Nim Windows Container

This repository contains:

• A Dockerfile that builds a Windows Server Core Container with Nim and Mingw-w64 dependencies as a starting point for building Nim applications in Windows Containers.
• A GitHub Actions workflow for deploying the Windows Container to the GitHub Container Registry.

Nim

Nim is a compiled, garbage-collected systems programming language with a design that focuses on efficiency, expressiveness, and elegance.

• Learn Nim - Nim Tutorial
• Documentation - Nim Documentation
• Nim in Action - Book from Manning Publications
• What Is Nim? A brief introduction to the Nim programming language - YouTube video

Dockerfile

The sample Dockerfile defaults to:

• Windows Server 2022 LTSC.
• Nim 1.4.8, the current stable release of Nim. It is very likely by the time you are reading this that Nim has since been updated. Check nim-lang releases for the latest release.

GitHub Actions Workflow

This sample GitHub Actions workflow:

• Builds the Windows Container for both Windows Server 2019 LTSC and Windows Server 2022 LTSC. The default of Windows Server 2022 LTSC is overridden for 2019 LTSC builds by passing --build-arg win_version=ltsc2019 into the Dockerfile.
• Detects and downloads the latest version of Nim by communicating with the GitHub REST API: $nim_version = ((Invoke-RestMethod -Uri https://api.github.com/repos/nim-lang/Nim/tags).Name | Select-Object -first 1).Trim("v") and passing the most recent version into the Dockerfile as a build argument: --build-arg nim_version=$nim_version, overriding the default of 1.4.8.
• Pushes the resulting container to the GitHub Container Registry.

It is not currently possible to run Windows Containers on GitHub Actions at this time, the runner only supports Linux containers. :(

Windows Container

To use my builds:

Windows Server 2019

docker pull ghcr.io/sirredbeard/nim-windows-container/nimstable-ltsc2019:latest

GitHub Container Registry page.

Windows Server 2022

docker pull ghcr.io/sirredbeard/nim-windows-container/nimstable-ltsc2022:latest

GitHub Container Registry page.

Build Yourself

To build and use the Windows Container yourself, you can use the Dockerfile, or:

• Fork this repo
• Let GitHub build your own Windows Container
• Grab your GitHub Personal Access Token from here
• Give your PAT access to read packages

• Run

Set-Variable -Name "CR_PAT" -Value "<PAT>"
echo $CR_PAT | docker login ghcr.io -u USERNAME --password-stdin
docker pull ghcr.io/<USERNAME>/nim-windows-container/nimstable-ltsc2019:latest``
