jankiHi08:51
jankiI am trying to install tacker devstack master08:51
jankithe installation fails with below error08:52
jankiVimConnectionException: Discovery of client versions failed.08:52
tbhjanki, Hi09:08
tbhjanki, can you paste extra logs?09:09
jankitbh: Hi09:13
jankiI have filled a bug at https://bugs.launchpad.net/tacker/+bug/157769309:14
openstackLaunchpad bug 1577693 in tacker "Devstack tacker installtion fails" [Undecided,New]09:14
jankitbh: and attached logs there09:14
tbhjanki, ah thanks for raising the bug!09:16
jankitbh: please let me know if more logs are needed09:16
tbhjanki, sure, checking09:16
*** gongysh has joined #tacker09:19
*** zeih has quit IRC09:21
tbhjanki, can you provide tacker.con?09:24
tbh*tacker.conf09:24
tbhjanki, to check for the value of auth_url in tacker.conf09:27
jankitbh: Added the file in the bug comments09:27
tbhjanki, thanka09:27
jankitbh: welcome, I am also looking into the issue parallely09:29
tbhjanki, sure09:29
jankitbh: it looks keystone client version is an problem here09:29
tbhjanki, yup09:30
tbhjanki, this call gives the error https://github.com/openstack/tacker/blob/99442f64573e04ca4273a8d14595f396699d1ccf/tacker/nfvo/drivers/vim/openstack_driver.py#L6609:31
tbhjanki, looking at what makes him throw this error09:32
jankitbh: get_version function at https://github.com/openstack/tacker/blob/master/tacker/vm/keystone.py rasies exception09:33
tbhjanki, can you try this in your python shell, https://paste.kde.org/picnsbafn09:36
jankitbh: sure, give me a minute09:37

tbhjanki, disconnected, did I miss anything?09:44
jankitbh: I need to have keystone running for this?09:45
tbhjanki, same problem here09:45
jankitbh: with Devstack failing, how to run keystone?09:45
tbhjanki, setting up the devstack09:45
tbhjanki, it will setup keystone first09:45
tbhjanki, by now you must have keystone running09:46
jankitbh: I tried restacking the devstack09:46
tbhjanki, okay09:46
jankitbh: it is now failing with other error09:46
tbhjanki, what is that09:47
janki tbh: Could not satisfy constraints for 'python-tackerclient': installation from path or url cannot be constrained to a version09:48
jankitbh: I was getting this error earlier. so started with a fresh devstack vm and got the Vimconnection error as described in the bug09:49
tbhjanki, OFFLINE=True ?09:50
jankitbh: no09:50
tbhjanki, basically I got this error, when I set OFFLINE=True flag in local.conf09:50
jankitbh: I tried running stack with pre-cloning tackerclient and horizon and yet was getting the same error09:51
tbhjanki, so I am just cross checking09:51
jankitbh: I am getting this since last week under different scenarios like with horizon enabled and disabled09:51
jankitbh: so today I started a fresh vm devstack installation and still got the error09:52
tbhjanki, yeah I agree, this devstack gives some weird errors sometimes09:53
jankitbh: ran the code, got this output09:54
janki<keystoneclient.v3.client.Client object at 0x7f1ff7d66ed0>09:54
*** manikanta_tadi has joined #tacker09:54
jankitbh: I ran this09:54
jankifrom keystoneclient import client keystone_client = client.Client(auth_url='http://10.66.30.67:35357') print keystone_client09:54
tbhjanki, and store that value in a variable09:55
tbhokay09:55
tbhprint keystone_client.version09:55
jankiv309:55
jankitbh: the version is v309:55
tbhjanki, yeah now that's why didn't get that error09:56
tbhjanki, just cross checking, cd /opt/stack/python-tackerclient && git branch09:57
jankitbh: master09:59
tbhjanki, everything seems good10:00
jankitbh: could proxy be an issue?10:00
jankitbh: but I have installed tacker before and was not getting this error10:01
tbhjanki, seems like bug in pip10:03
tbhjanki, but not sure10:03
tbhjanki, can you upgrade the pip and try again?10:03
jankitbh: sure will do10:04
jankitbh: pip is laready latest version 8.1.110:09
*** zeih has joined #tacker10:13
tbhjanki, hmm, am using the same version10:40
jankitbh: I am trying to debug by adding log lines at appropriate places10:44

jankitbh: I have added the solution in comments, what about the status of the bug?12:33

