Empowering Teammates to Dynamically Set Azure Subscriptions in Azure DevOps Pipelines

Dheeman 

1. If you do not have one already, create an AzureRM Service Connection in Azure DevOps.  Grant the Service Principal the appropriate role in each subscription that you want it to read from (likely reader would be sufficient).  Copy the Service Connection's ID to the clipboard.
2. In your pipeline, add this new powershell task.  This will "target" the Service Connection to the subscriptionId that was passed in.

- pwsh: Write-Host "##vso[task.setendpoint id={YOUR SERVICE CONNECTION ID HERE};field=dataParameter;key=subscriptionId]${{ parameters.SubscriptionId }}"
  displayName: Set Subscription

3. Then change the task type for your script that you wrote.  Use the Azure CLI task with powershell and use this Service Connection that you created.  Now it should authenticate to the subscription you passed in and execute your script in that context.  It will not matter what you logged into last on your local machine.
