longfei_zhangHi, how to disable the debug log info? in the kuryr.conf the "debug = false" , from the cni log i still can see the DEBUG message logged out08:15
longfei_zhang2017-06-22 03:15:42.328 21197 DEBUG kuryr_kubernetes.cni.main [-] Exiting with status 0 run /usr/lib/python2.7/site-packages/kuryr_kubernetes/cni/main.py:9608:15
longfei_zhangwhile the controller log is correct, only the cni logged out the debug message08:19

janonymouslongfei_zhang:Hi,  i am not sure if that is the right way to change, but cni debug could be checked from : http://paste.openstack.org/show/613491/  and debug  parameter could be changed. Please check from that point09:36

foutatorohi all, i'm trying to install kuryr in openstack-ansible using this link https://docs.openstack.org/developer/kuryr/readme.html#running-kuryr09:47
foutatorobut at step running-kuryr: I don't see the script ./scripts/run_kuryr.sh in the cloned project09:48
dmelladofoutatoro: just kuryr or kuryr-kubernetes too?09:48
dmelladohttps://docs.openstack.org/developer/kuryr-kubernetes/installation/index.html09:49
vikascdmellado, i think he is using libnetwork09:49
dmelladovikasc: yeah, that's why I was asking ;)09:49
foutatorodmellado: what's the difference between kuryr and kuryr-kubernetes ?09:49
dmelladofoutatoro: kuryr-kubernetes works with kubernetes as a orchestrator09:50
dmelladoapuimedo: any docs related to the split?09:50
dmelladovikasc: ^^09:51
dmelladofoutatoro: for just docker: check09:51
dmelladohttps://docs.openstack.org/developer/kuryr-libnetwork/readme.html#getting-it-running-with-a-service-container09:51
vikascfoutatoro, kuryr can provide networking to two orchestration tools, docker family, which have libnetwork framework of networking, for those kuryr-libnetwork is the sub project09:51
vikascfoutatoro, another is kubernetes, which has CNM/cni based networking, i.e kubernetes, and for this is kuryr-kubernetes09:52
vikascfoutatoro, both kuryr-kubernetes and kuryr-libnetwork shares a common library which is "kuryr"09:53
dmelladoexactly, so it wouldn't make sense as of now to install just 'kuryr'09:54
foutatorovikasc, dmellado: for my first install  I just want to be able to attach docker containers in neutron network09:54
dmellado:)09:54
vikascfoutatoro, so user will either use, kuryr-libnetwork or kuryr-kuberntes09:54
dmelladogo for kuryr-libnetwork then09:54
vikascfoutatoro, so now to your question, you should clone kuryr-libnetowrk09:55
vikascfoutatoro, https://github.com/openstack/kuryr-libnetwork09:55
vikascfoutatoro, and here is that script, https://github.com/openstack/kuryr-libnetwork/blob/master/scripts/run_kuryr.sh09:56
vikascfoutatoro, sometimes ,incorrectly, we use 'kuryr' to refer to 'kuryr-libnetwork' or 'kuryr-kubernetes' as a short form.09:57
vikascfoutatoro, so you are going to install kuryr-libnetwork09:58
dmelladomaybe we should revisit the docs09:58
dmelladothat's totally true09:58
vikascdmellado, yeah09:58
vikascdmellado, for a newcomer, current state can be quite confusing09:59
vikascdmellado, another thing which we should work on is docs/steps/simplification of configuration parameters09:59
vikascdmellado, there are so many knobs09:59
dmelladoyeah, and now there's even another project, which is kuryr-tempest-plugin :P10:00
vikasc:D10:00
dmelladowhich, in fact is meant for kuryr-kubernetes10:00
dmelladobut the name would've been so long!10:00
dmelladoxD10:00
vikasctrue, though i could not even take a look at it10:00
vikasc:D10:01
vikascfoutatoro, if you still have confusion please let us know10:02
foutatorovikasc, dmellado:  thanks for your feedbacks10:09
foutatorovikasc, dmellado: openstack ansible deploys each openstack service in an lxc container and I created a dedicated lxc container for kuryr.10:09
vikascfoutatoro, great10:09
foutatorovikasc, dmellado: so for you where should be the best place to install docker directly on the bare-metal server (compute node) or into the lxc container of kuryr ?10:10
vikascfoutatoro, where is ovs running? inside lxc container or on baremetal?10:11
foutatorovikasc: the neutron agent run in dedicated lxc container10:12
foutatorobut i'm using linux bridge ml2 plugin10:12
vikascfoutatoro, i would suggest you to first run kuryr on baremetal10:13
vikascfoutatoro, on compute machines10:13
vikascfoutatoro, kuryr should be able to access neutron server (for requesting port creation for containers) and kuryr should be able to access the ovs-int bridge, which neutron agent manages. kuryr will plug container to the ovs-int10:16
foutatorovikasc: hop that kuryr is generic enough to work with linux bridge10:19
longfei_zhangjanonymous, just saw your message, i will check , thx very much10:22
vikascfoutatoro, yes, it will work, https://github.com/openstack/kuryr/blob/master/usr/libexec/kuryr/bridge10:23
vikascfoutatoro, kuryr-libnetwork will use above shared binding script from kuryr repo in bridge case10:24
vikascfoutatoro, here is the supported networking backends, https://github.com/openstack/kuryr/tree/master/usr/libexec/kuryr10:25
vikascfoutatoro, bridge is one of them10:25
foutatorovikasc: openstack-ansible uses self signed certificat therefore the command "docker run --name kuryr-libnetwork ...." fails to authenticate with certificate http://paste.openstack.org/show/613498/10:41
vikascfoutatoro, means kuryr not able to reach neutron server10:44
vikascfoutatoro, please re-check the configuration parameters you provided for neutron api10:45
vikascfoutatoro, limao is not around. he might be the best person to help on kuryr-libnetwork10:47
foutatorovikasc: i think it can not authenticate to keystone due to ssl certificats. my keystone authenticates users through https10:47
vikascfoutatoro, i would suggest to try same parameters from rest neutron client to verify if it works there10:48
vikascfoutatoro, you may be right about ssl certificates10:49
vikascfoutatoro, just to verify steps, install a allinone devstack and see if you get kuryr-libnetwork connected with that10:51
vikascfoutatoro, abot https part apuimedo can confirm10:52

