Task 01: Configure Core Variables

DOCUMENT CATEGORY: Task SCOPE: Core Terraform variable configuration PURPOSE: Define customer and CI/CD integration variables MASTER REFERENCE: azurelocal-toolkit Variables

Status: Active Last Updated: 2026-02-07

---

Objective

Configure the core Terraform variables required for all CI/CD deployments, including customer details, environment settings, and CI/CD Infrastructure integration.

---

Prerequisites

• Customer short name (from project naming convention)
• Azure tenant ID
• Azure subscription ID
• CI/CD Infrastructure runner principal ID (from Part 1: CI/CD Infrastructure)
• Azure Local Entra ID group object ID (from Part 1: CI/CD Infrastructure)

---

Procedure

1. Open Terraform Variables File

Navigate to your source control project and open the Terraform variables file:

# Typically located at:
terraform/environments/<environment>/terraform.tfvars
# or
terraform.tfvars

2. Configure Customer Variables

Add the core customer variables:

# Customer Configuration
customer_name = "iic"        # Customer short name (lowercase, hyphens)
environment   = "prd"        # Environment: prd, dev, stg (max 3 chars)
location      = "eastus"     # Azure region (eastus, westus, centralus, etc.)
tenant_id     = "12345678-1234-1234-1234-123456789012" # Customer Azure tenant ID

3. Configure CI/CD Infrastructure Integration

Add the CI/CD Infrastructure variables from Part 2:

# CI/CD Infrastructure (from Part 1)
azurelocal_cicd = {
  runner_principal_id = "87654321-4321-4321-4321-210987654321" # CI/CD runner service principal
}

# Azure Local Entra ID Group (from Part 1)
azurelocal_group_object_id = "abcdef12-3456-7890-abcd-ef1234567890" # Azure Local management group

4. Add Optional Tags (Recommended)

# Optional: Resource tags
tags = {
 Customer = "Customer Name"
 Environment = "Production"
 ManagedBy = "Azure Local Cloud CI/CD"
 CostCenter = "IT Infrastructure"
}

---

Variable Reference

Variable	Type	Description	Required	Example
customer_name	string	Customer short name	✅	"iic"
environment	string	Environment identifier (max 3 chars)	✅	"prd", "dev", "stg"
location	string	Azure region for resource deployment	✅	"eastus", "westus"
tenant_id	string	Customer Azure tenant ID (GUID)	✅	"12345678-1234-..."
azurelocal_cicd.runner_principal_id	string	CI/CD runner service principal ID	✅	"87654321-4321-..."
azurelocal_group_object_id	string	Azure Local Entra ID group object ID	✅	"abcdef12-3456-..."
tags	map(string)	Optional resource tags	❌	{ Customer = "..." }

---

Validation

After configuration, verify:

• Customer name follows naming convention
• Environment code is valid (3 characters maximum)
• Azure region is correct and available
• Tenant ID is correct customer tenant GUID
• Runner principal ID matches CI/CD pipeline service principal from Part 1
• Azure Local group object ID matches Entra ID group from Part 1
• No syntax errors in HCL configuration

Example Complete Configuration

# terraform.tfvars

# Customer Configuration
customer_name = "acme"
environment   = "prd"
location      = "eastus"
tenant_id     = "a1b2c3d4-e5f6-7890-abcd-ef1234567890"

# CI/CD Infrastructure
azurelocal_cicd = {
  runner_principal_id = "11223344-5566-7788-99aa-bbccddeeff00"
}

# Azure Local Entra ID Group
azurelocal_group_object_id = "ffeeddcc-bbaa-9988-7766-554433221100"

# Optional Tags
tags = {
  Customer    = "Acme Corporation"
  Environment = "Production"
  ManagedBy   = "Azure Local CI/CD"
  CostCenter  = "IT-Infrastructure"
  Project     = "Azure Local Deployment"
}

---

Troubleshooting

Issue: Invalid customer_name format Solution: Customer name must be lowercase with hyphens only (e.g., acme, global-tech)

Issue: Invalid environment value Solution: Environment must be 3 characters or less: prd, dev, stg, qa, etc.

Issue: Azure region not available Solution: Verify region name with az account list-locations -o table

Issue: Cannot find runner principal ID Solution: Check Part 1 CI/CD Infrastructure deployment outputs or CI/CD pipeline variables
