*** roeyc has quit IRC14:16
regXboirussellb: ack - although, honestly i literally did cut and paste of the old code14:17
*** jckasper has quit IRC14:17
russellbyep, i just don't think it'll take much more time to do it in a way that avoids a new loop over all bindings in binding_run14:17
russellbsort of defeats the purpose of the work you did :)14:17
*** jckasper has joined #openstack-neutron-ovn14:18
regXboium, the only point of that new loop is *just* the all_ports14:18
russellbi understand14:18
*** conner has joined #openstack-neutron-ovn14:18
regXboiyes it's an extra loop, but make it work :)14:18
regXboiand then get fancy14:18
regXboiactually, I have a bunch of patches stacked up on bugs14:18

crherrigesmsg NickServ VERIFY REGISTER crherriges ygnbxhtjtoaj14:40
crherrigeswell now that everyone knows I'm registered...14:44
crherrigesI'd like to add —monitor option to ovsdb-server. Can I do so statically, or would a dynamic solution be preferable?14:46
regXboicrherriges: I just looked at the code again and isn't it already there?14:59
*** jckasper has joined #openstack-neutron-ovn14:59
crherrigesit is, but it is not currently enabled15:01
regXboium... huh?15:01
crherrigesif I run ps aux and grep for ovsdb-server, the monitor does not show up15:02
crherrigesso to test it, I went into ovn-ctl and added --detach --monitor, and ran ps aux again15:04
russellbwhat's your use case?15:04
crherrigesit then showed a monitor, the pid it was monitoring, and it's status15:04
russellbhappy to add stuff, just want to understand15:04
*** yamamoto has joined #openstack-neutron-ovn15:05
regXboiah, so you want ovn-ctl to use --detach and --monitor ?15:05
* regXboi in same boat as russellb at this point15:05
russellbi just had to go read the man page for --monitor, heh15:05
russellbmakes more sense now15:05
crherrigesyes @regXboi15:06
russellbcrherriges: are  you wanting to change the devstack setup, or more generally?15:07
russellbbased on our current systemd unit file, --detach and --monitor does seem like an improvement15:08
russellbit seems like a more ideal case that we'd have systemd fulfilling this function, though15:08
regXboirussellb: right now, ovn-ctl uses --detach for the NB and SB dbs15:08
* russellb nods15:09
regXboiI'm not sure why it didn't just drop that and use start_daemon15:09
russellbi mean adding --monitor would be an improvement15:09
regXboior add --monitor :)15:09
russellbcrherriges: after looking around, i think not using --monitor is simply an oversight.  would you be interested in submitting a patch?15:11
russellblike regXboi suggested above, changing to use start_daemon sounds like the right fix'15:11
russellbor best fix15:11
*** yamamoto has quit IRC15:11
crherrigesI can definitely submit a patch for that15:14
crherrigesso it just needs to be added to start_daemon, is that correct?15:14
*** pcaruana has quit IRC15:17
crherrigesit also seems like northd has the opposite problem15:19
crherriges--detach and --monitor are there, but arent' in the man pages.  not sure if I'm missing something15:20

mesteryrussellb: Is this still valid? http://docs.openstack.org/developer/networking-ovn/containers.html15:36
mesteryrussellb: I don't see instructions on how to boot a container using that port in there though. /cc Sam-I-Am15:36
russellbmestery: it should be still valid, though i haven't tested it since migrating to ML215:49
mesteryrussellb: OK, I'm looking at this, and also seeing if we can make kuryr use it by default with OVN15:49
russellband you're right, it would be really helpful to add a new section that talks about how to make use of this from within the VM15:49
russellbbasically, you've got traffic coming in to the VM with VLAN tags identifying which container the packet is for15:49
mesteryYes!15:49
russellband you need to deal with it :)15:50
* russellb hand waves15:50
* mestery goes to deal with it15:50
russellbi imagine a simple ovs setup15:50
russellbre: kuryr, i know there has been some talk about how they'd use vlan-aware-vms15:50
russellband all of that applies here15:50
mestery+100015:50
russellbthis doc just talks about our ovn-specific vlan-aware-vms implementation15:50
russellbsince we didn't want to wait for the general neutron api to be worked out15:50
russellbthis was a stopgap15:50
mesteryWell, for now it's not even that, just our usage of "binding:profile"15:50
russellbyes, but this binding:profile thing is basically vlan-aware-vms for OVN15:51
mesteryheh15:51
mesteryrussellb: That's because we rock and we're ahead of hte game15:51
russellbpainfully simple approach15:51
russellb(except not painful, really)15:51
*** regXboi has quit IRC15:52
mesteryright15:52
russellbthe code still seems to be in the ml2 mech driver :)15:52
russellbrelated: https://github.com/openvswitch/ovs/blob/master/INSTALL.Docker.md15:53
russellbi think the "underlay" mode makes use of our binding:profile15:53
russellbnot sure if that stuff still works or what ...15:53
* mestery waves hands15:54
russellbyup15:54
mesteryheh15:54
mestery:)15:54
mesteryAs if I needed *more* stuff to do this week15:54
russellbheh, well, this sounds like a fun thing15:55
mesteryYup :)15:55
mesteryFirst step, off to see what kuryr currently looks like15:55
russellbi hear a CNI plugin is imminent for kuryr15:56
russellbgood news15:56
*** banix has joined #openstack-neutron-ovn16:00
mesteryI think it's already there I guess16:00
mesteryLovely. As is always the case, when I got to look at kuryr it's like a giant tire fire16:03
