lol.. I know and I was / am still kinda in the other camp20:57
Reepicheepbut if it get's the job done.. all the better20:57
kfox1111its spin up time for understanding what the language does. imperitive can take a lot more time to bring up to speed. k8s's pod descritpion is a relatively small declarative language.20:57
inc0yeah I don't think one is better than other20:57
kfox1111yup.20:57
kfox1111ansible definitely has its uses. :)20:58
inc0but to do complex stuff you need to abuse it20:58
*** shasha___ has quit IRC20:58
kfox1111yeah. k8s isn't intended to do complicated workflows. something drives it for that.20:58
*** tvignaud has quit IRC20:58
inc0and that something is missing, can be ansible :P20:59
inc0I think that's reason I'm not big fan of k8s...you still need something to run it20:59
inc0and certain tasks becomes complex problems21:00
kfox1111thtas why I was insistent on k8s packages being seperable from orchestration system.21:00
Reepicheepyup.. I have always been preaching that there is no magic bullet when it comes to tools so it's probably going to be a combination of many21:00
kfox1111so if someone wants to drive k8s deployment of openstack with ansible, more power to you. :)21:00
inc0yeah21:00
inc0maybe good idea is to ansible install k8s, compute nodes and  stuff like that while k8s runs services21:01
inc0so here's thing, if I'd run my own k8s apps21:01
inc0I'll deploy them with ansible21:01

ReepicheepI would probably use terraform (descriptive) ;)21:02
*** spsurya has quit IRC21:03
kfox1111terraform's becoming very popular around here.21:03
inc0I don't know first thing about it21:04
Reepicheepfor deployment of k8s I have used two tools to simplify it .. murano (that would be odd in this instance) and rancher21:04
*** tvignaud has joined #openstack-kolla21:04
inc0maybe it's time to learn21:04
kfox1111inc0: kind of a conglomeration of ansible and heat.21:04
inc0which might be good21:04
inc0in fact, there are tasks better for declarative and tasks better for imperative21:05
kfox1111yeah.21:05
ReepicheepI will probably go the Rancher route because we are aleady invested in Rancher21:05
inc0maybe correct tool is one that will coherently support both models21:05
kfox1111Reepicheep: I havent played with it yet, but hav been keeping an eye on it. always looked kind of cool.21:05
kfox1111inc0: +121:06
Reepicheepso this is what I have got out of this.. It's Friday.. monday I'm going to deploy an instance of k8s to do kolla-kubernetes on .. may as well try21:07

inc0kfox1111: I don't see why not21:13
kfox1111inc0: been usign prometheus a lot. its very cool. :)21:14
inc0I mean we're getting lots of containers that aren't openstack21:14
inc0which is cool/bad21:14
inc0I think we need to figure out better way to handle incoming containers21:14
kfox1111I think we shoudl carry containers for stuff not maintained by the hub officially probably?21:14
kfox1111of there is an official container, then maybe we should consider using it.21:15
inc0well I don't want kolla to become poor mans dockerhub for unwanted images21:15
kfox1111+1. I'm only talking about wanted images. :)21:15
kfox1111hence the prometheus-openstack-exporter request. :)21:15

jascott1_yeah i destroyed whole setup, commented the maria install with helm and everything after, rebuilt, shelled in and edited the yaml and did helm install22:42
kfox1111inc0: imperitive at each step of the workflow, but the step itself is declarative.22:42
kfox1111jascott1_: how are you backing it? hostpath? ceph? other?22:43
jascott1_hostpath afaik22:43
kolla-slack<inc0> I think k8s job is sth like that22:43
