| leecalcote | With respect to the VNF Catalog, has consideration been given to leveraging Murano as the catalog? | 02:03 |
| *** bobh has quit IRC | 02:04 | |
| *** lhcheng has joined #tacker | 02:04 | |
| s3wong | leecalcote: we have --- in fact, one of the meetings earlier this cycle, we invited one of Murano's cores to join us | 02:08 |
| s3wong | leecalcote: but after we prioritized our projects in M-cycle, we decided to punt that to later | 02:08 |
| sridhar_ram | gongysh: carrying over from ops-mtg-4 ... lets discuss the time change when we meet in Jan.. | 02:08 |
| *** lhcheng has quit IRC | 02:09 | |
| gongysh | sridhar_ram, ok | 02:09 |
| sridhar_ram | gongysh: does this timeslot work for you on recurring basis ? | 02:09 |
| gongysh | sridhar_ram, yes, the time is good for Chinese guys. | 02:09 |
| leecalcote | s3wong: thanks. Another question - are all the VNFs offered in the catalog represented as Instances/VMs? | 02:09 |
| sridhar_ram | gongysh: sounds good.. | 02:10 |
| sridhar_ram | gongysh: btw, any US travel plans ? we are planning a F2F meetup end of Jan for Tacker in California | 02:10 |
| s3wong | leecalcote: that would depend on the yaml --- you can specify vdu(s) | 02:10 |
| sridhar_ram | gongysh: poll http://goo.gl/forms/8hVPXcmoqz | 02:11 |
| *** mbound_ has joined #tacker | 02:12 | |
| leecalcote | s3wong: VDU = virtual device unit? | 02:13 |
| leecalcote | VDU = a multi-VM VNF? | 02:13 |
| s3wong | leecalcote: former | 02:13 |
| gongysh | sridhar_ram, I have to check with my boss | 02:13 |
| *** sripriya has quit IRC | 02:15 | |
| *** vishwanathj has quit IRC | 02:15 | |
| sridhar_ram | leecalcote: VDU = Virtual Deployment Unit | 02:16 |
| *** bobh has joined #tacker | 02:16 | |
| sridhar_ram | leecalcote: the lingo comes from ETSI MANO | 02:17 |
| leecalcote | sridhar_ram: gotcha. Are the VNF catalog entries essentially HOT templates? | 02:17 |
| leecalcote | and a VDU being a "stack" in HOT parlance? | 02:18 |
| sridhar_ram | leecalcote: they are TOSCA templates.. | 02:18 |
| *** mbound_ has quit IRC | 02:18 | |
| leecalcote | sridhar_ram: got it. in that case, do you use heat-translator to get these TOSCA templates over to HEAT? | 02:18 |
| sridhar_ram | leecalcote: we (Tacker) will absorb some attributes in TOSCA and convert the rest to HOT template using heat-translator.. | 02:19 |
| sridhar_ram | leecalcote: yes, that is the plan .. to use tosca-parser to parse tosca, absorb / alter the objects as needed and send the resulting DOM tree structure to heat-translator.. | 02:19 |
| sridhar_ram | leecalcote: .. this is a work-in-progress | 02:20 |
| sridhar_ram | leecalcote: currently we have a simple in-built tosca -> hot parser.. but that will change in this openstack cycle | 02:20 |
| sridhar_ram | leecalcote: .. with tosca-parser integration work | 02:20 |
| leecalcote | sridhar_ram: makes sense. I just spoke with Matt Rutkowski (IBM) a little last week on the topic. | 02:21 |
| *** bobh has quit IRC | 02:22 | |
| leecalcote | sridhar_ram: Last ignorant question - why Tacker (with VNFs) and not Neutron's FWaaS / LBaaS, etc? | 02:22 |
| sridhar_ram | leecalcote: sorry, didn't understand the question | 02:23 |
| *** arturt has joined #tacker | 02:24 | |
| leecalcote | sridhar_ram: this question is coming from a place of ignorance, so it could be my question.... I get that Tacker is aimed at Telco use cases and provides VNF via instantiation, orchestration, lifecycle management of virtual network appliances (VMs). | 02:25 |
| leecalcote | sridhar_ram: given the functionality provided by those virtual network appliances, why not use Neutron's capabilities for those use Telco cases? | 02:26 |
| sridhar_ram | leecalcote: ah..i get it.. | 02:26 |
| sridhar_ram | leecalcote: Neutron's advanced services is quite restrictive.. Telco's VNFs needs are beyond LB, FW and they are quite eclectic.. you can't imagine going through the effort of introducing Neutron API each and every VNF feature out there... | 02:27 |
| sridhar_ram | leecalcote: a better model is to maintain a catalog of VNFs (a wide variety of them), orchestrate using Tacker and configure either directly or thru EMS to get the network service required | 02:28 |
| leecalcote | sridhar_ram: I see, so other vendor's virtual network appliances (e.g. Cisco CSR 1000v, etc.) provide much richer capabilities and flexibility than Neutron's advanced services do. | 02:29 |
| sridhar_ram | leecalcote: exactly... we both know the rich set of CSR1K features :) | 02:29 |
| *** arturt has quit IRC | 02:29 | |
| sridhar_ram | leecalcote: you can't imagine a neutron knob for everyone of them.. it is not practical | 02:30 |
| leecalcote | sridhar_ram: this conversation quickly become a reminiscing session for the two of us. :) | 02:30 |
| sridhar_ram | leecalcote: totally .. but with the power of opensource behind us! | 02:31 |
