you can create a Powershell Function App like this:

using PowerShell modules

currently, you can’t install a powershell module inside Azure Function App, but you can upload your module to the script directory and access it from there. to do this, use Kudu:

 

browse to site / wwwroot:

then you can drag and drop your module ZIP-file to the right part of the explorer

the file will be uploaded and unpacked automatically

now you can reference this module directly from your function script
