Add-AccountToDockerAccess fails in pwsh 7.0

[epvanhouten]

When running in pwsh 7.0 the following errors are generated:

InvalidOperation: C:\Users\CpUser\Documents\PowerShell\Modules\dockeraccesshelper\0.0.3\Add-AccountToDockerAccess.psm1:65

Running Add-AccountToDockerAccess in a powershell session with version 5.1.17763.1007 runs to completion successfully.

Thanks for opening the issue. As PS 7 is using .net Core, I probably need to use different classes and / or methods. Unfortunately, I won't have time for that in the foreseeable future but would keep this issue open as a reminder

I got this same error while using Powershell (Preview) 7.1.3.

The Solution

Open up the standard Powershell (5.1 or something), and try again. For me, it worked using the regular Powershell.

You should also be able to do this from pwsh:

powershell Install-Module -Name dockeraccesshelper
powershell Add-AccountToDockerAccess $UserName

as Admin user in powershell 7 i've done it with this command:

> $acl = Get-Acl "\\.\pipe\docker_engine"
> $acl.access

FileSystemRights  : FullControl
AccessControlType : Allow
IdentityReference : AUTORITE NT\Système
IsInherited       : False

> $rule = New-Object System.Security.AccessControl.FileSystemAccessRule("<Domain>\<user>","FullControl","Allow")
> $acl.SetAccessRule($rule)
> $acl.Access
