I am having RDP access issues when trying to create a spot instance on azure through azure api for python

Question

I am trying to create a spot instance on azure from azure API through python code. The following code successfully creates the spot instance machine on Azure but when I try to connect through RDP, the credentials given in the API does not work.

def create_spot_instance(self):
        current_timestamp = round(datetime.timestamp(datetime.now()))

        vm_name = f"spot-{current_timestamp}"

        vm_username = AZURE_RDP_USERNAME
        vm_password = secrets.token_urlsafe(13)
        vm_location = AZURE_LOCATION
        vm_image_id = self.get_image_id(AZURE_RESOURCE_GROUP, AZURE_CAPTURE_IMAGE)
        new_nic = self.creating_nic_and_ip_from_existing_vm(vm_name, vm_location)

        vm_params = VirtualMachine(
            location=vm_location,

                )
            ),
            os_profile=OSProfile(
                computer_name=vm_name,
                admin_username='hello',
                admin_password='hello_123'
            ),
            network_profile=NetworkProfile(
                network_interfaces=[
                    NetworkInterfaceReference(id=new_nic.id)

            billing_profile=BillingProfile(max_price=config.AZURE_MAX_SPOT_INSTANCE_BUDGET)
        )

        try:
            self.service.virtual_machines.begin_create_or_update(AZURE_RESOURCE_GROUP, vm_name, vm_params)
            return VMInstance.objects.create(
                instance=vm_name, project=AZURE_RESOURCE_GROUP, provider='AZURE', status=False,
                script_run_on_start=False, username=vm_username, password=vm_password)
        except Exception as ex:
            return

The username 'hello' and the password 'hello_123' does not work for the RDP access when the spot instance is created. I have to then manually reset the password in order to make it work

I tried the code above and copied this from the official Azure docs

Answer 1

The username 'hello' and the password 'hello_123' does not work for the RDP access when the spot instance is created. I have to then manually reset the password in order to make it work

By default hello_123 is not supported as a password due to username and password limitations while deploying Azure VM, I tried creating a Spot VM with hello_123 password and the password was not selected due to the naming conventions and a Warning - The value must be between 12 and 123 characters long, Refer below:-

I tried creating a Spot VM with Python SDK by following the username and password naming conventions as mentioned in this Document:-

Username- FAQ about Windows VMs in Azure - Azure Virtual Machines | Microsoft Learn

Password- FAQ about Windows VMs in Azure - Azure Virtual Machines | Microsoft Learn

My Python code to Deploy a SpotVM:-

# from azure.common.credentials import ServicePrincipalCredentials

from  azure.identity  import  DefaultAzureCredential

from  azure.mgmt.compute.v2019_07_01  import  ComputeManagementClient

from  azure.mgmt.compute.v2019_07_01.models  import  VirtualMachinePriorityTypes, VirtualMachineEvictionPolicyTypes, BillingProfile

SUBSCRIPTION_ID = '<subscription-id>'

GROUP_NAME = '<resource-group-name>'

LOCATION = 'Australia East'

VM_NAME = '<vm-name>'

credentials = DefaultAzureCredential()

compute_client = ComputeManagementClient(

credentials,

SUBSCRIPTION_ID

)

vm_parameters = {

'location': LOCATION,

'os_profile': {

'computer_name': VM_NAME,

'admin_username': '<username-accroding-to-naming-convention>',

'admin_password': '<password-according-to-naming-convention>'

},

'hardware_profile': {

'vm_size': 'Standard_D2s_v3'

},

'storage_profile': {

'image_reference': {

'publisher': 'MicrosoftWindowsServer',

'offer': 'WindowsServer',

'sku': '2019-Datacenter',

'version': 'latest'

}

},

'network_profile': {

'network_interfaces': [{

'id': "nic-id"

}]

},

'priority': VirtualMachinePriorityTypes.spot, # use Azure spot intance

'eviction_policy': VirtualMachineEvictionPolicyTypes.deallocate, # For Azure Spot virtual machines, the only supported value is 'Deallocate'

'billing_profile': BillingProfile(max_price=float(2))

}

  
  

creation_result = compute_client.virtual_machines.begin_create_or_update(

GROUP_NAME,

VM_NAME,

vm_parameters

)

print(creation_result.result())

Output:-

VM got created on Portal and I attached NSG and Public IP to the VM and tried to RDP into it with the credentials given in the code and it was successful, Refer below:-
