Compute and Network Resource Management
=======================================
For general information on resource management, see :doc:`Resource Management<resourcemanagement>`.
Create the management client
----------------------------
The following code creates an instance of the management client.
You will need to provide your ``subscription_id`` which can be retrieved
from `your subscription list <https://manage.windowsazure.com/#Workspaces/AdminTasks/SubscriptionMapping>`__.
See :doc:`Resource Management Authentication <resourcemanagementauthentication>`
for details on getting a ``Credentials`` instance.
.. code:: python
from azure.mgmt.compute import ComputeManagementClient
from azure.mgmt.network import NetworkManagementClient
# TODO: Replace this with your subscription id
subscription_id = '33333333-3333-3333-3333-333333333333'
# TODO: See above how to get a Credentials instance
credentials = ...
compute_client = ComputeManagementClient(
credentials,
subscription_id
)
network_client = NetworkManagementClient(
credentials,
subscription_id
)
Registration
------------
Some operations in the compute/network ARM APIs require a one-time
registration of the storage provider with your subscription.
Use the following code to do the registration. You can use the same
credentials you created in the previous section.
.. code:: python
from azure.mgmt.resource.resources import ResourceManagementClient
resource_client = ResourceManagementClient(
credentials,
subscription_id
)
resource_client.providers.register('Microsoft.Compute')
resource_client.providers.register('Microsoft.Network')
List images
-----------
Use the following code to print all of the available images to use for
creating virtual machines, including all skus and versions.
.. code:: python
region = 'eastus2'
result_list_pub = compute_client.virtual_machine_images.list_publishers(
region,
)
for publisher in result_list_pub:
result_list_offers = compute_client.virtual_machine_images.list_offers(
region,
publisher.name,
)
for offer in result_list_offers:
result_list_skus = compute_client.virtual_machine_images.list_skus(
region,
publisher.name,
offer.name,
)
for sku in result_list_skus:
result_list = compute_client.virtual_machine_images.list(
region,
publisher.name,
offer.name,
sku.name,
)
for version in result_list:
result_get = compute_client.virtual_machine_images.get(
region,
publisher.name,
offer.name,
sku.name,
version.name,
)
print('PUBLISHER: {0}, OFFER: {1}, SKU: {2}, VERSION: {3}'.format(
publisher.name,
offer.name,
sku.name,
version.name,
))
Create virtual machine
----------------------
The following code creates a new virtual machine. Creating a virtual
machine involves creating a resource group, storage accounts, virtual
network resources, and finally the virtual machine.
To create or manage resource groups, see :doc:`Resource Management<resourcemanagement>`.
To create or manage storage accounts, see :doc:`Storage Resource Management<resourcemanagementstorage>`.
.. code:: python
import azure.mgmt.compute
import azure.mgmt.network
import azure.mgmt.resource
import azure.mgmt.storage
resource_client = azure.mgmt.resource.ResourceManagementClient(res_config)
storage_client = azure.mgmt.storage.StorageManagementClient(storage_config)
compute_client = azure.mgmt.compute.ComputeManagementClient(compute_config)
network_client = azure.mgmt.network.NetworkManagementClient(network_config)
BASE_NAME = 'pythonexample'
GROUP_NAME = BASE_NAME
STORAGE_NAME = BASE_NAME
VIRTUAL_NETWORK_NAME = BASE_NAME
SUBNET_NAME = BASE_NAME

# 2. Create a storage account
result = storage_client.storage_accounts.create(

azure.mgmt.storage.models.StorageAccountCreateParameters(

uri='https://{0}.blob.core.windows.net/vhds/{1}.vhd'.format(
STORAGE_NAME,
OS_DISK_NAME,
),
),
),
image_reference = azure.mgmt.compute.models.ImageReference(
publisher=IMAGE_PUBLISHER,
offer=IMAGE_OFFER,
sku=IMAGE_SKU,
version=IMAGE_VERSION,
),
),
),
)
# Display the public ip address
# You can now connect to the machine using SSH
public_ip_address = network_client.public_ip_addresses.get(GROUP_NAME, PUBLIC_IP_NAME)
print('VM available at {}'.format(public_ip_address.ip_address))
This is the helper function that creates the network resources, such as
virtual network, public ip and network interface.

def create_network_interface(network_client, region, group_name, interface_name,
network_name, subnet_name, ip_name):
