I know that we all write PowerShell modules every day to automate the world, but do you publish them to PowerShell Gallery so that the others can take advantage of your work.
To optimize the workload, I automated the process by using Visual Studio Team Services (VSTS) extension.
What is PowerShell Gallery?
In case you don’t know about PowerShell Gallery, it’s a central repository for all PowerShell module which Microsoft hosts. If you are using PowerShell v5.0 or PowerShellGet, then you can simply use Find-Module and Install-Module to find and get modules from PowerShell window, so that you don’t need to open web browser to find desired modules anymore.
To publish the module manually, you can use Publish-Module cmdlet, which requires API Key. So please register yourself first at https://www.powershellgallery.com/
You need API Key to publish modules.
1. Sign in to https://www.powershellgallery.com/
2. Click your account on right top of the page.
3. Obtain API key in Credentials section.
Use Publish-Module cmdlet. https://msdn.microsoft.com/en-us/powershell/reference/5.1/powershellget/publish-module
Automate the publish
No, I don’t want to publish the module manually every time. So in this article, I explain how you can use GitHub to host your source code and use VSTS to publish the module to Gallery in DevOps fashion. Oh, you don’t have VSTS account? Sign up at https://www.visualstudio.com/team-services/
Create a repository at GitHub, and check in psm1 and psd1 files as well as any dependencies. If you love to use VSTS as source repo, go ahead to use it <3

8. Select your account and click [Continue].
9. Go back to the release definition and add the installed task.
10. Enter API Key and select Module Folder by clicking more menu (…).
11. Modify the name by clicking pencil icon next to its name.
Test the release
1. Click [Release] | [Create Release].
2. Simply click [Create]
3. Select the release definition you just created in left pane. Then you can find Release which you added right now.
4. When I tested, I see the following error, which indicates I already have same version of the module.
2017-04-18T11:52:18.2341643Z ##[error]System.InvalidOperationException: Module ‘Microsoft.PowerBI.PowerShell’ with version ‘1.2’ cannot be published. The version must exceed the current version ‘1.2’ that exists in the repository ‘https://www.powershellgallery.com/api/v2/’.
To test all processes, you simply update your code and check-in to the GitHub repo.
