Create a Custom Detection Script for Docker Desktop (PowerShell)


Microsoft Endpoint Manager Configuration Manager (MEMCM / SCCM) and Microsoft Intune use Detection Rules to determine the presence of Applications & Win32 Apps. The detection rules ensure that application installations only begin to run if the application is not already installed on the device. This article will serve as an informative guide and give you a clear understanding of how to create an updated custom detection script for each new version of Docker Desktop using PowerShell.

How to Create a Custom Detection Script for Docker Desktop

Docker Desktop (File Detection Method)

## Check for Docker Desktop (File Detection Method)
$DockerDesktopExe = (Get-ChildItem -Path "C:\Program Files\Docker\Docker\Docker Desktop.exe","C:\Program Files (x86)\Docker\Docker\Docker Desktop.exe" -ErrorAction SilentlyContinue)
$DockerDesktopExe.FullName
$DockerDesktopPath = $($DockerDesktopExe.FullName).Replace("C:\Program Files\","").Replace("C:\Program Files (x86)\","")
$FileVersion = (Get-Item -Path "$($DockerDesktopExe.FullName)" -ErrorAction SilentlyContinue).VersionInfo.FileVersion

## Create Text File with Docker Desktop File Detection Method
$FilePath = "C:\Windows\Temp\Docker_Desktop_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([String](Get-Item -Path `"`$Env:ProgramFiles\$DockerDesktopPath`",`"`${Env:ProgramFiles(x86)}\$DockerDesktopPath`" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge `"$FileVersion`"){"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "Exit 0"
Add-Content -Path "$FilePath" -Value "}"
Add-Content -Path "$FilePath" -Value "else {"
Add-Content -Path "$FilePath" -Value "Exit 1"
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath
  • Click Run Script (F5)
  • A text file will open with the Docker Desktop Detection Method script required to detect the current version of Docker Desktop that is installed on the device you are running the script from.

Example:

If([String](Get-Item -Path "$Env:ProgramFiles\Docker\Docker\Docker Desktop.exe","${Env:ProgramFiles(x86)}\Docker\Docker\Docker Desktop.exe" -ErrorAction SilentlyContinue).VersionInfo.FileVersion -ge "4.11.1.84025"){
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}

Docker Desktop (Registry Detection Method)

## Check for Docker Desktop (Registry Detection Method)
$DockerDesktop = Get-ChildItem -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall","HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | Get-ItemProperty | Where-Object {$_.DisplayName -match 'Docker Desktop' } | Select-Object -Property DisplayName, DisplayVersion, PSChildName
$DockerDesktop.DisplayVersion
$DockerDesktop.PSChildName

## Create Text File with Docker Desktop Registry Detection Method
$FilePath = "C:\Windows\Temp\Docker_Desktop_Detection_Method.txt"
New-Item -Path "$FilePath" -Force
Set-Content -Path "$FilePath" -Value "If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$($DockerDesktop.PSChildName)','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\$($DockerDesktop.PSChildName)' -Name DisplayVersion -ea SilentlyContinue) -ge '$($DockerDesktop.DisplayVersion)') {"
Add-Content -Path "$FilePath" -Value "Write-Host `"Installed`""
Add-Content -Path "$FilePath" -Value "Exit 0"
Add-Content -Path "$FilePath" -Value "}"
Add-Content -Path "$FilePath" -Value "else {"
Add-Content -Path "$FilePath" -Value "Exit 1"
Add-Content -Path "$FilePath" -Value "}"
Invoke-Item $FilePath
  • Click Run Script (F5)
  • A text file will open with the Docker Desktop Detection Method script required to detect the current version of Docker Desktop that is installed on the device you are running the script from.

Example:

If([Version](Get-ItemPropertyValue -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Docker Desktop','HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Docker Desktop' -Name DisplayVersion -ea SilentlyContinue) -ge '4.11.1') {
Write-Host "Installed"
Exit 0
}
else {
Exit 1
}
