For instruction on installing the +Azure Python SDK see http://azure-sdk-for-python.readthedocs.org/ + +Authentication +-------------- +The order of precedence is command line arguments, environment variables, +and finally the [default] profile found in ~/.azure/credentials. + +If using a credentials file, it should be an ini formatted file with one or +more sections, which we refer to as profiles. The script looks for a +[default] section, if a profile is not specified either on the command line +or with an environment variable. The keys in a profile will match the +list of command line arguments below. + +For command line arguments and environment variables specify a profile found +in your ~/.azure/credentials file, or a service principal or Active Directory +user. + +Command line arguments: + - profile + - client_id + - secret + - subscription_id + - tenant + - ad_user + - password + +Environment variables: + - AZURE_PROFILE + - AZURE_CLIENT_ID + - AZURE_SECRET + - AZURE_SUBSCRIPTION_ID + - AZURE_TENANT + - AZURE_AD_USER + - AZURE_PASSWORD + +Run for Specific Host +----------------------- +When run for a specific host using the --host option, a resource group is +required.

A sample +azure_rm_inventory.ini is included. The name of the .ini file is the basename of the inventory script (in this case +'azure_rm_inventory') with a .ini extension. This provides you with the flexibility of copying and customizing this +script and having matching .ini files. Go forth and customize your Azure inventory! + +Powerstate: +----------- +The powerstate attribute indicates whether or not a host is running. If the value is 'running', the machine is +up. If the value is anything other than 'running', the machine is down, and will be unreachable. + +Examples: +--------- + Execute /bin/uname on all instances in the galaxy-qa resource group + $ ansible -i azure_rm_inventory.py galaxy-qa -m shell -a "/bin/uname -a" + + Use the inventory script to print instance specific information + $ contrib/inventory/azure_rm_inventory.py --host my_instance_host_name --pretty + + Use with a playbook + $ ansible-playbook -i contrib/inventory/azure_rm_inventory.py my_playbook.yml --limit galaxy-qa + + +Insecure Platform Warning +------------------------- +If you receive InsecurePlatformWarning from urllib3, install the +requests security packages: + + pip install requests[security] + + +author: + - Chris Houseknecht (@chouseknecht) + - Matt Davis (@nitzmahone) + +Company: Ansible by Red Hat + +Version: 1.0.0 +''' + +import argparse +import ConfigParser +import json +import os +import re +import sys + +from os.path import expanduser + +HAS_AZURE = True +HAS_AZURE_EXC = None + +try: + from msrestazure.azure_exceptions import CloudError + from azure.mgmt.compute import __version__ as azure_compute_version + from azure.common import AzureMissingResourceHttpError, AzureHttpError + from azure.common.credentials import ServicePrincipalCredentials, UserPassCredentials + from azure.mgmt.network.network_management_client import NetworkManagementClient,\ + NetworkManagementClientConfiguration + from azure.mgmt.resource.resources.resource_management_client import ResourceManagementClient,\ + ResourceManagementClientConfiguration + from azure.mgmt.compute.compute_management_client import ComputeManagementClient,\ + ComputeManagementClientConfiguration +except ImportError as exc: + HAS_AZURE_EXC = exc + HAS_AZURE = False + + +AZURE_CREDENTIAL_ENV_MAPPING = dict( + profile='AZURE_PROFILE', + subscription_id='AZURE_SUBSCRIPTION_ID', + client_id='AZURE_CLIENT_ID', + secret='AZURE_SECRET', + tenant='AZURE_TENANT', + ad_user='AZURE_AD_USER', + password='AZURE_PASSWORD' +) + +AZURE_CONFIG_SETTINGS = dict( + resource_groups='AZURE_RESOURCE_GROUPS', + tags='AZURE_TAGS', + include_powerstate='AZURE_INCLUDE_POWERSTATE', + group_by_resource_group='AZURE_GROUP_BY_RESOURCE_GROUP', + group_by_location='AZURE_GROUP_BY_LOCATION', + group_by_security_group='AZURE_GROUP_BY_SECURITY_GROUP', + group_by_tag='AZURE_GROUP_BY_TAG' +) + +AZURE_MIN_VERSION = "2016-03-30" + + +def azure_id_to_dict(id): + pieces = re.sub(r'^\/', '', id).split('/') + result = {} + index = 0 + while index < len(pieces) - 1: + result[pieces[index]] = pieces[index + 1] + index += 1 + return result + + +class AzureRM(object): + + def __init__(self, args): + self._args = args + self._compute_client = None + self._resource_client = None + self._network_client = None + + self.debug = False + if args.debug: + self.debug = True + + self.credentials = self._get_credentials(args) + if not self.credentials: + self.fail("Failed to get credentials.
