| spzala | Hello | 16:01 |
|---|---|---|
| spzala | tbh: topol: bobh_: | 16:01 |
| tbh | spzala, Hi | 16:01 |
| bobh_ | o/ | 16:03 |
| spzala | tbh: bobh_: o/ How are you? | 16:03 |
| bobh_ | spzala: just about recovered from jetlag | 16:04 |
| spzala | tbh: bobh_: hope back to routine after long week in Barcelona | 16:04 |
| spzala | bobh_: :-) cool | 16:04 |
| bobh_ | spzala: are you feeling better? Getting sick while traveling is never fun | 16:04 |
| tbh | spzala, yup, am fine, what about you? | 16:05 |
| spzala | bobh_: yup it was nightmare .. yes, still recovering but much better now. Not back to normal meal yet | 16:05 |
| spzala | tbh: cool, thanks. ^^ I am getting better | 16:05 |
| spzala | Well, so if you guys can fill me on friday's cross project session and any other discussion on parser/translator that would be great. | 16:06 |
| bobh_ | spzala: Actually not much to report - Tacker was looking for substitutionmapping support which is already available, so that was easy | 16:07 |
| spzala | bobh_: thx, Nice | 16:07 |
| bobh_ | spzala: they would like to move some of their custom node types into the tosca-parser but I suggested that needs to wait until the next version of the NFV template is released | 16:08 |
| spzala | How about Senling / AutoScaling in general ? | 16:08 |
| bobh_ | spzala: unless they want to maintain their custom nodes in a tosca-parser extension | 16:08 |
| bobh_ | spzala: The Senlin discussion was interesting - it's still not entirely clear what the benefits are - I think they are going to try to do a PoC to demonstrate how it is supposed to work | 16:09 |
| spzala | bobh_: sure, yes if it's something they wanna do right away | 16:09 |
| tbh | spzala, and one more thing which I have to test from my side for confirmation, is how to refer outputs of child templates in parent template | 16:09 |
| tbh | spzala, I mean in nested templates case | 16:09 |
| spzala | bobh_: OK, that's interesting I hope there is a good use case | 16:09 |
| bobh_ | autoscaling that would be needed | 16:10 |
| spzala | tbh: OK, I guess that's where we need create new APIs | 16:10 |
| bobh_ | Darn - lost a whole line of text | 16:10 |
| bobh_ | spzala: It's not clear to me why anyone would move to Senlin as long as Heat still supports autoscaling - but if/when Heat deprecates autoscaling that would be needed | 16:10 |
| spzala | tbh: Mathiue mentioned he will be adding new APIs under https://review.openstack.org/#/c/342675/ so if you can review the patch please as you get time that would be very helpful. | 16:11 |
| bobh_ | spzala: another issue with nested templates is the need for the server invocation of heat-translator to be able to access all of the child templates | 16:11 |
| spzala | APIs to access template and related child templates | 16:11 |
| bobh_ | spzala: it would be interesting if we could generate the child heat templates as additional documents in the same YAML stream using the YAML multiple document feature (--- markers) | 16:12 |
| tbh | spzala, sure, added to my bucket | 16:12 |
| aloga | spzala: good to see that you're recovered :) | 16:12 |
| spzala | bobh_: sure, so that's where I guess my above comment on APIs can fulfill the need I guess | 16:12 |
| bobh_ | spzala: I'll take a look at the patchset. It would be helpful if Heat could accept a multi-document YAML file that contained all of the nested templates inline | 16:13 |
| tbh | bobh_, yes that will solve many issues | 16:13 |
| spzala | aloga: Hey, :) glad you joined and thanks yes much better. Friday night turned out to be worst and one point thought of cancelling the flight but after consulting airport pharmacy few hours in advance of flight and getting some medicine and electrolytes, made it to home :) | 16:14 |
| spzala | bobh_: agree, though for now the decision is Heat wouldn't deprecate any AutoScaling support but the same time no new support is going to added | 16:14 |
| spzala | tbh: Thanks and yes agree! | 16:15 |
| spzala | bobh_: I believe Heat lets you do it by setting required templates as environment -e option | 16:16 |
| spzala | bobh_: and there is an alternative to -e is there too | 16:16 |
| spzala | so we should be easily (hopefully) invoke heat with multiple templates output from translator | 16:17 |
| spzala | bobh_: thanks on patch review | 16:17 |
