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 azure.azcollection 0.0.1

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

api_profile

string

added in azure.azcollection 0.0.1

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"

append_tags

boolean

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.

Choices:

  • false

  • true ← (default)

auth_source

string

added in azure.azcollection 0.0.1

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"

cert_validation_mode

string

added in azure.azcollection 0.0.1

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 or Managed Identity (msi).

Can also be set via the AZURE_CLIENT_ID environment variable.

cloud_environment

string

added in azure.azcollection 0.0.1

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"

disable_instance_discovery

boolean

added in azure.azcollection 2.3.0

Determines whether or not instance discovery is performed when attempting to authenticate. Setting this to true will completely disable both instance discovery and authority validation. This functionality is intended for use in scenarios where the metadata endpoint cannot be reached such as in private clouds or Azure Stack. The process of instance discovery entails retrieving authority metadata from https://login.microsoft.com/ to validate the authority. By setting this to **True**, the validation of the authority is disabled. As a result, it is crucial to ensure that the configured authority host is valid and trustworthy.

Set via credential file profile or the AZURE_DISABLE_INSTANCE_DISCOVERY environment variable.

Choices:

  • false ← (default)

  • true

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.
