azure.azcollection.azure_rm – Azure Resource Manager inventory plugin

Note

This plugin is part of the azure.azcollection collection (version 1.10.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install azure.azcollection.

To use it in a playbook, specify: azure.azcollection.azure_rm.

Synopsis

  • Query VM details from Azure Resource Manager

  • Requires a YAML configuration file whose name ends with ‘azure_rm.(yml|yaml)’

  • By default, sets ansible_host to the first public IP address found (preferring the primary NIC). If no public IPs are found, the first private IP (also preferring the primary NIC). The default may be overridden via hostvar_expressions; see examples.

Requirements

The below requirements are needed on the local controller node that executes this inventory.

  • python >= 2.7

  • The host that executes this module must have the azure.azcollection collection installed via galaxy

  • All python packages listed in collection’s requirements-azure.txt must be installed via pip on the host that executes modules from azure.azcollection

  • Full installation instructions may be found https://galaxy.ansible.com/azure/azcollection

Parameters

Parameter

Comments

ad_user

string

Active Directory username. Use when authenticating with an Active Directory user rather than service principal.

adfs_authority_url

string

added in 0.0.1 of azure.azcollection

Azure AD authority url. Use when authenticating with Username/password, and has your own ADFS authority.

api_profile

string

added in 0.0.1 of azure.azcollection

Selects an API profile to use when communicating with Azure services. Default value of latest is appropriate for public clouds; future values will allow use with Azure Stack.

Default: “latest”

auth_source

string

added in 0.0.1 of azure.azcollection

Controls the source of the credentials to use for authentication.

Can also be set via the ANSIBLE_AZURE_AUTH_SOURCE environment variable.

When set to auto (the default) the precedence is module parameters -> env -> credential_file -> cli.

When set to env, the credentials will be read from the environment variables

When set to credential_file, it will read the profile from ~/.azure/credentials.

When set to cli, the credentials will be sources from the Azure CLI profile. subscription_id or the environment variable AZURE_SUBSCRIPTION_ID can be used to identify the subscription ID if more than one is present otherwise the default az cli subscription is used.

When set to msi, the host machine must be an azure resource with an enabled MSI extension. subscription_id or the environment variable AZURE_SUBSCRIPTION_ID can be used to identify the subscription ID if the resource is granted access to more than one subscription, otherwise the first subscription is chosen.

The msi was added in Ansible 2.6.

Choices:

  • auto ← (default)

  • cli

  • credential_file

  • env

  • msi

batch_fetch

string

To improve performance, results are fetched using an unsupported batch API. Disabling batch_fetch uses a much slower serial fetch, resulting in many more round-trips. Generally only useful for troubleshooting.

Default: “yes”

cert_validation_mode

string

added in 0.0.1 of azure.azcollection

Controls the certificate validation behavior for Azure endpoints. By default, all modules will validate the server certificate, but when an HTTPS proxy is in use, or against Azure Stack, it may be necessary to disable this behavior by passing ignore. Can also be set via credential file profile or the AZURE_CERT_VALIDATION environment variable.

Choices:

  • ignore

  • validate

client_id

string

Azure client ID. Use when authenticating with a Service Principal.

cloud_environment

string

added in 0.0.1 of azure.azcollection

For cloud environments other than the US public cloud, the environment name (as defined by Azure Python SDK, eg, AzureChinaCloud, AzureUSGovernment), or a metadata discovery endpoint URL (required for Azure Stack). Can also be set via credential file profile or the AZURE_CLOUD_ENVIRONMENT environment variable.

Default: “AzureCloud”

compose

dictionary

Create vars from jinja2 expressions.

Default: {}

conditional_groups

string

A mapping of group names to Jinja2 expressions. When the mapped expression is true, the host is added to the named group.

default_host_filters

string

A default set of filters that is applied in addition to the conditions in exclude_host_filters to exclude powered-off and not-fully-provisioned hosts. Set this to a different value or empty list if you need to include hosts in these states.

Default: [“powerstate != \”running\””, “provisioning_state != \”succeeded\””]

exclude_host_filters

string

Excludes hosts from the inventory with a list of Jinja2 conditional expressions. Each expression in the list is evaluated for each host; when the expression is true, the host is excluded from the inventory.

Default: []

fail_on_template_errors

string

When false, template failures during group and filter processing are silently ignored (eg, if a filter or group expression refers to an undefined host variable)

Choices:

  • True

  • False

Default: “yes”

groups

dictionary

Add hosts to group based on Jinja2 conditionals.

Default: {}

hostnames

list / elements=string

A list of Jinja2 expressions in order of precedence to compose inventory_hostname.

Ignores expression if result is an empty string or None value.

