The other day I tweeted a short bit of code on how to automate the zeroing-out of your VDI images using SDelete:
I got quite a few DMs afterwards asking if it was possible to do the same with VMware’s OS Optimization Tool.
So without further ado, here’s the code I use as the last step in my Packer builds before closing them down for svMotioning:
| $ErrorActionPreference = "Stop" | |
| $webserver = "webserver.contoso.local" | |
| $url = "http://" + $webserver | |
| $files = @("VMwareOSOptimizationTool.exe","VMwareOSOptimizationTool.exe.config","my_osot.xml") | |
| $exe = $files[0] | |
| $arg = "-o -t " + $files[2] | |
| # Verify connectivity | |
| if (Test-Connection $webserver –Quiet){ | |
| # Get the OSOT files | |
| ForEach ($file in $files) | |
| { | |
| Invoke-WebRequest –Uri ($url + "/" + $file) –OutFile $env:TEMP\$file | |
| } | |
| } else { | |
| throw "No connection to server. Aborting." | |
| } | |
| # Change to temp folder | |
| Set-Location $env:TEMP | |
| # Run OSOT | |
| Try | |
| { | |
| Start-Process $exe –ArgumentList $arg –Passthru –Wait –ErrorAction stop | |
| } | |
| Catch | |
| { | |
| Write-Error "Failed to run OSOT" | |
| Write-Error $_.Exception | |
| Exit -1 | |
| } | |
| # Delete files | |
| ForEach ($file in $files) | |
| { | |
| Remove-Item –Path $env:TEMP\$file –Confirm:$false | |
| } |
Please remember to swap out your web server and to specify your own XML file. You could also YOLO it and use one of the built-in templates…
…but don’t be surprised when you cripple half your apps 🙂
Those that follow my adventures with EUC will probably be aware that I’m a huge fan of Linux on the VDI desktop. The cost benefits are self-evident for task and knowledge-based workers; and for power users like developers, the platform can provide an easier route to a lot of their applications.
