parameterization of user assigned managed identity

Question

I have a user assigned managed identity and it is associated with my data factory.
This works fine in our DEV environment.

When it comes to deployment however, there is no parameter to provide the user assigned managed Identity that is used in our PRD environment.
As ADF creates the ARM templates itself, it seems my only options are:

• publish the ADF templates to adf_publish branch.
• Manually checkout the arm templates and alter the managed identity
• manually trigger deployment.

or

• use the same managed identity in DEV and PRD

Neither option is desirable.
Is there a way to parameterize the user assigned managed identity for a data factory?

Below is the json from the arm template ADF generates. Note the user assigned Managed Identity is hard coded and not parameterized.

 "name": "[concat(parameters('factoryName'), '/KV_Access_MI')]",  
 "type": "Microsoft.DataFactory/factories/credentials",  
 "apiVersion": "2018-06-01",  
 "properties": {  
 "type": "ManagedIdentity",  
 "typeProperties": {  
 "resourceId": "/subscriptions/xxxxx-xxxxx-xxxxx-xxxxx-xxxxx/resourcegroups/DEV-RG/providers/Microsoft.ManagedIdentity/userAssignedIdentities/dev-ManagedIdentity"  
 }  
 },  
 "dependsOn": []  

Answer 1

This appears to work, until I add a try to link to a shared Integration runtime.
The user assigned managed identity has access to the shared integration runtime.

When i run the deployment, it fails saying the data factory does not have access to the shared integration runtime.
This tells me that the ARM template interperter is trying to create the integration runtime link before adding the user assigned Managed Identity.
I cannot find a way to alter the order of execution in the ARM as its generated by ADF and I cant manually edit it.

Any ideas?

Answer 2

Ahh, I made a typo somewhere @na .

To parameterize the credentials, add into the ARM Template configuration:

    "Microsoft.DataFactory/factories/credentials" : {  
        "properties": {  
            "typeProperties": {  
                "resourceId": "="  
            }  
        }  
    }  

I found the answer in the verry bottom of the sample customization template.

Hope this will help. Please let us know if any further queries.
