How to parameterize the scope property or the subscription name in the event trigger in ADF between different environments. I want to dynamically use the subscription name between the different environments.

Hello Ganapathy, Muthu Mari (Cognizant),

Welcome to the Microsoft Q&A and thank you for posting your questions here.

I understand that you would like to parameterize the scope property or the subscription name in the event trigger in Azure Data Factory (ADF) to dynamically use the subscription name between different environments.

The below steps are a detailed step-by-step guide:

1. Define parameter files for each environment (e.g., dev-parameters.json, test-parameters.json, prod-parameters.json). For an example dev-parameters.json:

     {
       "subscriptionName": {
         "value": "dev-subscription-id"
       }
     }

2. In your ARM template, define parameters for the scope property or subscription name similar to the below snippet:

   {
     "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
     "contentVersion": "1.0.0.0",
     "parameters": {
       "subscriptionName": {
         "type": "string"
       }
     },
     "resources": [
       {
         "type": "Microsoft.DataFactory/factories/triggers",
         "apiVersion": "2018-06-01",
         "name": "[concat(parameters('factoryName'), '/triggerName')]",
         "properties": {
           "type": "BlobTrigger",
           "typeProperties": {
             "scope": "[concat('/subscriptions/', parameters('subscriptionName'), '/resourceGroups/resourceGroupName/providers/Microsoft.Storage/storageAccounts/storageAccountName')]"
           }
         }
       }
     ]
   }

3. When deploying your ADF resources, use your CI/CD pipeline (e.g., Azure DevOps, GitHub Actions) to inject the appropriate parameter file based on the target environment. For an example of Azure DevOps pipeline YAML:

   parameters:
     - name: environment
       displayName: Select Environment
       type: string
       default: dev
       values:
         - dev
         - test
         - prod
   jobs:
     - job: DeployADF
       steps:
         - task: AzureResourceManagerTemplateDeployment@3
           inputs:
             deploymentScope: 'Resource Group'
             azureResourceManagerConnection: 'AzureRMConnection'
             subscriptionId: '$(subscriptionId)'
             action: 'Create Or Update Resource Group'
             resourceGroupName: '$(resourceGroupName)'
             location: '$(location)'
             templateLocation: 'Linked artifact'
             csmFile: '$(System.DefaultWorkingDirectory)/templates/azuredeploy.json'
             csmParametersFile: '$(System.DefaultWorkingDirectory)/parameters/$(environment)-parameters.json'