By default, inventory_hostname is generated to be globally unique based on the VM host name. See plain_host_names for more details on the default.

An expression of ‘default’ will force using the default hostname generator if no previous hostname expression resulted in a valid hostname.

Use default_inventory_hostname to access the default hostname generator’s value in any of the Jinja2 expressions.

Default: [“default”]

hostvar_expressions

string

A mapping of hostvar names to Jinja2 expressions. The value for each host is the result of the Jinja2 expression (which may refer to any of the host’s existing variables at the time this inventory plugin runs).

include_vm_resource_groups

string

A list of resource group names to search for virtual machines. ‘*’ will include all resource groups in the subscription.

Default: [“*”]

include_vmss_resource_groups

string

A list of resource group names to search for virtual machine scale sets (VMSSs). ‘*’ will include all resource groups in the subscription.

Default: []

keyed_groups

list / elements=string

Creates groups based on the value of a host variable. Requires a list of dictionaries, defining key (the source dictionary-typed variable), prefix (the prefix to use for the new group name), and optionally separator (which defaults to _)

Default: []

leading_separator

boolean

added in 2.11 of ansible.builtin

Use in conjunction with keyed_groups.

By default, a keyed group that does not have a prefix or a separator provided will have a name that starts with an underscore.

This is because the default prefix is “” and the default separator is “_”.

Set this option to False to omit the leading underscore (or other separator) if no prefix is given.

If the group name is derived from a mapping the separator is still used to concatenate the items.

To not use a separator in the group name at all, set the separator for the keyed group to an empty string instead.

Choices:

  • no

  • yes ← (default)

log_mode

string

Parent argument.

log_path

string

Parent argument.

password

string

Active Directory user password. Use when authenticating with an Active Directory user rather than service principal.

plain_host_names

boolean

added in 2.8 of azure.azcollection

By default this plugin will use globally unique host names. This option allows you to override that, and use the name that matches the old inventory script naming.

This is not the default, as these names are not truly unique, and can conflict with other hosts. The default behavior will add extra hashing to the end of the hostname to prevent such conflicts.

Choices:

  • no ← (default)

  • yes

plugin

string / required

marks this as an instance of the ‘azure_rm’ plugin

Choices:

  • azure_rm

  • azure.azcollection.azure_rm

profile

string

Security profile found in ~/.azure/credentials file.

secret

string

Azure client secret. Use when authenticating with a Service Principal.

strict

boolean

If yes make invalid entries a fatal error, otherwise skip and continue.

Since it is possible to use facts in the expressions they might not always be available and we ignore those errors by default.

Choices:

  • no ← (default)

  • yes

subscription_id

string

Your Azure subscription Id.

tenant

string

Azure tenant ID. Use when authenticating with a Service Principal.

use_contrib_script_compatible_sanitization

boolean

added in 2.8 of azure.azcollection

By default this plugin is using a general group name sanitization to create safe and usable group names for use in Ansible. This option allows you to override that, in efforts to allow migration from the old inventory script and matches the sanitization of groups when the script’s replace_dash_in_groups option is set to False. To replicate behavior of replace_dash_in_groups = True with constructed groups, you will need to replace hyphens with underscores via the regex_replace filter for those entries.

For this to work you should also turn off the TRANSFORM_INVALID_GROUP_CHARS setting, otherwise the core engine will just use the standard sanitization on top.

This is not the default as such names break certain functionality as not all characters are valid Python identifiers which group names end up being used as.

Choices:

  • no ← (default)

  • yes

use_extra_vars

boolean

added in 2.11 of ansible.builtin

Merge extra vars into the available variables for composition (highest precedence).

Choices:

  • no ← (default)

  • yes

Configuration:

  • INI entry:

    [inventory_plugins]
use_extra_vars = no

  • Environment variable: ANSIBLE_INVENTORY_USE_EXTRA_VARS

Notes

Note

  • For authentication with Azure you can pass parameters, set environment variables, use a profile stored in ~/.azure/credentials, or log in before you run your tasks or playbook with az login.

  • Authentication is also possible using a service principal or Active Directory user.

  • To authenticate via service principal, pass subscription_id, client_id, secret and tenant or set environment variables AZURE_SUBSCRIPTION_ID, AZURE_CLIENT_ID, AZURE_SECRET and AZURE_TENANT.

  • To authenticate via Active Directory user, pass ad_user and password, or set AZURE_AD_USER and AZURE_PASSWORD in the environment.

  • Alternatively, credentials can be stored in ~/.azure/credentials. This is an ini file containing a [default] section and the following keys: subscription_id, client_id, secret and tenant or subscription_id, ad_user and password. It is also possible to add additional profiles. Specify the profile by passing profile or setting AZURE_PROFILE in the environment.
