Azure Windows Virtual Machine

This module creates a Windows Virtual Machine with Windows Remote Management (WinRM) activated.

The Windows Virtual Machine comes with:

• Azure Monitor Agent activated and configured
• A link to a Log Analytics Workspace for logging and patching management
• An optional link to a Load Balancer or Application Gateway
• A link to the Recovery Vault and one of its policies to back up the virtual machine
• Optional certificates retrieved from Azure Key Vault

This code is mostly based on Tom Harvey work: https://github.com/terraform-providers/terraform-provider-azurerm/tree/master/examples/virtual-machines/provisioners/windows

Following tags are automatically set with default values: env, stack, os_family, os_distribution, os_version.

Limitations

• A self-signed certificate is generated and associated

Requirements

• Powershell CLI installed with pwsh executable available
• Azure powershell module installed
• The port 5986 must be reachable
• An Azure Key Vault configured with VM deployment enabled will be used
• An existing Log Analytics Workspace is mandatory for patching management
• An existing Azure Monitor Data Collection Rule is mandatory for monitoring ang logging management with Azure Monitor Agent
• Microsoft.Compute/InGuestAutoAssessmentVMPreview must be activated on the subscription to use patch_mode = "AutomaticByPlatform" patching option.

Ansible usage

The created virtual machine can be used with Ansible this way.

ansible all -i <public_ip_address>, -m win_ping -e ansible_user=<vm_username> -e ansible_password==<vm_password> -e ansible_connection=winrm -e ansible_winrm_server_cert_validation=ignore
