How to Set Up a Docker Container with PowerShell on Windows?

Hey everyone! I'm trying to set up a Docker container using a Microsoft Windows image, and I need to make sure that PowerShell is included so I can run some specific scripts. Unfortunately, I'm running into a roadblock because PowerShell isn't readily available in the container. I'm currently using the Windows Server Core image (which should have PowerShell) but I'm considering a few approaches: 1. Using the server core image, 2. Downloading and installing PowerShell Core, or 3. Trying different base images. Here's the Dockerfile I'm working with: ```Dockerfile FROM mcr.microsoft.com/windows/servercore:ltsc2022 # Download PowerShell Core ADD https://github.com/PowerShell/PowerShell/releases/download/v7.4.1/PowerShell-7.4.1-win-x64.zip C:/PowerShell.zip # Extract PowerShell Core using PowerShell SHELL ["C:WindowsSystem32WindowsPowerShellv1.0powershell.exe", "-Command"] RUN Expand-Archive -Path C:PowerShell.zip -DestinationPath C:PowerShell; Remove-Item -Path C:PowerShell.zip # Set PowerShell Core as the shell SHELL ["C:PowerShellpwsh.exe", "-Command"] # Install MicrosoftTeams module RUN Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force; Set-PSRepository -Name PSGallery -InstallationPolicy Trusted; Install-Module -Name MicrosoftTeams -Force -AllowClobber # Set working directory WORKDIR C:/app # Copy script COPY service.ps1 . # Expose port EXPOSE 8081 # Run script CMD ["C:PowerShellpwsh.exe", "-File", "C:/app/service.ps1"] ```
