Azure Automation: Runbook: does it know it's TenantID?

Question

Good afternoon

I guess that this is relation is true:

Azure Tenant
» Azure Subscription
  » Azure Automation
    » Runbook

Therefore I have this question:

Is there a PowerShell command which can be used to get the TenantID in which the Runbook is running?

Answer 1

If you want to run the command inside of the runbook, you could use this:

$servicePrincipalConnection = Get-AutomationConnection -Name "AzureRunAsConnection"        
Write-Output $servicePrincipalConnection.TenantId

Note: there is a prerequisite, when you create the automation account, you need to select Create Azure Run As account with Yes, otherwise the AzureRunAsConnection is not existing.
