Requirements

The below requirements are needed on the host that executes this module.

  • azure >= 2.0.0

Parameters

Parameter Choices/Defaults 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:
None
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.
append_tags
boolean
    Choices:
  • no
  • yes ←
Use to control if tags field is canonical or just appends to existing tags. When canonical, any tags not found in the tags parameter will be removed from the object's metadata.
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.
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.

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.
