Get PrincipalId when deploying ARM Template

Question

Is it possible to retrieve the ID of the user that is deploying the ARM template?

There is the subscription() function that retrieves information about the subscription the template is being deployed to, including the subscription ID, I'm hoping there is something similar for the principal.

Answer 1

No, this is not possible as of today (26.06.2017). This might change in the future. You can always create feedback item for that and track it.

Answer 2

This is now possible using reference().

"[reference(resourceId('Microsoft.Web/sites', variables('appService')), '2016-08-01', 'Full').identity.principalId]"

Note the use of 'full' parameter in the reference() function.