*** tbh_ has joined #tacker12:37
*** tbh has quit IRC12:39
tbh_janki, can be marked as invalid12:40
tbh_janki, as that error is because of keystone?12:41
*** tbh_ has quit IRC12:43
*** tbh_ has joined #tacker12:44
jankitbh_: the error was because tacker couldnot get keystoneclient's version due to proxy12:45

trozetsridhar_ram: can you point me to the patches for NFVO plugin/extension?16:12
sridhar_ramtrozet: it went in as part of multisite feature...16:12
* sridhar_ram is looking up16:12
sridhar_ramtrozet: https://review.openstack.org/#/c/285096/16:13
trozetsridhar_ram: thanks16:14
sridhar_ramtrozet: sure, it is here in the codebase .. https://github.com/openstack/tacker/blob/master/tacker/nfvo/nfvo_plugin.py16:15
trozetbig patch :)16:15
sridhar_ramtrozet: indeed... multisite is non-trivial + the initial scaffoldings for NFVO16:15
trozetsridhar_ram: does this also generalize VIM type?16:16
sridhar_ramtrozet: yes, VIM type is now an input in the add-vim dialog / workflow16:17
sridhar_ramtrozet: ofcourse, we only support "openstack" VIM type..16:18
sridhar_ramtrozet: .. for now16:18
trozetsridhar_ram: so is it in the spec i guess how the vnfm now picks which driver to use based on VIM type?16:18
sridhar_ramtrozet: yep16:18
trozetsridhar_ram: this is kind of weird: https://review.openstack.org/#/c/285096/15/setup.cfg16:19
trozetsridhar_ram: you abstract VIM, but keep heat driver16:19
trozetsridhar_ram: seems like the openstack drivers should be moved to an openstack VIM driver folder or something16:20
sridhar_ramtrozet: there is a refactoring item in our queue to merge heat driver into the openstack driver16:20
*** sbalakri has joined #tacker16:20
trozetsridhar_ram: rings a bell from the working session :)16:21
sridhar_ramtrozet: :)16:21
trozetsridhar_ram: should I abandon this then? https://review.openstack.org/#/c/286802/16:22
trozetsridhar_ram: or just rebase it and rip out all the vnffg specific plugin/extension16:22
sridhar_ramtrozet: I'd suggest rebase + rip as it will leave an audit trail for traceability16:23
trozetsridhar_ram: ok.  going to wait until spec goes through.  I'll update that either today or tmrw16:24
sridhar_ramtrozet: sure..16:24

sripriyatrozet: ping20:01
trozetsripriya: hi20:02
sripriyatrozet: i just caught up on the api discussion for vnffg20:02
trozetsripriya: oh, ok20:02
*** sridhar_ram1 has joined #tacker20:03
sripriyatrozet: i looked in to your spec and i had a question regarding the extended vnffg resources20:03
trozetsripriya: sure20:03
sripriyathe ones like nfp, chain and classifier, how do you plan to handle them at the API level?20:03
*** sridhar_ram has quit IRC20:04
sripriyatrozet: these resources have just a GET call the user can do from the API right?20:04
trozetsripriya: well we could remove the chain and classifier, they would essentially be the same thing as doing the show in networking-sfc with the ID20:05
trozetsripriya: but for nfp, it would list the IDs of the associated chains/classifiers (and those IDs should come from networking-sfc)20:05
trozetsripriya: yeah i just wanted to give a user a way to see chain and classifier info from an nfp20:05
trozetbut i guess that is duplicating networking-sfc20:06
trozetsripriya: what do you think?20:07
sripriyatrozet: yeah, i have been thinking as well about handling these resources at the tacker api level20:07
trozetsripriya: so you think I should remove rest access to the chain and classifier, and just let the user get the IDs from the nfp and do a lookup via neutron client?20:09
sripriyatrozet: give me little time to think about this, i wll get back to you20:14
trozetsripriya: ok thanks20:14
sripriyatrozet: other than this, for the main vnffg resources, they will be moved up nfvo extension right20:15
sripriyatrozet: did you need any further clarification on that?20:15
trozetsripriya: no don't think so.  sridhar_ram1 pointed me to the patch this morning20:15
sripriyatrozet: cool, the vnffg resources and the CRUD api just moves to the nfvo interface/plugin as is. please ping me if you need any further help. i presume you will be changing the spec with these changes?20:17
trozetsripriya: yeah.  I already had this patch that added the extension and was passing jenkins :( https://review.openstack.org/#/c/286802/20:18
trozetsripriya: going to refactor that one to go into the nfvo plugin20:18
sripriyatrozet: i can totally relate to it :-(20:19
trozetsripriya: oh i guess I do have a question...although I havent looked yet.  Shoudl I keep the vnffg_db as separate20:19
trozetsripriya: so nfvo plugin will inherit it as as separate db?20:19
trozetsripriya: or is there a single nfvo db20:20
sripriyatrozet: the latter case20:20
trozetah ok20:21
trozetthanks20:21
sripriyatrozet: https://github.com/openstack/tacker/blob/master/tacker/db/nfvo/nfvo_db.py they need to be added here...20:21
trozetsripriya: ok got it20:22
