Suppose I have a Virtual Machine provisioned in Azure running Windows Server 2016 standard Azure image.

Without installing anything onto the VM, how can I retrieve the details of the current VM using PowerShell from inside the VM?

Some properties I would like to retrieve are:

  • VM name
  • VM IP address
  • Subscription ID
  • VM location

I believe this is possible because the Windows Desktop image in Azure automatically shows most of the above information. So how can I get this information programmatically through PowerShell?

(As usual, Microsoft documentation live up to their reputation of no value)

Any help would be greatly appreciated.

I suggest you to use either Azure Instance Metadata Service

Invoke-RestMethod -Headers @{"Metadata"="true"} -Method GET -NoProxy -Uri http://169.254.169.254/metadata/instance?api-version=2020-09-01 | ConvertTo-Json
