| apetrich | I think I've reviewed and tried them before the rebase | 09:28 |
| rakhmerov | d0ugal, apetrich: what are you guys up to? | 09:40 |
| rakhmerov | I wonder if I missed anything important | 09:40 |
| apetrich | I'm trying and failing at getting a good base on https://blueprints.launchpad.net/mistral/+spec/sample-custom-action-project | 09:42 |
| d0ugal | rakhmerov: I am actually just trying to decide what to do :) | 09:43 |
| rakhmerov | aah! ) | 09:43 |
| rakhmerov | interesting | 09:43 |
| d0ugal | After milestone 2 I don't have anything I am working on now | 09:43 |
| rakhmerov | I need to write some docs for the internal purposes, I'll spend a few next days on that | 09:44 |
| d0ugal | Lots of things I started before that I need to finish | 09:44 |
| rakhmerov | after that I'll be working on improving Scheduler | 09:44 |
| rakhmerov | d0ugal: yeah, I see | 09:44 |
| d0ugal | Too many things to pick from :) | 09:44 |
| pgaxatte | d0ugal: didn't see your response. I'm wondering how people deploy mistral in a multi-region environment | 09:49 |
| d0ugal | pgaxatte: Interesting. Sorry, I don't have any experience with that. | 09:50 |
| d0ugal | rakhmerov: ^ Do you? | 09:50 |
| pgaxatte | if they deploy one endpoint per region or a global endpoint for all regions | 09:50 |
| rakhmerov | d0ugal: unfortunately no | 09:53 |
| pgaxatte | rakhmerov do you know of anyone using mistral on multiple regions? | 09:54 |
| pgaxatte | i know CERN uses mistral but i have no idea if they use regions or not | 09:54 |
| rakhmerov | pgaxatte: no, not really | 09:54 |
| rakhmerov | I don't know that too | 09:55 |
| rakhmerov | well, lots of people use Mistral but many use it w/o auth at all | 09:55 |
| rakhmerov | as far as regions, hm.. thinking | 09:55 |
| rakhmerov | if someone comes to my mind I'll let you know | 09:55 |
| pgaxatte | rakhmerov: thanks i'm really hoping on some feedback | 09:56 |
| d0ugal | rakhmerov: I guess maybe kong did, because he had some patches related to it | 09:56 |
| d0ugal | but he isn't in here anymore :( | 09:56 |
| pgaxatte | and this question comes with a second one: how do you scale out Mistral? | 09:57 |
| rakhmerov | d0ugal: yes! Right | 09:57 |
| d0ugal | oh, lxkong - maybe he is still here. | 09:57 |
| rakhmerov | pgaxatte: adding more engines and executors | 09:57 |
| rakhmerov | :) | 09:57 |
| pgaxatte | i guess the tricky part is the cron scheduler? | 09:57 |
| rakhmerov | pgaxatte: well, there are two things in Mistral and they shouldn't be confused | 09:59 |
| rakhmerov | one is Cron Trigger | 09:59 |
| rakhmerov | it's the part of the user functionality that allows to run workflows on schedule (by configuring a cron pattern) | 09:59 |
| rakhmerov | another is Scheduler, which is an internal component, critical for all stable work of Mistral Engine | 10:00 |
| rakhmerov | it's not visible from outside but yes, it's probably the worst bottleneck for scaling out that we currently have | 10:00 |
| rakhmerov | I'm starting to rework it actually so that it becomes more scalable | 10:01 |
| pgaxatte | can the scheduler be scaled out? | 10:01 |
| pgaxatte | i saw there is an option to use zookeeper, is this related? | 10:01 |

| *** AlexeyAbashkin has quit IRC | 10:11 | |
| *** d0ugal has quit IRC | 10:17 | |
| rakhmerov | pgaxatte: that's the point that it doesn't scale well | 10:18 |
| rakhmerov | zookeeper no, not planned | 10:18 |
| rakhmerov | pgaxatte: so, we have Mistral stable installations with 6-7 engines | 10:19 |
| rakhmerov | under high load | 10:20 |
| rakhmerov | if we add more we start getting lots of troubles | 10:20 |
| rakhmerov | if the load is not so high then you can have 10+ engines with some configuration tweaks | 10:20 |
| rakhmerov | speaking about executors, they scale well, you can add as many as you need | 10:21 |
| lxkong | pgaxatte: hi, yes, i've only tested mistral in single region, and invoke services that belong to multi-regions. But it's a loooong time ago. Since mistral is temporarily not in our roadmap, i stopped working on that | 10:30 |
| *** d0ugal has joined #openstack-mistral | 10:37 | |
| apetrich | I didn't know that CERN used mistral.. http://openstack-in-production.blogspot.com/2018/03/expiry-of-vms-in-cern-cloud.html | 10:56 |
| lxkong | do you guys has the use case that use mistral to trigger k8s jobs? | 10:58 |
| *** AlexeyAbashkin has joined #openstack-mistral | 11:05 | |
| pgaxatte | rakhmerov: alright, that's very good to know | 11:57 |
| pgaxatte | lxkong: thanks for your feedback | 11:58 |
| pgaxatte | apetrich: it seems they use it for internal administration so i'm not sure they provide the access to mistral to their users | 12:00 |
| apetrich | pgaxatte, looking at their workflows it seems so https://gitlab.cern.ch/cloud-infrastructure/mistral-workflows | 12:01 |
| pgaxatte | rakhmerov: about zookeeper, i saw a bit of documentation mentionning it (https://docs.openstack.org/mistral/ocata/developer/webapi/v2.html), what is it used for? | 12:06 |

| toure | d0ugal ping | 13:11 |
| toure | d0ugal I was curious to see if you managed to create a spec file for mistral-extra I have and running into odd macro issues | 13:12 |
| toure | but the errors are useless | 13:12 |
| d0ugal | toure: nope, I never got a moment to try. Maybe copy the mistral-lib one? should be almost the same | 13:15 |
| d0ugal | or ask for help in #rdo? | 13:15 |
| toure | yeah I have modeled my spec from mistral-lib, will ask #rdo, was just curious | 13:16 |
| d0ugal | toure: what are the errors? | 13:20 |
| toure | ok, that is odd, rpmlint stopped giving me the error | 13:22 |
| toure | this was late last night, maybe the rpm ninjas fixed something while I was sleeping :) | 13:23 |

| toure | or will 7.0.01 release soon | 13:44 |
| toure | sorry 7.0.0 | 13:45 |
