Azure External Inventory Script
===============================
Generates dynamic inventory by making API requests to the Azure Resource
Manager using the Azure Python SDK. 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
- cloud_environment
- adfs_authority_url
Environment variables:
- AZURE_PROFILE
- AZURE_CLIENT_ID
- AZURE_SECRET
- AZURE_SUBSCRIPTION_ID
- AZURE_TENANT
- AZURE_AD_USER
- AZURE_PASSWORD
- AZURE_CLOUD_ENVIRONMENT
- AZURE_ADFS_AUTHORITY_URL
Run for Specific Host
-----------------------
When run for a specific host using the --host option, a resource group is
required. For a specific host, this script returns the following variables:
{
"ansible_host": "XXX.XXX.XXX.XXX",
"computer_name": "computer_name2",
"fqdn": null,
"id": "/subscriptions/subscription-id/resourceGroups/galaxy-production/providers/Microsoft.Compute/virtualMachines/object-name",
"image": {
"offer": "CentOS",
"publisher": "OpenLogic",
"sku": "7.1",
"version": "latest"
},
"location": "westus",
"mac_address": "00-00-5E-00-53-FE",
"name": "object-name",
"network_interface": "interface-name",
"network_interface_id": "/subscriptions/subscription-id/resourceGroups/galaxy-production/providers/Microsoft.Network/networkInterfaces/object-name1",
"network_security_group": null,
"network_security_group_id": null,
"os_disk": {
"name": "object-name",
"operating_system_type": "Linux"
},
"plan": null,
"powerstate": "running",
"private_ip": "172.26.3.6",
"private_ip_alloc_method": "Static",
"provisioning_state": "Succeeded",
"public_ip": "XXX.XXX.XXX.XXX",
"public_ip_alloc_method": "Static",
"public_ip_id": "/subscriptions/subscription-id/resourceGroups/galaxy-production/providers/Microsoft.Network/publicIPAddresses/object-name",
"public_ip_name": "object-name",
"resource_group": "galaxy-production",
"security_group": "object-name",
"security_group_id": "/subscriptions/subscription-id/resourceGroups/galaxy-production/providers/Microsoft.Network/networkSecurityGroups/object-name",
"tags": {
"db": "database"
},
"type": "Microsoft.Compute/virtualMachines",
"virtual_machine_size": "Standard_DS4"
}
Groups
------
When run in --list mode, instances are grouped by the following categories:
- azure
- location
- resource_group
- security_group
- tag key
- tag key_value
Control groups using azure_rm.ini or set environment variables:
AZURE_GROUP_BY_RESOURCE_GROUP=yes
AZURE_GROUP_BY_LOCATION=yes
AZURE_GROUP_BY_SECURITY_GROUP=yes
AZURE_GROUP_BY_TAG=yes
Select hosts within specific resource groups by assigning a comma separated list to:
AZURE_RESOURCE_GROUPS=resource_group_a,resource_group_b
Select hosts for specific tag key by assigning a comma separated list of tag keys to:
AZURE_TAGS=key1,key2,key3
Select hosts for specific locations:
AZURE_LOCATIONS=eastus,westus,eastus2
Or, select hosts for specific tag key:value pairs by assigning a comma separated list key:value pairs to:
AZURE_TAGS=key1:value1,key2:value2
If you don't need the powerstate, you can improve performance by turning off powerstate fetching:
AZURE_INCLUDE_POWERSTATE=no
azure_rm.ini
------------
As mentioned above, you can control execution using environment variables or a .ini file. A sample
azure_rm.ini is included. The name of the .ini file is the basename of the inventory script (in this case
'azure_rm') with a .ini extension. It also assumes the .ini file is alongside the script. To specify
a different path for the .ini file, define the AZURE_INI_PATH environment variable:
export AZURE_INI_PATH=/path/to/custom.ini
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.py galaxy-qa -m shell -a "/bin/uname -a"
Use the inventory script to print instance specific information
$ contrib/inventory/azure_rm.py --host my_instance_host_name --pretty
Use with a playbook
$ ansible-playbook -i contrib/inventory/azure_rm.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]
