How to parameterize the values in ARM templates from Dev ADF while moving it to PROD ADF.

Question

I have generated ARM template using CICD pipeline for Dev ADF. I'm trying to parametrize the values and deploy to Prod. I am unable to change the secretname under azure keyvault in prod linked service. Can someone help on this?

Whereas I'm able to change the values of the below from the parameter file:

Note : I'm using the ARMTemplateParametersForFactory.json file and created a prod parameter file. I'm unable to see Secret name in ARM template. I tried adding as per the documentation which didn't help:

Hello Vineeth Kalangi,

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

I understand that you are having issues to parameterize your linked services with Azure Data Factory (ADF) and secret name for Azure Key Vault.

When creating a linked service in ADF that connects to an Azure Key Vault, you can specify the secret name, and this secret name will correspond to the secret you want to retrieve from the Key Vault. So, since you're able to change other values from the parameter file, but not the secret name you will have to do the followings in resolving this issue. In your ARM template, the secret name should be specified within the properties section of the linked service definition:

{
        "type": "Microsoft.DataFactory/factories/linkedservices",
        "apiVersion": "2018-06-01",
        "name": "[concat(parameters('factoryName'), '/AzureKeyVaultLinkedService')]",
        "properties": {
            "type": "AzureKeyVault",
            "typeProperties": {
                "baseUrl": "https://your-keyvault-name.vault.azure.net/",
                "authenticationType": "ManagedServiceIdentity",
                "secretName": "your-secret-name"  // Specify your actual secret name here
            }
        }
    }
