Run GitHub Actions Workflows On Windows Server and PowerShell

Since the release of GitHub, Actions Microsoft has made Windows Server runners available to run workflows with PowerShell available.

This post will show how to use Windows Server 2016, 2019 and the latest release with GitHub Actions.

Windows Runner

To run workflows on Windows runners, we need to specify in the workflow that we need to run the workflow on a Windows machine.

Currently, GitHub Actions offer the following Windows runner:

Runner nameDescription
windows-2016Windows Server 2016
windows-2019Windows Server 2019
Windows-latestLatest Windows server release
Windows Server Runners

Workflow

In the following workflow example, I am using a Windows Server 2019 build to run a workflow that runs PowerShell commands.

Note: All Windows Server runners run PowerShell 7.1.3

The below code run a few PowerShell command, and a Docker run commands the pull a Windows IIS image and runs it inside the runner.
