az_resource_group: Azure resource group class

Description

Class representing an Azure resource group.

Usage

az_resource_group

Format

An R6 object of class az_resource_group.

Methods

• new(token, subscription, id, ...): Initialize a resource group object. See 'Initialization' for more details.

• delete(confirm=TRUE): Delete this resource group, after a confirmation check. This is asynchronous: while the method returns immediately, the delete operation continues on the host in the background. For resource groups containing a large number of deployed resources, this may take some time to complete.

• list_templates(): List deployed templates in this resource group.

• get_template(name): Return an object representing an existing template.

• deploy_template(...): Deploy a new template. See 'Templates' for more details.

• delete_template(name, confirm=TRUE, free_resources=FALSE): Delete a deployed template, and optionally free any resources that were created.

• get_resource(...): Return an object representing an existing resource. See 'Resources' for more details.

• create_resource(...): Create a new resource.

• delete_resource(..., confirm=TRUE, wait=FALSE): Delete an existing resource. Optionally wait for the delete to finish.

• resource_exists(...): Check if a resource exists.

• list_resources(): Return a list of resource group objects for this subscription.

Initialization

Initializing a new object of this class can either retrieve an existing resource group, or create a new resource group on the host. Generally, the easiest way to create a resource group object is via the get_resource_group, create_resource_group or list_resource_groups methods of the az_subscription class, which handle this automatically.

To create a resource group object in isolation, supply (at least) an Oauth 2.0 token of class AzureToken, the subscription ID, and the resource group name. If this object refers to a new resource group, supply the location as well (use the list_locations method of the az_subscription class for possible locations). You can also pass any optional parameters for the resource group as named arguments to new().

Templates

To deploy a new template, pass the following arguments to deploy_template():

• name: The name of the deployment.

• template: The template to deploy. This can be provided in a number of ways:

  1. A nested list of name-value pairs representing the parsed JSON

  2. The name of a template file

  3. A vector of strings containing unparsed JSON

  4. A URL from which the template can be downloaded

• parameters: The parameters for the template. This can be provided using any of the same methods as the template argument.

Retrieving or deleting a deployed template requires only the name of the deployment.

Resources

There are a number of arguments to get_resource(), create_resource() and delete_resource() that serve to identify the specific resource in question:

• id: The full ID of the resource, including subscription ID and resource group.

• provider: The provider of the resource, eg Microsoft.Compute.

• path: The full path to the resource, eg virtualMachines.

• type: The combination of provider and path, eg Microsoft.Compute/virtualMachines.

• name: The name of the resource instance, eg myWindowsVM.

Providing the id argument will fill in the values for all the other arguments. Similarly, providing the type argument will fill in the values for provider and path. Unless you provide id, you must also provide name.

To create/deploy a new resource, specify any extra parameters that the provider needs as named arguments to create_resource().

Examples

# NOT RUN {
# recommended way to retrieve a resource group object
rg <- az_rm$
    new(tenant="myaadtenant.onmicrosoft.com", app="app_id", password="password")$
    get_subscription("subscription_id")$
    get_resource_group("rgname")

# list resources & templates in this resource group
rg$list_resources()
rg$list_templates()

# get a resource (virtual machine)
rg$get_resource(type="Microsoft.Compute/virtualMachines", name="myvm")

# create a resource (storage account)
rg$create_resource(type="Microsoft.Storage/storageAccounts", name="mystorage",
    kind="StorageV2",
    sku=list(name="Standard_LRS"))

# delete a resource
rg$delete_resource(type="Microsoft.Storage/storageAccounts", name="mystorage")

# deploy a template
rg$deploy_template("tplname",
    template="template.json",
    parameters="parameters.json")

# deploy a template with parameters inline
rg$deploy_template("mydeployment",
    template="template.json",
    parameters=list(parm1="foo", parm2="bar"))

# delete a template and free resources
rg$delete_template("tplname", free_resources=TRUE)

# delete the resource group itself
rg$delete()

# }
