| tej | Hi. I would like to be able to schedule a workflow to run at a specific time from another workflow. I see in the dsl v1 spec there's a trigger entity, but i don't see that in v2. Essentially what i what is a cron trigger, but i don't see how to do that within a workflow. | 14:23 |
| akuznetsova | tej, hi | 14:42 |
| tej | hi | 14:42 |
| *** bradjones has joined #openstack-mistral | 14:42 | |
| *** bradjones has quit IRC | 14:42 | |
| *** bradjones has joined #openstack-mistral | 14:42 | |
| akuznetsova | tej, yes, in DSL v2 we have cron-triggers which allows to run specific workflow by cron-pattern | 14:45 |
| tej | akuznetsova, cool, do you have an example? | 14:45 |
| akuznetsova | if your 'specific' time isn't very big, that in one wf you can create task that will run another workflow with some delay | 14:46 |
| tej | or the spec? | 14:46 |
| tej | Right, the day would be on the order of days | 14:47 |
| tej | so it seemed a cron trigger was better | 14:47 |
| akuznetsova | tej, cron trigger is a separate object, that can be created via CLI, it is not a part of wf http://docs.openstack.org/developer/mistral/guides/mistralclient_guide.html#cron-triggers | 14:49 |
| akuznetsova | http://docs.openstack.org/developer/mistral/overview.html#tasks-scheduling-cloud-cron | 14:50 |
| tej | Yeah, i have that working just fine, i was interested in creating that cron trigger via a workflow. It doesn't look like there are mistral actions to call the cli (like the other openstack components) | 14:52 |
| tej | So i thought there was some other mechanism | 14:52 |
| akuznetsova | tej, no, now we can't call cron-trigger from wf | 14:56 |
| tej | Here's what i want to do: Run a wf that takes the number of days to delay. That workflow would then start 2 other workflows one to run at number of days -2 and one run at number of days. | 14:58 |
| *** sergmelikyan has joined #openstack-mistral | 14:59 | |
| tej | So it looks like what i could do is use the task delays or write a custom action that would create cron triggers | 14:59 |
| tej | via the cli | 14:59 |
| tej | does that sound like the right approach? | 14:59 |
| akuznetsova | tej, yes, I guess that you can create custom action that will create smth similar to cron-trigger | 15:01 |
| tej | akuznetsova, thanks! I can try that. Just follow the creating custom action guide in the docs? | 15:02 |
| akuznetsova | tej, yes, here is a short guide how to create and activate custom action http://docs.openstack.org/developer/mistral/developer/creating_custom_action.html | 15:03 |
| tej | akuznetsova, thanks! | 15:04 |
| rakhmerov | tej: hi | 15:13 |
| rakhmerov | just a couple of clafifications | 15:13 |
| rakhmerov | yes, you cannot create a trigger in a workflow | 15:14 |
| tej | rakhmerov, hi | 15:14 |
| rakhmerov | there was a strong reason why we removed triggers from DSL | 15:14 |
| rakhmerov | primarily because we couldn't have any specific data (including secure stuff) configured right in DSL | 15:14 |
| rakhmerov | e.g. input of workflow that a trigger should start | 15:15 |
| rakhmerov | so here's what you could do: | 15:15 |
| rakhmerov | 1) you can easily create a custom action (just a Python class) that would create cron trigger via Mistral API | 15:16 |
| rakhmerov | should be pretty straightforward to do | 15:16 |
| rakhmerov | so that you could create a task in wf like: | 15:16 |
| rakhmerov | my_task: | 15:16 |
| rakhmerov | action: std.create_cron_trigger name=... | 15:17 |
| rakhmerov | 2) You can try to use policies "wait-before" or "wait-after" that make delays before or after task | 15:17 |
| rakhmerov | it's configured in seconds and it could be an expression | 15:18 |
| rakhmerov | YAQL expression | 15:18 |
| tej | Is one way better than another? The custom action looked pretty easy | 15:18 |
| rakhmerov | custom action looks an interesting solution to me | 15:19 |
| tej | yeah | 15:19 |
| rakhmerov | more flexible | 15:19 |
| tej | right | 15:19 |
| tej | just curious is there a reason you don't expose the mistral cli as actions (like the other openstack components)? | 15:20 |
| rakhmerov | the only issue with it that I see now is that you'll need to call Mistral API (either directly or via Python Library) and you need to configure connectivity correctly | 15:20 |
| rakhmerov | could you elaborate a little bit? What do you mean by actions? | 15:21 |
| rakhmerov | sorry, I may not be to familiar with how it's done in other projects | 15:21 |
| tej | For example, i can run action: nova.server_list | 15:21 |
| rakhmerov | yes | 15:21 |
| tej | i was hoping i could just do mistral.cron-trigger-create.... | 15:22 |
| tej | action: mistral.cron-trigger-create... (i mean) | 15:22 |
| *** sergmelikyan has quit IRC | 15:22 | |
| tej | I can try the custom action though. | 15:24 |
| openstackgerrit | Merged openstack/mistral-extra: Adding new example - upgrade ubuntu VM kernel https://review.openstack.org/236892 | 15:25 |
| rakhmerov | tej: it could be actually awesome | 15:26 |
| rakhmerov | never thought about it seriously | 15:26 |
| openstackgerrit | Merged openstack/mistral-extra: Adding new example - crawl data from VMs https://review.openstack.org/236896 | 15:26 |
| rakhmerov | this action pack could contain things like: mistral.create-workflow, mistral.create-trigger etc. etc. | 15:26 |
| rakhmerov | actions to manage Mistral stuff itself | 15:27 |
| tej | yeah, exactly | 15:27 |
| tej | that would be cool, i think | 15:27 |
| rakhmerov | hm... I'll write it down, we need to discuss it with the team | 15:27 |
| rakhmerov | yeah, very cool ) | 15:27 |
| tej | Sounds good! Are you planning to be at the summit? | 15:27 |
| rakhmerov | it just never came to my mind :) | 15:27 |
| rakhmerov | yes, I will be there | 15:27 |
| rakhmerov | btw, we have 4 sessions | 15:27 |
| rakhmerov | so please join | 15:27 |
| rakhmerov | http://mitakadesignsummit.sched.org/type/Mistral#.ViZdhdbOyEk | 15:28 |
| tej | I would love to, but unfortunately i can't be there. I will have a co-worker of mine try to meet up with you at some point to discuss some things we are thinking about. | 15:30 |
| tej | thanks again for all your help! | 15:30 |
| rakhmerov | you're welcome ) | 15:30 |
