in_azure_vm {AzureVMmetadata}

Check if R is running in an Azure VM

Description

Check if R is running in an Azure VM

Usage

in_azure_vm()

get_vm_cert(nonce = NULL)

Arguments

nonce

An optional string to use as a nonce.

Details

These functions check if R is running in an Azure VM by attempting to contact the instance metadata host. in_azure_vm simply returns TRUE or FALSE based on whether it succeeds. get_vm_cert provides a stronger check, by retrieving the VM's certificate and throwing an error if this is not found. Note that you should still verify the certificate's authenticity before relying on it.

Value

For in_azure_vm, a boolean. For get_vm_cert, a PKCS-7 certificate object.
