Get a list of Azure OS Disks attached to VMs in specific subscription

Question

I am fetching a list of OS Disks attached to VMs in Azure in all resource groups of specific subscription. I found a AZ utility to fetch the list in json format.

Using below sequence I am able to get the list in json format, Is there any similar way to get this achieved using any python module ?

az login
az account set --subscription <subscription>
az disk list

Yes, it is possible. You could use method list to get disks in your subscription.

For example:

from azure.common.credentials import ServicePrincipalCredentials
from azure.mgmt.compute import ComputeManagementClient
from azure.mgmt.resource import ResourceManagementClient, SubscriptionClient

# Tenant ID for your Azure Subscription
TENANT_ID = ''

# Your Service Principal App ID
CLIENT = ''

# Your Service Principal Password
KEY = ''

credentials = ServicePrincipalCredentials(
    client_id = CLIENT,
    secret = KEY,
    tenant = TENANT_ID
)

subscription_id = ''

compute_client = ComputeManagementClient(credentials, subscription_id)

disks = compute_client.disks.list()
for disk in disks:
    print disk

Note: It will return all disks in your subscription. But it is possible some disks are not OS disk, they maybe Data disk or a disk that not attach for a VM.
