apuimedovikasc: this is the kubeadm blueprint https://blueprints.launchpad.net/kuryr-kubernetes/+spec/kubeadminstallable07:22
apuimedoirenab: I put you as approver. Please, go over it07:22
irenabapuimedo, ack07:23
vikascapuimedo, thanks. Can you please assign me this bp07:23
apuimedovikasc: not before it is approved by irenab :-)07:26
irenabapuimedo, checking now07:26
vikasccool :)07:26
irenabapuimedo, I have a question regarding Kuryr CNI as Daemon set07:27
irenabThis is required once we rework the CNI to have daemon part07:28
apuimedoirenab: go ahead07:28
irenabfor now its passive binary that runs as part of the kubelet07:28
apuimedoirenab: yes and no. You could always just tell people to have it run by systemd on each worker node07:28
apuimedoby daemonset makes it all the simpler07:28
apuimedofor now it's basically a way to place (via the volume mount) the kuryr executable somewhere that kubelet can see it07:29
irenabbut currently CNI is not service from the systemd perspective07:29
irenabwhat am I missing?07:29
apuimedoirenab: you are not missing anything07:30
apuimedoright now it will be a noop pod07:30
apuimedowell, not exactly, it will still run one container that installs the kuryr executable in the mounted path07:30
apuimedo/etc/cni/net.d07:31
apuimedoand so on07:31
apuimedoyou can see an example of the installation part at https://github.com/coreos/flannel/blob/master/Documentation/kube-flannel.yml07:31
irenabmakes sense. Do you mind I update the bp with these details?07:31
apuimedoirenab: do you remember which other blueprints I said I'd do yesterday?07:31
apuimedoirenab: right on it07:31
apuimedothanks07:31
irenabI think the other one was for the CNI split07:32
apuimedothanks irenab !07:34
apuimedoargh!!!!07:35
apuimedoI fucking hate launchpad07:35
apuimedoIt swallowed my update to the blueprint07:35
apuimedoI hate when work is lost that way07:35
irenabapuimedo, prefer Jira?07:35
apuimedoirenab: I prefer bugzilla07:36
irenabapuimedo, I approved the bp07:38
apuimedoirenab: ok. Check now07:40
apuimedoI added the things07:40
irenablooks good07:42
apuimedothanks irenab07:42
apuimedoI should do the blueprints for the CNI split and for the /health endpoints07:43
vikascirenab, apuimedo : i am starting to work on the daemonset bp07:43
apuimedovikasc: very well07:44
apuimedovikasc: it's a bit big, so let us know if you need help07:44
irenabvikasc,  maybe worth to draft short spec07:46
vikascapuimedo, sure, i will try to complete it iteratively.07:46
vikascirenab, how it would be if i do spec after a quick prototype07:46
vikasc?07:46
irenabsure, I do not think its possible otherwise :-)07:47
vikasccool, will try to complete prototype this week07:47
apuimedoirenab: vikasc: I'm not sure a spec is warranted07:50
apuimedoup to you guys07:50
apuimedothis blueprint in my mind is about a couple of small patches to kuryr-k8s and mostly contrib/kubeadm yaml addition07:51
*** egonzalez has joined #openstack-kuryr07:51
irenabI guess it will be based on the finding vikasc hae once prototyping07:51

irenabapuimedo, about this bp https://blueprints.launchpad.net/kuryr-kubernetes/+spec/driver-handler-opt-loading08:07
apuimedowe should already have it in08:08
apuimedomaybe you can rescue your patch08:08
irenabcan you check the patch and let me know what do you think? If direction is fine, I can check other places where split is applicable08:08
irenabsure, I can rebase it and respin08:09

apuimedohow is it different from multus, irenab ?10:34
irenabapuimedo, I do not know yet, need to check the details10:34
apuimedoirenab: cool10:34
irenabcatching up on k8s multiple networks10:34
vikascseems for now its decided that TPR+annotations will be used10:38
vikascand no api changes to include network objects10:38
vikascthere is so much discussion going on for multi-networks but i wonder why nobody has suggested to use scheduler-extender10:44
apuimedogood10:50
apuimedovikasc: I did suggest it10:50
apuimedoand they sent me to hell :P10:50

*** janki has quit IRC11:08
vikascirenab, some people had doubts about if it is really required11:09
irenabyes, the general approach in k8s is to have very app facing API, so minimal net/ip details11:10

vikasci have 1.6.1, all-in-one.12:00
apuimedonot all in one12:01
apuimedoI have 1.6.212:01
vikascwhen i try to launch kuryr-controller pod, it fails to schedule because of this taint on the node object: Taints:node-role.kubernetes.io/master:NoSchedule12:01
apuimedowith one master and two nodes12:01
apuimedovikasc: how did you deploy? with kubeadm?12:01
vikascyes12:01
apuimedotowards the end of the guide it says to remove the noschedule12:02
apuimedodid you maybe forget to do that?12:02

vikascapuimedo, yes :)12:02
vikascapuimedo, thanks!12:02

irenabapuimedo: shall we bump hyperkube version?13:04
