Description

Just like, for examle, the azurerm_windows_web_app, it would be nice if the azurerm_container_app resources and data sources exposed the identity block where we can access the principal_id.

New or Affected Resource(s)/Data Source(s)

azurerm_container_app

Potential Terraform Configuration

resource "azurerm_container_app" "example" {
 // etcetera
}

resource "azurerm_role_assignment" {
  scope = (Azure Container Registry resourceId)
  role_definition_name = "Contributor"
  principal_id = azurerm_container_app.example.identity.principal_id
}

This workaround worked for me: object_id = azurerm_container_app.my_app_name.identity.0.principal_id
