There a couple of ways
.
1. You can use "Generate an action from a PowerShell script" workflow.
This workflow generates vCO Action based on provided PS script.
When actions is generated from PS scripts you can use {#varname#} as placeholders which will be replaced before the scripts get's executed on PowerShell host.
The value can be provided from as action input parameter.
Check "samples\GenereateActionFromScript" folder for example of generated workflow and screenshot of how workflow was generated.
2. You can use "Invoke an external script" workflow to execute PS script that is already on PowerShell host machine.
Check "samples\InvokeExternalScript" for example of script receiving an argument and how it was invoked from vCO.
3. Invoke from scripting. Contains example how arbitrary powershell command can be invoked using vCO PowerShell scripting API.
Check "samples\Invoke from scripting".
note that for all examples I assume the hello.ps1 file is located in c:\temp folder.
