Azure – Provision Azure Virtual Machine with UnManaged disks

Microsoft has introduced a new type of disk called “Managed” disk wherein Azure manages the disk and the underlying storage account overhead for you. And, Microsoft recommends you create Azure virtual machines with “managed” disks, which is straightforward.

However, you might come across scenarios where your organization/client may require creating an Azure virtual machine with “unmanaged” disks. Use the below code to create an Azure virtual machine with “unmanaged” disks.

$location = "EastUS2"
$rgname = "manjuResourceGroup"
New-AzureRmResourceGroup -Name manjuResourceGroup -Location $location

# Create a subnet configuration
$subnetConfig = New-AzureRmVirtualNetworkSubnetConfig -Name mySubnet -AddressPrefix 192.168.1.0/24

# Create a virtual network
$vnet = New-AzureRmVirtualNetwork -ResourceGroupName manjuResourceGroup -Location $location `
    -Name MYvNET -AddressPrefix 192.168.0.0/16 -Subnet $subnetConfig

# Create a public IP address and specify a DNS name
$pip = New-AzureRmPublicIpAddress -ResourceGroupName manjuResourceGroup -Location $location `

    -AllocationMethod Static -IdleTimeoutInMinutes 4 -Name "mypublicdns$(Get-Random)"

# Create an inbound network security group rule for port 3389
$nsgRuleRDP = New-AzureRmNetworkSecurityRuleConfig -Name myNetworkSecurityGroupRuleRDP  -Protocol Tcp `
    -Direction Inbound -Priority 1000 -SourceAddressPrefix '125.16.236.160' -SourcePortRange * -DestinationAddressPrefix * `
    -DestinationPortRange 3389 -Access Allow

# Create an inbound network security group rule for port 80
$nsgRuleWeb = New-AzureRmNetworkSecurityRuleConfig -Name myNetworkSecurityGroupRuleWWW  -Protocol Tcp `
    -Direction Inbound -Priority 1001 -SourceAddressPrefix '125.16.236.160' -SourcePortRange * -DestinationAddressPrefix * `
    -DestinationPortRange 80 -Access Allow

# Create a network security group
$nsg = New-AzureRmNetworkSecurityGroup -ResourceGroupName manjuResourceGroup -Location $location `
    -Name myNetworkSecurityGroup -SecurityRules $nsgRuleRDP,$nsgRuleWeb

# Create a virtual network card and associate with public IP address and NSG
$nic = New-AzureRmNetworkInterface -Name myNic -ResourceGroupName manjuResourceGroup -Location $location `
    -SubnetId $vnet.Subnets[0].Id -PublicIpAddressId $pip.Id -NetworkSecurityGroupId $nsg.Id

# Define a credential object
$cred = Get-Credential

#VM config
$vmsize = "Standard_DS2"
$vmName="myVM"
$vm = New-AzureRmVMConfig -VMName $vmName -VMSize $vmSize
$pubName = ”MicrosoftWindowsServer”
$offerName = ”WindowsServer”
$skuName = ”2016-Datacenter”
$vm = Set-AzureRmVMOperatingSystem -VM $vm -Windows -ComputerName $vmName -Credential $cred
$vm = Set-AzureRmVMSourceImage -VM $vm -PublisherName $pubName -Offer $offerName -Skus $skuName -Version "latest"
$vm = Add-AzureRmVMNetworkInterface -VM $vm -Id $NIC.Id

# Create a new storage account
New-AzureRmStorageAccount -ResourceGroupName "manjuResourceGroup" -AccountName "manjustorageaccount" -Location $location -SkuName "Standard_LRS"

# Disk setup
$diskName = ”manju-disk”
$storageaccount = "manjustorageaccount"
$STA = Get-AzureRmStorageAccount -ResourceGroupName $rgName -Name $storageAccount
$OSDiskUri = $STA.PrimaryEndpoints.Blob.ToString() + "vhds/" + $diskName? + ".vhd"
$vm = Set-AzureRmVMOSDisk -VM $vm -Name $diskName -VhdUri $OSDiskUri -CreateOption fromImage

# Create the virtual machine
New-AzureRmVM -ResourceGroupName manjuResourceGroup -Location $location -VM $vm
