Metadata for an Azure VM

instance

attested

events

update_instance_metadata()

update_attested_metadata(nonce = NULL)

update_scheduled_events()

nonce

For update_attested_metadata, an optional string to use as a nonce.

instance, attested and events are environments.

The instance, attested and events environments contain the instance metadata, attested metadata, and scheduled events respectively for a VM running in Azure. instance and attested are automatically populated when you load the AzureVMmetadata package, or you can manually populate them yourself with the update_instance_metadata and update_attested_metadata functions. events is not populated at package startup, because calling the scheduled event service can require up to several minutes if it is not running already. You can manually populate it with the update_scheduled_events function.

If AzureVMmetadata is loaded in an R session that is not running in an Azure VM, all the metadata environments will be empty.

The updating functions return the contents of their respective environments as lists, invisibly.
