Hi,
Thank you all for a constructive discussion at the Shanghai PTG. First of all I want to clarify that the Neutron improvements in bulk port creation code I talked about were only merged in Stein and are not available in Queens. Sorry about that, my mistake.
Below I want to list some highlights from the discussion.
- There seemed no pushback on switching to independent release model, so I'll follow up on that soon.
- We discussed using RPC instead of API polling to detect when port becomes ACTIVE in Neutron (https://review.opendev.org/#/c/669642/). I commented on the review with a follow up that came from discussion with Neutron team. Apparently there are 2 better ways of doing this. Let's continue that discussion on the review.
- We know that we don't support running as a second CNI plugin on Multus because of eth0 being hardcoded as interface name and kuryr- controller handling pods that do not had CNI requests. This is something to solve.
- Apparently we all suffer the same problems with Neutron performance when starting a bigger workload on Kuryr-configured K8s cluster (think big Helm chart, multiple operators or simultaneous test suite). This all comes to reducing the number of calls to Neutron. We still don't see a feasible solution to solve this problem, but it seems to be a priority for both Samsung and Red Hat at the moment.
Let's see if we'll meet again in Vancouver!
Thanks, Michał
