azure_rm – Azure Resource Manager inventory plugin

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 master node that executes this inventory.

  • python >= 2.7
  • azure >= 2.0.0

Parameters

Parameter Choices/Defaults Configuration 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 2.6

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

api_profile

string

added in 2.5

Default:

"latest"

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.

auth_source

string

added in 2.5

  • auto
  • cli
  • credential_file
  • env
  • msi

Controls the source of the credentials to use for authentication.

If not specified, ANSIBLE_AZURE_AUTH_SOURCE environment variable will be used and default to auto if variable is not defined.

auto will follow the default precedence of module parameters -> environment variables -> default profile in credential file ~/.azure/credentials.

When set to cli, the credentials will be sources from the default Azure CLI profile.

Can also be set via the ANSIBLE_AZURE_AUTH_SOURCE environment variable.

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.

batch_fetch

-

Default:

"yes"

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.

cert_validation_mode

string

added in 2.5

  • ignore
  • validate

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.

client_id

string

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

cloud_environment

string

added in 2.4

Default:

"AzureCloud"

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.

conditional_groups

-

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

-

Default:

["powerstate != \"running\"", "provisioning_state != \"succeeded\""]

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.

exclude_host_filters

-

Default:

[]

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.

fail_on_template_errors

-

  • yes

  • no

Default:

"yes"

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)

hostvar_expressions

-

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

-

Default:

["*"]

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

include_vmss_resource_groups

-

Default:

[]

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

keyed_groups

-

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 _)

password

-

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

plain_host_names

boolean

added in 2.8

  • no

  • yes

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.

plugin

- / required

  • azure_rm

marks this as an instance of the 'azure_rm' plugin

profile

string

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

secret

string

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

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

  • no

  • yes

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.



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.

Configuration entries for each entry type have a low to high priority order. For example, a variable that is lower in the list will override a variable that is higher up.
