Deploy to IIS step - not creating app pool

amushtaq · 3 November 2021 12:03

Hi ,
I am pushing an application using the the '‘Deploy to IIS’ built in step.
But octopus fails to create the app pool, I am having to create it manually for the first time around.

Can you please check our logs and advice.

Many,
thanks

Hi @amushtaq

Thanks for reaching out!

It looks like the reason this doesn’t work with the New-Item cmdlet here:

github.com

OctopusDeploy/Calamari/blob/master/source/Calamari/Scripts/Octopus.Features.IISWebSite_BeforePostDeploy.ps1#L169

    
      
          {
          
          
	$appPoolPath = ("IIS:\AppPools\" + $applicationPoolName)
          
          
	# Set App Pool
          	Execute-WithRetry { 
          		Write-Verbose "Loading Application pool"
          		$exists = Test-Path $appPoolPath -ErrorAction SilentlyContinue
          		if (!$exists) { 
          			Write-Host "Application pool `"$applicationPoolName`" does not exist, creating..." 
          			New-Item $appPoolPath -confirm:$false
          		} else {
          			Write-Host "Application pool `"$applicationPoolName`" already exists"
          		}
                  # Confirm it's there. Get-Item can pause if the app-pool is suspended, so use Get-WebAppPoolState
                  $pool = Get-WebAppPoolState $applicationPoolName
          
          
		if ($startPool -eq $false) {
          			if ($pool.Value -eq "Started") {
          				Write-Host "Application pool is started. Attempting to stop..."
          				Stop-WebAppPool $applicationPoolName

Is to do with the fact your App Pool Name has a . at the start.

The easiest way to work around this would be to change this value for example instead of .NET v4.5 Resources Testing you could name it dotNet v4.5 Resources Testing.

I think this is a quirk with the way this cmdlet works, and therefore isn’t in Octopus’ control to change since it’s an IIS WebAdministration PowerShell cmdlet.

I hope that helps!
