Azure ARM template Azure Resource Manager
Azure Arm template is a management Service layer that helps you to create, manage, delete and update Azure resources.
Capabilities present in the Azure portal are also available via Azure CLI, Azure Powershell, Rest APIs & SDK
It helps to work with the resources in your solution as a group.
You can design a template for deployment which help for a different situation such as staging, testing, and production.
Azure Arm Template also helps to provide security, tagging, auditing, and managing resources after deployment.
Therefore, Azure Arm Template will make your deployment reliable faster, more secure, and more repeatable.
For Example, You will not have to create an Azure Virtual machine from the Azure portal and wait for its deployment.
With the help of Powershell and Azure CLI, you can use Arm Template which creates the Azure VM quickly.
Benefits Of Azure Resource Manager (ARM)
- Instead of handling resources individually you can manage, deploy and monitor all resources as a group.
- You can repeatedly deploy the solution throughout the development lifecycle with confidence and consistency
- Manage your infrastructure via Template instead of Scripts.
- However, you can define the dependencies between resources to correctly deploy the resources.
- As RBAC is integrated into the management platform, you can apply access control to all the services in the Azure resource group
- By applying tags to your resources you can logically organize all resources in your subscription.
- Therefore, by checking the tags you can identify the billing by seeing the cost of resources having the same tag.
- If we use the arm template, it assures us that, deployment will happen in the same way each time we use it.
How to create an Azure Virtual Machine from Azure Resource Manager
The template used in this article will deploy a single virtual machine running the Windows server operating system.
Creating an Azure Virtual machine with an Arm template consist of two steps.
First, we have to create an Azure resource group and then a virtual machine.
We are using a Powershell to create Our resource group so we will run the following cmdlet
$resourceGroupName = Read-Host -Prompt "Enter the Resource Group name"
$location = Read-Host -Prompt "Enter the location (i.e. centralus)"
$adminUsername = Read-Host -Prompt "Enter the administrator username"
$adminPassword = Read-Host -Prompt "Enter the administrator password" -AsSecureString
$dnsLabelPrefix = Read-Host -Prompt "Enter a unique DNS name for the public IP"
By running the above cmdlet, we will provide the Name of the Resource group, Location, Admin UserName, Password, and DNS label.
Once we set the above settings, we will use the JSON file from the Github on the location below
“https://raw.githubusercontent.com/Azure/azure-quickstart-templates/master/quickstarts/microsoft.compute/vm-simple-windows/azuredeploy.json
So, now we will run the following cmdlet to use the JSON file to create an Azure simple VM.
New-AzResourceGroup -Name $resourceGroupName -Location "$location"
New-AzResourceGroupDeployment `
-ResourceGroupName $resourceGroupName `
-TemplateUri "https://raw.githubusercontent.com/Azure/azure-quickstart-templates/master/quickstarts/microsoft.compute/vm-simple-windows/azuredeploy.json" `
-adminUsername $adminUsername `
-adminPassword $adminPassword `
-dnsLabelPrefix $dnsLabelPrefix
(Get-AzVm -ResourceGroupName $resourceGroupName).name
Creating Azure VM With Local PowerShell using Azure Arm Template
If you do not want to use the Azure portal to create Azure VM.
You can use the local PowerShell from your computer to connect to the Azure account.
After connecting to the Microsoft Azure Account.
You can download and save the JSON template from Github.
Now you can try to deploy the Azure VM directly from your computer
Note: You have to install the Azure Module to your computer before you connect to the Azure Account.
The cmdlet to install Azure-Module to your PowerShell is
Install-Module -Name Az -Scope CurrentUser -Repository PSGallery -Force
Steps to Create Azure VM With local Powershell
First of all, connect to the Azure Account by running the following cmdlet
Connect-account -TenantId xxxxx
Now create a Resource Group in your Azure
Our case - New-AzResourceGroup -ResourceGroupName NewRG6 Location EaseUS
We have created a New Azure resource group by the name of NewRG6 and the location EastUS
Now we will run the following cmdlet to pick the configuration of the VM from the JSON file.
New-AZresourceGroupDeployment -ResourceGroupName NewRG6 -TemplateUri K:\AZ\deployvm.jason
Note: I have downloaded the JSON file from GitHub and saved it to my K drive.
Therefore, now it will prompt for the Admin UserName and Password.
Once you provide that, it will create your Azure virtual machine in less than a minute.
