Scheduler job in Firefly / Runtime

[eldhov19157560]

Hi Team,

We would like to use a scheduler job in firefly app, we found the following option https://github.com/apache/openwhisk-package-alarms is there any alternate option in firefly?

Hi @eldhov19157560,

Yes the alarm package is available.

You can read more about it here https://github.com/AdobeDocs/adobeio-runtime/blob/33d0979a45b9e35e8addaad7e97dfb00f8ea5e12/reference...

The documentation shows an example for directly using the cli to set up triggers, but you can easily define the trigger through the manifest file. Here's an example manifest file for that. 

Manifest File Example: “Hello world” Action with a compatible Trigger and Rule

package:
  name: hello_world_package
  version: 1.0
  license: Apache-2.0
  actions:
    hello_world_triggerrule:
      function: src/hello_plus.js
      runtime: nodejs
      inputs:
        name: string
        place: string
        children: integer
        height: float
      outputs:
        greeting: string
        details: string

  triggers:
    meetPerson:
      inputs:
        name: Sam
        place: the Shire
        children: 13
        height: 1.2

  rules:
    meetPersonRule:
      trigger: meetPerson
      action: hello_world_triggerrule

Hi @SarahXu how would my trigger look like if I want to have it triggered daily as a cron job?

[Urs_Boller]

@SarahXu can I use the "Triggers" in the manifest file to create the scedule? and how would the structure look like?

[SarahXu]

comment makes it a bit difficult to lay out code but it should look something like this ``` triggers: \ sample-trigger: \ feed: /whisk.system/alarms/alarm \ cron: "0 * * * *

comment makes it a bit difficult to lay out code but it should look something like this

triggers: 
    sample-trigger:
       feed: /whisk.system/alarms/alarm
       cron: 0 * * * * 
       trigger_payload: {"name":"Vlad","place":"Transylvania"}
       startDate: xxxx
       stopDate: xxxx

you can see https://github.com/AdobeDocs/adobeio-runtime/blob/33d0979a45b9e35e8addaad7e97dfb00f8ea5e12/reference... for some more example on the rules you can use for the alarm package

Thanks @Urs_Boller and @SarahXu for the support

@SarahXu thanks a lot for all the support

@SarahXu I don't think the provided pattern works, at least I received errors when using the code in my manifest.yml file.

After some testing I think the pattern using openWhisk alarms should be something like this:

...
triggers:
  myCustomTriggerName:
    feed: /whisk.system/alarms/alarm
    inputs: 
      cron: '* * * * *'
      start-date: ''2020-08-30T13:37:00.00Z'
      stop-date: '2020-08-30T12:50:00.000Z'
...

 could you please check what the right pattern is to use in the manifest.yml file? thanks

[SarahXu]

You are correct! Thank you -- sorry for missing the `input` block before the params.

based on the idea from @SarahXu I found this blog post and it exactly describes the steps to make within the app: https://medium.com/openwhisk/whisk-deploy-alarm-trigger-6c0984b06745
