    Hi Madhu Ram,

    Thanks for reaching out to Microsoft Q&A.

    Implement a configuration that is dynamically adjusted based on the target environment when creating a pull request. This approach typically involves using parameter files for each environment (such as dev-parameter.json, test-parameter.json, and prod-parameter.json) and Azure DevOps pipelines or similar CI/CD tools to deploy to the right environment.

    Create Parameter Files for Each Environment: parameter.json

    {
      "linkedService:AzureBlobStorage": {
        "properties": {
          "typeProperties": {
            "connectionString": "DefaultEndpointsProtocol=https;AccountName=devstorage;AccountKey=XXXXXX;"
          }
        }
      },
      "trigger:DailyTrigger": {
        "properties": {
          "typeProperties": {
            "recurrence": {
              "frequency": "Day",
              "interval": 1,
              "startTime": "2024-10-01T00:00:00Z"
            }
          }
        }
      }
    }
    
    
    

    Add Parameters to Linked Services and Triggers

    When defining linked services and triggers in ADF, include parameters that will reference environment-specific values.

    • In Linked Services, you can parameterize fields like connection strings, database names, etc.
    • In Triggers, you can parameterize properties such as recurrence intervals, start times, etc.

    Example Linked Service with Parameters::

    {
      "name": "AzureBlobStorage",
      "properties": {
        "type": "AzureBlobStorage",
        "typeProperties": {
          "connectionString": {
            "value": "@{linkedService().connectionString}",
            "type": "SecureString"
          }
        }
      }
    }
    
    
    

    Use Parameter Files in CI/CD Pipeline

    When creating a pull request or triggering a deployment to a specific environment, use your CI/CD pipeline (Azure DevOps, GitHub Actions, etc.) to inject the parameter file (parameters.json) based on the target environment.

    Here’s how to implement this in Azure DevOps Pipeline:

    • Define the environment variable in the pipeline:
        parameters:
          - name: environment
            displayName: Select Environment
            type: string
            default: dev
            values:
              - dev
              - test
              - prod
      
    • Use the environment parameter to select the correct parameter file:
        steps:
        - task: AzureDataFactoryV2@1
          inputs:
            azureSubscription: 'Azure_Subscription_Name'
            ResourceGroupName: 'Your_Resource_Group'
            DataFactoryName: 'Your_Data_Factory_Name'
            Stage: 'armTemplateDeployment'
            TemplateLocation: 'LinkedArtifact'
            csmFile: 'ARMTemplate/ADF_Template.json'
            csmParametersFile: '$(Pipeline.Workspace)/arm-templates/$(parameters.environment)-parameters.json'
            deploymentMode: 'Incremental'
        
        
      
      This pipeline will dynamically pick the appropriate parameter file (dev-parameters.json, prod-parameters.json, etc.) based on the selected environment.
    • Automate the Parameter Injection in the Deployment Process To fully automate this process, your pull request workflow should integrate the CI/CD process. You can configure it to automatically deploy to different environments when a PR is merged, using the correct parameter file for that environment.
