Tutorial: Create and Manage Windows VMs with Azure PowerShell
Applies to: ✔️ Windows VMs
Azure virtual machines provide a fully configurable and flexible computing environment. This tutorial covers basic Azure virtual machine (VM) deployment tasks like selecting a VM size, selecting a VM image, and deploying a VM. You learn how to:
- Create and connect to a VM
- Select and use VM images
- View and use specific VM sizes
- Resize a VM
- View and understand VM state
Launch Azure local PowerShell
Open the Azure Powershell console and run the scripts listed below with Administrator priviledge.
Create resource group
Create a resource group with the New-AzResourceGroup command.
An Azure resource group is a logical container into which Azure resources are deployed and managed. A resource group must be created before a virtual machine. In the following example, a resource group named myResourceGroupVM is created in the ChinaEast region:
# Sign in the Microsoft Azure operated by 21Vianet
Connect-AzAccount -Environment AzureChinaCloud
New-AzResourceGroup `
-ResourceGroupName "myResourceGroupVM" `
-Location "ChinaEast"
The resource group is specified when creating or modifying a VM, which can be seen throughout this tutorial.
Create a VM
When creating a VM, several options are available like operating system image, network configuration, and administrative credentials. This example creates a VM named myVM, running the default version of Windows Server 2016 Datacenter.
Set the username and password needed for the administrator account on the VM with Get-Credential:
$cred = Get-Credential
Create the VM with New-AzVM.
New-AzVm `
-ResourceGroupName "myResourceGroupVM" `
-Name "myVM" `
-Location "ChinaEast" `
-VirtualNetworkName "myVnet" `
-SubnetName "mySubnet" `
-SecurityGroupName "myNetworkSecurityGroup" `
-PublicIpAddressName "myPublicIpAddress" `
-Credential $cred
Connect to VM
After the deployment has completed, create a remote desktop connection with the VM.
Run the following commands to return the public IP address of the VM. Take note of this IP Address so you can connect to it with your browser to test web connectivity in a future step.
Get-AzPublicIpAddress `
-ResourceGroupName "myResourceGroupVM" | Select IpAddress
Use the following command, on your local machine, to create a remote desktop session with the VM. Replace the IP address with the publicIPAddress of your VM. When prompted, enter the credentials used when creating the VM.
mstsc /v:<publicIpAddress>
In the Windows Security window, select More choices and then Use a different account. Type the username and password you created for the VM and then click OK.
Understand marketplace images
The Azure marketplace includes many images that can be used to create a new VM. In the previous steps, a VM was created using the Windows Server 2016 Datacenter image. In this step, the PowerShell module is used to search the marketplace for other Windows images, which can also be used as a base for new VMs. This process consists of finding the publisher, offer, SKU, and optionally a version number to identify the image.
Use the Get-AzVMImagePublisher command to return a list of image publishers:
Get-AzVMImagePublisher -Location "ChinaEast"
Use the Get-AzVMImageOffer to return a list of image offers. With this command, the returned list is filtered on the specified publisher named MicrosoftWindowsServer
:
Get-AzVMImageOffer `
-Location "ChinaEast" `
-PublisherName "MicrosoftWindowsServer"
The results will look something like this example:
Offer PublisherName Location
----- ------------- --------
Windows-HUB MicrosoftWindowsServer ChinaEast
WindowsServer MicrosoftWindowsServer ChinaEast
WindowsServer-HUB MicrosoftWindowsServer ChinaEast
The Get-AzVMImageSku command will then filter on the publisher and offer name to return a list of image names.
Get-AzVMImageSku `
-Location "ChinaEast" `
-PublisherName "MicrosoftWindowsServer" `
-Offer "WindowsServer"
The results will look something like this example:
Skus Offer PublisherName Location
---- ----- ------------- --------
2008-R2-SP1 WindowsServer MicrosoftWindowsServer ChinaEast
2008-R2-SP1-smalldisk WindowsServer MicrosoftWindowsServer ChinaEast
2012-Datacenter WindowsServer MicrosoftWindowsServer ChinaEast
2012-Datacenter-smalldisk WindowsServer MicrosoftWindowsServer ChinaEast
2012-R2-Datacenter WindowsServer MicrosoftWindowsServer ChinaEast
2012-R2-Datacenter-smalldisk WindowsServer MicrosoftWindowsServer ChinaEast
2016-Datacenter WindowsServer MicrosoftWindowsServer ChinaEast
2016-Datacenter-Server-Core WindowsServer MicrosoftWindowsServer ChinaEast
2016-Datacenter-Server-Core-smalldisk WindowsServer MicrosoftWindowsServer ChinaEast
2016-Datacenter-smalldisk WindowsServer MicrosoftWindowsServer ChinaEast
2016-Datacenter-with-Containers WindowsServer MicrosoftWindowsServer ChinaEast
2016-Datacenter-with-Containers-smalldisk WindowsServer MicrosoftWindowsServer ChinaEast
2016-Datacenter-with-RDSH WindowsServer MicrosoftWindowsServer ChinaEast
2016-Nano-Server WindowsServer MicrosoftWindowsServer ChinaEast
This information can be used to deploy a VM with a specific image. This example deploys a VM using the latest version of a Windows Server 2016 with Containers image.
