Phase 01: Active Directory Preparation

Runbook Azure

DOCUMENT CATEGORY: Runbook SCOPE: Active Directory domain preparation PURPOSE: Configure AD infrastructure for Azure Local MASTER REFERENCE: Microsoft Learn - AD Prerequisites

Status: Active


Overview

Prepare the Active Directory domain infrastructure required for Azure Local deployment. This stage establishes the foundational identity services, organizational structure, and security configuration needed for cluster operations.

What This Stage Accomplishes

  • Active Directory organizational preparation
  • Organizational Unit (OU) structure creation
  • Security groups for access control
  • DNS configuration for cluster nodes
  • Service and administrative accounts
  • Group assignments and permissions

Prerequisites

  • Windows Server domain controllers deployed
  • Domain admin access
  • DNS server configuration
  • Azure Local requirements documentation

Active Directory Preparation Steps

Task 1: OU Creation & Pre-Creation Artifacts

Create the foundational OU structure in Active Directory.

  • Create MGMT OU on root domain
  • Create sub-OUs: Admins, Operations, Security Groups, Servers, Services
  • Create Clusters AzureLocal OUs

Task 2: Security Groups

Create 7 security groups for role-based access control of Azure Local operations. Group names follow the convention SG-{org_prefix}-{cluster_id}-AZL-{role}, driven by active_directory.security_groups.org_prefix and cluster_id in variables.yml.

Task 5: Group Assignments

Assign users and service accounts to security groups.

  • Add users to appropriate security groups
  • Configure group memberships
  • Assign group permissions
  • Validate group policies

View Step 5 Details

Validation Checklist

  • Active Directory domain deployed and functional
  • OU structure created and verified
  • All security groups created
  • DNS records configured and resolving
  • Service and admin accounts created
  • Group assignments completed
  • Domain controller replication verified

Next Steps

After completing Active Directory preparation, proceed to Phase 09 - Enterprise Network Readiness Validation to validate network prerequisites.
