How to run Powershell script in DockerFile?

To run a PS1 script file, you can do something like this:

SHELL ["cmd", "/S", "/C"]    
RUN powershell -noexit "& ""C:\Chocolatey\lib\chocolatey.0.10.8\tools\chocolateyInstall.ps1"""

You can also do:

SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'SilentlyContinue';"]
WORKDIR C:\
RUN .\install_pfx.ps1

You can use RUN.

You can RUN poweshell commands using

RUN powershell -Command Add-WindowsFeature Web-Server

Refer https://learn.microsoft.com/en-us/dotnet/standard/containerized-lifecycle-architecture/design-develop-containerized-apps/set-up-windows-containers-with-powershell

Yes, there is another command. ENTRYPOINT ["executable", "param1", "param2"] is a command that, according to the documentation, will make the container to run the executable on its start. It can be used alongside with CMD.

I had a similar problem which I solved by using the shell directive.

FROM mcr.microsoft.com/windows/servercore:20H2 AS PS
SHELL ["powershell"]
RUN Write-Host "Hello from docker! Today is $(Get-Date)"

Edit: Just noticed the answer above has a bit better of a command than mine. Upvote it! https://stackoverflow.com/a/48804143/190831

I tried this one and it worked,

FROM mcr.microsoft.com/powershell 
WORKDIR /app
COPY . /app
CMD ["pwsh", "-File", "<your_powershellscript>"]

Here we need to mention the executable as pwsh not powershell, For your reference attaching the Github code link: Here(line: 39) Here (line: 56)
