ARM Template to create schedule trigger in ADF

Question

I am creating a basic ARM Template in ADF V2 to create triggers , I am new to ARM templates and slowly adding stuff to my template
below , my pipeline input source is on Prem SQL tables which I am pulling through dataset and linked Service what do I put in parameters for input path below code, my out is ADLS Gen 2

{
"properties": {
"name": "MyTrigger",
"type": "ScheduleTrigger",
"typeProperties": {
"recurrence": {
"frequency": "Hours",
"interval": 24,
"startTime": "2020-12-18T17:15:00Z",
"endTime": "2020-12-18T18:17:00Z",
"timeZone": "UTC"
}
},
"pipelines": [{
"pipelineReference": {
"type": "PipelineReference",
"referenceName": "MCF_PipeLine_Segment"
},
"parameters": {
"inputPath": "LS_MCFMemberAccess",
"outputPath": "@markus.bohland@hotmail.de ('MCF(Segments)/',formatDateTime(utcnow(), 'yyyy'),'/',formatDateTime(utcnow(), 'MM'))"
}
}
]
}
}

Hello @AzeemK ,

Thanks for the ask and also for using the Microsoft Q&A forum.

what do I put in parameters for input path below code?

You can add a parameter to your pipeline and then you can edit the JSON file of your trigger.

For more details, refer How to pass parameters to an ADF pipeline from Schedule type trigger?.

OR

The pipeline takes two parameters values: inputPath and outputPath. And you pass values for these parameters from the trigger.

{  
    "properties": {  
        "name": "MyTrigger",  
        "type": "ScheduleTrigger",  
        "typeProperties": {  
            "recurrence": {  
                "frequency": "Minute",  
                "interval": 15,  
              "startTime": "2020-12-18T17:15:00Z",  
             "endTime": "2020-12-18T18:17:00Z",  
                "timeZone": "UTC"  
            }  
        },  
        "pipelines": [{  
                "pipelineReference": {  
                    "type": "PipelineReference",  
                    "referenceName": "Adfv2QuickStartPipeline"  
                },  
                "parameters": {  
                    "inputPath": "adftutorial/input",  
                    "outputPath": "adftutorial/output"  
                }  
            }  
        ]  
    }  
}

Hi @AzeemK ,

Thank you for asking this question. Probably you know all of this but wanted to clarify few things:

First: when you add a new Trigger (create), you only need to provide trigger related information e.g., trigger type, when the trigger will start running, how frequent the trigger will run.

Now after creating a trigger, you can associate one or multiple pipelines to that trigger. That means when the trigger will run, it will fire/execute the associate pipelines attached to it.

Now when you add trigger to any pipeline, at that time you have to provide pipeline parameters information. You do not have to pass the linked service information (because that information are already mentioned in the Dataset) only the values for the pipleine parameters (if you have any). From the screenshot you provided, I see that in pipeline "MCF_PipeLine_Segmen", you are passing two parameters inputPath, OutputPath. You can pass string values along with other type and also you can pass expression like you did for "outputPath": "@markus.bohland@hotmail.de ('MCF(Segments)/',formatDateTime(utcnow(), 'yyyy'),'/',formatDateTime(utcnow(), 'MM'))".

Lastly: for the ARM template, ADF take care of the ARM template. When you publish your changes, ARM template for the DataFactory automatically get created/updated. You can download the ARMTemplate from the top icon ARM template --> Export ARM template.

Hope this helps. If it does, please don't forget to "accept the answer" and "up-vote"! Thank you!

I have created a new trigger why is this not showing up in my TRIGGER RUNS under schedule , it does show up in Pipeline runs , I want o schedule it not run manually every time see screen shots below it should show up in second screen shot under trigger runs
also can I export trigger as ARM template so I can modify it for different pipelines and import it back
