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 -			Active Directory username. Use when authenticating with an Active Directory user rather than service principal.
adfs_authority_url - added in 2.6	Default: null		Azure AD authority url. Use when authenticating with Username/password, and has your own ADFS authority.
api_profile - 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 - added in 2.5	Choices: 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 - added in 2.5	Choices: validate ignore		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 -			Azure client ID. Use when authenticating with a Service Principal.
cloud_environment - 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 -	Choices: 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.
plugin - / required	Choices: azure_rm		marks this as an instance of the 'azure_rm' plugin
profile -			Security profile found in ~/.azure/credentials file.
secret -			Azure client secret. Use when authenticating with a Service Principal.
subscription_id -			Your Azure subscription Id.
tenant -			Azure tenant ID. Use when authenticating with a Service Principal.

Notes

Note

• For authentication with Azure you can pass parameters, set environment variables or use a profile stored in ~/.azure/credentials. Authentication is 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.

  # if none are found, the first public IP address.
  ansible_host: (public_dns_hostnames + public_ipv4_addresses) | first

# places hosts in dynamically-created groups based on a variable value.
keyed_groups:
# places each host in a group named 'tag_(tag name)_(tag value)' for each tag on a VM.
- prefix: tag
  key: tags
# places each host in a group named 'azure_loc_(location name)', depending on the VM's location
- prefix: azure_loc
  key: location
# places host in a group named 'some_tag_X' using the value of the 'sometag' tag on a VM as X, and defaulting to the
# value 'none' (eg, the group 'some_tag_none') if the 'sometag' tag is not defined for a VM.
- prefix: some_tag
  key: tags.sometag | default('none')

# excludes a host from the inventory when any of these expressions is true, can refer to any vars defined on the host

# excludes hosts in the eastus region
