How to provision a virtual machine in azure using python SDK from an image in azure? - azure-python-sdk

Question

I want to write a python code equivalent of creating a virtual machine from the azure portal using Create Vm button in an image resource which is present in a resource group in azure.
Any pointers or documentation related to this?

Answer 1

Try the sample code # provision_vm.py
# Import the needed credential and management objects from the libraries.
from azure.identity import AzureCliCredential
from azure.mgmt.resource import ResourceManagementClient
from azure.mgmt.network import NetworkManagementClient
from azure.mgmt.compute import ComputeManagementClient
import os
print(f"Provisioning a virtual machine...some operations might take a minute or two.")
# Acquire a credential object using CLI-based authentication.
credential = AzureCliCredential()
# Retrieve subscription ID from environment variable.
subscription_id = os.environ["AZURE_SUBSCRIPTION_ID"]
# Step 1: Provision a resource group
# Obtain the management object for resources, using the credentials from the CLI login.
resource_client = ResourceManagementClient(credential, subscription_id)
# Constants we need in multiple places: the resource group name and the region
# in which we provision resources. You can change these values however you want.
RESOURCE_GROUP_NAME = "PythonAzureExample-VM-rg"
LOCATION = "westus2"
# Provision the resource group.
rg_result = resource_client.resource_groups.create_or_update(RESOURCE_GROUP_NAME,
{
"location": LOCATION
}
)
print(f"Provisioned resource group {rg_result.name} in the {rg_result.location} region")
# For details on the previous code, see Example: Provision a resource group
# at https://learn.microsoft.com/azure/developer/python/azure-sdk-example-resource-group
# Step 2: provision a virtual network
# A virtual machine requires a network interface client (NIC). A NIC requires
# a virtual network and subnet along with an IP address. Therefore we must provision
# these downstream components first, then provision the NIC, after which we
# can provision the VM.
# Network and IP address names
VNET_NAME = "python-example-vnet"
SUBNET_NAME = "python-example-subnet"
IP_NAME = "python-example-ip"
IP_CONFIG_NAME = "python-example-ip-config"
NIC_NAME = "python-example-nic"
# Obtain the management object for networks
network_client = NetworkManagementClient(credential, subscription_id)
# Provision the virtual network and wait for completion
poller = network_client.virtual_networks.begin_create_or_update(RESOURCE_GROUP_NAME,
VNET_NAME,
{
"location": LOCATION,
"address_space": {
"address_prefixes": ["10.0.0.0/16"]
}
}
)
vnet_result = poller.result()
print(f"Provisioned virtual network {vnet_result.name} with address prefixes {vnet_result.address_space.address_prefixes}")
# Step 3: Provision the subnet and wait for completion
poller = network_client.subnets.begin_create_or_update(RESOURCE_GROUP_NAME,
VNET_NAME, SUBNET_NAME,
{ "address_prefix": "10.0.0.0/24" }
)
subnet_result = poller.result()
print(f"Provisioned virtual subnet {subnet_result.name} with address prefix {subnet_result.address_prefix}")
# Step 4: Provision an IP address and wait for completion
poller = network_client.public_ip_addresses.begin_create_or_update(RESOURCE_GROUP_NAME,
IP_NAME,
{
"location": LOCATION,
"sku": { "name": "Standard" },
"public_ip_allocation_method": "Static",
"public_ip_address_version" : "IPV4"
}
)
ip_address_result = poller.result()
print(f"Provisioned public IP address {ip_address_result.name} with address {ip_address_result.ip_address}")
# Step 5: Provision the network interface client
poller = network_client.network_interfaces.begin_create_or_update(RESOURCE_GROUP_NAME,
NIC_NAME,
{
"location": LOCATION,
"ip_configurations": [ {
"name": IP_CONFIG_NAME,
"subnet": { "id": subnet_result.id },
"public_ip_address": {"id": ip_address_result.id }
}]
}
)
nic_result = poller.result()
print(f"Provisioned network interface client {nic_result.name}")
# Step 6: Provision the virtual machine
# Obtain the management object for virtual machines
compute_client = ComputeManagementClient(credential, subscription_id)
VM_NAME = "ExampleVM"
USERNAME = "azureuser"
PASSWORD = "ChangePa$$w0rd24"
print(f"Provisioning virtual machine {VM_NAME}; this operation might take a few minutes.")
# Provision the VM specifying only minimal arguments, which defaults to an Ubuntu 18.04 VM
# on a Standard DS1 v2 plan with a public IP address and a default virtual network/subnet.
poller = compute_client.virtual_machines.begin_create_or_update(RESOURCE_GROUP_NAME, VM_NAME,
{
"location": LOCATION,
"storage_profile": {
"image_reference": {
"publisher": 'Canonical',
