| ltomasbo | morning! | 07:27 |
| apuimedo | ltomasbo: how's your env? | 07:27 |
| ltomasbo | apuimedo, the openshift one? | 07:28 |
| *** aojea has joined #openstack-kuryr | 07:29 | |

| *** aojea_ has joined #openstack-kuryr | 07:30 | |
| ltomasbo | working (I suppose) | 07:30 |
| ltomasbo | I was going to try some modification of the port pool there (for the baremetal) later today (if time allows) | 07:31 |
| apuimedo | ltomasbo: did you notice that all the service patches are in master? | 07:32 |
| ltomasbo | yes, I saw that this morning | 07:33 |
| ltomasbo | but I was already using those | 07:33 |
| ltomasbo | now I just need to pull the master then, instead of ivc- patch | 07:33 |
| ltomasbo | great! | 07:33 |

| ltomasbo | apuimedo, so, kuryr-kubernetes branch is going to be cut/tag now-ish? | 07:34 |
| apuimedo | yes. I will check if we are missing anything | 07:34 |
| apuimedo | and then cut | 07:34 |
| ltomasbo | apuimedo, great | 07:35 |
| irenab | apuimedo, there was good presentation by VMware guys at CNCF Berlin conference on k8s scheduling, will find and share the link | 07:35 |
| ltomasbo | and nice post, it could be really useful the scheduling... | 07:35 |
| ltomasbo | I'll take a look asap | 07:35 |
| ltomasbo | irenab, that would be great! thanks! | 07:35 |
| apuimedo | irenab: I saw. From salvatore, right? | 07:37 |
| apuimedo | sched.net | 07:37 |
| apuimedo | or something like that | 07:37 |
| irenab | yes | 07:37 |

| irenab | finally :-) | 07:38 |
| *** egonzalez has joined #openstack-kuryr | 07:38 | |
| apuimedo | we're back in full force then | 07:38 |
| ltomasbo | finally!!!??? xD | 07:38 |
| apuimedo | let's see if we can cut a release | 07:39 |
| apuimedo | irenab: can you review https://review.openstack.org/#/c/454294/ ? | 07:39 |
| irenab | apuimedo, sure | 07:40 |
| janonymous | apuimedo, irenab: yeah ovn one was good | 07:40 |
| irenab | janonymous, do you have the link? | 07:40 |
| irenab | apuimedo, the presentation on KubeVirt was very interesting too | 07:42 |
| apuimedo | was it Fabian Deutsch? | 07:42 |
| irenab | ltomasbo, apuimedo dmellado : https://www.youtube.com/watch?v=WWJ7AeEiaqc&list=PLj6h78yzYM2PAavlbv0iZkod4IVh_iGqV&index=50 | 07:43 |
| irenab | apuimedo, Itamar with someone else | 07:43 |
| dmellado | irenab: nice! thanks for the link! | 07:43 |
| apuimedo | ah, very well | 07:43 |
| irenab | apuimedo, for making K8s orchestrate both VMs and Containers | 07:44 |
| apuimedo | yes. I'm vaguely aware of the project. | 07:44 |
| apuimedo | don't know about details though | 07:44 |
| apuimedo | I'll probably have to watch the presentation | 07:44 |
| apuimedo | it does sound interesting | 07:44 |

| kzaitsev_ws | ivc: how would you connect to kubernetes service from pods, using kuryr-k8s with services? | 11:56 |
| apuimedo | kzaitsev_ws: just use the cluster ip | 11:59 |
| apuimedo | or you meant a host networking one? | 12:00 |
| kzaitsev_ws | well for kubernetes service (I mean access to k8s api) | 12:03 |
| kzaitsev_ws | kuryr-k8s would not work, as it expects service to have pods | 12:04 |

| apuimedo | kzaitsev_ws: for openshift integration we create members for the k8s service | 14:08 |
| apuimedo | the current patch creates everything except the members | 14:08 |
| apuimedo | as they are not on the pod network | 14:08 |
| *** pcaruana has joined #openstack-kuryr | 14:10 | |
| ltomasbo | apuimedo, kzaitsev_ws: the members of the router | 14:29 |
| ltomasbo | the ones for the other services work (I think) | 14:29 |
| apuimedo | ltomasbo: he's running plain k8s. So he only needs the members of the API services afaik | 14:30 |

| kzaitsev_ws | yeah, I'm running plain k8s. and I think I know what's wrong with my setup... | 15:27 |
| ltomasbo | kzaitsev_ws, that is a good starting point! | 15:28 |
| ltomasbo | xD | 15:28 |
| kzaitsev_ws | when creating k8s-service-network I've set a gateway, since we need it to be routable in case of kuryr-k8s right | 15:29 |
| *** tonanhngo has joined #openstack-kuryr | 15:29 | |
| kzaitsev_ws | for kube-proxy it's not required, since it works with iptables | 15:29 |
| kzaitsev_ws | but the catch is | 15:29 |
| kzaitsev_ws | k8s service, the one that handles access to k8s api itself | 15:30 |
| kzaitsev_ws | it took the ip of the default gateway =) | 15:30 |

