How to execute PowerShell script and launch .exe in Dockerfile entrypoint?

Question

I need to execute PowerShell-script and after launch nginx.exe in my Windows-container, so I've added an entrypoint to my Dockerfile as below:

ENTRYPOINT ["powershell", "C:\nginx\Configure-Nginx.ps1 && C:\nginx\nginx.exe"]

But it doesn't work.

I am noobie with PowerShell... How to make it correctly?

In principle (may not solve all of your problems): powershell.exe is the CLI of Windows PowerShell, where the pipeline-chaining && operator isn't supported (it requires PowerShell (Core) v7+; PowerShell (Core)'s CLI is pwsh.exe). To emulate &&, use C:\nginx\Configure-Nginx.ps1; if ($?) { C:\nginx\nginx.exe } — mklement0

Also, I think you must escape the backslashes in your array elements -> ENTRYPOINT ["powershell", "C:\\nginx\\Configure-Nginx.ps1; if ($?) { C:\\nginx\\nginx.exe }"] — mklement0

Thank you for comments, I've check my PowerShell version, you're right, I use 5.1, it doesn't support && operator — Denis Steinman

From what I see here you want to do two things:

Run powershell script before container starts
Do an entrypoint runing nginx from powershell

It translates to this:

CMD [ "powershell", "-c", "C:\nginx\Configure-Nginx.ps1" ]

ENTRYPOINT ["powershell", "C:\nginx\nginx.exe"]

Will Configure-Nginx.ps1 execute on docker run or docker build? I need it was on docker run.

I've posted a new little modified question that is more detailed. I hope it will help to understand my problem.
