Prerequisites

You need a Microsoft account
Your system needs the Microsoft Azure CLI as well as Terraform

Before deploy Terraform code for Microsoft Azure, you will need to authenticate under the Microsoft account you used to log into the Microsoft Azure Portal. You will use a Microsoft account and its credentials to allow Terraform to deploy resources.

DDN EXAScaler Cloud in the Azure Marketplace have additional license and purchase terms that you must accept before you can deploy them programmatically. To deploy an environment from this image, you'll need to accept the image's terms the first time you use it, once per subscription.

Steps to authenticate via Microsoft account

Obtains access credentials for your user account via a web-based authorization flow. When this command completes successfully, it sets the active account in the current configuration to the account specified. Learn more about Azure authentication.

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.
