Help me please

sixeyed commented 7 years ago

Hi @NikitaEgorov - can you post some more information please, the whole output of the command would be useful (you can obscure any secret details, it's just the flow of commands I'd like to see).

@sixeyed

I have VM image Win2008r2Std-Gen1_boot.vhdx

execute this command PS C:\> ConvertTo-Dockerfile -ImagePath D:\Win2008r2Std-Gen1_boot.vhdx -Artifact IIS -Verbose -OutputPath d:\iis7

And get result

@sixeyed

I catch it

Generate_IIS:165

if ($sourcePath -ne $mainVirtualDir.PhysicalPath) {
                    ProcessDirectory -DirectoryBuilder $DirectoryBuilder -CopyBuilder $CopyBuilder -SourcePath $sourcePath                  
                }

AclBuilder is null

andreputera commented 7 years ago

hi @NikitaEgorov , did you find a solution for this issue?

NikitaEgorov commented 7 years ago

@andreputera Yes! See PR #55

andreputera commented 7 years ago

Thanks @NikitaEgorov

andreputera commented 7 years ago

I'm still having the same problems even after adding the "-AclBuilder $AclBuilder" at lines 165 and 192.

Update: I close the powershell prompt and restarted Docker, now it works, no errors. Now trying to build it

pulla2908 commented 7 years ago

I have a possible fix for this. I am creating a PR.

automatecloud commented 6 years ago

Getting the same error:

ConvertTo-Dockerfile -ImagePath D:\disk\DEV-SRV-N1.VHDX -Artifact iis -OutputPath C:\i2d2 -Verbose

Generate_IIS : You cannot call a method on a null-valued expression. At C:\Program Files\WindowsPowerShell\Modules\Image2Docker\1.8.5\Functions\Private\GenerateDockerfile.ps1:34 char:23

How can I fix this?

DanielTheCoder commented 6 years ago

@automatecloud have you applied the patch from @pulla2908, his PR is not yet merged?

automatecloud commented 6 years ago

@DanielTheCoder no, I had this bug during a POC a month ago and the POC is done so far as we did a manual creation of the Dockerfile. So not possible to check if the patch from @pulla2908 will help. I can't confirm that.

sixeyed commented 6 years ago

That's the problem with this issue, I haven't been able to reliably replicate it, so I want to spend some more time with the PR before merging.

DanielTheCoder commented 6 years ago

I see. @pulla2908 were able to reproduce the problem if you have a website with a virtual directory which is not placed under wwwroot. Maybe this helps to reproduce the problem?

cbmdk commented 6 years ago

I have the same config as @DanielTheCoder. my website as virtual applications which are not directly under the wwwroot but in a customers folder another place. And I get the same error :(

jhoward321 commented 6 years ago

Are there any updates on this? I have a site that is not under wwwroot and get the error every time. Looks like the pull requests are just waiting to be merged?

jcchristensen74 commented 6 years ago

It seems any site with a Web Application under it gets the Generate_IIS error, sites with no Web Apps completes and creates a Dockerfile. Is there a workaround to get a site with a Web application to complete and create a Dockerfile?

hreiner commented 6 years ago

Hello, I also had the same issue, and applying the Pr #55 from @NikitaEgorov fixed the problem (thanks by the way). Hadrien
