| ivc_ | danil kuryr-k8s can be deployed on bare metal. the easiest way to try it is with devstack, but if you want to deploy manually, you'll need to pick an existing Neutron subnet (or create one in openstack) and specify it's project id, pod_subnet id, pod_security_groups ids and ovs_bridge (the name of integration bridge if using openvswitch) | 09:30 |
| danil | ivc_, so what about "worker_nodes_subnet" parameter ?? I can't understand it's meaning | 09:39 |
| ivc_ | danil that one is for k8s running inside vms | 09:41 |
| danil | ivc_, oh, thank you very much | 09:41 |
| *** yuanying has joined #openstack-kuryr | 09:41 | |
| ivc_ | danil np, you can also ignore service_subnet for now, it is not fully merged yet | 09:43 |
| danil | ivc_, oh, pretty good, thanks | 09:44 |
| danil | ivc_, should I specify kuryr.conf on both my machines (controller and compute) ?? | 09:45 |
| ivc_ | danil yes, kuryr.conf is needed for both cni (compute) and controller | 09:53 |
| ivc_ | danil for cni you'll need a conf like this: https://github.com/openstack/kuryr-kubernetes/blob/master/etc/cni/net.d/10-kuryr.conf | 09:55 |
| ivc_ | danil also you might find it useful to take a look at https://github.com/openstack/kuryr-kubernetes/blob/master/devstack/plugin.sh | 09:56 |

| *** limao has joined #openstack-kuryr | 10:01 | |
| danil | ivc_, thank you. To be honest, I hear about this format of conf file for cni in first time. | 10:03 |

| openstackgerrit | Dongcan Ye proposed openstack/kuryr-libnetwork master: Make port bind on dual-stack port https://review.openstack.org/442525 | 10:06 |
| danil | ivc_, and the lust question. What should I do after I specify conf files on both machines ? When I used kuryr with docker, I had to run kuryr server. And what steps here? | 10:06 |
| *** aojea has joined #openstack-kuryr | 10:08 | |
| ivc_ | danil it depends. do you already have openstack and kubernetes both running (and neutron agent running on the same nodes as kubelet)? | 10:08 |
| danil | ivc_, yes, I have openstack and k8s running on 2 physical machines. Also neutron agent running on the same nodes as kubelet | 10:11 |
| danil | ivc_, 1st machine is openstack controller and k8s master, 2nd machine is openstack compute and k8s minion | 10:12 |
| ivc_ | danil ok. then you can run "kuryr-k8s-controller --config-file /path/to/kuryr.ini -d" on controller (-d for debug, otherwise it will be rather silent) | 10:16 |
| danil | ivc_, perfect, thanks a lot. | 10:17 |
| ivc_ | danil other than that, kuryr-cni will be spawned by k8s itself as long as k8s is configured with kuryr's cni and kuryr-cni is installed on minions | 10:17 |
| danil | ivc_, hmm, I don't remember that I configured kuryr-cni...I haven't read about it in documentation. I head only about kuryr.conf. What a file kuryr-cni is ?? | 10:22 |

| *** yamamoto has quit IRC | 10:26 | |
| ivc_ | danil kuryr-cni is a entry-point executable script for kuryr's cni. it is installed as part of kuryr-kubernetes along with kuryr-k8s-controller script. make sure 'which kuryr-cni' works on the compute node and copy that script to kubernetes' cni-bin-dir | 10:26 |
| ivc_ | danil and also make sure you have https://github.com/openstack/kuryr-kubernetes/blob/master/etc/cni/net.d/10-kuryr.conf in kubernetes' cni-conf-dir on the compute too | 10:27 |

| mchiappero | is anyone going to KubeCon? | 15:10 |
| ltomasbo | hi mchiappero | 15:43 |
| ltomasbo | I keep debuging the performance for containers with kuryr and ovs | 15:44 |
| ltomasbo | I was using the out of the box ovs (2.5.0) | 15:44 |
| ltomasbo | and found out that the performance is notably improved when moving to release 2.6.90 (just in case it helps) | 15:45 |
| ltomasbo | I was getting some loop times at the neutron agent of up to 90 seconds with 50 containers booted at the same time | 15:45 |
| ltomasbo | and it was reduced by (at least) 50% with ovs release 2.6.90 | 15:45 |
| ltomasbo | going to keep testing for the nested case | 15:46 |
