Need help in executing powershell commands in dockerized laravel - php

Question

I want to access vsphere config info from powercli script to laravel. But I do not know how to make them work together in docker. Whatever I do, the error is similar to this - The command "'pwsh' '-v'" failed. Exit Code: 127(Command not found) Working directory: /var/www/public Output: ================ Error Output: ================ sh: 1: exec: pwsh: not found
As a last resort, I am here.

Controller:
//$process = new Process(['ls', '-lsa']); #This works but next one do not
$process = new Process(['pwsh', '-v']);
$process->run();
// executes after the command finishes
if (!$process->isSuccessful()) {
throw new ProcessFailedException($process);
}
echo $process->getOutput();
I know how the Process() method works. Above code fails.
I need help on making powershell and laravel work together in docker.
Is there anything wrong with docker configuration or the controller code in accessing powershell.

Answer 1

You are using multistage build in Dockerfile. It can copy artifacts, but you don't copy anything. So pwsh app doesn't copy to PHP image (to the second stage).
You could remove first stage (FROM mcr.microsoft.com/powershell:latest) and install properly Powershell inside PHP image.
For example:
RUN apt-get update && apt-get install -y \
wget
RUN wget https://packages.microsoft.com/config/debian/10/packages-microsoft-prod.deb && \
dpkg -i packages-microsoft-prod.deb
RUN apt-get update && apt-get install -y \
powershell
PHP image use Debian 10, so here is the instruction: https://learn.microsoft.com/en-us/powershell/scripting/install/installing-powershell-core-on-linux?view=powershell-7.1#debian-10
Check pwsh inside container first:
docker exec -it app bash
pwsh

Thanks to #konstantin-bogomolov
The reason was the incorrect docker file. Powershell was not properly installed in container.
For those who stop by, Working dockerfile is below.
