[SOLVED] How to check whether an application pool exists or not in IIS using powershell and web administration module?

How to check whether an application pool exists or not in IIS using powershell and web administration module?

I am using powershell to automate configuring websites in my IIS. I have the following code that creates a web application pool for me

#Creating a new Application Pool
New-WebAppPool "NewAppPool"

But before creating the pool, I want to check whether pool exists or not.How do I go about doing this?

Please note : There is no IIS Drive on my system. And hence commands which have IIS mentioned in the path like the following fail :

$IISPath = "IIS:\AppPools"
cd $IISPath
if (Test-Path ".\NewAppPool") { Write-Host "NewAppPool exists." }

Solution

Use this:

import-module webadministration

$AppPoolName="NewAppPool"

if(Test-Path IIS:\AppPools\$AppPoolName)
{
"AppPool is already there"
return $true;
}
else
{
"AppPool is not present"
"Creating new AppPool"
New-WebAppPool "$AppPoolName" -Force
return $false;
}

Note: You need the WebAdministration module for Powershell. After importing you can use it. See the other ANSWER where I have mentioned about IIS drive
