How to delete a disk with azure-sdk-for-python?

Question

I'm using azure-sdk-for-python to create and delete VMs.

https://github.com/Azure/azure-sdk-for-python

http://azure-sdk-for-python.readthedocs.io/en/latest/

I've successfully managed to write the code to create and delete my VMs using the resource manager approach (not the classic).

The basic to create a VM can be seen here: http://azure-sdk-for-python.readthedocs.io/en/latest/resourcemanagementcomputenetwork.html

I'm not worried about deleting the resource group and the storage account, as I'm using the same for all my VMs.

To delete a the created VM I have something like this:

# 1. Delete the virtual machine
result = compute_client.virtual_machines.delete(
    group_name,
    vm_name            
)
result.wait()
# 2. Delete the network interface
result = network_client.network_interfaces.delete(
    group_name,
    network_interface_name
)
result.wait()
# 3. Delete the ip
result = network_client.public_ip_addresses.delete(
    group_name,
    public_ip_address_name
)
result.wait()

As some know the data disks are not deleted along with its VM. I know it can be done with the Azure CLI: https://azure.microsoft.com/en-us/documentation/articles/storage-azure-cli/

azure storage blob delete -a <storage_account_name> -k <storage_account_key> -q vhds <data_disk>.vhd

But I don't know how to do it programmatically with azure-sdk-for-python. And I didn't want to depend on the Azure CLI as the rest of my code is using the python sdk.

I would appreciate some help on how to do it.

Thanks

You can leverage the Azure ComputeManagementClient's disks APIs to obtain list of disks associated with a VM and then iterate over them to delete the disks. Here's some sample code to achieve the same:

def delete_vm(self, vm_name, nic_name, group_name):
    # Delete VM
    print('Delete VM {}'.format(vm_name))
    try:
        async_vm_delete = self.compute_client.virtual_machines.delete(group_name, vm_name)
        async_vm_delete.wait()
        net_del_poller = self.network_client.network_interfaces.delete(group_name, nic_name)
        net_del_poller.wait()
        disks_list = self.compute_client.disks.list_by_resource_group(group_name)
        disk_handle_list = []
        for disk in disks_list:
            if vm_name in disk.name:
                async_disk_delete = self.compute_client.disks.delete(self.group_name, disk.name)
                async_disk_handle_list.append(async_disk_delete)
        print("Queued disks will be deleted now...")
        for async_disk_delete in disk_handle_list:
                async_disk_delete.wait()
    except CloudError:
        print('A VM delete operation failed: {}'.format(traceback.format_exc()))
        return False
    print("Deleted VM {}".format(vm_name))
    return True
