AzureRMR (version 2.4.5)

az_rm: Azure Resource Manager

Description

Base class for interacting with Azure Resource Manager.

Format

An R6 object of class az_rm.

Methods

• new(tenant, app, ...): Initialize a new ARM connection with the given credentials. See 'Authentication` for more details.

• list_subscriptions(): Returns a list of objects, one for each subscription associated with this app ID.

• get_subscription(id): Returns an object representing a subscription.

• get_subscription_by_name(name): Returns the subscription with the given name (as opposed to a GUID).

• do_operation(...): Carry out an operation. See 'Operations' for more details.

Authentication

The recommended way to authenticate with ARM is via the get_azure_login function, which creates a new instance of this class.

To authenticate with the az_rm class directly, provide the following arguments to the new method:

• tenant: Your tenant ID. This can be a name ("myaadtenant"), a fully qualified domain name ("myaadtenant.onmicrosoft.com" or "mycompanyname.com"), or a GUID.

• app: The client/app ID to use to authenticate with Azure Active Directory. The default is to login interactively using the Azure CLI cross-platform app, but it's recommended to supply your own app credentials if possible.

• password: if auth_type == "client_credentials", the app secret; if auth_type == "resource_owner", your account password.

• username: if auth_type == "resource_owner", your username.

• certificate: If `auth_type == "client_credentials", a certificate to authenticate with. This is a more secure alternative to using an app secret.

• auth_type: The OAuth authentication method to use, one of "client_credentials", "authorization_code", "device_code" or "resource_owner". See get_azure_token for how the default method is chosen, along with some caveats.

• version: The Azure Active Directory version to use for authenticating.

• host: your ARM host. Defaults to https://management.azure.com/. Change this if you are using a government or private cloud.

• aad_host: Azure Active Directory host for authentication. Defaults to https://login.microsoftonline.com/. Change this if you are using a government or private cloud.

• ...: Further arguments to pass to get_azure_token.

• scopes: The Azure Service Management scopes (permissions) to obtain for this login. Only for version=2.

• token: Optionally, an OAuth 2.0 token, of class AzureAuth::AzureToken. This allows you to reuse the authentication details for an existing session. If supplied, all other arguments will be ignored.

Operations

The do_operation() method allows you to carry out arbitrary operations on the Resource Manager endpoint. It takes the following arguments:

• op: The operation in question, which will be appended to the URL path of the request.

• options: A named list giving the URL query parameters.

• ...: Other named arguments passed to call_azure_rm, and then to the appropriate call in httr. In particular, use body to supply the body of a PUT, POST or PATCH request, and api_version to set the API version.

• http_verb: The HTTP verb as a string, one of GET, PUT, POST, DELETE, HEAD or PATCH.

Consult the Azure documentation for what operations are supported.
