dmelladoapuimedo: ltomasbo irenab09:34
dmelladoI'm about to burst in tears of happiness09:35
dmelladojenkins finally gave me a +109:35
dmelladoon my patch09:35
dmelladohttps://review.openstack.org/45929209:35
dmelladocould you please merge it so I can remove my gerrit ref on devstack? xD09:35
ltomasbodmellado, you can still get the -1 on the verification that's triggered after the +W09:38
ltomasboxD09:38
dmelladoltomasbo: if that happens, I swear I'll get to find where does the infra lab is located09:39
dmelladoand then they'll fear me09:39
ltomasbolol09:40
ivc_dmellado done :)09:46

mchiapperohi all10:34
mchiapperoI have a question10:34
mchiapperoregarding the nested use case in general10:34
mchiapperoin theory the master node could be outside the VM, right? However if this is true, what are the assumptions that we deem acceptable in terms of configuration?10:36
mchiapperothe first one could be that all the minions are running nested10:36
mchiapperowhat are the assumptions around the nested usecase?10:38
mchiapperoespecially for the VLAN approach, I guess VIDs are VM specific, right?10:41

ltomasbohi mchiappero11:43
ltomasbonot sure I completely got your question11:45
ltomasbodo you mean if you need a kubernetes cluster all baremetal or all nested?11:45
mchiapperosay you have two VMs and want to run a minion on each of them11:48
mchiapperoyou could have a single kubernetes master and, I would say (am I correct?) a single kuryr controller11:48
mchiapperokuryr should then keep that into account, I don't think it does at the moment11:49
mchiapperoso I was wondering what are the constraint there11:49

*** kzaitsev_ws has joined #openstack-kuryr11:51
ltomasbomchiappero, and the master is runing baremetal?11:57
ltomasboor in another VM?11:57
mchiapperoyes, that could be an option11:57
mchiapperouhm... I guess it doesn't make any difference... does it?11:58
ltomasboif it is running in another VM, and you just add 2 worker nodes to the kubernetes cluster11:58
ltomasbowhy the kuryr-controller needs to have anything different?11:58
ltomasboyou just need to have the kuryr-cni in those minions11:58
ltomasboand then, the kuryr-controller will make the proper calls to neutron-server, right?11:58
mchiapperokuryr-controlelr needs to know about the parent interfaces on those VMs11:59
mchiapperohow are VIDs handled?11:59
ltomasbomchiappero, yes, but we have the assumption is the one corresponding to the hostIP11:59
mchiapperoanyway meeting... but it's something that should be considered12:00
ltomasboupsss12:00
mchiapperook, but that is not the only thing I'm afraid12:00
ltomasboand regarding the generic/nested mix12:00
ltomasboI don't think that will work at the moment, as the kuryr-controller will only use one driver at a time12:01
ltomasboso, it will either create normal port or subports for all the minions12:01

ivc_dmellado so, you found that infra lab? XD13:35

dmelladoin any case I'm discussing on #openstack-infra13:35

ivc_funny thing is when you click on that failure, you get "File Not Found"13:36
ivc_they are cleaning up fast :)13:37
dmelladoit seems that it might be a netwrk failure that happens13:37
dmelladoonly in some infra cloud providers13:37
dmelladoso it's just sheer luck that it passes or not13:37

dmelladocould this just be because of OSIC?14:56

dmelladocan anyone enlighten me about if we do something different in our dsvm15:27
dmelladofor ipv6?15:27
dmelladohow do we treat ipv6?15:27
dmelladoAFAIU that should be transparent for us, isn't it?15:28
*** pcaruana has quit IRC15:28
dmelladonet.ipv6.conf.all.disable_ipv6 and net.ipv6.conf.default.disable_ipv615:29
dmelladodo we set these up? ^^15:29
mchiapperoltomasbo: thank you15:39
ltomasbomchiappero, your welcome!15:39
mchiapperochanging later would mean having to bump to 1.1?15:40
*** dougbtv__ has quit IRC15:40
mchiapperoif so, it's probably best to make a decision now15:40
*** kzaitsev_ws has quit IRC15:41
ltomasbomchiappero, also if the first option is selected for now?15:41
ltomasboI think we would need to bump to 1.1 if we use the second approach and then move to the third, right?15:41
ltomasbowe are already using the first approach (for nested-vlan), right?15:42
ltomasbomchiappero, I don't have any strong opinion though. IMO third option will give us more flexibility (and may be needed at some point) but I'm fine with the first two too15:43
ltomasboperhaps, a bit more in favor of the first one, but as I said, no strong opinion15:43
dmelladoltomasbo: mchiappero now that I see someone around15:46
dmelladoto you have any information on this?15:46
