Docker files with PowerShell syntax
As PowerShell comes pre-installed, Docker files can have PowerShell syntax.
This allows you to run scripts or cmdlets as part of your Docker file.
FROM mcr.microsoft.com/dotnet/core/sdk:3.0 RUN pwsh -c Get-Date RUN pwsh -c "Get-Module -ListAvailable | Select-Object -Property Name, Path"
Build scenarios in Docker
In addition to enabling PowerShell syntax, PowerShell scripts in the container can be easily invoked through Docker:
docker run -it -v c:\myrepo:/myrepo -w /myrepo mcr.microsoft.com/dotnet/core/sdk:3.0 pwsh ./build.ps1
The NuGet package for the global tool can be found at: https://www.nuget.org/packages/PowerShell/