kzaitsev_mbvikasc: saw your review, thanks will try to address the questions soon, but I'm travelling back from my hometown today so it'll take a bit of time12:37
kzaitsev_mbapuimedo: a friendly reminder about releasing schedules: Jul 17 - Jul 21R-612:38
vikasckzaitsev_mb, np :)12:38
kzaitsev_mbFinal release for non-client libraries12:38
kzaitsev_mbhttps://releases.openstack.org/pike/schedule.html12:38
kzaitsev_mbvikasc: I just want to comment right away about the list-vs-dict thing. I can change my implementation to handle lists instead of dicts.12:39
kzaitsev_mbit's just that dicts give you a bit more controll over interface naming12:39
kzaitsev_mbI12:40
kzaitsev_mbI've seen that idea on one of the community meetings. ivc_ mentioned it. I liked it and implemented it that way.12:40
kzaitsev_mbI think it's reasonable to have [vif0, vif1, vif2] to map to [eth0, eth1, eth2] or to have {'eth0': vif0, 'net0': other-vif0}12:41
kzaitsev_mbif we use dicts — the CNI is responsible for giving out iface names. if we do it with dict — the handler is. So, I'd be happy if you'd consider the options =)12:42
kzaitsev_mbI think I'll try to get some attention to the topic during next community meeting =)12:42
apuimedothanks kzaitsev_mb12:43
apuimedoI like dicts more and more12:44
*** yamamoto has joined #openstack-kuryr12:45
*** neiljerram has quit IRC12:45
kzaitsev_mbapuimedo: regarding the schedule — if we want to release new version of kuryr-lib, the deadline is R6, i.e. Jul 17 - Jul 21. Shouldn't apply to kuryr-kubernetes or libnetwork though12:45
kzaitsev_mbfor pike I mean =)12:46
apuimedokzaitsev_mb: thanks a lot for these reminders. I'm notoriously bad at this12:46
apuimedoI'm not sure we need anything for the lib, but we can check it on mOnday12:47
*** neiljerram has joined #openstack-kuryr12:47
vikasckzaitsev_mb, the name in the dict like 'eth0' is vif.name , right?12:48
kzaitsev_mbI think it is. gotta check it though =)12:48
vikasckzaitsev_mb, you are preparing dict from vif objects from pod annotations.. my doubt is that CNI_IFNAME will not match vif.name, even though vif object will be for this interface.12:49
kzaitsev_mbapuimedo: sure. we can make a 0.4.1 (or 0.5.0) with requirements update12:49
vikasckzaitsev_mb, not sure if i was clear enough in asking my query :)12:49
vikascCNI_IFNAME is from cni and vif.name might not match12:50
kzaitsev_mbvikasc: in my particular patch the CNI_IFNAME will always match, since it's currently just one VIF and it's always eth0.12:50
kzaitsev_mbI'm adding functionality on top of that patch in sriov patches12:50
kzaitsev_mblet me show12:50
vikasckzaitsev_mb, even in current code, vif.name does not go as 'eth0'12:51
vikasckzaitsev_mb, and CNI_IFNAME comes as eth012:51
kzaitsev_mbhttps://review.openstack.org/#/c/462455/13/kuryr_kubernetes/controller/handlers/vif.py here12:51
apuimedovikasc: https://review.openstack.org/#/c/476489/212:52
vikasckzaitsev_mb, ok,12:52
kzaitsev_mbhttps://review.openstack.org/#/c/471012/6/kuryr_kubernetes/constants.py here the default vif's name is 'eth0' and here https://review.openstack.org/#/c/471012/6/kuryr_kubernetes/controller/handlers/vif.py it's prepared12:52
vikascnow i see12:52
*** yamamoto has quit IRC12:52
apuimedounfortunately dhellman blocked this approach12:52
vikascyou adding 'eth0'12:52
apuimedoand I'll have to try something more complicated12:53
vikascok ok12:53
*** s1061123 has quit IRC12:53
kzaitsev_mbyeah the logic is a bit convoluted. I tried to split it into multiple patches as cleanly as I could though )12:53
vikasckzaitsev_mb, i was thinking the code as it is now, where 'eth0' does not come from controller12:54
vikasccool12:54
vikasci will take another look12:54
*** gsagie has joined #openstack-kuryr12:54
kzaitsev_mbthanks =) I'll be afk for a while. just booked a plane back to Moscow12:54

vikasckzaitsev_mb, safe journey!12:55
kzaitsev_mbgotta say hello goodbye to my family and catch that plane )12:55
