kmadacHello, I'm trying to install kuryr to VM where I have single node k8s cluster deployed with kubeadm (nested deployment). I'm trying to do manual installation, but I do not know what networking type to choose. In kubeadm documentation there is information that it is a must to choose networking type (flannel, weave, calico...), but I thought that it15:50
kmadacshould be replace by kuryr itself. Unfortunatelly without choosing the networking type coredns pods are pending. I'm probably missing something. Do you guys have any hint?15:50

dulekkmadac: Hm, not sure about kubeadm, I never tried it with Kuryr.15:57
dulekkmadac: But for your Friday questions - this error was about Kuryr's service account not having enough privileges.15:57
dulekkmadac: If you want to install Kuryr, it should rather run in pods, not on VM's.15:58
kmadac@dulek: I was able to solve that service account issue from friday, so that is done :)16:00
dulek:)16:00
dulekkmadac: You can try kubeadm with flannel, it's the simplest thing.16:00
dulekkmadac: And then just generate Kuryr manifests and run them on that K8s cluster. Those will take care of configuring CNI, hopefully it'll be enough.16:01
dulekkmadac: https://docs.openstack.org/kuryr-kubernetes/latest/installation/containerized.html16:02
kmadac@dulek: this is something I dont understand. I thought thah kuryr will replace networking like flannel or calico and will use neutron ports for everything. But is seems it is not true.16:03
dulekkmadac: Why do you think it's not true?16:04
kmadac@dulek: as you can see I'm really beginner in k8s world :(16:04
kmadac@dulek: because you wrote, to try  kubeadm with flannel16:05
dulekkmadac: We simply never applied or implemented Kuryr support in kubeadm.16:05
dulekkmadac: So I'm suggesting flannel as it shouldn't make any significant networking stuff on the nodes besides adding flannel0 bridge.16:06
dulekkmadac: Then once you'll apply Kuryr manifests, the kuryr-cni pods will replace CNI configuration.16:06
kmadac@dulek: ok, so my assumption that no networking like flannel/calico is needed if kuryr is used is correct16:06
dulekkmadac: You might also need to get rid of flannel pods if there are any. Not really sure here.16:07
kmadac@dulek: greate16:07
dulekkmadac: Yeah, it's correct.16:07
kmadac@dulek: what deployment you are using instead of kubeadm?16:08
*** janki has quit IRC16:08
dulekkmadac: DevStack for development, it deploys simplified K8s/OpenShift cluster with hyperkube.16:09
dulekkmadac: For productized stuff I work on we use openshift-ansible, it has Kuryr support implemented, but obviously it's about OpenShift, not vanilla K8s. ;)16:10

kmadac@dulek: hmm I see. Thanks for all the info. I have openstack deployed with openstack-ansible (Rocky) and now I need to integrate k8s running in vms with neutron without overlay networking - this is main customer requirement. I was able to run kuryr-controller and kuryr-daemon without errors, but networking was not working.16:15
kmadac@dulek: i will try  containeraized   way of deployment16:16
*** rh-jelabarre has joined #openstack-kuryr16:18
dulekkmadac: Because you probably needed to configure CNI of your K8s nodes to use Kuryr.16:20
dulekkmadac: https://docs.openstack.org/kuryr-kubernetes/latest/installation/manual.html#configure-kuryr-cni16:21
dulekkmadac: Point about /etc/cni/net.d/10-kuryr.conf.16:21
