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
|
|
|
|
Environment variables:
|
|
- AZURE_PROFILE
|
|
- AZURE_CLIENT_ID
|
|
- AZURE_SECRET
|
|
- AZURE_SUBSCRIPTION_ID
|
|
- AZURE_TENANT
|
|
- AZURE_AD_USER
|
|
- AZURE_PASSWORD
|
|
- AZURE_CLOUD_ENVIRONMENT
|
|
|
|
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]
