vikascdevvesa, hey morning :)07:44
vikascdevvesa, i found a bug in raven07:44
*** irenab has quit IRC07:44
*** irenab_ is now known as irenab07:44
vikascdevvesa, responsible for yesterday's  'unbound' problem07:45
vikascdevvesa, https://github.com/midonet/kuryr/blob/k8s/kuryr/raven/watchers.py#L462  here this 'binding:host_id':  should also be set07:48
irenabvikasc: it is not possible at this point07:48
vikascirenab, i understand limitation07:48
irenabracven does not know the host _id07:48
vikascirenab, scheduler will determine host07:49
vikascirenab, but if we dont pass it "binding:vif_type" is coming as 'unbound' from neutron07:49
irenabI am not sure one can enforce if raven runs before or ater the scheduler07:49
vikascirenab, and same is passed to cni driver07:50
irenabvikasc:  will be back to you later, in the meeting07:50
vikascirenab, and there it is not able to pick binding executable07:50
vikascirenab, sure07:50
vikascirenab, cant we wait in watcher and keep querying pod until node info is not available?08:03
vikascirenab, i mean querying pod info from api server08:04
irenabI wonder how it works for us  now …08:05
irenabvikasc: : jut for ‘hacking’ option, if you refer some arbitrary host, does it work?08:06
vikascirenab, i set it to same master node only for haking purpose.. after that getting this error on driver08:07
vikascE0817 13:11:25.784556   25673 pod_workers.go:138] Error syncing pod f803828f-644d-11e6-94a6-08002778068c, skipping: failed to "SetupNetwork" for "alpha.nginx_default" with SetupNetworkError: "Failed to setup network for pod \"08:08
vikascirenab,  still debugging08:08
irenabI would expect it to fail on ovs agent08:08
vikascirenab,  i have one node only.. i will also try hard coding this node08:08
irenabany neurron l2 agent errors?08:10
vikascirenab, thats what i am looking at .. could not find so far08:10
irenabthen I am not sure its binding problem, at least not neutorn08:11
vikascirenab,  now that from raven port info is coming with correct binding type.. will debug on driver side where exactly its failing08:12

devvesavikasc: pong12:39
devvesa(sorry, late)12:39
vikascdevvesa, hi12:39
vikascdevvesa, no worries :)12:40
devvesa:) what's up?12:40
vikascdevvesa, how do you guys debug driver :)12:40
devvesaI use remote-pdb12:40
vikascdevvesa, thanks for the pointer, will google about it12:40
devvesakind of "from remote_pdb import RemotePdb; RemotePdb('127.0.0.1', 4444).set_trace()"12:41
devvesaThen process waits untils a tcp connection at port 444412:41
vikascdevvesa, so found reason for yesterdays issue.. while creating a port raven should set host also12:41
devvesayou can connect to it using telnet: "telnet foo-host 4444"12:41
devvesawhat's the issue?12:42
vikascdevvesa, if 'binding:host_id' is not sent to neutron in port creation request it sets vif_type as unbound12:42
vikascdevvesa, and then in driver it fails to pick correct executable using 'unbound'12:43
vikascdevvesa, to workaround this , i am harcoding my node hostname for now12:43
devvesaUhm, and that's a Raven issue? Never experienced it... I wonder why12:43
devvesamaybe irenab knows12:43
*** pablochacin has joined #openstack-kuryr12:44
vikascdevvesa, I talked to her12:44
devvesaWhat she says?12:44
vikascdevvesa, she says its not possible at the moment to set host id12:44
irenabdevvesa: I think its becouse we use it with MidoNet plugin, Our port binding is different12:45
vikascdevvesa, because raven cant be guaranteed to run after schedular has figured out host12:45
vikascdevvesa, yes12:45
devvesaOh, that means MidoNet plugin does not consume this attribute12:45
irenabfor ML2 ihost_id t is needed to bind the port12:45
devvesaunderstood12:45
devvesaSo I suggest you to force it by now, next week I'll start the patch submitting12:46
devvesa(i will be on PTO till Tuesday)12:46
devvesaAnd see if we can fix it upstream soon12:46
vikascdevvesa, thanks for pdb help12:46
vikascdevvesa, i still not able to launch pod12:46
devvesaWhat I suggest make sense to you?12:46
irenabvikasc: fornow, please just hack, we should figure out if some sort of wait till k8sscheduler populates the node info is possible12:47
irenabin the raven watcher12:47
vikascirenab, i was also thinking on same lines12:47
irenabdevvesa: do you think we can change raven naming while restructure the code?12:47
vikascdevvesa, yes, makes sense tome12:48
vikasc*to me12:48
devvesairenab: Yes. What do you suggest12:48
devvesaI am very bad ad namings.12:48
irenabdevvesa: I am terrible with names12:48
devvesakuryr-k8s?12:48
devvesait is just the service name at all12:48
irenabkuryr-k8s-controller?12:49
irenabkuryr-k8s-watcher12:49
devvesaIt is ok to me as long as we don't have to answer again "what's Raven?"12:49
irenabjust something more self explanatory12:49
devvesaI have to be AFK next hour. See you later!12:50
devvesavikasc: any doubt, ask irenab :)12:50
*** devvesa has quit IRC12:50
vikascirenab, anything appended with 'watcher' should be fine :)12:50
irenabvikasc: agree12:52
irenabvikasc: I will try to look into this scheduler/raven dependency. Really do not want us to add CNI to call neutron to set the host12:53
apuimedoI propose 'oko'12:54

apuimedoHenryG: We were discussing the other day about our kuryr->kuryr-lib dependency15:52
apuimedoand I wanted to ask your take, since you have a similar situation in neutron with neutron->neutron-lib15:53
apuimedoI saw that you keep neutron master pinned to a specific neutron-lib release15:55
apuimedoso if a new neutron change required additions to neutron-lib15:55
apuimedothe timeline would be15:55
apuimedosend patch to neutron-lib15:55
apuimedorequest a new release15:55
apuimedoand in the patch to neutron, update the requirements line15:55
apuimedoHenryG: isn't that a very long process for those cases?15:56
apuimedoI suspect that neutron-lib is so mature and feature full that changes there are not that common15:56
