Azure Resource Manager template overview

Resource Manager templates let you define Azure infrastructure in code. The required resources, network connections, or configuration of VMs can all be defined in a template. These templates create consistent, reproducible deployments each time, and can be versioned as you make changes.

For more information, see Azure Resource Manager templates overview.

Each resource is defined in a template using JavaScript Object Notation (JSON). The following JSON example uses the Microsoft.Compute/virtualMachines/extensions resource type to install the Active

Directory domain join extension. Parameters are used that you specify at deployment time. When the extension is deployed, the VM is joined to the specified managed domain.

{

"apiVersion": "2015-06-15",

"type": "Microsoft.Compute/virtualMachines/extensions",

"name": "[concat(parameters('dnsLabelPrefix'),'/joindomain')]",

"location": "[parameters('location')]",

"dependsOn": [

"[concat('Microsoft.Compute/virtualMachines/', parameters('dnsLabelPrefix'))]"

],

"properties": {

"publisher": "Microsoft.Compute",

"type": "JsonADDomainExtension",

"typeHandlerVersion": "1.3",

"autoUpgradeMinorVersion": true,

"settings": {

"Name": "[parameters('domainToJoin')]",

"OUPath": "[parameters('ouPath')]",

"User": "[concat(parameters('domainToJoin'), '\\', parameters('domainUsername'))]",

"Restart": "true",

"Options": "[parameters('domainJoinOptions')]"

},

"protectedSettings": {

"Password": "[parameters('domainPassword')]"

}

}

}

This VM extension can be deployed even if you don't create a VM in the same template. The examples in this article show both of the following approaches:

Create a Windows Server VM and join to a managed domain

Join an existing Windows Server VM to a managed domain
