gampelhi zenoway and scssnow09:57
zenowayhi09:57
scsnowhi, I'm here09:57
gampelThere are few low priority bugs that you guys can tack09:58
yuli_s1i am going to eat09:58
gampelwe are trying to merge this week the SG distributed DNAT and Redis09:58
gampelWere you able to install dragonflow and play with it ?10:00
zenowayOk I've just got started looking at df, not too much familiar with it yet10:00
gampelWe could help you set it up via devstack10:01
zenowayI haven't yet played with it. But AFAIK scsnow did it already.10:01
gampeldo you have any questions  about it or problems ?10:01
zenowayWhat would you recommend to start with? (after installing df with devstack)10:03
*** yamamoto has quit IRC10:03
*** scsnow_ has joined #openstack-dragonflow10:03
gampelI would  recommend playing with it a bit to understand how it works10:04
*** yamamoto has joined #openstack-dragonflow10:04
*** scsnow has quit IRC10:04
gampelstart reviewing  the patches and  because we are in integration phase of many new features10:05
gampelyou probably  will find problems , so report them in a bug and maybe fix them10:05
gampelyou could talk with us about it in this channel and we could think together what to do10:05
gampelwe are going to feature freeze this weekend10:06
scsnow_sorry, I got kicked. I played a bit with df in devstack and have a question. I see, that vrouter implementation does look like as in pre-juno neutron. I mean netns between br-int and br-ex and iptables rules for SNAT/DNAT. It it expected?10:06
zenowayOk, got it. How do you usually report bugs? Do you discuss them (on meetings) before creating bug reports?10:06
gampelNo this is only for N-S10:06
oansonzenoway, you can just add them to launchpad10:07
gampelzenoway:  just report and then we could discuss10:07
gampelE-W l3 is flows and we are adding now DNAT10:07
zenowayOK10:07
gampel scsnow_: we still have the l3-agent for the N-S traffic only10:07
scsnow_Ok, I see10:07
gampelwhen we merge the DNAT patches it will be only SNAT10:08
gampel#linkj https://review.openstack.org/#/c/294374/10:08
gampelhttps://review.openstack.org/#/c/289148/10:08
gampelbest will be to setup multi node10:09
gampelthen you see what is distributed on the compute nodes and what is still centralized10:09
gampelAre you testing DF fro specific environment10:10
gampel?10:10
scsnow_so, at this moment N-S is still centralized and N-W is distributed?10:10
scsnow_sorry, E-w10:10
gampelyes we are now merging Distributed  DNAT floating IP10:11
scsnow_ok, what about snat? Is it going to be centrilized like in DVR?10:11
gampelWe have planed for SNAT but it low propriety is Do you have a need for distributed SNAT ?10:12
gampelCurrently it is low priority for N cycle10:13
scsnow_nope, my goal is to get better understanding of OpenFlow/ryu.10:14
zenowayI have to go to offline now. Thank you for recommendations!10:15
gampelOk no problem let me know when you need my help10:15
*** zenoway has quit IRC10:15
scsnow_one more question. any plans for service chaining in df?10:15
gampelyes it is part of the planes  for N10:15
*** zenoway has joined #openstack-dragonflow10:16
gampelwe have a different  view we call it service injection10:16
*** yamamoto has quit IRC10:16
scsnow_any relationship between neutron-sfc and df?10:16
gampelhttp://www.slideshare.net/gampel/dragonflow-01-2016-tlv-meetup10:16
gampelyes we are going to implement the sfc api as well10:16
gampelwhats use case do you need the SC for ?10:17
*** yamamoto has joined #openstack-dragonflow10:17
scsnow_I work for NEC/NetCracker in NFV area10:17
gampelWhat time zone are you from , i have to go for launch , you could send me questions via e-mail eran@gampel.net10:18
scsnow_We have some R&D activities around SFC. My timezone is GMT+310:18
gampelwe could talk latter I have  to go for launch we can talk latter :)10:18
gampelfeel free to send me e-mail10:18
gampelor catch me latter on the IRC10:19
scsnow_ok, bon appetit. I'll drop you an e-mail. thanks for your time10:19

todinHi, are there any pre build packages of dragonflow for ubuntu 14.04/Openstack Liberty?16:41
*** mastermind has quit IRC16:47
*** mastermind has joined #openstack-dragonflow16:48
gampel1 todin: you could use the Vagrant build16:52

*** mastermind has quit IRC16:52
*** oanson has quit IRC16:54
*** oanson has joined #openstack-dragonflow16:55
todingampel1: I tried that a few days ago, but it didn't work. But back to my question, there are no packages right now?17:01
todinIf I want to use Dragonflow in a bigger environment, I have to build them by my self?17:01
*** oanson has quit IRC17:04
gampel1 yes currently using devstack17:06
gampel1we started automating the deployment  in our test lab but we mostly using devstack at the moment17:07
todingampel1: okay, would you rate Dragonflow production ready right now?17:08
gampel1we hope to have installer and binary packages  for the N cycle17:08
gampel1Thats our goal for the Mitka cycle but it depends on the features  you need17:10
todingampel1: I do not need much feature, ipv4, distributed floating IPs, distributed dhcp. Scale 10000 server, 100.000 Vms.17:12
gampel1todin: ipv4 l2 and l3 are already mature and we are merging distributed DNAT  this week , we have feature  freeze end of this week17:13
gampel1distributed DHCP is mature as well we have it since liberty17:14
todinwill the distributed DNAT go into the Mitaka release?17:15
gampel1we have not tested 10000 servers due,17:15
gampel1yes17:15
gampel1But the scale  is mainly dependent on the pluggable DB and Pub Sub you choose17:15
gampel1yes distributed DNAT will be part of Mitaka17:16
todindo you know anything about the cooperation between the deutsche telekom and Huawai? Do they use dragonflow?17:16
gampel1I know abut it are you from DT17:17
todingampel1: yes, I work in a subsidary of the deutsche telekom17:18
gampel1we are currently in evaluation and testing DF to get into  fusionSphere17:19
gampel1so if we will get in to the FS solution  , and it looks good so far,17:21
gampel1we included in Mitka features that are focused on production and scale17:22
gampel1you can see the features list in http://www.slideshare.net/gampel/dragonflow-01-2016-tlv-meetup17:22
todinthat sounds great, let me check17:23
gampel1DB consistency , selective DB distribution, Pluggable PUB SUB D DNAT controller reliability and some new Distributed DBs mainly redis17:24
gampel1and SG17:25
todindo you do stuff like l2population and arp-responder?17:26
gampel1yes it is all ready in17:26
todinokay, so you say the best way to test it, devstack or the vagrant build.17:27
gampel1yes17:27
gampel1http://docs.openstack.org/developer/dragonflow/specs/ this is the current spec list17:27
todinYou are part of Huawai or DT?17:28
gampel1Huawei17:28
gampel1let me know if you need any help in the setup17:29
gampel1or if you have any questions17:29
todinthe public IPs of the VMs are routed between the compute nodes and the DC core routes?17:32
*** oanson has joined #openstack-dragonflow17:33
gampel1you mean for FIP17:34
todinyes17:34
*** feipeng has quit IRC17:35
gampel1you can see all the details  in  http://docs.openstack.org/developer/dragonflow/specs/distributed_dnat.html17:36