| spzala | bobh_: tbh: so for multiple template output let's write a blueprint? and have see we all are good with the design | 16:19 |
| spzala | tbh: you are on top of it and I think as of today we are producing multiple templates and since we place them at the same location, auto deployment seems working too | 16:22 |
| spzala | tbh: but the problem is to access them and that's what new APIs will solve | 16:22 |
| bobh_ | spzala: My only concern was how a server invocation of Translator would access the multiple files | 16:22 |
| spzala | tbh: so I guess in a way we are good with this approach | 16:22 |
| spzala | bobh_: I think that's where we need to specify the child template in environment | 16:24 |
| spzala | bobh_: APIs will more like solving problem for Tacker or anyone to access all related template but you are right it doesn't solve the invocation | 16:24 |
| bobh_ | spzala: that's why I was thinking about the multiple documents in a single file/stream YAML feature - might work | 16:25 |
| spzala | bobh_: well, but something Heat won't take. So using the current support from heat using environment should be good idea.. need to dig more though | 16:27 |
| spzala | http://docs.openstack.org/developer/heat/template_guide/environment.html | 16:27 |
| tbh | spzala, yes agree | 16:28 |
| spzala | tbh: sure thanks! | 16:28 |
| spzala | bobh_: tbh: and I had some talk to Kanagaraj (who is long timer heat core) | 16:29 |
| spzala | tbh: I guess you did propose a similar idea of writing multiple docs into same YAML stream and it wasn't found as good approach with current heat support? | 16:30 |
| tbh | spzala, yes, that's the feedback I got from heat guys | 16:30 |
| spzala | tbh: thanks | 16:31 |
| spzala | tbh: I guess not just Raj but you did talk to folks on heat channel | 16:31 |
| spzala | bobh_: as long as we can make invocation work I guess we are on same page right? regardless of a specific approach? | 16:32 |
| tbh | spzala, yes | 16:33 |
| bobh_ | spzala: yep - as long as it works I don't particularly care how - the multi-doc YAML approach is cleaner but if Heat doesn't support it then it doesn't really matter | 16:33 |
| spzala | tbh: thanks! can you please continue owing that space for child templates support with some example template you have already created? I guess you are but just to make sure that we don't wait on each other :) | 16:35 |
| spzala | bobh_: yep agree | 16:35 |
| tbh | spzala, you mean to check the child templates support? | 16:36 |
| spzala | For Senling specific translation, for now user has to go through use of tosca.policies.Scaling.Cluster | 16:37 |
| spzala | as otherwise we don't know whether we doing Heat AutoScalingGroup or Senlin resource | 16:37 |
| spzala | but I guess at this point no body has any problem there | 16:37 |
| spzala | tbh: yes, to make sure that we can use -e or other nested template behavior needed by Heat to deploy translated template where output has a main plus child template | 16:39 |
| spzala | tbh: hope that makes sense? | 16:39 |
| spzala | tbh: I will be glad to help with as well if you need me | 16:39 |
| tbh | spzala, got it, sure I will reconfirm that again | 16:40 |
| spzala | tbh: cool, thanks!! | 16:40 |
| spzala | tbh: bobh_: heat translator has generated good interest from few other folks whom unfortunately I couldn't meet on scheduled Friday meeting but meeting them early next week, I will be updating soon I have more info. | 16:41 |
| spzala | tbh: bobh_: anything else that we need to discuss today? | 16:42 |
| tbh | spzala, sure, that will be helpful | 16:43 |
| spzala | thanks again both for filling me on summit discussion | 16:43 |
| tbh | spzala, that's all from my side | 16:43 |
| bobh_ | spzala: nothing here | 16:43 |
| spzala | tbh: yep it's great and sure will be doing it as soon as I can, if possible I will have them on IRC meeting next week | 16:44 |
| spzala | bobh_: tbh: Cool | 16:44 |
| spzala | bobh_: tbh: thanks again guys!! | 16:44 |
| spzala | aloga: still there? | 16:45 |
| spzala | aloga: I guess dinner time for you :) | 16:45 |
| spzala | bobh_: tbh: bye for now! | 16:46 |
| tbh | spzala, bye | 16:46 |
| spzala | tbh: no Diwali vacation this week for you? | 16:46 |
| spzala | :-) I guess it used to a week of holidays | 16:46 |
| tbh | spzala, it's already over | 16:47 |
| spzala | i.e. holidays (not vacation) | 16:47 |
| spzala | tbh: :) OK | 16:47 |
