s3wongsridhar_ram: why did we need Jinja?  :-)00:52
s3wongsridhar_ram: done00:53
sridhar_rams3wong: old vestige !00:53
sridhar_rams3wong: thanks00:53
s3wongsridhar_ram: I mean, jsonRPC I can understand --- perhaps in some way you want to use that as a transport mechanism for some messaging between server and agents00:54
s3wongJinja, I don't understand...00:54
s3wongAnyway :-)00:54
sridhar_ramJinga was used for device-template00:55
s3wongTrue, it may be useful for configuration template...00:55
sripriya_interestingly it supports LaTeX or JavaScript formatting also00:56
s3wongsripriya_: extremely powerful and flexible interface!00:57
sripriya_s3wong: yes00:58
s3wongsripriya_: speaking of which --- today we do config push by having text in the TOSCA file, right?00:59
s3wongi.e., we get device config from tosca?00:59
sripriya_s3wong: yes, config is a tosca yaml file01:00

sripriya_tbh: hello, sridhar_ram1: should be able to answer that question01:09
*** sridhar_ram1 is now known as sridhar_ram01:09
sridhar_ramtbh: let me check my notes01:09
sripriya_tbh: until https://review.openstack.org/#/c/232693/ merges, you can download the config yaml from gerrit and try it with vnf-create01:10
sridhar_ramtbh: see https://github.com/stackforge/tacker/blob/master/tacker/vm/mgmt_drivers/openwrt/openwrt.py#L3501:12
sridhar_ramlooks root user and empty passwd01:12
tbhsridhar_ram thanks I will try with that01:18

tbhsripriya: Hi18:02
sripriyatbh: hello18:02
tbhsripriya: I didn't face any problem while passing config-file at vnf-create18:03
tbhsripriya: and I can see the configuration in vdu18:03
tbhsripriya: but has problems when using --config18:04
sripriyatbh: that is awesome to hear.18:04
tbhsripriya: I used this command for that http://paste.openstack.org/show/475897/18:04

sripriyatbh: what was the error with --config?18:09
tbhsripriya: I lost my connection18:10
sripriyatbh: can you elaborate?18:10
*** bobh has quit IRC18:10
tbhsripriya: I mean is that command correct?18:11
*** sridhar_ram has joined #tacker18:13
tbhsripriya: if I ran that command, I got stack not found error18:14
sripriyatbh: let me run the command you pasted18:15
tbhsripriya: sure18:15
tbhsripriya: if that is a correct format, I got a fix for that18:16
tbhsripriya: but not sure is that the correct format or not18:16
sripriyatbh: the format is correct, but the code is not handling when the config is passed as a string18:19
*** santoshkumark has joined #tacker18:19
tbhsripriya: this is the diff I have used to make it work, http://paste.openstack.org/show/475910/18:21
tbhsripriya: can you test with this if that is working for you?18:22
sripriyatbh: sure18:23

sridhar_rambobh: hi there.. looks we already have a devref from tbh for health-mon18:27
sridhar_ramhttps://review.openstack.org/#/c/226899/2/doc/source/devref/monitor-api.rst18:27
bobhsridhar_ram: I thought I remembered seeing something18:27
sridhar_rambobh: tbh: I think this covers the devref requirement for health mon spec18:28
tbhsridhar_ram: need to update the description for a couple of methods18:28
openstackgerritMerged stackforge/tacker: Add config-openwrt-with-firewall file to samples  https://review.openstack.org/23269318:31
sridhar_ramtbh: sounds good18:31
sridhar_ramtbh: btw, for http-ping what is your plan for adding unit-tests ?18:31
tbhsridhar_ram: I gave a try for that, but need some basic unit test case for monitoring framework, so that I will change monitoring driver param in vnfd template18:33
tbhand then will write a fake http handler and asser the response text18:33
*** bobh has quit IRC18:33
*** bobh has joined #tacker18:34
tbhthis is my plan of unit test case18:34
trozetsridhar_ram: ping?18:34
tbhbut need some help for basic setup18:34
tbhsridhar_ram:  does it make sense?18:34
sridhar_ramtbh: sorry, I'm back.. yes, it make sense. bobh is planning to add unit-test in a followon patchset to health-mon..18:38
sridhar_ramtbh: you can build yours based / extends that18:39
tbhsridhar_ram: I will update it when I got that base unit case18:39
sridhar_rambobh: tbh: lets plan to land all the health-mon patchsets soon (https://review.openstack.org/#/c/224384/, https://review.openstack.org/#/c/226899/, https://review.openstack.org/#/c/229858/)18:40
sripriyatbh: i just used the same config you provided in pastebin and tried to do vnf-create using that. yaml complained about the string, i observe that vnfd-create using direct yaml string does not do anything to take of string_escape, i'm suspecting some problem with the way the format is provided. i need to debug further18:41
sridhar_rambobh: tbh: .. and plan follow on patchset for these two unit-test18:41
sridhar_ramtrozet: pong, what's up ?18:41
trozetsridhar_ram: I started refactoring the code into proper extensions/plugins: https://github.com/trozet/tacker/commit/ff5cf000e50ee08be402ddc9b65861eea848a7e818:42
trozetsridhar_ram: going to test it out and fill in missing pieces, but had a question about the db18:42
sridhar_ramtrozet: that's cool.. shot the questions!18:43
tbhsridhar_ram: I got the string error, but when I tried to use string escape it works well18:43
trozetsridhar_ram: was wondering if we should create DB entries in tacker for SFC stuff, or should we rely on the DB of the provider?18:43
tbhsorry sripriyaI got the string error, but when I tried to use string escape it works well18:44
tbhsridhar_ram: then the unit test case will be another patchset18:44
sripriyatbh: i see, let me confirm if the string is provided in the right format before we provide the fix18:45
tbhsripriya: sure18:49
sridhar_ramtrozet: what you mean by DB of the provider ? You mean .. ODL's DB ?18:55
trozetsridhar_ram: yeah18:55
openstackgerritbharaththiruveedula proposed stackforge/tacker: API Documentation for Monitoring Framework  https://review.openstack.org/22689918:55
trozetsridhar_ram: it would mean we dont duplicate db info, but we assume that the provider of sfc always keeps its own db18:55

sridhar_ramtrozet: hmm..18:58
openstackgerritbharaththiruveedula proposed stackforge/tacker: API Documentation for Monitoring Framework  https://review.openstack.org/22689919:01
sridhar_ramtrozet: I'm wondering if we can get away w/ the relay, but the challenge is when we retry / respawn VNF chains (tacker supports them as part of auto-healing) .. we need to re-apply the chain19:02
sridhar_ramtrozet: ... to retry sfc chains we need them in the db19:02
trozetsridhar_ram: right19:02
trozetsridhar_ram: if you want tacker to have more intelligence to do operations when the provider is in an invalid state it has to cache the info19:03
trozetsridhar_ram: OK ill do the db part too19:03

*** bobh__ has joined #tacker19:04
*** bobh has quit IRC19:04
sridhar_ramtrozet: sounds good..19:04
trozetsridhar_ram: so when you do operations from the client for VNFs like list VNFs you only poll tacker db right and not the driver?19:04
sridhar_ramtrozet: yes19:04
trozetsridhar_ram: ok thanks19:04
sridhar_ramtrozet: health mon pieces running in the background could change the "states" in the db... but tacker db is the place of truth for now19:05
trozetsridhar_ram: got it19:10
