AzureRm PowerShell Commands for scripting and management


This post will be short and sweet, but I wanted to write a quick post on some cool commands you can use for your scripts / to manage your Azure subscription. I recently found myself wanting to pull a list of all VMs running in my Azure subscription, but the way to do this using Azure Resource Management is slightly different from Azure Service Management.

Note: This will only pull a list of your Azure RM VMs.

$RGs = Get-AzureRMResourceGroup
foreach($RG in $RGs)
{
    $VMs = Get-AzureRmVM -ResourceGroupName $RG.ResourceGroupName
    foreach($VM in $VMs)
    {
        $VMDetail = Get-AzureRmVM -ResourceGroupName $RG.ResourceGroupName -Name $VM.Name -Status
        foreach ($VMStatus in $VMDetail.Statuses)
        { 
            if($VMStatus.Code -like "PowerState/*")
            {
                $VMStatusDetail = $VMStatus.DisplayStatus
            }
        }
        $out = new-object psobject
        $out | add-member noteproperty 'Virtual Machine Name' $VM.Name
        $out | add-member noteproperty Status $VMStatusDetail
        $out | add-member noteproperty 'Resource Group Name' $RG.ResourceGroupName
        Write-Output $out
    }
}



So, to explain the above, I used variables for the resource groups, the vms and status, and then stored the results in an object. The trick to easily format data in PowerShell is to parse the data into an object. I used the 'Write-Host' command to push the output of the created object in table format to the pipeline. I am able to do this easily (especially one with only 3 properties) because of how PowerShell's 'Format-Table' cmdlet works with objects.


Now, you might be wondering why you couldn't just use the 'Get-AzureRmVM' command and then pipe to 'Select-Object' and the answer is there is no longer an object for the running status information. Here is a current list of the objects you can use with that command:

Get-AzureRmVM | Select-Object
 
AvailabilitySetReference 
BootDiagnostics 
DataDiskNames
DiagnosticsProfile
Disks
Extensions
HardwareProfile
Id
InstanceView
LicenseType 
Location
Name
NetworkInterfaceIDs 
NetworkProfile 
OSProfile
Plan
PlatformFaultDomain
PlatformUpdateDomain
ProvisioningState
RemoteDesktopThumbprint
RequestId
ResourceGroupName
StatusCode
Statuses
StorageProfile
Tags
Type
VMAgent 



Notably, the 'Statuses' and 'StatusCode' does not display the running status of the VM.


Now, if you want to quickly get a list of your resource groups and other useful information about them you can use the following code:

#Get list of all resource groups, location, and provisioning state
Get-AzureRmResourceGroup | Select-Object ResourceGroupName, Location, ProvisioningState



The code above pulls a list of your resource groups and then displays the relevant information such as name, location and provisioning state.


If you have any other commands or code snippets you think others would find helpful, please feel free to leave a comment.
