gongyshs3wong, hi02:34
s3wonggongysh: hello02:35
gongyshs3wong, can you help to review https://review.openstack.org/#/c/255160/02:35
gongyshlack your +202:35
s3wonggongysh: OK. Will take a look later tonight02:36
gongyshthanks02:36
gongyshs3wong, I want to use sfc, where to begin?02:36
s3wonggongysh: with Tacker? the code hasn't been checked in yet02:37
gongyshI mean in openstack.02:37
s3wonggongysh: with networking-sfc from Neutron. You can start by looking at http://docs.openstack.org/developer/networking-sfc/02:38
s3wongI believe it is (relatively) up to date02:38
s3wonggongysh: particularly  https://wiki.openstack.org/wiki/Neutron/ServiceInsertionAndChaining, look for "networking-sfc installation steps and testbed setup"02:39
s3wongseveral members of the team had replicated a working setup with this instruction. Hopefully it would work for you as well02:39
gongyshdo we have drag and drop to stitch the elements to form a SFC?02:40
s3wonggongysh: Horizon checkin seems to lack behind the server02:41
s3wonggongysh: and this is port based, so you would have to drag-and-drop Neutron ports :-)02:41
gongyshOn SFC, what  are other solutions for insertion other than the networing-sfc way?02:42
s3wonggongysh: with Neutron? nothing convenient02:44
s3wonggongysh: I believe GBP folks did it with stitching subnets together --- as I am no longer a core for that team, I don't know the detail on how they accomplish this02:46
s3wonggongysh: I was told it only works for one chain...02:46
gongyshs3wong, what is the ODL service chain's way?02:47
s3wonggongysh: they have flow classifier02:48
s3wonggongysh: backend is OVS. So basically flow programming02:48
s3wonggongysh: they also have their own OVS fork which supports NSH02:48
s3wong(but that is only useful for carrying information from SF to SF, not necessarily the plumbing part)02:49
gongyshs3wong, does not networking-sfc support a kind of classifier?02:50
s3wonggongysh: networking-sfc does02:50
s3wonggongysh: actually slightly less comprehensive (or, if you are a class half full type of person --- simpler)02:50
s3wong* glass instead of "class"02:50
s3wonggongysh: when trozet did the spec writeup (and code) for Tacker VNFFG, he used the ODL SFC flow classifier as our interface02:51
s3wonggongysh: it apparently uses a netvirt sfc backend for flow classifier... I don't know the detail there, unfortunately02:52
gongyshs3wong, thanks02:54

dkushwahaI was trying to  deploy stable/Liberty tacker code, one my existing openstack environment. So I executed unstack.sh then clean.sh and make sure that there is no tacker directory in /opt/stack/ . After that I have updated to local.conf with entry: enable_plugin tacker https://github.com/openstack/tacker stable/liberty Now while executing ./stack.sh, tacker failing to start With an error: ERROR: Unable to load tacker from configuration file /etc/tacker13:32
dkushwaha/api-paste.ini. Am I doing wrongly? Please suggest.13:32

sripriya__dkushwaha: tacker liberty branch needs to be installed with devstack liberty. the error you are seeing for olso middleware was recently fixed for tacker liberty.17:24
dkushwaha_sripriya__, ok, Thank you.17:39
