Identity document

Written by

Updated at March 7, 2025

When you create a VM, an identity document that stores information about the VM is generated. It contains the IDs of the VM, Marketplace product, disk image, etc. VMs can request information about themselves from the metadata service.

For more information on how to get an identity document, see Getting a VM instance identity document.

Signed identity documentsSigned identity documents

If intending to use the contents of an identity document for critical tasks, you should check its contents and confirm its authenticity prior to using it.

Apart from identity documents, the VM metadata service provides their cryptographic signatures. You can use these signatures to verify the document's origin, authenticity, and integrity.

For more information on how to check the contents of the identity document and validate it, see Checking identity document signature.
