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"]
