function Invoke-CKAzVMActionRunCommand { <# .SYNOPSIS Run scripts within an Azure Windows or Linux VM. Author: Roberto Rodriguez (@Cyb3rWard0g) License: MIT Required Dependencies: None Optional Dependencies: None .DESCRIPTION Invoke-CKAzVMActionRunCommand is a simple PowerShell wrapper to run scripts within an Azure Windows or Linux VM. The original set of commands are action orientated. The updated set of commands, currently in Public Preview, are management orientated and enable you to run multiple scripts and has less restrictions. You should consider using this set of commands for situations where you need to run: * A small script to get a content from a VM * A script to configure a VM (set registry keys, change configuration) * A one time script for diagnostics .PARAMETER vmName Name of the Azure VM. .PARAMETER subscriptionId The subscription Id where the Azure VM is located. .PARAMETER resourceGroupName The name of the resource group where the Azure VM is located. .PARAMETER commandId The command Id. .PARAMETER script The command or script to execute. This could be one string with multi-line space characters or a file path. .PARAMETER parameters Parameters to pass to the script if needed. This needs to be a list of dictionaries/hashtables. For example: @(@{"name" = "processName"; "value" = "notepad"}) .PARAMETER accessToken Access token used to access the API. .LINK https://docs.microsoft.com/en-us/azure/virtual-machines/run-command-overview https://learn.microsoft.com/en-us/rest/api/compute/virtual-machines/run-command?tabs=HTTP https://github.com/Gerenios/AADInternals/blob/a0e824a25483abcd9fb670c463fdb0020f5cb5b3/AzureCoreManagement.ps1#L307 https://github.com/jagilber/powershellScripts/blob/master/azurerm/azure-rm-rest-vmss-run-command.ps1 .EXAMPLE $accessToken = $(az account get-access-token --resource=https://management.core.windows.net/ --query accessToken --output tsv) Invoke-CKAzVMActionRunCommand -vmName DC01 -subscriptionId XXXXX -resourceGroupName XXXX -commandId RunPowerShellScript -script "whoami" -accessToken $accessToken [+] Requesting execution of RunPowerShellScript Action RunCommand [+] Getting Azure-AsyncOperation Status URI https://management.azure.com/subscriptions/XXXX/providers/Microsoft.Compute/locations/eastus/operations/XXXX?p=XXXX&api-version=2022-11-01 [*] Action RunCommand xXXX has status of InProgress [*] Action RunCommand xXXX has status of InProgress [*] Action RunCommand xXXX has status of InProgress [+] Action RunCommand xXXXoutput code: ComponentStatus/StdOut/succeeded nt authority\system .EXAMPLE $accessToken = $(az account get-access-token --resource=https://management.core.windows.net/ --query accessToken --output tsv) $parameters = @(@{"name" = "processName"; "value" = "notepad"}) Invoke-CKAzVMActionRunCommand -vmName DC01 -subscriptionId XXXX -resourceGroupName XXXX -commandId RunPowerShellScript -script 'param($processName); Write-host "Process Name $processName"' -parameters $parameters -accessToken $accessToken [+] Requesting execution of RunPowerShellScript Action RunCommand [+] Getting Azure-AsyncOperation Status URI https://management.azure.com/subscriptions/XXXX/providers/Microsoft.Compute/locations/eastus/operations/XXXX?p=XXXX&api-version=2022-11-01 [*] Action RunCommand xXXX has status of InProgress [*] Action RunCommand xXXX has status of InProgress [*] Action RunCommand xXXX has status of InProgress [+] Action RunCommand xXXXoutput code: ComponentStatus/StdOut/succeeded Process Name notepad #> [cmdletbinding()] Param( [parameter(Mandatory = $true)] [Alias("ComputerName")] [String]$vmName, [Parameter(Mandatory=$True)] [String]$subscriptionId, [parameter(Mandatory = $true)] [String]$resourceGroupName, [parameter(Mandatory = $true)] [ValidateSet('RunPowerShellScript', 'RunShellScript')] [String]$commandId, [parameter(Mandatory = $true)] [string]$script, [parameter(Mandatory = $false)] [System.Collections.ArrayList]$parameters = [System.Collections.ArrayList]@(), [parameter(Mandatory = $true)] [String]$accessToken ) $Headers = @{ "Authorization" = "Bearer $AccessToken" "Content-Type" = "application/json" } if ([System.IO.File]::Exists($script)){ $scriptContent = [collections.arraylist]@([io.file]::readAllLines($script)) } else { $scriptContent = [collections.arraylist]@($script.split("`r`n", [stringsplitoptions]::removeEmptyEntries)) } $body = @{ "commandId" = $commandId "script" = $scriptContent } if ($parameters){ $body['parameters'] = $parameters } $params = @{ "Method" = "Post" "Uri" = "https://management.azure.com/subscriptions/$subscriptionId/resourceGroups/$resourceGroupName/providers/Microsoft.Compute/virtualMachines/$vmName/runCommand?api-version=2022-11-01" "Body" = $Body | ConvertTo-Json "Headers" = $Headers } try { Write-Host "[+] Requesting execution of $commandId Action RunCommand" $response = Invoke-WebRequest @params } catch { $statusCode = $_.Exception.Response.StatusCode.value__ Write-Error "[!] RunCommand Failed with $statusCode" $_.Exception.Message break } Write-Host "[+] Getting Azure-AsyncOperation Status URI" $statusUri = $response.Headers["Azure-AsyncOperation"] Write-Host $statusUri while($true){ $statusResponse = $(Invoke-WebRequest -UseBasicParsing -Uri $statusUri[0] -Headers $Headers).Content | ConvertFrom-Json Write-Host "[*] Action RunCommand $($statusResponse.name) has status of $($statusResponse.status)" if($statusResponse.status -eq "InProgress"){ Start-Sleep -Seconds 5 continue } elseif ($statusResponse.status -eq "Succeeded"){ $output = $statusResponse.properties.output.value foreach ($item in $output){ if(-not [string]::IsNullOrEmpty($item.message) -and -not [string]::IsNullOrWhiteSpace($item.message)) { write-host "[+] Action RunCommand $($statusResponse.name) output code: $($item.code)" Write-Host $item.message } } } else { write-error "[!] Action RunCommand $($statusResponse.name) did not succeed!" } break } } |
