Researching the optimal; Implementing the practical

Author of 'PowerShell for Developers'


Microsoft PowerShell, Yaml and VSTS

The Microsoft VSTS team released the preview of “Build YAML definitions”. We can now move away from using a UI for creating build definitions and storing our Continuous Integration defintions in a file that gets checked into source control.

The ability to store your CI build in source control has been a long running request for VSTS

Wait there’s more

You can run full on PowerShell in a - powershell tag!

Hello World

In a new VSTS projcect create a .vsts-ci.yml, add this, commit and you’re off to the races.

It’ll even run on a build for macOS or Linux.

Access to many things

This version is running PowerShell 5.1, so, along side your code you can run your custom PowerShell scripts, functions and modules you build locally, in your CI/CD pipelines.

That spells Flexibility with a capital F!

    gmo -list azurerm

That’s access to 4259 PowerShell functions, 133 PowerShell modules, unfortunately an older version of the Azure PowerShell module.
