07 - Extending with Triggers (Dedicated)¶

Add Timer, Queue, and Blob triggers to your Dedicated (App Service Plan) PowerShell app. PowerShell uses the classic function.json binding model.

Timer Trigger¶

TimerExample/function.json:

{
  "bindings": [
    {
      "name": "Timer",
      "type": "timerTrigger",
      "direction": "in",
      "schedule": "0 */5 * * * *"
    }
  ]
}

TimerExample/run.ps1:

param($Timer)
Write-Information "Timer fired at $(Get-Date -Format o)"

Queue Trigger¶

QueueExample/function.json:

{
  "bindings": [
    {
      "name": "QueueItem",
      "type": "queueTrigger",
      "direction": "in",
      "queueName": "work-items",
      "connection": "AzureWebJobsStorage"
    }
  ]
}

param($QueueItem, $TriggerMetadata)
Write-Information "Dequeued: $QueueItem"

Blob Trigger¶

BlobExample/function.json:

{
  "bindings": [
    {
      "name": "InputBlob",
      "type": "blobTrigger",
      "direction": "in",
      "path": "uploads/{name}",
      "connection": "AzureWebJobsStorage"
    }
  ]
}

param($InputBlob, $TriggerMetadata)
Write-Information "Blob $($TriggerMetadata.name) is $($InputBlob.Length) bytes"

Verification¶

Deploy, then drop a message on the work-items queue or upload a blob to uploads/. Confirm the invocation appears in az functionapp log tail.