New-AzVm `
-ResourceGroupName "myResourceGroupVM" `
-Name "myVM2" `
-Location "ChinaEast" `
-VirtualNetworkName "myVnet" `
-SubnetName "mySubnet" `
-SecurityGroupName "myNetworkSecurityGroup" `
-PublicIpAddressName "myPublicIpAddress2" `
-ImageName "MicrosoftWindowsServer:WindowsServer:2016-Datacenter-with-Containers:latest" `
-Credential $cred `
-AsJob
The -AsJob
parameter creates the VM as a background task, so the PowerShell prompts return to you. You can view details of background jobs with the Get-Job cmdlet.
Understand VM sizes
The VM size determines the amount of compute resources like CPU, GPU, and memory that are made available to the VM. Virtual machines should be created using a VM size appropriate for the workload. If a workload increases, an existing virtual machine can also be resized.
VM Sizes
The following table categorizes sizes into use cases.
Type | Common sizes | Description |
---|---|---|
General purpose | B, Dsv3, Dv3, DSv2, Dv2, Av2 | Balanced CPU-to-memory. Ideal for dev / test and small to medium applications and data solutions. |
Compute optimized | Fsv2 | High CPU-to-memory. Good for medium traffic applications, network appliances, and batch processes. |
Memory optimized | Esv3, Ev3, M, DSv2, Dv2 | High memory-to-core. Great for relational databases, medium to large caches, and in-memory analytics. |
GPU | NCv3 | Specialized VMs targeted for heavy graphic rendering and video editing. |
High performance | H | Our most powerful CPU VMs with optional high-throughput network interfaces (RDMA). |
Find available VM sizes
To see a list of VM sizes available in a particular region, use the Get-AzVMSize command.
Get-AzVMSize -Location "ChinaEast"
Resize a VM
After a VM has been deployed, it can be resized to increase or decrease resource allocation.
Before resizing a VM, check if the size you want is available on the current VM cluster. The Get-AzVMSize command returns a list of sizes.
Get-AzVMSize -ResourceGroupName "myResourceGroupVM" -VMName "myVM"
If the size is available, the VM can be resized from a powered-on state, however it is rebooted during the operation.
$vm = Get-AzVM `
-ResourceGroupName "myResourceGroupVM" `
-VMName "myVM"
$vm.HardwareProfile.VmSize = "Standard_DS3_v2"
Update-AzVM `
-VM $vm `
-ResourceGroupName "myResourceGroupVM"
If the size you want isn't available on the current cluster, the VM needs to be deallocated before the resize operation can occur. Deallocating a VM will remove any data on the temp disk, and the public IP address will change unless a static IP address is being used.
Stop-AzVM `
-ResourceGroupName "myResourceGroupVM" `
-Name "myVM" -Force
$vm = Get-AzVM `
-ResourceGroupName "myResourceGroupVM" `
-VMName "myVM"
$vm.HardwareProfile.VmSize = "Standard_E2s_v3"
Update-AzVM -VM $vm `
-ResourceGroupName "myResourceGroupVM"
Start-AzVM `
-ResourceGroupName "myResourceGroupVM" `
-Name $vm.name
VM power states
An Azure VM can have one of many power states.
Power State | Description |
---|---|
Starting | The virtual machine is being started. |
Running | The virtual machine is running. |
Stopping | The virtual machine is being stopped. |
Stopped | The VM is stopped. Virtual machines in the stopped state still incur compute charges. |
Deallocating | The VM is being deallocated. |
Deallocated | Indicates that the VM is removed from the hypervisor but is still available in the control plane. Virtual machines in the Deallocated state do not incur compute charges. |
- | The power state of the VM is unknown. |
To get the state of a particular VM, use the Get-AzVM command. Be sure to specify a valid name for a VM and resource group.
Get-AzVM `
-ResourceGroupName "myResourceGroupVM" `
-Name "myVM" `
-Status | Select @{n="Status"; e={$_.Statuses[1].Code}}
The output will look something like this example:
Status
------
PowerState/running
To retrieve the power state of all the VMs in your subscription, use the Virtual Machines - List All API with parameter statusOnly set to true.
Management tasks
During the lifecycle of a VM, you may want to run management tasks like starting, stopping, or deleting a VM. Additionally, you may want to create scripts to automate repetitive or complex tasks. Using Azure PowerShell, many common management tasks can be run from the command line or in scripts.
Stop a VM
Stop and deallocate a VM with Stop-AzVM:
Stop-AzVM `
-ResourceGroupName "myResourceGroupVM" `
-Name "myVM" -Force
If you want to keep the VM in a provisioned state, use the -StayProvisioned parameter.
Start a VM
Start-AzVM `
-ResourceGroupName "myResourceGroupVM" `
-Name "myVM"
Deleting VM resources
You can delete a VM, but by default this only deletes the VM resource, not the disks and networking resources the VM uses. You can change the default behavior to delete other resources when you delete the VM. For more information, see Delete a VM and attached resources.