| openstackgerrit | Hongbin Lu proposed openstack/fuxi master: [WIP] Make volume providers configurable in devstack https://review.openstack.org/457694 | 15:31 |
| kzaitsev_ws | am I correct that I should not have kube-proxy running at all? (I've disabled it with a NodeSelector =)) | 15:34 |
| kzaitsev_ws | I remember apuimedo mentioning it ) | 15:34 |
| kzaitsev_ws | idk. is there a way to change ip of a kubernetes service? =) | 15:36 |
| *** alraddarla_ has joined #openstack-kuryr | 15:37 | |
| apuimedo | you should not have it at all | 15:38 |
| apuimedo | it is known to make things blow up | 15:38 |
| apuimedo | there is no way | 15:38 |
| apuimedo | kzaitsev_ws: why do you want to change it? | 15:38 |
| kzaitsev_ws | well, my kubernetes-api service took the gateway ip address for the service-subnet )) | 15:39 |
| apuimedo | kzaitsev_ws: oh, yeah. That happens | 15:39 |
| openstackgerrit | Hongbin Lu proposed openstack/kuryr-libnetwork master: Avoid running more than one etcd process https://review.openstack.org/457361 | 15:40 |
| kzaitsev_ws | apuimedo: how do you workaround it? =) | 15:40 |
| apuimedo | we usually define the router ip to be the last one in the service subnet for this reason | 15:40 |
| kzaitsev_ws | use a smaller netmask for service net? | 15:40 |
| apuimedo | so, when we add the router interface to the subnet, we just tell it to use a neutron port we create manually | 15:40 |
| apuimedo | It's a bit crappy that we didn't find a way to tell the k8s service to just use a range | 15:41 |
| kzaitsev_ws | yeah, seems it impossible to exclude ips from service subnet in k8s =( | 15:41 |
| *** pcaruana has quit IRC | 15:41 | |
| openstackgerrit | Hongbin Lu proposed openstack/fuxi master: Avoid running more than one etcd process https://review.openstack.org/457363 | 15:41 |
| kzaitsev_ws | they just don't care, since they don't want the network to be routable anyway | 15:44 |
| kzaitsev_ws | yeah | 15:44 |
| kzaitsev_ws | seems the only option I have is to recreate the network | 15:44 |
| apuimedo | so, if you use my workaround, remember to put it as gateway for the pod subnet as well | 15:44 |
| apuimedo | (the new router iface ip) | 15:45 |
| kzaitsev_ws | hm, but that shouldn't be a problem for the pod network, right? | 15:46 |
| *** salv-orl_ has joined #openstack-kuryr | 15:49 | |
| apuimedo | sorry, I meant for the service subnet | 15:51 |
| apuimedo | as in, not to have the service subnet gateway pointing to .1 when the router iface is on 254 | 15:51 |
| apuimedo | for example | 15:51 |
| *** salv-orlando has quit IRC | 15:51 | |
| kzaitsev_ws | yeah, sure =) | 15:52 |
| kzaitsev_ws | btw. I've hacked kuryr-k8s a bit to make it create lbaasv2 lb's for kubernetes api service | 15:53 |
| kzaitsev_ws | I had to add it's network as an external network, so I'm not sure if this is a good idea | 15:54 |
| kzaitsev_ws | but I intend to have accessibility to k8s-api from pods =) at least try to have it | 15:54 |
| *** aojea has joined #openstack-kuryr | 15:59 | |
| apuimedo | for openshift, since it creates a k8s service, it works out of the box, only the members are missing | 16:01 |
| apuimedo | but for plain k8s, where there is no k8s service, some hackiness is needed, I suppose | 16:01 |
| kzaitsev_ws | apuimedo: members — you mean neutron lbaas members, right? | 16:04 |

| ivc | apuimedo, kzaitsev_ws: regarding the gateway ip, there's a TODO in our devstack https://github.com/openstack/kuryr-kubernetes/blob/master/devstack/plugin.sh#L156 | 16:47 |
| apuimedo | ivc: that's a funny way of cheating :-) | 16:48 |
| ivc | apuimedo yup | 16:48 |
| ivc | apuimedo but thats the only way you can 'exclude' ips from k8s ipam i think | 16:49 |
| apuimedo | I heard about some other way. But I don't remember the details and I didn't verify it's truth | 16:49 |
| ivc | apuimedo its still a workaround, but that would solve this annoying problem that pretty much everyone who tries kuryr without devstack asks about | 16:52 |
| apuimedo | right | 16:52 |
| apuimedo | can confirm everyone stumbles on this | 16:53 |
| ivc | maybe we could even make it part of kuryr controller (to create that service or crash right away with a meaningful error) | 16:54 |
| apuimedo | ivc: crashing seems best | 16:55 |
| apuimedo | it should detect if the service subnet is properly set | 16:55 |
| ivc | apuimedo by 'or' i mean "|" :) i.e. "create_service() if validate() else crash()" | 16:58 |
| apuimedo | sounds good | 16:59 |
| ivc | apuimedo it does not cuz its ugly :) but its better than answering the same question thousands of times - let kuryr do that for us XD | 17:05 |
