Setting variables in IIS using powershell

Question

Setting variables in IIS using powershell

trying to automate the configuration of a website, it is require to setup some environment variables for an netcore application.

I prepared the following script:

$env:sitename="MyApp"

$env:IMAGEDIRECTORYPATH="C:\Temp\Images\"
$env:REDISINSTANCENAME="DEV"
$env:CACHESERVERHOSTIP="192.168.0.1"
$env:QUEUEMACHINENAME="BOG11"
$env:QUEUESALGORITHMSQUEUE="BOG11\private$\Algorithms"

Import-Module WebAdministration

$envVariables = (
     @{name='SignalRHub';value="$env:IMAGEDIRECTORYPATH"},
     @{name='ApiServerUrl';value="$env:QUEUESALGORITHMSQUEUE"} 
)

$envVariables2 = (
     @{name='SignalRHub3';value="$env:IMAGEDIRECTORYPATH"},
     @{name='ApiServerUrl3';value="$env:QUEUESALGORITHMSQUEUE"} 
)

set-WebConfigurationProperty -pspath "MACHINE/WEBROOT/APPHOST/$env:SiteName"  -filter "system.webServer/aspNetCore/environmentVariables" -name "." -value $envVariables
set-WebConfigurationProperty -pspath "MACHINE/WEBROOT/APPHOST/$env:SiteName"  -filter "system.webServer/aspNetCore/environmentVariables" -name "." -value $envVariables2

I ran the script in Server A, it works perfectly.

then I ran the script in Server B, and I got this:

set-WebConfigurationProperty : The request is not supported. (Exception from HRESULT: 0x80070032)
At line:23 char:1

Server B was cloned from Server B.

What could cause this behavior?

powershell

Can you instead try this command:

Set-WebConfigurationProperty -pspath "MACHINE/WEBROOT/APPHOST" -location $env:sitename -filter "system.webServer/aspNetCore/environmentVariables" -name "." -value $envVars

I ran into the same problem. Worked on Development server, got the error described by the original poster on QA server. One is a clone of the other. The issue was that to test the QA server I first setup the site in IIS manually and entered the environment variable through the Configuration Editor in IIS manually. Running the script against that then failed as described. However, when I cleared the existing manually-entered configuration so that there were zero environment variables, the script using Set-WebConfigurationProperty to set the environment variables worked. I did not have to use the -Location parameter.

UPDATE: Spoke too soon. Turns out the same variable was set at the MACHINE/WEBROOT/APPHOST level. When clearing them out at the site level, the script worked but after that it broke again when updating on a subsequent deployment. For me the answer was to remove the duplicate environment variable at the APPHOST level if updating at the site level or updating at the APPHOST level instead of at the site level. Placing the variable at the APPHOST level, of course, would set that for all sites. Hope this helps.
