Installing Azure powershell in an azure virtual machine

I need to write a powershell workflow that creates an Azure Virtual Machine and runs some blue cmdlets in that Azure Virtual Machine. But the newly created VM does not have any PowerShell modules in it. My code would be like this:

    New-AzureQuickVM -Windows -ServiceName $serviceName -Name $vmname -ImageName $VMImage  -Password $password -AdminUserName $username -InstanceSize "ExtraSmall" -WaitForBoot

    $WinRmUri = Get-AzureWinRMUri -ServiceName $serviceName -Name $vmname
    $Cred = new-object -typename System.Management.Automation.PSCredential -argumentlist $username, $password

    Invoke-Command -ConnectionUri $WinRmUri -Credential $Cred -ScriptBlock {
         Add-AzureAccount ......  ## These cmdlets need Azure Powershell Module 
         Set-AzureSubscription........
         New-AzureStorageAccount......
    }

I don't have to manually fetch the rdp of this VM and open it to install the Azure Powershell module, but to dynamically create the VM using the powershell cmdlet and install the azure module in that vm using the powershell itself.

This can be easily done using the ARM (Azure Resource Manager) template. This is a JSON template that defines objects to deploy. In your case, you will want to deploy a virtual machine with a custom script extension. After the virtual machine is initialized, the Azure Resource Manager will fetch the provided files and launch your own wrapper. See example below and replace the line https://<YOUR-BLOB-HERE>.blob.core.windows.net/resources/CUSTOM-POWERSHELL-SCRIPT.ps1

with your blob and powershell script. You can use the Azure Kernel Shell to run the script as described here: https://azure.microsoft.com/en-us/documentation/articles/powershell-azure-resource-manager/

The key cmdlet for your purposes is New-AzureResourceGroup. The call will look something like this:

Switch-AzureMode -Name AzureResourceManager
New-AzureResourceGroup -Name TestRG1 -Location "West US" -TemplateFile <YOUR-JSON-ARM-TEMPLATE>.json


See the list of ARM templates for reference: https://github.com/Azure/azure-quickstart-templates . Sample template to change to run custom code / install Azure powershell.

If your virtual machine has PowerShell 5.0, you can use the PowerShell gallery to install your modules. You will not require any of the steps mentioned in other answers. All you have to do is write the PowerShell script as usual. Just add the module from the PowerShell gallery using just one cmdlet.

You can use Install-Module to install a module from the gallery, or you can use Install-Script to install a sample script from the PowerShell Public Gallery.



You can even host your own modules in the gallery and install there.

You can use an Azure Automation service that implements your Powershell code in a workbook.

Although not a direct approach, I implemented this idea that satisfied my need.
