title: Terraform Azure Provision VM to existing subnet/vnet/resourcegroup
body: <p>I have an existing Azure environment with resource groups, networks, vnets and subnets already created. I want to use terraform to automate the deployment of VMs into this existing Azure environment, but all the examples and documentation are oriented towards building entire nevironments/infrastructure from scratch.</p>
  
  <p>Can anyone suggest documentation or examples on how to approach deploying a VM to an existing Azure environment using terraform?</p>
