This module adds an Azure subscription to Rubrik Security Cloud (RSC/Polaris) using an existing Azure tenant. It is designed to be used with the Terraform Module - Azure Rubrik Cloud Native Tenant module.
There are a few services you'll need in order to get this project off the ground:
- Terraform v1.5.1 or greater
- Rubrik Polaris Provider for Terraform - provides Terraform functions for Rubrik Security Cloud (Polaris)
- Install the Azure CLI tools - Needed for Terraform to authenticate with Azure
- Properly configure the backend for this module. See Configure the Backend in this README.md.

Before running Terraform using the azurerm_* or azapi_* data sources and resources, an authentication with Azure is required. Terraform Module for AzureRM CLI Authentication
provides a complete guide on how to authenticate Terraform with Azure. The following commands can be used from a command line interface with the Microsoft Azure CLI
to manually run Terraform:
az login --tenant <tenant_id>
Where <tenant_id> is the ID of the tenant to login to. If you only have one tenant you can remove the --tenant option.
Next before running this module, the subscription must be selected. Do this by running the command:
az account set --subscription <subscription_id>
Where <subscription_id> is the ID of the subscription where CCES will be deployed.
The directory can be initialized for Terraform use by running the terraform init command:
-> terraform init

If you'd like to know more about provider signing, you can read about it here:
https://www.terraform.io/docs/cli/plugins/signing.html
Terraform has created a lock file .terraform.lock.hcl to record the provider
selections it made above. Include this file in your version control repository
so that Terraform can guarantee to make the same selections by default when
you run "terraform init" in the future.
Terraform has been successfully initialized!
You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.
If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
Run terraform plan to get information about what will happen when we apply the configuration; this will test that everything is set up correctly.
We can now apply the configuration to add the Azure subscription to RSC using the terraform apply command.
Once the subscription no longer needs protection, it can be removed from RSC using the terraform destroy command, and entering yes when prompted.
To specify exocompute_details as an environment variable use something like this:
export TF_VAR_exocompute_details='{"exocompute_config_1":"{"region":"westus","subnet_name":"subnet1","vnet_name":"vnet1","vnet_resource_group_name":vnet_rg"}}
If you remove the last subscription from RSC for a tenant, the tenant will also be removed from RSC. To add another subscription for the tenant, the tenant will have to be added back again.
You may receive the following error when applying the Terraform plan:
╷
│ Error: failed to add subscription: failed to request addAzureCloudAccountWithoutOauth: graphql response body is an error (status code 200): NOT_FOUND: Failed to get service principal in the tenant. Azure may take some time to sync service principal. Please try after a minute (Azure error: [Unknown] Unknown service error) (code: 404, traceId: T908tqj5/shh8TMK9rX2lA==)

│ with polaris_azure_subscription.polaris,
│ on main.tf line 84, in resource "polaris_azure_subscription" "polaris":
│ 84: resource "polaris_azure_subscription" "polaris" {
│
If this happens, it's likely due to the last subscription in a tenant being removed from RSC, but the terraform.tfstate file remains from the Terraform Module - Azure Rubrik Cloud Native Tenant module. In this case when the last subscription was removed from RSC, the tenant was automatically removed by RSC. To solve this, re-run the Terraform Module - Azure Rubrik Cloud Native Tenant module to create a new service principal.
