Container.start.ps1

<# .SYNOPSIS Starts the container. .DESCRIPTION Starts a container. This script should be called from the Dockerfile as the ENTRYPOINT (or from within the ENTRYPOINT). It should be deployed to the root of the container image. ~~~Dockerfile # Thank you Microsoft! Thank you PowerShell! Thank you Docker! FROM mcr.microsoft.com/powershell # Set the shell to PowerShell (thanks again, Docker!) SHELL ["/bin/pwsh", "-nologo", "-command"] # Run the initialization script. This will do all remaining initialization in a single layer. RUN --mount=type=bind,src=./,target=/Initialize ./Initialize/Container.init.ps1 ENTRYPOINT ["pwsh", "-nologo", "-noexit", "-file", "/Container.start.ps1"] ~~~ .NOTES Did you know that in PowerShell you can 'use' namespaces that do not really exist? This seems like a nice way to describe a relationship to a container image. That is why this file is using the namespace 'mcr.microsoft.com/powershell'.
