Terrafrom - Deploy to multiple azure subscriptions

To deploy resources to multiple Azure subscriptions using Terraform, you need to configure Terraform to authenticate with each Azure subscription separately and manage your configurations accordingly. Here's a general approach you can follow:

Prerequisites

  1. Azure Service Principal:

    • Create a service principal (SP) in each Azure subscription you want to deploy to.
    • Each SP should have sufficient permissions (Contributor role or custom roles with required permissions) in its respective subscription.

  2. Terraform Configuration:

    • Ensure you have Terraform installed on your local machine or CI/CD environment.
    • Use Terraform configuration files (.tf) to define your infrastructure resources.

Steps to Deploy to Multiple Azure Subscriptions

1. Authentication Setup

You need to authenticate Terraform with each Azure subscription using Service Principal credentials.

  • Option 1: Environment Variables: Set environment variables for each Azure subscription:

    export ARM_CLIENT_ID="Service Principal App ID" export ARM_CLIENT_SECRET="Service Principal Client Secret" export ARM_SUBSCRIPTION_ID="Azure Subscription ID" export ARM_TENANT_ID="Azure Tenant ID"

    Use these variables in your Terraform configuration:

    provider "azurerm" { client_id = var.ARM_CLIENT_ID client_secret = var.ARM_CLIENT_SECRET subscription_id = var.ARM_SUBSCRIPTION_ID tenant_id = var.ARM_TENANT_ID // other provider configurations }

  • Option 2: Terraform Configuration: Use variables directly in your Terraform configuration files:

    provider "azurerm" { client_id = "Service Principal App ID" client_secret = "Service Principal Client Secret" subscription_id = "Azure Subscription ID" tenant_id = "Azure Tenant ID" // other provider configurations }

2. Organize Terraform Workspaces or Directories

Depending on your project structure and deployment needs:

  • Workspaces: Use Terraform workspaces to manage different configurations for each subscription.

    terraform workspace new dev terraform workspace new prod

    Then switch between workspaces:

    terraform workspace select dev

  • Directories: Organize your Terraform configurations into separate directories for each subscription:

    project/ ├── dev/ │ └── main.tf ├── prod/ │ └── main.tf └── variables.tf

3. Deploy Resources

  • Navigate to the directory or workspace corresponding to the subscription you want to deploy to:

    cd dev

  • Initialize Terraform and apply your configurations:

    terraform init terraform apply

  • Repeat the above steps for each subscription (dev, prod, etc.).

Notes:

  • State Management: Ensure proper state management to avoid conflicts between deployments to different subscriptions. Use remote state storage (e.g., Azure Blob Storage, Azure Terraform backend) for production deployments.

  • Automation: Consider automating Terraform deployments using CI/CD pipelines (e.g., Azure DevOps, GitHub Actions) to streamline deployment processes across multiple subscriptions.

By following these steps, you can effectively deploy resources to multiple Azure subscriptions using Terraform, leveraging its flexibility and infrastructure-as-code capabilities. Adjust the configurations and workflows based on your specific project requirements and organizational policies.
