Azure ARM Compute Driver Documentation

Azure driver allows you to integrate with Microsoft Azure Virtual Machines provider using the Azure Resource Management (ARM) API.

Azure Virtual Machine service allows you to launch Windows and Linux virtual servers in many datacenters across the world.

Connecting to Azure

To connect to Azure you need your tenant ID and subscription ID. Using the Azure cross platform CLI, use az account list to get these values.

Creating a Service Principal

The following directions are based on https://azure.microsoft.com/en-us/documentation/articles/resource-group-authenticate-service-principal/

az ad app create --display-name "<Your Application Display Name>" --identifier-uris "<https://YouApplicationUri>" --password <Your_Password>
az ad sp create --id "<Application_Id>"
az role assignment create --assignee "<Object_Id>" --role Owner --scope /subscriptions/{subscriptionId}/

Instantiating a driver

Use <Application_Id> for “key” and the <Your_Password> for “secret”.

Once you have the tenant id, subscription id, application id (“key”), and password (“secret”), you can create an AzureNodeDriver:

from libcloud.compute.types import Provider
from libcloud.compute.providers import get_driver

cls = get_driver(Provider.AZURE_ARM)
driver = cls(
    tenant_id="tenant_id",
    subscription_id="subscription_id",
    key="application_id",
    secret="password",
)

Alternate Cloud Environments

You can select an alternate cloud environment using the “cloud_environment” parameter to AzureNodeDriver constructor. Available alternate cloud environments are ‘AzureChinaCloud’, ‘AzureUSGovernment’ and ‘AzureGermanCloud’. You can also supply explicit endpoints by providing a dict with the keys ‘resourceManagerEndpointUrl’, ‘activeDirectoryEndpointUrl’, ‘activeDirectoryResourceId’ and ‘storageEndpointSuffix’.

Create a new node instance. This instance will be started automatically.

This driver supports the ssh_key feature flag for created_node so you can upload a public key into the new instance:

>>> from libcloud.compute.drivers.azure_arm import AzureNodeDriver
>>> driver = AzureNodeDriver(...)
>>> auth = NodeAuthSSHKey('pubkey data here')
>>> node = driver.create_node("test_node", auth=auth)

This driver also supports the password feature flag for create_node so you can set a password:

>>> driver = AzureNodeDriver(...)
>>> auth = NodeAuthPassword('mysecretpassword')
>>> node = driver.create_node("test_node", auth=auth, ...)

If you don’t provide the auth argument libcloud will assign a password:

>>> driver = AzureNodeDriver(...)
>>> node = driver.create_node("test_node", ...)
>>> password = node.extra["properties"]                            ["osProfile"]["adminPassword"]

deploy_node(deploy, ssh_username='root', ssh_alternate_usernames=None, ssh_port=22, ssh_timeout=10, ssh_key=None, ssh_key_password=None, auth=None, timeout=300, max_tries=3, ssh_interface='public_ips', at_exit_func=None, wait_period=5, **create_node_kwargs)

Create a new node, and start deployment.

In order to be able to SSH into a created node access credentials are required.

A user can pass either a NodeAuthPassword or NodeAuthSSHKey to the auth argument. If the create_node implementation supports that kind if credential (as declared in self.features['create_node']) then it is passed on to create_node. Otherwise it is not passed on to create_node and it is only used for authentication.

If the auth parameter is not supplied but the driver declares it supports generates_password then the password returned by create_node will be used to SSH into the server.

Finally, if the ssh_key_file is supplied that key will be used to SSH into the server.

This function may raise a DeploymentException, if a create_node call was successful, but there is a later error (like SSH failing or timing out). This exception includes a Node object which you may want to destroy if incomplete deployments are not desirable.

>>> from libcloud.compute.drivers.dummy import DummyNodeDriver
>>> from libcloud.compute.deployment import ScriptDeployment
>>> from libcloud.compute.deployment import MultiStepDeployment
>>> from libcloud.compute.base import NodeAuthSSHKey
>>> driver = DummyNodeDriver(0)
>>> key = NodeAuthSSHKey('...') # read from file
>>> script = ScriptDeployment("yum -y install emacs strace tcpdump")
>>> msd = MultiStepDeployment([key, script])
>>> def d():
...     try:
...         driver.deploy_node(deploy=msd)
...     except NotImplementedError:
...         print ("not implemented for dummy driver")
>>> d()
not implemented for dummy driver

Deploy node is typically not overridden in subclasses. The existing implementation should be able to handle most such.

Parameters
  • deploy (Deployment) – Deployment to run once machine is online and available to SSH.

  • ssh_username (str) – Optional name of the account which is used when connecting to SSH server (default is root)

  • ssh_alternate_usernames (list) – Optional list of ssh usernames to try to connect with if using the default one fails

    This method gets passed in two keyword arguments:

    • driver -> node driver in question

    • node -> created Node object

    Keep in mind that this function will only be called in such scenario. In case the method finishes (this includes throwing an exception), at exit handler function won’t be called.

  • wait_period (int) – How many seconds to wait between each iteration while waiting for node to transition into running state and have IP assigned. (default is 5)
