| openstackgerrit | M V P Nitesh proposed openstack/python-zunclient master: Replace assertEqual([], items) with assertEmpty(items) https://review.openstack.org/473396 | 12:41 |
| egonzalez | as far i can see, kuryr is the only network driver adn there is no way to use the previous method. am i right? | 12:41 |

| lakerzhou | Hongbin, do you know intel clear containers? https://clearlinux.org/documentation/clear-linux/clear-linux.html | 17:38 |
| hongbin | lakerzhou: yes, a little | 17:56 |
| *** jwcroppe has quit IRC | 17:59 | |
| *** jwcroppe has joined #openstack-zun | 18:00 | |
| lakerzhou | Hongbin, I learned clear containers while updating nfv use cases. | 18:11 |
| hongbin | lakerzhou: yes | 18:11 |
| hongbin | lakerzhou: any comment on the clear container? | 18:12 |
| hongbin | lakerzhou: ok, saw your comment in the etherpad | 18:13 |
| lakerzhou | Hongbin, I also talked with an AT&T people (openstack Helm PTL), seems people are interesting in clear container and similar technologies to run VM workload | 18:13 |
| hongbin | lakerzhou: i see | 18:14 |
| hongbin | lakerzhou: see here: https://blueprints.launchpad.net/zun/+spec/support-secure-container | 18:14 |
| lakerzhou | Hongbin, in that case, existing VNFs can run in "containers" | 18:14 |
| hongbin | lakerzhou: yes, and the "container" is actually a vm | 18:15 |
| lakerzhou | hongbin, sounds great! I did not realize it is clear container | 18:15 |
| hongbin | lakerzhou: yes, mkrai own this BP, she is from intel so is an expert on this area :) | 18:16 |
| lakerzhou | Hongbin, Regarding to NFV use cases, I am trying to three major areas: CPU pinning, SR-IOV, and DPDK. | 18:17 |
| hongbin | lakerzhou: ack | 18:18 |
| lakerzhou | Hongbin, for first use case, docker has enough support. The lack of support to NUMA is not good, but it is not critical for now. | 18:20 |
| hongbin | i see | 18:20 |
| lakerzhou | Hongbin, SR-IOV is an easier implementation comparing with DPDK, but it has more hardware dependency | 18:20 |
| hongbin | i see | 18:21 |
| lakerzhou | Hongbin, I am planning to work through the SR-IOV use-case first, before moving to DPDK. | 18:21 |
| hongbin | lakerzhou: sounds good to me | 18:21 |
| hongbin | lakerzhou: i will see if sudipta could continue the cpu pinning work, if he is not available, i can take it over | 18:22 |
| lakerzhou | Hongbin, there are a few options in SR-IOV implementation. Ideally, we should leverage Kuryr work. | 18:24 |
| hongbin | lakerzhou: i think kuryr's proposal is for k8s only, for the libnetwork, it needs another proposal | 18:25 |
| hongbin | lakerzhou: however, yes, we might need to contribute back to libnetwork for this feature | 18:25 |
| lakerzhou | Hongbin, I also looked at libnetwork SR-IOV support. Proposal is there, but no work done so far. | 18:26 |
| hongbin | lakerzhou: oh, there is a proposal to libnetwork as well? | 18:26 |
| lakerzhou | hongbin, https://github.com/docker/libnetwork/issues/1023 | 18:27 |
| hongbin | lakerzhou: i see | 18:27 |
| lakerzhou | hongbin, the proposal was for docker not kuryr | 18:27 |
| hongbin | interesting | 18:27 |
| lakerzhou | Hongbin, so the main concerns are really how to map between docker SR-IOV network and openstack SR-IOV network | 18:29 |
| hongbin | lakerzhou: i see | 18:30 |
| lakerzhou | Hongbin, I need more time to work it out. I know enough about the configuration of openstack VM Sr-iov, but not enough to connect the docker networking piece to it yet | 18:30 |
| *** catinthe_ has joined #openstack-zun | 18:31 | |
| hongbin | lakerzhou: sure | 18:31 |
| hongbin | lakerzhou: after a quick look at the proposal, it seems it is for the bridge network | 18:31 |
| hongbin | lakerzhou: zun is not using the docker bridge network, it is using the kuryr's network | 18:32 |
| hongbin | lakerzhou: so their proposal might not apply our use cases | 18:33 |
| *** catintheroof has quit IRC | 18:33 | |
| lakerzhou | hongbin, I see. Can you please take a quick look at the mellanox plugin link? | 18:34 |
| lakerzhou | hongbin, https://github.com/Mellanox/docker-passthrough-plugin | 18:34 |
| lakerzhou | Hongbin, I have mellanox equipment, and planning to try out this solution. What do you think the major issue for Zun to adopt this solution? | 18:36 |
| hongbin | lakerzhou: it looks that is also a remote libnetwork driver | 18:38 |
| hongbin | lakerzhou: which is in parallel with kuryr-libnetwrok | 18:39 |
| *** jwcroppe has quit IRC | 18:40 | |
| hongbin | lakerzhou: i think we have two options: 1) support additional network driver in zun (as alternative to kuryr-libnetwork) 2) merge those two drivers into one (that means contribute all the mellanox code to kuryr-libnetwork) | 18:40 |
| hongbin | lakerzhou: from zun's point of view, it create a network with driver (i.e. docker network create --driver kuryr/mellanox ....) | 18:42 |
| lakerzhou | hongbin, thanks for the directions. | 18:43 |
| hongbin | lakerzhou: in addition, the mellanox plugin doesn't have an ipam driver, which is also needed in our cases | 18:43 |
| hongbin | lakerzhou: perhaps, it is possible to run it without an ipam driver, but i have never tried it | 18:44 |
| lakerzhou | hongbin, let me document your comments in the NFV use case page too and look a bit more into option 2. I will try if I can find someone from mellanox to contribute the driver to kuryr | 18:47 |
| hongbin | lakerzhou: sound great. thx | 18:47 |
