So you want to create a Virtual Machine on Azure, this can be done in the portal. But really we want this scriptable, so that we can run it at a later date if needed and also so we can leverage this work and use it to create other virtual machines at a later date.
First, fire up a PowerShell console and login to your subscription:
We need to create a Resource Group, this is a logical place to group all the elements that we’re going to create.
$resourceGroup = "test-infra" $location = "North Europe" New-AzureRmResourceGroup -Name $resourceGroup -Location $location
Now we need a storage account where our virtual machine data will be stored
The storage account name has to be unique globally, so make sure you rename here
$storageAccountName = "teststorage1x2" # Add random number/characters here New-AzureRmStorageAccount -Name $storageAccountName -ResourceGroupName $resourceGroup -Type Standard_LRS -Location $location
We need a Virtual Network where our Virtual Machine will live.
$vnetName = "test-net" $subnet = New-AzureRmVirtualNetworkSubnetConfig -Name frontendSubnet -AddressPrefix 10.0.1.0/24 $vnet = New-AzureRmVirtualNetwork -Name $vnetName -ResourceGroupName $resourceGroup -Location $location -AddressPrefix 10.0.0.0/16 -Subnet $subnet
Our Virtual Machine needs a Network Interface and IP Address associated with it. We’re going to create a Dynamic IP Address for now, but you can have a static IP Address too.
$nicName ="testvm-nic" $pip = New-AzureRmPublicIpAddress -Name $nicName -ResourceGroupName $resourceGroup -Location $location -AllocationMethod Dynamic $nic = New-AzureRmNetworkInterface -Name $nicName -ResourceGroupName $resourceGroup -Location $location -SubnetId $vnet.Subnets.Id -PublicIpAddressId $pip.Id
Now we can begin with the actual configuation of the Virtual Machine. We’ll give it a name of testvm1, and have a size of Basic A1.
$vmName = "testvm1" $vm = New-AzureRmVMConfig -VMName $vmName -VMSize "Basic_A1"
We create a $cred object to be used later, you can either have the script prompt you for your credentials, or have it hard coded in your script. I would suggest prompt you, as you don’t want to store your password in plain text anywhere.
$cred=Get-Credential -Message "Admin credentials" # Either this for the prompt or #$username = "YOURUSERNAME" #$password = ConvertTo-SecureString "YOUR_PASSWORD" -AsPlainText -Force #$cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $username, $password
We want a Windows Virtual Machine, and pass in the $cred object that we just setup. We can choose which Windows image we want from the Azure gallery, here I have selected the Windows 2012 R2 Datacenter image.
$vm = Set-AzureRmVMOperatingSystem -VM $vm -Windows -ComputerName $vmName -Credential $cred -ProvisionVMAgent -EnableAutoUpdate $vm = Set-AzureRmVMSourceImage -VM $vm -PublisherName "MicrosoftWindowsServer" -Offer "WindowsServer" -Skus "2012-R2-Datacenter" -Version "latest"
$vm = Add-AzureRmVMNetworkInterface -VM $vm -Id $nic.Id
Our Virtual Machine needs somewhere to save itself obviously. So we create a new VHD in the Storage Account we setup earlier.
$diskName="os-disk" $storageAcc=Get-AzureRmStorageAccount -ResourceGroupName $resourceGroup -Name $storageAccountName $osDiskUri= $storageAcc.PrimaryEndpoints.Blob.ToString() + "vhds/" + $diskName + ".vhd" $vm=Set-AzureRmVMOSDisk -VM $vm -Name $diskName -VhdUri $osDiskUri -CreateOption fromImage
Everything should now be configured, it’s time to create the actual Virtual Machine.
New-AzureRmVM -ResourceGroupName $resourceGroup -Location $location -VM $vm
So there we go, we now have a nice new Virtual Machine setup. And we can create a new one really simply by changing a couple of parameters.
You can find the full script example on GitHub here.
