Prerequisites

Azure CLI initialization and subscription setup required before Terraform deployments.

[!NOTE] Part of the Deployment Guide. Return there for navigation and deployment order.

📜 Scripts

Script	Purpose
az-sub-init.sh	Azure login and ARM_SUBSCRIPTION_ID export
register-azure-providers.sh	Register required Azure resource providers

🚀 Usage

Source the initialization script to set ARM_SUBSCRIPTION_ID for Terraform:

source az-sub-init.sh

For a specific tenant:

source az-sub-init.sh --tenant your-tenant.onmicrosoft.com

For new Azure subscriptions or subscriptions that haven't deployed AKS, AzureML, or similar resources, register the required providers:

./register-azure-providers.sh

The script reads providers from robotics-azure-resource-providers.txt and waits for registration to complete. This is a one-time operation per subscription.

⚙️ What It Does

az-sub-init.sh

1. Checks for existing Azure CLI session
2. Prompts for login if needed (optionally with tenant)
3. Exports ARM_SUBSCRIPTION_ID to current shell

The subscription ID is required by Terraform's Azure provider when not running in a managed identity context.

register-azure-providers.sh

1. Reads required providers from robotics-azure-resource-providers.txt
2. Checks current registration state via Azure CLI
3. Registers unregistered providers
4. Polls until all providers reach Registered state

➡️ Next Step

After initialization, proceed to Infrastructure Deployment to deploy Azure resources.
