*** lmdaly has joined #openstack-kuryr14:24
ltomasbowas wondering how to device if trunk ports where to be used for the vlan case, but I already proposed a patch for vlan and trunk ports14:24
ltomasboif you want to take a look14:24
ltomasbo(relies on vikasc patch ofc)14:25
apuimedos/device/decide/ ?14:26
apuimedoltomasbo: ^^14:26
ltomasboyep14:26
apuimedoalso, can you review https://review.openstack.org/#/c/361993/ ?14:26
apuimedoyour code is the consumer, so your +1 here means a lot14:26
ltomasboI assumed that if the vlan driver is to be used, then a subport will be used14:27
apuimedoltomasbo: I think you can assume that for now14:27
apuimedothen we'll move to lmdaly's approach14:27
apuimedo;-)14:27
ltomasboyep, I've been using, testing and reviewning it14:27
ltomasboit works, but there is two 'unsolved' issues with it14:27
apuimedoltomasbo: which?14:28
ltomasbo1.- it leaves the t_cxxxxx device inside the VM when removing the container14:28
ltomasboapuimedo: https://review.openstack.org/#/c/361993/14:28
ltomasbonot a big issue, but once the complete list of vlans is assigned, and it starts again from the mix_value (1-4094), it will start failing14:29
apuimedoltomasbo: I thought vikasc commented that he couldn't reproduce the leftover vlan device14:29
ltomasboit happens to me all the time14:29
ltomasbothe 2nd on is that segmentation_type_drivers/__init__.py does not get the info from kuryr.conf14:30
ltomasboso, it always takes the driver as default (veth)14:30
ltomasboI needed to manually change the default to vlan14:31
ltomasboother than that, it works!14:31
ltomasbovikasc, apuimedo: I think the leftover could be an unrelated thing14:31
apuimedoltomasbo: did you find out what it could be?14:31
ltomasboso happy to merge it without that being fix14:31
ltomasbobut the config file should be read it14:32
ltomasbonot yet, my guess is that the config.py file is in /lib/binding14:32
ltomasbowhile it is being read from /lib/segmentation_type_drivers/14:32
ltomasbobut need to dig a bit more14:33
apuimedook14:33
ltomasbobut the rest should be ok, when that is fix, I'll give the +114:34
ltomasbobtw, I've tried both patches together, with container in different and in the same subnet14:35
ltomasboand it works smoothly14:35
apuimedoltomasbo: I think the segmentation type config should be read and chosen by the calling code in kuryr-libnetwork14:35
apuimedo*config reading14:36
ltomasbook, should that be changed then in vikasc patch? right now it is loaded at __init__.py14:37
apuimedolet me check14:38
vikascapuimedo, i thnk thik can be avoided14:39
vikascapuimedo, because with vlan driver segmentation type will always be vlan14:39
vikascapuimedo, and vxlan driver it will be vxlan14:39
apuimedosure14:39
apuimedono question about that14:39
vikascapuimedo, plus vxlan is not supported in trunk port support yet14:39
vikascapuimedo, so y to add extra knobs to confuse user :)14:40
apuimedoyou either have the driver be picked by the binding type14:40
apuimedoor by the calling code14:40
apuimedobut now it is hardcoded in __init__14:40
apuimedowhich is a bit sketchy14:40
vikascsegmentation type is being picked using binding driver... what is hardcoded?14:42
apuimedowhen you do14:43
apuimedofrom kuryr.lib import segmentation_type_drivers14:43
apuimedoit preloads segmentation_type_drivers.driver to be the vlan one14:43
vikascltomasbo, i dont think think config problem is related to this patch, if use see link_iface, it is not reading this variable also from kuryr.conf. still debugging14:43
apuimedoah no14:43
apuimedoI'm a dumbass14:43
apuimedoit doesn't14:43
apuimedonvmnd14:43
vikascthanks :)14:44
apuimedovikasc: +2 your own patch14:44
vikascyahooo14:44
vikascfinally14:44
apuimedoand with ltomasbo +1 I feel confident enough to +2 and merge myself14:44
apuimedoltomasbo: so please, +114:44
apuimedobut I want bug reports for the leftover devices!14:45
vikascplus we have config file problem14:45
vikascthats another issue14:45
vikasci am working on it14:45
apuimedovikasc: bug report for that too!14:45
vikascsure..14:45
ltomasbobut it is not the config file an issue of including segmentation_types?14:46
ltomasboright now, if the vlan wants to be used, with the current patch14:46
ltomasboyou need to included into kuryr.conf, but also to go to the config.py file and modify the default option to vlan14:46

apuimedoltomasbo: vikasc: can it be because when segmentation_driver is imported is before config has been read?14:48
apuimedoso the 17, 18 lines read the default value instead of the current value?14:48
vikaschttps://bugs.launchpad.net/kuryr/+bug/164485514:48
openstackLaunchpad bug 1644855 in kuryr "COE's not able to read 'binding' section variables from kuryr.conf eg, link_iface and driver" [Undecided,In progress] - Assigned to vikas choudhary (choudharyvikas16)14:48
ltomasbothat could be a good reason14:48
vikasci faced issue with link_iface as well14:50
vikascapuimedo, nope, thats does not seem to be the reason, just tested importing segmentation at last14:51
vikascnow ticket is on my name.. will get back soon on this14:52

ltomasbobut that is a different error, right?15:42
ltomasboor what was the test there?15:43
apuimedoltomasbo: I was trying to just import the module in a clean virtualenv15:47
apuimedoI'm not sure I like that the module can't be imported unless you have the config15:47
*** ajo has quit IRC15:52
ltomasboyep15:54
ltomasboshould that have a default or something?15:54
ltomasboin case the config is not there?15:54
ltomasboI'm also concern about the fact that is supposed to read from the config file, but it is not, that could lead to some difficult to find errors in the future15:55