| leecalcote | sridhar_ram: excellent. this short conversation really helped quickly solidify my understanding of your efforts. that's great. | 02:31 |
| sridhar_ram | leecalcote: happy to provide my 2cs .. | 02:31 |
| sridhar_ram | leecalcote: time to head home.. | 02:32 |
| leecalcote | sridhar_ram: you guys started in the Juno timeframe (I think)... is Tacker included in Big Tent at this point? | 02:32 |
| sridhar_ram | leecalcote: no, not yet.. it is in the cards | 02:32 |
| leecalcote | sridhar_ram: no joke - hopefully, traffic has died down a bit at this point. | 02:32 |
| leecalcote | sridhar_ram: cool - excellent. I'm rooting for you. :) | 02:32 |
| *** prashantD_ has quit IRC | 02:33 | |
| sridhar_ram | leecalcote: thank you.. ! please do join in our reviews and activities.. your background with all the things we did lends itself well | 02:33 |
| sridhar_ram | leecalcote: ttyl | 02:33 |
| leecalcote | sridhar_ram: quick, last question - is anyone from Mirantis active in Tacker? | 02:33 |
| sridhar_ram | leecalcote: AFAIK, no | 02:33 |
| leecalcote | sridhar_ram: yes - really. | 02:33 |
| leecalcote | sridhar_ram: ok, gotcha.... have a safe drive. ttyl. | 02:34 |

| tbh | bobh, ping | 04:06 |
| bobh | tbh: hello | 04:06 |
| tbh | bobh, I need your help in reviewing my patches and also some directions in tosca parser | 04:07 |
| bobh | tbh: trying to catch up on reviews - I've been way behind | 04:08 |
| bobh | tbh: also working on tosca-parser integration - it's not quite as easy as I had hoped | 04:08 |
| bobh | tbh: I need a patch to land in tosca-parser to allow it to accept a dict for the TOSCA template instead of a file or URL, so that will hold up the associated tacker changes | 04:09 |
| *** leecalcote has quit IRC | 04:09 | |
| tbh | bobh, oh I see, I can parse the new syntax for image creation with existing tosca template, but I need to understand the tosca parser integration well to proceed further | 04:10 |
| tbh | bobh, this is the gist for auto image creation https://gist.github.com/bharaththiruveedula/708c4747fc944dd43bbb with out tosca parser integration | 04:11 |
| tbh | but now I feel it is useless with out tosca parser integration | 04:11 |
| bobh | tbh: thanks - I'll take a look but probably not until tomorrow - getting late here | 04:11 |
| tbh | bobh, if you have time, can you tell me about tosca parser in tacker | 04:11 |
| tbh | bobh, oh okay, I will ask you tomorrow then | 04:12 |
| bobh | plan for tosca-parser integration is in two parts - one is to load the template and invoke tosca-parser when the VNFD is created to check for validity, but template will still be stored in VNFD as it is today | 04:13 |
| bobh | second piece is to load the template in the server at deployment time and check for a version | 04:14 |
| bobh | if no version exists it will use the existing logic | 04:14 |
| tbh | bobh, first task will be done in tacker client? | 04:14 |
| bobh | tbh: yes | 04:15 |
| tbh | bobh, so in the server I will the get the same template as user uploaded(in vnfd creation time) ? | 04:16 |
| *** amotoki has joined #tacker | 04:16 | |
| bobh | tbh: yes | 04:17 |
| bobh | tbh: if there is a version we would use tosca-parser and heat-translator to create the Heat template | 04:17 |
| tbh | bobh, and may I know about "check for version"? | 04:18 |
| bobh | tosca-parser requires a version to be specified in the template - it is specific to the version of TOSCA being used | 04:18 |
| bobh | it will also allow us to use it as a flag for this purpose | 04:18 |
| tbh | bobh, some thing like user(template) ->client(check for validity if yes template(version) else( template) ) -> server(template or template(version)) | 04:20 |
| bobh | tbh: something like that | 04:21 |
| tbh | in server if template(version) invoke heat translator and tosca parser else continue with existing code | 04:21 |
| bobh | tbh: correct | 04:21 |
| tbh | bobh, got it, thanks a lot | 04:22 |
| bobh | tbh: no problem - I'll try to get your reviews done - thanks for all of the effort, we really appreciate it | 04:22 |
| tbh | bobh, yrw :) | 04:24 |
| bobh | tbh: sample of versions line: tosca_definitions_version: tosca_simple_yaml_1_0 | 04:35 |
| bobh | tbh: the version will be different for the NFV profile, but this is a start | 04:36 |
| bobh | tbh: the existence of the tosca_definitions_version: key will trigger the different processing of the template | 04:37 |
| tbh | bobh, this version is available in template? | 04:38 |
| bobh | tbh: yes - if the template contains the line "tosca_definitions_version: tosca_simple_yaml_1_0" we will use tosca-parser / heat-translator - if it doesn't we will use the existing TAcker code - at least that's the theory anyway, we'll see how it works in practice | 04:40 |
| *** bobh has quit IRC | 04:41 | |
| tbh | bobh, because I will continue coding by checking this param | 04:44 |
