This post will demo how to run remote PowerShell to an Azure vm. It’s either can from Azure Automation Portal or from a vm that running in Azure. This includes set up the connection to an Azure VM as well as call a command inside of an Azure API.
Before you get started, you need to make sure to install two modules from Azure Runbook Gallery (Thanks to the System Center Automation Team)
One is Connect-AzureVM, the other is Invoke-PSCommandSample.
Install and publish those two modules, and then run a command like below:
1 2 3 4 5 6
|
Invoke-PSCommandSample -AzureSubscriptionName "Visual Studio Premium with MSDN" ` -ServiceName "DEMO" ` -VMName "DC01" ` -VMCredentialName "VMDomainCred" ` -PSCommand "Get-WindowsFeature" ` -AzureOrgIdCredential $Cred
|
If you cannot find the module, please use the following:
Connect-AzureVM:

<# .SYNOPSIS Sets up the connection to an Azure VM
.DESCRIPTION This runbook sets up a connection to an Azure virtual machine. It requires the Azure virtual machine to have the Windows Remote Management service enabled, which is the default. It sets up a connection to the Azure subscription and then imports the certificate used for the Azure VM so remote PowerShell calls can be made to it.
.PARAMETER AzureSubscriptionName Name of the Azure subscription to connect to .PARAMETER AzureOrgIdCredential A credential containing an Org Id username / password with access to this Azure subscription.
If invoking this runbook inline from within another runbook, pass a PSCredential for this parameter.
If starting this runbook using Start-AzureAutomationRunbook, or via the Azure portal UI, pass as a string the name of an Azure Automation PSCredential asset instead. Azure Automation will automatically grab the asset with that name and pass it into the runbook.
.PARAMETER ServiceName Name of the cloud service where the VM is located.
.PARAMETER VMName Name of the virtual machine that you want to connect to
.EXAMPLE Connect-AzureVM -AzureSubscriptionName "Visual Studio Ultimate with MSDN" -ServiceName "Finance" -VMName "WebServer01" -AzureOrgIdCredential $cred

<# .SYNOPSIS This runbook calls a command inside of an Azure VM
.DESCRIPTION This runbook connects into an Azure virtual machine and runs the PowerShell command passed in. It has a dependency on the Connect-AzureVM runbook to set up the connection to the virtual machine before the command can be run.
.PARAMETER AzureSubscriptionName Name of the Azure subscription to connect to .PARAMETER AzureOrgIdCredential A credential containing an Org Id username / password with access to this Azure subscription.
If invoking this runbook inline from within another runbook, pass a PSCredential for this parameter.
If starting this runbook using Start-AzureAutomationRunbook, or via the Azure portal UI, pass as a string the name of an Azure Automation PSCredential asset instead. Azure Automation will automatically grab the asset with that name and pass it into the runbook. .PARAMETER ServiceName Name of the cloud service where the VM is located.
.PARAMETER VMName Name of the virtual machine that you want to connect to
.PARAMETER VMCredentialName Name of a PowerShell credential asset that is stored in the Automation service. This credential should have access to the virtual machine. .PARAMETER PSCommand PowerShell command that you want to run inside the Azure virtual machine.
.EXAMPLE Invoke-PSCommandSample -AzureSubscriptionName "Visual Studio Ultimate with MSDN" -ServiceName "Finance" -VMName "WebServer01" -VMCredentialName "FinanceCredentials" -PSCommand "ipconfig /all" -AzureOrgIdCredential $cred
