Create a virtual machine using an existing managed OS disk with CLI
This script creates a virtual machine by attaching an existing managed disk as OS disk. Use this script in preceding scenarios:
- Create a VM from an existing managed OS disk that was copied from a managed disk in different subscription
- Create a VM from an existing managed disk that was created from a specialized VHD file
- Create a VM from an existing managed OS disk that was created from a snapshot
To run this sample, install the latest version of the Azure CLI. To start, run
az login to create a connection with Azure.
Samples for the Azure CLI are written for the
bash shell. To run this sample in Windows PowerShell or Command Prompt, you may need to change
elements of the script.

Clean up deployment
Run the following command to remove the resource group, VM, and all related resources.
az group delete --name myResourceGroup
This script uses the following commands to get managed disk properties, attach a managed disk to a new VM and create a VM. Each item in the table links to command specific documentation.
|az disk show||Gets managed disk properties using disk name and resource group name. Id property is used to attach a managed disk to a new VM|
|az vm create||Creates a VM using a managed OS disk|
