openstackgerritNgo Quoc Cuong proposed openstack/fuxi master: Fix N529 Method's default argument should not be mutable  https://review.openstack.org/48202306:56
apuimedoirenab: pong07:04
irenabapuimedo, in case for the nested deployment in devstack, I see some issue with second VM deployment07:10
apuimedoirenab: what do you mean, second VM deployment?07:10
apuimedoyou mean two VMs for the K8s cluster?07:11
irenabI think the alsways the first ip in the range is chosen for the k8s api service07:11
irenabhttps://github.com/openstack/kuryr-kubernetes/blob/master/devstack/plugin.sh#L15007:11
irenabdeploying 2 VMs on same devstack  and then kuryr-k8s inside the VM07:11
irenabI guess it must be different tent to make it work07:12
irenabs/tent/tenant07:12
apuimedoirenab: or at least different networks07:13

longfei_zhang_apuimedo, for k8s cluster if there are many minion hosts we need to deploy the cni to each minion host, right?09:12
irenablongfei_zhang_, yes09:14
*** kiennt has joined #openstack-kuryr09:15
kzaitsev_wslongfei_zhang_: if you don't deploy a CNI on a minion node that node would not be marked as "NotReady" by k8s09:19
longfei_zhang_irenab, i asked one question at this channel some days earlier , if there more than one master host in k8s cluster , i deployed kuryr controller to each of them, and the kuryr controller only monitor the local host address and 80 port, why all the kuryr controllers try to request neutron resource when i try to create a pod ?  i still can not understand this case09:22
longfei_zhang_kzaitsev_ws, yes09:22
irenablongfei_zhang_, we currently (yet) do not support HA for controller node09:22
longfei_zhang_irenab, yes09:23
irenablongfei_zhang_, so for now please start with single master node09:24
longfei_zhang_irenab, my confusion is all the kuryr controller only monitor http://localhost:8080 address, i thought only one controller could get the  create pod event? the the fact is all these controller on different master host can get the create pod event09:30
longfei_zhang_irenab,all these controller on different master host can get the SAME create pod event09:30
irenablongfei_zhang_, with current kuryr-controller, we do  not support multiple instances09:31
longfei_zhang_irenab, ok09:32
irenaball k8s api wanchers will get events as requested09:32
irenabwatchers09:32
irenabthe problem is that for now, there is no mechanism in place which one of the controllers will handle the ecent09:32
longfei_zhang_irenab,yes09:33

kzaitsev_wslongfei_zhang_: I don't really understand your confusion. if you create a pod in a multi-master k8s should it matter which api to ask to get that pod status?10:19
kzaitsev_wsI believe this is exactly what multi-master case solves. you can ask any master's api and you would get identical responses10:20
kzaitsev_wsalso you might want to ask k8s developers why this happens =) we mostly develop kuryr things around here.10:21
kzaitsev_wshowever imo the behaviour is expected.10:21
longfei_zhang_kzaitsev_ws, if i monitor the k8s api lb address i could understand that i can get identical responses10:47
longfei_zhang_kzaitsev_ws, if i just monitor the master http://localhost:8080 address , i thought only one master need to take the request10:48
longfei_zhang_kzaitsev_ws, otherwise, these masters should create 3 same pods10:49
longfei_zhang_kzaitsev_ws, i need to check this with k8s developers10:50
kzaitsev_wsdoes it matter which master you ask for 'kubectl get pods'? =)10:52
kzaitsev_wsor rather should it matter?10:52
apuimedoit should not10:52
apuimedosame for watching10:52
apuimedothere's only one cluster10:52
apuimedolook at it this way10:52
apuimedothere's an etcd cluster where the three API servers can write10:53
apuimedobut the events propagate through all the API servers10:53
apuimedootherwise appications using the API would react inconsistently to events10:53
apuimedowhat you assumed would be to have three federated clusters, not a single one10:54
longfei_zhang_apuimedo, you told me a good advise "the best thing to do now is to put the kuryr controller in a replication controller of size 1"10:58
apuimedothanks10:58
longfei_zhang_apuimedo, thank you ,i will try it10:59

kzaitsev_wsnp. I probably forgot a couple of things and we should've assigned someone to put meeting minutes )14:06
