Remove-IISSite not working

[JohanSpannare]

Remove-IISSite -Name 'Default Web Site' is not working if executed during build of image. However Remove-WebSite -Name 'Default Web Site' works fine.

Same for Start-IISSite and Stop-IISSite.

if executed during build of image.

You mean within the docker file the calls to those Cmdlets fail? @mcy94w please take a look.

[JohanSpannare]

Yes, if you try execute the commands in the dockerfile (docker build)

[bariscaglar]

Can you please share your dockerfile?

Hi @JohanSpannare :

I tried the command remove-IISSIte -name 'Default Web Site' -confirm:$false; and Start-IISSite -name 'Default Web Site'; And they both worked. Could you please share you dockerfile so we can repro the issue?

Thanks

Here is an example:

If i do this manually it works.

docker run -it --entrypoint powershell -t microsoft/iis:nanoserver-sac2016

I can confirm that the -confirm:$false solves the "Remove-IISSite : Object reference not set to an instance of an object." error.

Havent tried start and stop sites yet.

Same happens to me!

It's weird, this command works flawlessly: Get-IISConfigSection -SectionPath "system.webServer/defaultDocument" | Get-IISConfigCollection -CollectionName "files" | New-IISConfigCollectionElement -ConfigAttribute @{"Value" = "MyDefDoc.htm"};

However this one needs the -confirm:$false

Get-IISConfigSection -SectionPath "system.webServer/defaultDocument" | Get-IISConfigCollection -CollectionName "files" | Remove-IISConfigCollectionElement -ConfigAttribute @{"Value" = "iisstart.htm"} -confirm:$false;
