Need to trigger the Update from Azure Update Manager within single action

Question

I need to trigger updates from Azure Update Manager with a single action.

Specifically, I need to trigger updates for a target computer, a group, all computers, or a list of computers by copying and pasting hostnames into a text box. This could potentially be done using a PowerShell script to pass a CSV file to trigger the AUM update.

I want to trigger the updates based on specific requirements by passing hostnames or group names, rather than doing the process manually. I would appreciate any suggestions for possible solutions.

Thanks in advance.

Hi Robin Hitch
Welcome to Microsoft Q&A, Thanks asking question here...!
To automate the process of triggering updates in Azure Update Manager (AUM) for a target computer, a group, all computers, or a list of computers using PowerShell, you can leverage Azure Automation and the Az module. Here is an approach to achieve this:

1.Create a PowerShell script that will read hostnames from a CSV file and trigger updates for those computers.

# Import the Az module
Import-Module Az

# Authenticate to Azure
Connect-AzAccount

# Define the resource group and automation account
$resourceGroupName = "YourResourceGroupName"
$automationAccountName = "YourAutomationAccountName"

# Function to trigger updates for a specific computer
function Trigger-Update($computerName) {
    $jobParams = @{
        ResourceGroupName = $resourceGroupName
        AutomationAccountName = $automationAccountName
        ConfigurationName = "UpdateManagement"
        Parameters = @{
            ComputerName = $computerName
        }
    }

    $job = Start-AzAutomationDscNodeConfiguration @jobParams
    Write-Output "Triggered update for $computerName. Job ID: $($job.JobId)"
}

# Read hostnames from CSV file
$computers = Import-Csv -Path "C:\path\to\hostnames.csv"

# Trigger updates for each computer
foreach ($computer in $computers) {
    Trigger-Update -computerName $computer.Hostname

2.Ensure your CSV file (e.g., hostnames.csv) has a format like this.
Hostname
computer1.domain.com
computer2.domain.com
group1
group2

3.Save the script to a .ps1 file and execute it in PowerShell. Make sure the path to the CSV file is correct.
4.For groups, you may need to add additional logic in the Trigger-Update function to handle group-specific updates. For all computers, you might want to list all computers in your Azure Update Manager setup and trigger updates for each.

# Example: Trigger updates for all computers in a specific group
function Trigger-UpdateForGroup($groupName) {
    $computersInGroup = Get-ComputersInGroup -groupName $groupName  # Define this function based on your setup
    foreach ($computer in $computersInGroup) {
        Trigger-Update -computerName $computer
    }
}

5.schedule this PowerShell script to run at specific intervals using Azure Automation or Windows Task Scheduler to ensure updates are triggered automatically.

Using this approach, you can automate the process of triggering updates in Azure Update Manager for specific computers, groups, or lists of computers, thereby eliminating the need for manual intervention.
